HG(1) Mercurial Manual HG(1)NAME
hg - Mercurial source code management system
SYNOPSIS
hg command [option]... [argument]...
DESCRIPTION
The hg command provides a command line interface to the Mercurial sys‐
tem.
COMMAND ELEMENTS
files...
indicates one or more filename or relative path filenames; see
File Name Patterns for information on pattern matching
path indicates a path on the local machine
revision
indicates a changeset which can be specified as a changeset
revision number, a tag, or a unique substring of the changeset
hash value
repository path
either the pathname of a local repository or the URI of a remote
repository.
OPTIONS-R, --repository
repository root directory or name of overlay bundle file
--cwd change working directory
-y, --noninteractive
do not prompt, automatically pick the first choice for all
prompts
-q, --quiet
suppress output
-v, --verbose
enable additional output
--config
set/override config option (use 'section.name=value')
--debug
enable debugging output
--debugger
start debugger
--encoding
set the charset encoding (default: ascii)
--encodingmode
set the charset encoding mode (default: strict)
--traceback
always print a traceback on exception
--time time how long the command takes
--profile
print command execution profile
--version
output version information and exit
-h, --help
display help and exit
COMMANDS
add
hg add [OPTION]... [FILE]...
Schedule files to be version controlled and added to the repository.
The files will be added to the repository at the next commit. To undo
an add before that, see hg forget.
If no names are given, add all files to the repository.
An example showing how new (unknown) files are added automatically by
hg add:
$ ls
foo.c
$ hg status
? foo.c
$ hg add
adding foo.c
$ hg status
A foo.c
Returns 0 if all files are successfully added.
Options:
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-S, --subrepos
recurse into subrepositories
-n, --dry-run
do not perform actions, just print output
addremove
hg addremove [OPTION]... [FILE]...
Add all new files and remove all missing files from the repository.
New files are ignored if they match any of the patterns in .hgignore.
As with add, these changes take effect at the next commit.
Use the -s/--similarity option to detect renamed files. With a parame‐
ter greater than 0, this compares every removed file with every added
file and records those similar enough as renames. This option takes a
percentage between 0 (disabled) and 100 (files must be identical) as
its parameter. Detecting renamed files this way can be expensive. After
using this option, hg status -C can be used to check which files were
identified as moved or renamed. If this option is not specified, only
renames of identical files are detected.
Returns 0 if all files are successfully added.
Options:
-s, --similarity
guess renamed files by similarity (0<=s<=100)
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-n, --dry-run
do not perform actions, just print output
annotate
hg annotate [-r REV] [-f] [-a] [-u] [-d] [-n] [-c] [-l] FILE...
List changes in files, showing the revision id responsible for each
line
This command is useful for discovering when a change was made and by
whom.
Without the -a/--text option, annotate will avoid processing files it
detects as binary. With -a, annotate will annotate the file anyway,
although the results will probably be neither useful nor desirable.
Returns 0 on success.
Options:
-r, --rev
annotate the specified revision
--follow
follow copies/renames and list the filename (DEPRECATED)
--no-follow
don't follow copies and renames
-a, --text
treat all files as text
-u, --user
list the author (long with -v)
-f, --file
list the filename
-d, --date
list the date (short with -q)
-n, --number
list the revision number (default)
-c, --changeset
list the changeset
-l, --line-number
show line number at the first appearance
-w, --ignore-all-space
ignore white space when comparing lines
-b, --ignore-space-change
ignore changes in the amount of white space
-B, --ignore-blank-lines
ignore changes whose lines are all blank
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
aliases: blame
archive
hg archive [OPTION]... DEST
By default, the revision used is the parent of the working directory;
use -r/--rev to specify a different revision.
The archive type is automatically detected based on file extension (or
override using -t/--type).
Examples:
· create a zip file containing the 1.0 release:
hg archive -r 1.0 project-1.0.zip
· create a tarball excluding .hg files:
hg archive project.tar.gz -X ".hg*"
Valid types are:
files
a directory full of files (default)
tar
tar archive, uncompressed
tbz2
tar archive, compressed using bzip2
tgz
tar archive, compressed using gzip
uzip
zip archive, uncompressed
zip
zip archive, compressed using deflate
The exact name of the destination archive or directory is given using a
format string; see hg help export for details.
Each member added to an archive file has a directory prefix prepended.
Use -p/--prefix to specify a format string for the prefix. The default
is the basename of the archive, with suffixes removed.
Returns 0 on success.
Options:
--no-decode
do not pass files through decoders
-p, --prefix
directory prefix for files in archive
-r, --rev
revision to distribute
-t, --type
type of distribution to create
-S, --subrepos
recurse into subrepositories
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
backout
hg backout [OPTION]... [-r] REV
Prepare a new changeset with the effect of REV undone in the current
working directory.
If REV is the parent of the working directory, then this new changeset
is committed automatically. Otherwise, hg needs to merge the changes
and the merged result is left uncommitted.
Note backout cannot be used to fix either an unwanted or incorrect
merge.
By default, the pending changeset will have one parent, maintaining a
linear history. With --merge, the pending changeset will instead have
two parents: the old parent of the working directory and a new child of
REV that simply undoes REV.
Before version 1.7, the behavior without --merge was equivalent to
specifying --merge followed by hg update --clean . to cancel the merge
and leave the child of REV as a head to be merged separately.
See hg help dates for a list of formats valid for -d/--date.
Returns 0 on success.
Options:
--merge
merge with old dirstate parent after backout
--parent
parent to choose when backing out merge (DEPRECATED)
-r, --rev
revision to backout
-t, --tool
specify merge tool
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-m, --message
use text as commit message
-l, --logfile
read commit message from file
-d, --date
record the specified date as commit date
-u, --user
record the specified user as committer
bisect
hg bisect [-gbsr] [-U] [-c CMD] [REV]
This command helps to find changesets which introduce problems. To use,
mark the earliest changeset you know exhibits the problem as bad, then
mark the latest changeset which is free from the problem as good.
Bisect will update your working directory to a revision for testing
(unless the -U/--noupdate option is specified). Once you have performed
tests, mark the working directory as good or bad, and bisect will
either update to another candidate changeset or announce that it has
found the bad revision.
As a shortcut, you can also use the revision argument to mark a revi‐
sion as good or bad without checking it out first.
If you supply a command, it will be used for automatic bisection. Its
exit status will be used to mark revisions as good or bad: status 0
means good, 125 means to skip the revision, 127 (command not found)
will abort the bisection, and any other non-zero exit status means the
revision is bad.
Some examples:
· start a bisection with known bad revision 12, and good revision 34:
hg bisect --bad 34
hg bisect --good 12
· advance the current bisection by marking current revision as good or
bad:
hg bisect --good
hg bisect --bad
· mark the current revision, or a known revision, to be skipped (eg. if
that revision is not usable because of another issue):
hg bisect --skip
hg bisect --skip 23
· forget the current bisection:
hg bisect --reset
· use 'make && make tests' to automatically find the first broken revi‐
sion:
hg bisect --reset
hg bisect --bad 34
hg bisect --good 12
hg bisect --command 'make && make tests'
· see all changesets whose states are already known in the current
bisection:
hg log -r "bisect(pruned)"
· see all changesets that took part in the current bisection:
hg log -r "bisect(range)"
· with the graphlog extension, you can even get a nice graph:
hg log --graph -r "bisect(range)"
See hg help revsets for more about the bisect() keyword.
Returns 0 on success.
Options:
-r, --reset
reset bisect state
-g, --good
mark changeset good
-b, --bad
mark changeset bad
-s, --skip
skip testing changeset
-e, --extend
extend the bisect range
-c, --command
use command to check changeset state
-U, --noupdate
do not update to target
bookmarks
hg bookmarks [-f] [-d] [-i] [-m NAME] [-r REV] [NAME]
Bookmarks are pointers to certain commits that move when committing.
Bookmarks are local. They can be renamed, copied and deleted. It is
possible to use hg merge NAME to merge from a given bookmark, and hg
update NAME to update to a given bookmark.
You can use hg bookmark NAME to set a bookmark on the working direc‐
tory's parent revision with the given name. If you specify a revision
using -r REV (where REV may be an existing bookmark), the bookmark is
assigned to that revision.
Bookmarks can be pushed and pulled between repositories (see hg help
push and hg help pull). This requires both the local and remote reposi‐
tories to support bookmarks. For versions prior to 1.8, this means the
bookmarks extension must be enabled.
With -i/--inactive, the new bookmark will not be made the active book‐
mark. If -r/--rev is given, the new bookmark will not be made active
even if -i/--inactive is not given. If no NAME is given, the current
active bookmark will be marked inactive.
Options:
-f, --force
force
-r, --rev
revision
-d, --delete
delete a given bookmark
-m, --rename
rename a given bookmark
-i, --inactive
mark a bookmark inactive
branch
hg branch [-fC] [NAME]
Note Branch names are permanent and global. Use hg bookmark to create
a light-weight bookmark instead. See hg help glossary for more
information about named branches and bookmarks.
With no argument, show the current branch name. With one argument, set
the working directory branch name (the branch will not exist in the
repository until the next commit). Standard practice recommends that
primary development take place on the 'default' branch.
Unless -f/--force is specified, branch will not let you set a branch
name that already exists, even if it's inactive.
Use -C/--clean to reset the working directory branch to that of the
parent of the working directory, negating a previous branch change.
Use the command hg update to switch to an existing branch. Use hg com‐
mit --close-branch to mark this branch as closed.
Returns 0 on success.
Options:
-f, --force
set branch name even if it shadows an existing branch
-C, --clean
reset branch name to parent branch name
branches
hg branches [-ac]
List the repository's named branches, indicating which ones are inac‐
tive. If -c/--closed is specified, also list branches which have been
marked closed (see hg commit --close-branch).
If -a/--active is specified, only show active branches. A branch is
considered active if it contains repository heads.
Use the command hg update to switch to an existing branch.
Returns 0.
Options:
-a, --active
show only branches that have unmerged heads
-c, --closed
show normal and closed branches
bundle
hg bundle [-f] [-t TYPE] [-a] [-r REV]... [--base REV]... FILE [DEST]
Generate a compressed changegroup file collecting changesets not known
to be in another repository.
If you omit the destination repository, then hg assumes the destination
will have all the nodes you specify with --base parameters. To create a
bundle containing all changesets, use -a/--all (or --base null).
You can change compression method with the -t/--type option. The
available compression methods are: none, bzip2, and gzip (by default,
bundles are compressed using bzip2).
The bundle file can then be transferred using conventional means and
applied to another repository with the unbundle or pull command. This
is useful when direct push and pull are not available or when exporting
an entire repository is undesirable.
Applying bundles preserves all changeset contents including permis‐
sions, copy/rename information, and revision history.
Returns 0 on success, 1 if no changes found.
Options:
-f, --force
run even when the destination is unrelated
-r, --rev
a changeset intended to be added to the destination
-b, --branch
a specific branch you would like to bundle
--base a base changeset assumed to be available at the destination
-a, --all
bundle all changesets in the repository
-t, --type
bundle compression type to use (default: bzip2)
-e, --ssh
specify ssh command to use
--remotecmd
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
cat
hg cat [OPTION]... FILE...
Print the specified files as they were at the given revision. If no
revision is given, the parent of the working directory is used, or tip
if no revision is checked out.
Output may be to a file, in which case the name of the file is given
using a format string. The formatting rules are the same as for the
export command, with the following additions:
%s
basename of file being printed
%d
dirname of file being printed, or '.' if in repository root
%p
root-relative path name of file being printed
Returns 0 on success.
Options:
-o, --output
print output to file with formatted name
-r, --rev
print the given revision
--decode
apply any matching decode filter
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
clone
hg clone [OPTION]... SOURCE [DEST]
Create a copy of an existing repository in a new directory.
If no destination directory name is specified, it defaults to the base‐
name of the source.
The location of the source is added to the new repository's .hg/hgrc
file, as the default to be used for future pulls.
Only local paths and ssh:// URLs are supported as destinations. For
ssh:// destinations, no working directory or .hg/hgrc will be created
on the remote side.
To pull only a subset of changesets, specify one or more revisions
identifiers with -r/--rev or branches with -b/--branch. The resulting
clone will contain only the specified changesets and their ancestors.
These options (or 'clone src#rev dest') imply --pull, even for local
source repositories. Note that specifying a tag will include the tagged
changeset but not the changeset containing the tag.
To check out a particular version, use -u/--update, or -U/--noupdate to
create a clone with no working directory.
For efficiency, hardlinks are used for cloning whenever the source and
destination are on the same filesystem (note this applies only to the
repository data, not to the working directory). Some filesystems, such
as AFS, implement hardlinking incorrectly, but do not report errors. In
these cases, use the --pull option to avoid hardlinking.
In some cases, you can clone repositories and the working directory
using full hardlinks with
$ cp -al REPO REPOCLONE
This is the fastest way to clone, but it is not always safe. The opera‐
tion is not atomic (making sure REPO is not modified during the opera‐
tion is up to you) and you have to make sure your editor breaks
hardlinks (Emacs and most Linux Kernel tools do so). Also, this is not
compatible with certain extensions that place their metadata under the
.hg directory, such as mq.
Mercurial will update the working directory to the first applicable
revision from this list:
a. null if -U or the source repository has no changesets
b. if -u . and the source repository is local, the first parent of the
source repository's working directory
c. the changeset specified with -u (if a branch name, this means the
latest head of that branch)
d. the changeset specified with -r
e. the tipmost head specified with -b
f. the tipmost head specified with the url#branch source syntax
g. the tipmost head of the default branch
h. tip
Examples:
· clone a remote repository to a new directory named hg/:
hg clone http://selenic.com/hg
· create a lightweight local clone:
hg clone project/ project-feature/
· clone from an absolute path on an ssh server (note double-slash):
hg clone ssh://user@server//home/projects/alpha/
· do a high-speed clone over a LAN while checking out a specified ver‐
sion:
hg clone --uncompressed http://server/repo -u 1.5
· create a repository without changesets after a particular revision:
hg clone -r 04e544 experimental/ good/
· clone (and track) a particular named branch:
hg clone http://selenic.com/hg#stable
See hg help urls for details on specifying URLs.
Returns 0 on success.
Options:
-U, --noupdate
the clone will include an empty working copy (only a repository)
-u, --updaterev
revision, tag or branch to check out
-r, --rev
include the specified changeset
-b, --branch
clone only the specified branch
--pull use pull protocol to copy metadata
--uncompressed
use uncompressed transfer (fast over LAN)
-e, --ssh
specify ssh command to use
--remotecmd
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
commit
hg commit [OPTION]... [FILE]...
Commit changes to the given files into the repository. Unlike a cen‐
tralized SCM, this operation is a local operation. See hg push for a
way to actively distribute your changes.
If a list of files is omitted, all changes reported by hg status will
be committed.
If you are committing the result of a merge, do not provide any file‐
names or -I/-X filters.
If no commit message is specified, Mercurial starts your configured
editor where you can enter a message. In case your commit fails, you
will find a backup of your message in .hg/last-message.txt.
The --amend flag can be used to amend the parent of the working direc‐
tory with a new commit that contains the changes in the parent in addi‐
tion to those currently reported by hg status, if there are any. The
old commit is stored in a backup bundle in .hg/strip-backup (see hg
help bundle and hg help unbundle on how to restore it).
Message, user and date are taken from the amended commit unless speci‐
fied. When a message isn't specified on the command line, the editor
will open with the message of the amended commit.
It is not possible to amend public changesets (see hg help phases) or
changesets that have children.
See hg help dates for a list of formats valid for -d/--date.
Returns 0 on success, 1 if nothing changed.
Options:
-A, --addremove
mark new/missing files as added/removed before committing
--close-branch
mark a branch as closed, hiding it from the branch list
--amend
amend the parent of the working dir
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-m, --message
use text as commit message
-l, --logfile
read commit message from file
-d, --date
record the specified date as commit date
-u, --user
record the specified user as committer
-S, --subrepos
recurse into subrepositories
aliases: ci
copy
hg copy [OPTION]... [SOURCE]... DEST
Mark dest as having copies of source files. If dest is a directory,
copies are put in that directory. If dest is a file, the source must be
a single file.
By default, this command copies the contents of files as they exist in
the working directory. If invoked with -A/--after, the operation is
recorded, but no copying is performed.
This command takes effect with the next commit. To undo a copy before
that, see hg revert.
Returns 0 on success, 1 if errors are encountered.
Options:
-A, --after
record a copy that has already occurred
-f, --force
forcibly copy over an existing managed file
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-n, --dry-run
do not perform actions, just print output
aliases: cp
diff
hg diff [OPTION]... ([-c REV] | [-r REV1 [-r REV2]]) [FILE]...
Show differences between revisions for the specified files.
Differences between files are shown using the unified diff format.
Note diff may generate unexpected results for merges, as it will
default to comparing against the working directory's first par‐
ent changeset if no revisions are specified.
When two revision arguments are given, then changes are shown between
those revisions. If only one revision is specified then that revision
is compared to the working directory, and, when no revisions are speci‐
fied, the working directory files are compared to its parent.
Alternatively you can specify -c/--change with a revision to see the
changes in that changeset relative to its first parent.
Without the -a/--text option, diff will avoid generating diffs of files
it detects as binary. With -a, diff will generate a diff anyway, proba‐
bly with undesirable results.
Use the -g/--git option to generate diffs in the git extended diff for‐
mat. For more information, read hg help diffs.
Examples:
· compare a file in the current working directory to its parent:
hg diff foo.c
· compare two historical versions of a directory, with rename info:
hg diff --git -r 1.0:1.2 lib/
· get change stats relative to the last change on some date:
hg diff --stat -r "date('may 2')"
· diff all newly-added files that contain a keyword:
hg diff "set:added() and grep(GNU)"
· compare a revision and its parents:
hg diff -c 9353 # compare against first parent
hg diff -r 9353^:9353 # same using revset syntax
hg diff -r 9353^2:9353 # compare against the second parent
Returns 0 on success.
Options:
-r, --rev
revision
-c, --change
change made by revision
-a, --text
treat all files as text
-g, --git
use git extended diff format
--nodates
omit dates from diff headers
-p, --show-function
show which function each change is in
--reverse
produce a diff that undoes the changes
-w, --ignore-all-space
ignore white space when comparing lines
-b, --ignore-space-change
ignore changes in the amount of white space
-B, --ignore-blank-lines
ignore changes whose lines are all blank
-U, --unified
number of lines of context to show
--stat output diffstat-style summary of changes
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-S, --subrepos
recurse into subrepositories
export
hg export [OPTION]... [-o OUTFILESPEC] REV...
Print the changeset header and diffs for one or more revisions.
The information shown in the changeset header is: author, date, branch
name (if non-default), changeset hash, parent(s) and commit comment.
Note export may generate unexpected diff output for merge changesets,
as it will compare the merge changeset against its first parent
only.
Output may be to a file, in which case the name of the file is given
using a format string. The formatting rules are as follows:
%%
literal "%" character
%H
changeset hash (40 hexadecimal digits)
%N
number of patches being generated
%R
changeset revision number
%b
basename of the exporting repository
%h
short-form changeset hash (12 hexadecimal digits)
%m
first line of the commit message (only alphanumeric characters)
%n
zero-padded sequence number, starting at 1
%r
zero-padded changeset revision number
Without the -a/--text option, export will avoid generating diffs of
files it detects as binary. With -a, export will generate a diff any‐
way, probably with undesirable results.
Use the -g/--git option to generate diffs in the git extended diff for‐
mat. See hg help diffs for more information.
With the --switch-parent option, the diff will be against the second
parent. It can be useful to review a merge.
Examples:
· use export and import to transplant a bugfix to the current branch:
hg export -r 9353 | hg import -
· export all the changesets between two revisions to a file with rename
information:
hg export --git -r 123:150 > changes.txt
· split outgoing changes into a series of patches with descriptive
names:
hg export -r "outgoing()" -o "%n-%m.patch"
Returns 0 on success.
Options:
-o, --output
print output to file with formatted name
--switch-parent
diff against the second parent
-r, --rev
revisions to export
-a, --text
treat all files as text
-g, --git
use git extended diff format
--nodates
omit dates from diff headers
forget
hg forget [OPTION]... FILE...
Mark the specified files so they will no longer be tracked after the
next commit.
This only removes files from the current branch, not from the entire
project history, and it does not delete them from the working direc‐
tory.
To undo a forget before the next commit, see hg add.
Examples:
· forget newly-added binary files:
hg forget "set:added() and binary()"
· forget files that would be excluded by .hgignore:
hg forget "set:hgignore()"
Returns 0 on success.
Options:
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
graft
hg graft [OPTION]... REVISION...
This command uses Mercurial's merge logic to copy individual changes
from other branches without merging branches in the history graph. This
is sometimes known as 'backporting' or 'cherry-picking'. By default,
graft will copy user, date, and description from the source changesets.
Changesets that are ancestors of the current revision, that have
already been grafted, or that are merges will be skipped.
If a graft merge results in conflicts, the graft process is interrupted
so that the current merge can be manually resolved. Once all conflicts
are addressed, the graft process can be continued with the -c/--con‐
tinue option.
Note The -c/--continue option does not reapply earlier options.
Examples:
· copy a single change to the stable branch and edit its description:
hg update stable
hg graft --edit 9393
· graft a range of changesets with one exception, updating dates:
hg graft -D "2085::2093 and not 2091"
· continue a graft after resolving conflicts:
hg graft -c
· show the source of a grafted changeset:
hg log --debug -r tip
Returns 0 on successful completion.
Options:
-c, --continue
resume interrupted graft
-e, --edit
invoke editor on commit messages
-D, --currentdate
record the current date as commit date
-U, --currentuser
record the current user as committer
-d, --date
record the specified date as commit date
-u, --user
record the specified user as committer
-t, --tool
specify merge tool
-n, --dry-run
do not perform actions, just print output
grep
hg grep [OPTION]... PATTERN [FILE]...
Search revisions of files for a regular expression.
This command behaves differently than Unix grep. It only accepts
Python/Perl regexps. It searches repository history, not the working
directory. It always prints the revision number in which a match
appears.
By default, grep only prints output for the first revision of a file in
which it finds a match. To get it to print every revision that contains
a change in match status ("-" for a match that becomes a non-match, or
"+" for a non-match that becomes a match), use the --all flag.
Returns 0 if a match is found, 1 otherwise.
Options:
-0, --print0
end fields with NUL
--all print all revisions that match
-a, --text
treat all files as text
-f, --follow
follow changeset history, or file history across copies and
renames
-i, --ignore-case
ignore case when matching
-l, --files-with-matches
print only filenames and revisions that match
-n, --line-number
print matching line numbers
-r, --rev
only search files changed within revision range
-u, --user
list the author (long with -v)
-d, --date
list the date (short with -q)
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
heads
hg heads [-ct] [-r STARTREV] [REV]...
With no arguments, show all repository branch heads.
Repository "heads" are changesets with no child changesets. They are
where development generally takes place and are the usual targets for
update and merge operations. Branch heads are changesets that have no
child changeset on the same branch.
If one or more REVs are given, only branch heads on the branches asso‐
ciated with the specified changesets are shown. This means that you can
use hg heads foo to see the heads on a branch named foo.
If -c/--closed is specified, also show branch heads marked closed (see
hg commit --close-branch).
If STARTREV is specified, only those heads that are descendants of
STARTREV will be displayed.
If -t/--topo is specified, named branch mechanics will be ignored and
only changesets without children will be shown.
Returns 0 if matching heads are found, 1 if not.
Options:
-r, --rev
show only heads which are descendants of STARTREV
-t, --topo
show topological heads only
-a, --active
show active branchheads only (DEPRECATED)
-c, --closed
show normal and closed branch heads
--style
display using template map file
--template
display with template
help
hg help [-ec] [TOPIC]
With no arguments, print a list of commands with short help messages.
Given a topic, extension, or command name, print help for that topic.
Returns 0 if successful.
Options:
-e, --extension
show only help for extensions
-c, --command
show only help for commands
identify
hg identify [-nibtB] [-r REV] [SOURCE]
Print a summary identifying the repository state at REV using one or
two parent hash identifiers, followed by a "+" if the working directory
has uncommitted changes, the branch name (if not default), a list of
tags, and a list of bookmarks.
When REV is not given, print a summary of the current state of the
repository.
Specifying a path to a repository root or Mercurial bundle will cause
lookup to operate on that repository/bundle.
Examples:
· generate a build identifier for the working directory:
hg id --id > build-id.dat
· find the revision corresponding to a tag:
hg id -n -r 1.3
· check the most recent revision of a remote repository:
hg id -r tip http://selenic.com/hg/
Returns 0 if successful.
Options:
-r, --rev
identify the specified revision
-n, --num
show local revision number
-i, --id
show global revision id
-b, --branch
show branch
-t, --tags
show tags
-B, --bookmarks
show bookmarks
-e, --ssh
specify ssh command to use
--remotecmd
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
aliases: id
import
hg import [OPTION]... PATCH...
Import a list of patches and commit them individually (unless --no-com‐
mit is specified).
If there are outstanding changes in the working directory, import will
abort unless given the -f/--force flag.
You can import a patch straight from a mail message. Even patches as
attachments work (to use the body part, it must have type text/plain or
text/x-patch). From and Subject headers of email message are used as
default committer and commit message. All text/plain body parts before
first diff are added to commit message.
If the imported patch was generated by hg export, user and description
from patch override values from message headers and body. Values given
on command line with -m/--message and -u/--user override these.
If --exact is specified, import will set the working directory to the
parent of each patch before applying it, and will abort if the result‐
ing changeset has a different ID than the one recorded in the patch.
This may happen due to character set problems or other deficiencies in
the text patch format.
Use --bypass to apply and commit patches directly to the repository,
not touching the working directory. Without --exact, patches will be
applied on top of the working directory parent revision.
With -s/--similarity, hg will attempt to discover renames and copies in
the patch in the same way as hg addremove.
To read a patch from standard input, use "-" as the patch name. If a
URL is specified, the patch will be downloaded from it. See hg help
dates for a list of formats valid for -d/--date.
Examples:
· import a traditional patch from a website and detect renames:
hg import -s 80 http://example.com/bugfix.patch
· import a changeset from an hgweb server:
hg import http://www.selenic.com/hg/rev/5ca8c111e9aa
· import all the patches in an Unix-style mbox:
hg import incoming-patches.mbox
· attempt to exactly restore an exported changeset (not always possi‐
ble):
hg import --exact proposed-fix.patch
Returns 0 on success.
Options:
-p, --strip
directory strip option for patch. This has the same meaning as
the corresponding patch option (default: 1)
-b, --base
base path (DEPRECATED)
-e, --edit
invoke editor on commit messages
-f, --force
skip check for outstanding uncommitted changes
--no-commit
don't commit, just update the working directory
--bypass
apply patch without touching the working directory
--exact
apply patch to the nodes from which it was generated
--import-branch
use any branch information in patch (implied by --exact)
-m, --message
use text as commit message
-l, --logfile
read commit message from file
-d, --date
record the specified date as commit date
-u, --user
record the specified user as committer
-s, --similarity
guess renamed files by similarity (0<=s<=100)
aliases: patch
incoming
hg incoming [-p] [-n] [-M] [-f] [-r REV]... [--bundle FILENAME] [SOURCE]
Show new changesets found in the specified path/URL or the default pull
location. These are the changesets that would have been pulled if a
pull at the time you issued this command.
For remote repository, using --bundle avoids downloading the changesets
twice if the incoming is followed by a pull.
See pull for valid source format details.
Returns 0 if there are incoming changes, 1 otherwise.
Options:
-f, --force
run even if remote repository is unrelated
-n, --newest-first
show newest record first
--bundle
file to store the bundles into
-r, --rev
a remote changeset intended to be added
-B, --bookmarks
compare bookmarks
-b, --branch
a specific branch you would like to pull
-p, --patch
show patch
-g, --git
use git extended diff format
-l, --limit
limit number of changes displayed
-M, --no-merges
do not show merges
--stat output diffstat-style summary of changes
--style
display using template map file
--template
display with template
-e, --ssh
specify ssh command to use
--remotecmd
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
-S, --subrepos
recurse into subrepositories
aliases: in
init
hg init [-e CMD] [--remotecmd CMD] [DEST]
Initialize a new repository in the given directory. If the given direc‐
tory does not exist, it will be created.
If no directory is given, the current directory is used.
It is possible to specify an ssh:// URL as the destination. See hg
help urls for more information.
Returns 0 on success.
Options:
-e, --ssh
specify ssh command to use
--remotecmd
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
locate
hg locate [OPTION]... [PATTERN]...
Print files under Mercurial control in the working directory whose
names match the given patterns.
By default, this command searches all directories in the working direc‐
tory. To search just the current directory and its subdirectories, use
"--include .".
If no patterns are given to match, this command prints the names of all
files under Mercurial control in the working directory.
If you want to feed the output of this command into the "xargs" com‐
mand, use the -0 option to both this command and "xargs". This will
avoid the problem of "xargs" treating single filenames that contain
whitespace as multiple filenames.
Returns 0 if a match is found, 1 otherwise.
Options:
-r, --rev
search the repository as it is in REV
-0, --print0
end filenames with NUL, for use with xargs
-f, --fullpath
print complete paths from the filesystem root
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
log
hg log [OPTION]... [FILE]
Print the revision history of the specified files or the entire
project.
If no revision range is specified, the default is tip:0 unless --follow
is set, in which case the working directory parent is used as the
starting revision.
File history is shown without following rename or copy history of
files. Use -f/--follow with a filename to follow history across renames
and copies. --follow without a filename will only show ancestors or
descendants of the starting revision.
By default this command prints revision number and changeset id, tags,
non-trivial parents, user, date and time, and a summary for each com‐
mit. When the -v/--verbose switch is used, the list of changed files
and full commit message are shown.
Note log -p/--patch may generate unexpected diff output for merge
changesets, as it will only compare the merge changeset against
its first parent. Also, only files different from BOTH parents
will appear in files:.
Note for performance reasons, log FILE may omit duplicate changes
made on branches and will not show deletions. To see all changes
including duplicates and deletions, use the --removed switch.
Some examples:
· changesets with full descriptions and file lists:
hg log -v
· changesets ancestral to the working directory:
hg log -f
· last 10 commits on the current branch:
hg log -l 10 -b .
· changesets showing all modifications of a file, including removals:
hg log --removed file.c
· all changesets that touch a directory, with diffs, excluding merges:
hg log -Mp lib/
· all revision numbers that match a keyword:
hg log -k bug --template "{rev}\n"
· check if a given changeset is included is a tagged release:
hg log -r "a21ccf and ancestor(1.9)"
· find all changesets by some user in a date range:
hg log -k alice -d "may 2008 to jul 2008"
· summary of all changesets after the last tag:
hg log -r "last(tagged())::" --template "{desc|firstline}\n"
See hg help dates for a list of formats valid for -d/--date.
See hg help revisions and hg help revsets for more about specifying
revisions.
See hg help templates for more about pre-packaged styles and specifying
custom templates.
Returns 0 on success.
Options:
-f, --follow

aliases: history
manifest
hg manifest [-r REV]
Print a list of version controlled files for the given revision. If no
revision is given, the first parent of the working directory is used,
or the null revision if no revision is checked out.
With -v, print file permissions, symlink and executable bits. With
--debug, print file revision hashes.
If option --all is specified, the list of all files from all revisions
is printed. This includes deleted and renamed files.
Returns 0 on success.
Options:
-r, --rev
revision to display
--all list files from all revisions
merge
hg merge [-P] [-f] [[-r] REV]
The current working directory is updated with all changes made in the
requested revision since the last common predecessor revision.
Files that changed between either parent are marked as changed for the
next commit and a commit must be performed before any further updates
to the repository are allowed. The next commit will have two parents.
--tool can be used to specify the merge tool used for file merges. It
overrides the HGMERGE environment variable and your configuration
files. See hg help merge-tools for options.
If no revision is specified, the working directory's parent is a head
revision, and the current branch contains exactly one other head, the
other head is merged with by default. Otherwise, an explicit revision
with which to merge with must be provided.
hg resolve must be used to resolve unresolved files.
To undo an uncommitted merge, use hg update --clean . which will check
out a clean copy of the original merge parent, losing all changes.
Returns 0 on success, 1 if there are unresolved files.
Options:
-f, --force
force a merge with outstanding changes
-r, --rev
revision to merge
-P, --preview
review revisions to merge (no merge is performed)
-t, --tool
specify merge tool
outgoing
hg outgoing [-M] [-p] [-n] [-f] [-r REV]... [DEST]
Show changesets not found in the specified destination repository or
the default push location. These are the changesets that would be
pushed if a push was requested.
See pull for details of valid destination formats.
Returns 0 if there are outgoing changes, 1 otherwise.
Options:
-f, --force
run even when the destination is unrelated
-r, --rev
a changeset intended to be included in the destination
-n, --newest-first
show newest record first
-B, --bookmarks
compare bookmarks
-b, --branch
a specific branch you would like to push
-p, --patch
show patch
-g, --git
use git extended diff format
-l, --limit
limit number of changes displayed
-M, --no-merges
do not show merges
--stat output diffstat-style summary of changes
--style
display using template map file
--template
display with template
-e, --ssh
specify ssh command to use
--remotecmd
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
-S, --subrepos
recurse into subrepositories
aliases: out
parents
hg parents [-r REV] [FILE]
Print the working directory's parent revisions. If a revision is given
via -r/--rev, the parent of that revision will be printed. If a file
argument is given, the revision in which the file was last changed
(before the working directory revision or the argument to --rev if
given) is printed.
Returns 0 on success.
Options:
-r, --rev
show parents of the specified revision
--style
display using template map file
--template
display with template
paths
hg paths [NAME]
Show definition of symbolic path name NAME. If no name is given, show
definition of all available names.
Option -q/--quiet suppresses all output when searching for NAME and
shows only the path names when listing all definitions.
Path names are defined in the [paths] section of your configuration
file and in /etc/mercurial/hgrc. If run inside a repository, .hg/hgrc
is used, too.
The path names default and default-push have a special meaning. When
performing a push or pull operation, they are used as fallbacks if no
location is specified on the command-line. When default-push is set,
it will be used for push and default will be used for pull; otherwise
default is used as the fallback for both. When cloning a repository,
the clone source is written as default in .hg/hgrc. Note that default
and default-push apply to all inbound (e.g. hg incoming) and outbound
(e.g. hg outgoing, hg email and hg bundle) operations.
See hg help urls for more information.
Returns 0 on success.
phase
hg phase [-p|-d|-s] [-f] [-r] REV...
With no argument, show the phase name of specified revisions.
With one of -p/--public, -d/--draft or -s/--secret, change the phase
value of the specified revisions.
Unless -f/--force is specified, hg phase won't move changeset from a
lower phase to an higher phase. Phases are ordered as follows:
public < draft < secret
Return 0 on success, 1 if no phases were changed or some could not be
changed.
Options:
-p, --public
set changeset phase to public
-d, --draft
set changeset phase to draft
-s, --secret
set changeset phase to secret
-f, --force
allow to move boundary backward
-r, --rev
target revision
pull
hg pull [-u] [-f] [-r REV]... [-e CMD] [--remotecmd CMD] [SOURCE]
Pull changes from a remote repository to a local one.
This finds all changes from the repository at the specified path or URL
and adds them to a local repository (the current one unless -R is spec‐
ified). By default, this does not update the copy of the project in the
working directory.
Use hg incoming if you want to see what would have been added by a pull
at the time you issued this command. If you then decide to add those
changes to the repository, you should use hg pull -r X where X is the
last changeset listed by hg incoming.
If SOURCE is omitted, the 'default' path will be used. See hg help
urls for more information.
Returns 0 on success, 1 if an update had unresolved files.
Options:
-u, --update
update to new branch head if changesets were pulled
-f, --force
run even when remote repository is unrelated
-r, --rev
a remote changeset intended to be added
-B, --bookmark
bookmark to pull
-b, --branch
a specific branch you would like to pull
-e, --ssh
specify ssh command to use
--remotecmd
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
push
hg push [-f] [-r REV]... [-e CMD] [--remotecmd CMD] [DEST]
Push changesets from the local repository to the specified destination.
This operation is symmetrical to pull: it is identical to a pull in the
destination repository from the current one.
By default, push will not allow creation of new heads at the destina‐
tion, since multiple heads would make it unclear which head to use. In
this situation, it is recommended to pull and merge before pushing.
Use --new-branch if you want to allow push to create a new named branch
that is not present at the destination. This allows you to only create
a new branch without forcing other changes.
Use -f/--force to override the default behavior and push all changesets
on all branches.
If -r/--rev is used, the specified revision and all its ancestors will
be pushed to the remote repository.
Please see hg help urls for important details about ssh:// URLs. If
DESTINATION is omitted, a default path will be used.
Returns 0 if push was successful, 1 if nothing to push.
Options:
-f, --force
force push
-r, --rev
a changeset intended to be included in the destination
-B, --bookmark
bookmark to push
-b, --branch
a specific branch you would like to push
--new-branch
allow pushing a new branch
-e, --ssh
specify ssh command to use
--remotecmd
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
recover
hg recover
Recover from an interrupted commit or pull.
This command tries to fix the repository status after an interrupted
operation. It should only be necessary when Mercurial suggests it.
Returns 0 if successful, 1 if nothing to recover or verify fails.
remove
hg remove [OPTION]... FILE...
Schedule the indicated files for removal from the current branch.
This command schedules the files to be removed at the next commit. To
undo a remove before that, see hg revert. To undo added files, see hg
forget.
-A/--after can be used to remove only files that have already been
deleted, -f/--force can be used to force deletion, and -Af can be used
to remove files from the next revision without deleting them from the
working directory.
The following table details the behavior of remove for different file
states (columns) and option combinations (rows). The file states are
Added [A], Clean [C], Modified [M] and Missing [!] (as reported by hg
status). The actions are Warn, Remove (from branch) and Delete (from
disk):
┌─────┬───┬────┬────┬───┐
│ │ │ │ │ │
├─────┼───┼────┼────┼───┤
│none │ W │ RD │ W │ R │
├─────┼───┼────┼────┼───┤
│-f │ R │ RD │ RD │ R │
├─────┼───┼────┼────┼───┤
│-A │ W │ W │ W │ R │
└─────┴───┴────┴────┴───┘
│-Af │ R │ R │ R │ R │
└─────┴───┴────┴────┴───┘
Note that remove never deletes files in Added [A] state from the work‐
ing directory, not even if option --force is specified.
Returns 0 on success, 1 if any warnings encountered.
Options:
-A, --after
record delete for missing files
-f, --force
remove (and delete) file even if added or modified
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
aliases: rm
rename
hg rename [OPTION]... SOURCE... DEST
Mark dest as copies of sources; mark sources for deletion. If dest is a
directory, copies are put in that directory. If dest is a file, there
can only be one source.
By default, this command copies the contents of files as they exist in
the working directory. If invoked with -A/--after, the operation is
recorded, but no copying is performed.
This command takes effect at the next commit. To undo a rename before
that, see hg revert.
Returns 0 on success, 1 if errors are encountered.
Options:
-A, --after
record a rename that has already occurred
-f, --force
forcibly copy over an existing managed file
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-n, --dry-run
do not perform actions, just print output
aliases: move mv
resolve
hg resolve [OPTION]... [FILE]...
Merges with unresolved conflicts are often the result of non-interac‐
tive merging using the internal:merge configuration setting, or a com‐
mand-line merge tool like diff3. The resolve command is used to manage
the files involved in a merge, after hg merge has been run, and before
hg commit is run (i.e. the working directory must have two parents).
See hg help merge-tools for information on configuring merge tools.
The resolve command can be used in the following ways:
· hg resolve [--tool TOOL] FILE...: attempt to re-merge the specified
files, discarding any previous merge attempts. Re-merging is not per‐
formed for files already marked as resolved. Use --all/-a to select
all unresolved files. --tool can be used to specify the merge tool
used for the given files. It overrides the HGMERGE environment vari‐
able and your configuration files. Previous file contents are saved
with a .orig suffix.
· hg resolve -m [FILE]: mark a file as having been resolved (e.g. after
having manually fixed-up the files). The default is to mark all unre‐
solved files.
· hg resolve -u [FILE]...: mark a file as unresolved. The default is to
mark all resolved files.
· hg resolve -l: list files which had or still have conflicts. In the
printed list, U = unresolved and R = resolved.
Note that Mercurial will not let you commit files with unresolved merge
conflicts. You must use hg resolve -m ... before you can commit after a
conflicting merge.
Returns 0 on success, 1 if any files fail a resolve attempt.
Options:
-a, --all
select all unresolved files
-l, --list
list state of files needing merge
-m, --mark
mark files as resolved
-u, --unmark
mark files as unresolved
-n, --no-status
hide status prefix
-t, --tool
specify merge tool
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
revert
hg revert [OPTION]... [-r REV] [NAME]...
Note To check out earlier revisions, you should use hg update REV.
To cancel a merge (and lose your changes), use hg update --clean
..
With no revision specified, revert the specified files or directories
to the contents they had in the parent of the working directory. This
restores the contents of files to an unmodified state and unschedules
adds, removes, copies, and renames. If the working directory has two
parents, you must explicitly specify a revision.
Using the -r/--rev or -d/--date options, revert the given files or
directories to their states as of a specific revision. Because revert
does not change the working directory parents, this will cause these
files to appear modified. This can be helpful to "back out" some or all
of an earlier change. See hg backout for a related method.
Modified files are saved with a .orig suffix before reverting. To dis‐
able these backups, use --no-backup.
See hg help dates for a list of formats valid for -d/--date.
Returns 0 on success.
Options:
-a, --all
revert all changes when no arguments given
-d, --date
tipmost revision matching date
-r, --rev
revert to the specified revision
-C, --no-backup
do not save backup copies of files
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-n, --dry-run
do not perform actions, just print output
rollback
hg rollback
This command should be used with care. There is only one level of roll‐
back, and there is no way to undo a rollback. It will also restore the
dirstate at the time of the last transaction, losing any dirstate
changes since that time. This command does not alter the working direc‐
tory.
Transactions are used to encapsulate the effects of all commands that
create new changesets or propagate existing changesets into a reposi‐
tory. For example, the following commands are transactional, and their
effects can be rolled back:
· commit
· import
· pull
· push (with this repository as the destination)
· unbundle
To avoid permanent data loss, rollback will refuse to rollback a commit
transaction if it isn't checked out. Use --force to override this pro‐
tection.
This command is not intended for use on public repositories. Once
changes are visible for pull by other users, rolling a transaction back
locally is ineffective (someone else may already have pulled the
changes). Furthermore, a race is possible with readers of the reposi‐
tory; for example an in-progress pull from the repository may fail if a
rollback is performed.
Returns 0 on success, 1 if no rollback data is available.
Options:
-n, --dry-run
do not perform actions, just print output
-f, --force
ignore safety measures
root
hg root
Print the root directory of the current repository.
Returns 0 on success.
serve
hg serve [OPTION]...
Start a local HTTP repository browser and pull server. You can use this
for ad-hoc sharing and browsing of repositories. It is recommended to
use a real web server to serve a repository for longer periods of time.
Please note that the server does not implement access control. This
means that, by default, anybody can read from the server and nobody can
write to it by default. Set the web.allow_push option to * to allow
everybody to push to the server. You should use a real web server if
you need to authenticate users.
By default, the server logs accesses to stdout and errors to stderr.
Use the -A/--accesslog and -E/--errorlog options to log to files.
To have the server choose a free port number to listen on, specify a
port number of 0; in this case, the server will print the port number
it uses.
Returns 0 on success.
Options:
-A, --accesslog
name of access log file to write to
-d, --daemon
run server in background
--daemon-pipefds
used internally by daemon mode
-E, --errorlog
name of error log file to write to
-p, --port
port to listen on (default: 8000)
-a, --address
address to listen on (default: all interfaces)
--prefix
prefix path to serve from (default: server root)
-n, --name
name to show in web pages (default: working directory)
--web-conf
name of the hgweb config file (see "hg help hgweb")
--webdir-conf
name of the hgweb config file (DEPRECATED)
--pid-file
name of file to write process ID to
--stdio
for remote clients
--cmdserver
for remote clients
-t, --templates
web templates to use
--style
template style to use
-6, --ipv6
use IPv6 in addition to IPv4
--certificate
SSL certificate file
showconfig
hg showconfig [-u] [NAME]...
With no arguments, print names and values of all config items.
With one argument of the form section.name, print just the value of
that config item.
With multiple arguments, print names and values of all config items
with matching section names.
With --debug, the source (filename and line number) is printed for each
config item.
Returns 0 on success.
Options:
-u, --untrusted
show untrusted configuration options
aliases: debugconfig
status
hg status [OPTION]... [FILE]...
Show status of files in the repository. If names are given, only files
that match are shown. Files that are clean or ignored or the source of
a copy/move operation, are not listed unless -c/--clean, -i/--ignored,
-C/--copies or -A/--all are given. Unless options described with "show
only ..." are given, the options -mardu are used.
Option -q/--quiet hides untracked (unknown and ignored) files unless
explicitly requested with -u/--unknown or -i/--ignored.
Note status may appear to disagree with diff if permissions have
changed or a merge has occurred. The standard diff format does
not report permission changes and diff only reports changes rel‐
ative to one merge parent.
If one revision is given, it is used as the base revision. If two
revisions are given, the differences between them are shown. The
--change option can also be used as a shortcut to list the changed
files of a revision from its first parent.
The codes used to show the status of files are:
M = modified
A = added
R = removed
C = clean
! = missing (deleted by non-hg command, but still tracked)
? = not tracked
I = ignored
= origin of the previous file listed as A (added)
Examples:
· show changes in the working directory relative to a changeset:
hg status --rev 9353
· show all changes including copies in an existing changeset:
hg status --copies --change 9353
· get a NUL separated list of added files, suitable for xargs:
hg status -an0
Returns 0 on success.
Options:
-A, --all
show status of all files
-m, --modified
show only modified files
-a, --added
show only added files
-r, --removed
show only removed files
-d, --deleted
show only deleted (but tracked) files
-c, --clean
show only files without changes
-u, --unknown
show only unknown (not tracked) files
-i, --ignored
show only ignored files
-n, --no-status
hide status prefix
-C, --copies
show source of copied files
-0, --print0
end filenames with NUL, for use with xargs
--rev show difference from revision
--change
list the changed files of a revision
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-S, --subrepos
recurse into subrepositories
aliases: st
summary
hg summary [--remote]
This generates a brief summary of the working directory state, includ‐
ing parents, branch, commit status, and available updates.
With the --remote option, this will check the default paths for incom‐
ing and outgoing changes. This can be time-consuming.
Returns 0 on success.
Options:
--remote
check for push and pull
aliases: sum
tag
hg tag [-f] [-l] [-m TEXT] [-d DATE] [-u USER] [-r REV] NAME...
Name a particular revision using <name>.
Tags are used to name particular revisions of the repository and are
very useful to compare different revisions, to go back to significant
earlier versions or to mark branch points as releases, etc. Changing an
existing tag is normally disallowed; use -f/--force to override.
If no revision is given, the parent of the working directory is used,
or tip if no revision is checked out.
To facilitate version control, distribution, and merging of tags, they
are stored as a file named ".hgtags" which is managed similarly to
other project files and can be hand-edited if necessary. This also
means that tagging creates a new commit. The file ".hg/localtags" is
used for local tags (not shared among repositories).
Tag commits are usually made at the head of a branch. If the parent of
the working directory is not a branch head, hg tag aborts; use
-f/--force to force the tag commit to be based on a non-head changeset.
See hg help dates for a list of formats valid for -d/--date.
Since tag names have priority over branch names during revision lookup,
using an existing branch name as a tag name is discouraged.
Returns 0 on success.
Options:
-f, --force
force tag
-l, --local
make the tag local
-r, --rev
revision to tag
--remove
remove a tag
-e, --edit
edit commit message
-m, --message
use <text> as commit message
-d, --date
record the specified date as commit date
-u, --user
record the specified user as committer
tags
hg tags
This lists both regular and local tags. When the -v/--verbose switch is
used, a third column "local" is printed for local tags.
Returns 0 on success.
tip
hg tip [-p] [-g]
The tip revision (usually just called the tip) is the changeset most
recently added to the repository (and therefore the most recently
changed head).
If you have just made a commit, that commit will be the tip. If you
have just pulled changes from another repository, the tip of that
repository becomes the current tip. The "tip" tag is special and cannot
be renamed or assigned to a different changeset.
Returns 0 on success.
Options:
-p, --patch
show patch
-g, --git
use git extended diff format
--style
display using template map file
--template
display with template
unbundle
hg unbundle [-u] FILE...
Apply one or more compressed changegroup files generated by the bundle
command.
Returns 0 on success, 1 if an update has unresolved files.
Options:
-u, --update
update to new branch head if changesets were unbundled
update
hg update [-c] [-C] [-d DATE] [[-r] REV]
Update the repository's working directory to the specified changeset.
If no changeset is specified, update to the tip of the current named
branch and move the current bookmark (see hg help bookmarks).
If the changeset is not a descendant or ancestor of the working direc‐
tory's parent, the update is aborted. With the -c/--check option, the
working directory is checked for uncommitted changes; if none are
found, the working directory is updated to the specified changeset.
Update sets the working directory's parent revison to the specified
changeset (see hg help parents).
The following rules apply when the working directory contains uncommit‐
ted changes:
1. If neither -c/--check nor -C/--clean is specified, and if the
requested changeset is an ancestor or descendant of the working
directory's parent, the uncommitted changes are merged into the
requested changeset and the merged result is left uncommitted. If
the requested changeset is not an ancestor or descendant (that is,
it is on another branch), the update is aborted and the uncommitted
changes are preserved.
2. With the -c/--check option, the update is aborted and the uncommit‐
ted changes are preserved.
3. With the -C/--clean option, uncommitted changes are discarded and
the working directory is updated to the requested changeset.
Use null as the changeset to remove the working directory (like hg
clone -U).
If you want to revert just one file to an older revision, use hg revert
[-r REV] NAME.
See hg help dates for a list of formats valid for -d/--date.
Returns 0 on success, 1 if there are unresolved files.
Options:
-C, --clean
discard uncommitted changes (no backup)
-c, --check
update across branches if no uncommitted changes
-d, --date
tipmost revision matching date
-r, --rev
revision
aliases: up checkout co
verify
hg verify
Verify the integrity of the current repository.
This will perform an extensive check of the repository's integrity,
validating the hashes and checksums of each entry in the changelog,
manifest, and tracked files, as well as the integrity of their
crosslinks and indices.
Returns 0 on success, 1 if errors are encountered.
version
hg version
output version and copyright information
DATE FORMATS
Some commands allow the user to specify a date, e.g.:
· backout, commit, import, tag: Specify the commit date.
· log, revert, update: Select revision(s) by date.
Many date formats are valid. Here are some examples:
· Wed Dec 6 13:18:29 2006 (local timezone assumed)
· Dec 6 13:18 -0600 (year assumed, time offset provided)
· Dec 6 13:18 UTC (UTC and GMT are aliases for +0000)
· Dec 6 (midnight)
· 13:18 (today assumed)
· 3:39 (3:39AM assumed)
· 3:39pm (15:39)
· 2006-12-06 13:18:29 (ISO 8601 format)
· 2006-12-6 13:18
· 2006-12-6
· 12-6
· 12/6
· 12/6/6 (Dec 6 2006)
Lastly, there is Mercurial's internal format:
· 1165432709 0 (Wed Dec 6 13:18:29 2006 UTC)
This is the internal representation format for dates. The first number
is the number of seconds since the epoch (1970-01-01 00:00 UTC). The
second is the offset of the local timezone, in seconds west of UTC
(negative if the timezone is east of UTC).
The log command also accepts date ranges:
· <DATE - at or before a given date/time
· >DATE - on or after a given date/time
· DATE to DATE - a date range, inclusive
· -DAYS - within a given number of days of today
DIFF FORMATS
Mercurial's default format for showing changes between two versions of
a file is compatible with the unified format of GNU diff, which can be
used by GNU patch and many other standard tools.
While this standard format is often enough, it does not encode the fol‐
lowing information:
· executable status and other permission bits
· copy or rename information
· changes in binary files
· creation or deletion of empty files
Mercurial also supports the extended diff format from the git VCS which
addresses these limitations. The git diff format is not produced by
default because a few widespread tools still do not understand this
format.
This means that when generating diffs from a Mercurial repository (e.g.
with hg export), you should be careful about things like file copies
and renames or other things mentioned above, because when applying a
standard diff to a different repository, this extra information is
lost. Mercurial's internal operations (like push and pull) are not
affected by this, because they use an internal binary format for commu‐
nicating changes.
To make Mercurial produce the git extended diff format, use the --git
option available for many commands, or set 'git = True' in the [diff]
section of your configuration file. You do not need to set this option
when importing diffs in this format or using them in the mq extension.
ENVIRONMENT VARIABLESHG Path to the 'hg' executable, automatically passed when running
hooks, extensions or external tools. If unset or empty, this is
the hg executable's name if it's frozen, or an executable named
'hg' (with %PATHEXT% [defaulting to COM/EXE/BAT/CMD] extensions
on Windows) is searched.
HGEDITOR
This is the name of the editor to run when committing. See EDI‐
TOR.
(deprecated, use configuration file)
HGENCODING
This overrides the default locale setting detected by Mercurial.
This setting is used to convert data including usernames,
changeset descriptions, tag names, and branches. This setting
can be overridden with the --encoding command-line option.
HGENCODINGMODE
This sets Mercurial's behavior for handling unknown characters
while transcoding user input. The default is "strict", which
causes Mercurial to abort if it can't map a character. Other
settings include "replace", which replaces unknown characters,
and "ignore", which drops them. This setting can be overridden
with the --encodingmode command-line option.
HGENCODINGAMBIGUOUS
This sets Mercurial's behavior for handling characters with
"ambiguous" widths like accented Latin characters with East
Asian fonts. By default, Mercurial assumes ambiguous characters
are narrow, set this variable to "wide" if such characters cause
formatting problems.
HGMERGE
An executable to use for resolving merge conflicts. The program
will be executed with three arguments: local file, remote file,
ancestor file.
(deprecated, use configuration file)
HGRCPATH
A list of files or directories to search for configuration
files. Item separator is ":" on Unix, ";" on Windows. If HGRC‐
PATH is not set, platform default search path is used. If empty,
only the .hg/hgrc from the current repository is read.
For each element in HGRCPATH:
· if it's a directory, all files ending with .rc are added
· otherwise, the file itself will be added
HGPLAIN
When set, this disables any configuration settings that might
change Mercurial's default output. This includes encoding,
defaults, verbose mode, debug mode, quiet mode, tracebacks, and
localization. This can be useful when scripting against Mercu‐
rial in the face of existing user configuration.
Equivalent options set via command line flags or environment
variables are not overridden.
HGPLAINEXCEPT
This is a comma-separated list of features to preserve when
HGPLAIN is enabled. Currently the only value supported is
"i18n", which preserves internationalization in plain mode.
Setting HGPLAINEXCEPT to anything (even an empty string) will
enable plain mode.
HGUSER This is the string used as the author of a commit. If not set,
available values will be considered in this order:
· HGUSER (deprecated)
· configuration files from the HGRCPATH
· EMAIL
· interactive prompt
· LOGNAME (with @hostname appended)
(deprecated, use configuration file)
EMAIL May be used as the author of a commit; see HGUSER.
LOGNAME
May be used as the author of a commit; see HGUSER.
VISUAL This is the name of the editor to use when committing. See EDI‐
TOR.
EDITOR Sometimes Mercurial needs to open a text file in an editor for a
user to modify, for example when writing commit messages. The
editor it uses is determined by looking at the environment vari‐
ables HGEDITOR, VISUAL and EDITOR, in that order. The first
non-empty one is chosen. If all of them are empty, the editor
defaults to 'vi'.
PYTHONPATH
This is used by Python to find imported modules and may need to
be set appropriately if this Mercurial is not installed sys‐
tem-wide.
USING ADDITIONAL FEATURES
Mercurial has the ability to add new features through the use of exten‐
sions. Extensions may add new commands, add options to existing com‐
mands, change the default behavior of commands, or implement hooks.
Extensions are not loaded by default for a variety of reasons: they can
increase startup overhead; they may be meant for advanced usage only;
they may provide potentially dangerous abilities (such as letting you
destroy or modify history); they might not be ready for prime time; or
they may alter some usual behaviors of stock Mercurial. It is thus up
to the user to activate extensions as needed.
To enable the "foo" extension, either shipped with Mercurial or in the
Python search path, create an entry for it in your configuration file,
like this:
[extensions]
foo =
You may also specify the full path to an extension:
[extensions]
myfeature = ~/.hgext/myfeature.py
To explicitly disable an extension enabled in a configuration file of
broader scope, prepend its path with !:
[extensions]
# disabling extension bar residing in /path/to/extension/bar.py
bar = !/path/to/extension/bar.py
# ditto, but no path was supplied for extension baz
baz = !

SPECIFYING FILE SETS
Mercurial supports a functional language for selecting a set of files.
Like other file patterns, this pattern type is indicated by a prefix,
'set:'. The language supports a number of predicates which are joined
by infix operators. Parenthesis can be used for grouping.
Identifiers such as filenames or patterns must be quoted with single or
double quotes if they contain characters outside of
[.*{}[]?/\_a-zA-Z0-9\x80-\xff] or if they match one of the predefined
predicates. This generally applies to file patterns other than globs
and arguments for predicates.
Special characters can be used in quoted identifiers by escaping them,
e.g., \n is interpreted as a newline. To prevent them from being inter‐
preted, strings can be prefixed with r, e.g. r'...'.
There is a single prefix operator:
not x
Files not in x. Short form is ! x.
These are the supported infix operators:
x and y
The intersection of files in x and y. Short form is x & y.
x or y
The union of files in x and y. There are two alternative short
forms: x | y and x + y.
x - y
Files in x but not in y.
The following predicates are supported:
added()
File that is added according to status.
binary()
File that appears to be binary (contains NUL bytes).
clean()
File that is clean according to status.
copied()
File that is recorded as being copied.
deleted()
File that is deleted according to status.
encoding(name)
File can be successfully decoded with the given character encod‐
ing. May not be useful for encodings other than ASCII and UTF-8.
exec()
File that is marked as executable.
grep(regex)
File contains the given regular expression.
hgignore()
File that matches the active .hgignore pattern.
ignored()
File that is ignored according to status. These files will only
be considered if this predicate is used.
modified()
File that is modified according to status.
removed()
File that is removed according to status.
resolved()
File that is marked resolved according to the resolve state.
size(expression)
File size matches the given expression. Examples:
· 1k (files from 1024 to 2047 bytes)
· < 20k (files less than 20480 bytes)
· >= .5MB (files at least 524288 bytes)
· 4k - 1MB (files from 4096 bytes to 1048576 bytes)
subrepo([pattern])
Subrepositories whose paths match the given pattern.
symlink()
File that is marked as a symlink.
unknown()
File that is unknown according to status. These files will only
be considered if this predicate is used.
unresolved()
File that is marked unresolved according to the resolve state.
Some sample queries:
· Show status of files that appear to be binary in the working direc‐
tory:
hg status -A "set:binary()"
· Forget files that are in .hgignore but are already tracked:
hg forget "set:hgignore() and not ignored()"
· Find text files that contain a string:
hg locate "set:grep(magic) and not binary()"
· Find C files in a non-standard encoding:
hg locate "set:**.c and not encoding('UTF-8')"
· Revert copies of large binary files:
hg revert "set:copied() and binary() and size('>1M')"
· Remove files listed in foo.lst that contain the letter a or b:
hg remove "set: 'listfile:foo.lst' and (**a* or **b*)"
See also hg help patterns.
GLOSSARY
Ancestor
Any changeset that can be reached by an unbroken chain of parent
changesets from a given changeset. More precisely, the ancestors
of a changeset can be defined by two properties: a parent of a
changeset is an ancestor, and a parent of an ancestor is an
ancestor. See also: 'Descendant'.
Bookmark
Bookmarks are pointers to certain commits that move when commit‐
ting. They are similar to tags in that it is possible to use
bookmark names in all places where Mercurial expects a changeset
ID, e.g., with hg update. Unlike tags, bookmarks move along when
you make a commit.
Bookmarks can be renamed, copied and deleted. Bookmarks are
local, unless they are explicitly pushed or pulled between
repositories. Pushing and pulling bookmarks allow you to col‐
laborate with others on a branch without creating a named
branch.
Branch (Noun) A child changeset that has been created from a parent
that is not a head. These are known as topological branches, see
'Branch, topological'. If a topological branch is named, it
becomes a named branch. If a topological branch is not named, it
becomes an anonymous branch. See 'Branch, anonymous' and
'Branch, named'.
Branches may be created when changes are pulled from or pushed
to a remote repository, since new heads may be created by these
operations. Note that the term branch can also be used infor‐
mally to describe a development process in which certain devel‐
opment is done independently of other development. This is some‐
times done explicitly with a named branch, but it can also be
done locally, using bookmarks or clones and anonymous branches.
Example: "The experimental branch".
(Verb) The action of creating a child changeset which results in
its parent having more than one child.
Example: "I'm going to branch at X".
Branch, anonymous
Every time a new child changeset is created from a parent that
is not a head and the name of the branch is not changed, a new
anonymous branch is created.
Branch, closed
A named branch whose branch heads have all been closed.
Branch, default
The branch assigned to a changeset when no name has previously
been assigned.
Branch head
See 'Head, branch'.
Branch, inactive
If a named branch has no topological heads, it is considered to
be inactive. As an example, a feature branch becomes inactive
when it is merged into the default branch. The hg branches com‐
mand shows inactive branches by default, though they can be hid‐
den with hg branches --active.
NOTE: this concept is deprecated because it is too implicit.
Branches should now be explicitly closed using hg commit
--close-branch when they are no longer needed.
Branch, named
A collection of changesets which have the same branch name. By
default, children of a changeset in a named branch belong to the
same named branch. A child can be explicitly assigned to a dif‐
ferent branch. See hg help branch, hg help branches and hg com‐
mit --close-branch for more information on managing branches.
Named branches can be thought of as a kind of namespace, divid‐
ing the collection of changesets that comprise the repository
into a collection of disjoint subsets. A named branch is not
necessarily a topological branch. If a new named branch is cre‐
ated from the head of another named branch, or the default
branch, but no further changesets are added to that previous
branch, then that previous branch will be a branch in name only.
Branch tip
See 'Tip, branch'.
Branch, topological
Every time a new child changeset is created from a parent that
is not a head, a new topological branch is created. If a topo‐
logical branch is named, it becomes a named branch. If a topo‐
logical branch is not named, it becomes an anonymous branch of
the current, possibly default, branch.
Changelog
A record of the changesets in the order in which they were added
to the repository. This includes details such as changeset id,
author, commit message, date, and list of changed files.
Changeset
A snapshot of the state of the repository used to record a
change.
Changeset, child
The converse of parent changeset: if P is a parent of C, then C
is a child of P. There is no limit to the number of children
that a changeset may have.
Changeset id
A SHA-1 hash that uniquely identifies a changeset. It may be
represented as either a "long" 40 hexadecimal digit string, or a
"short" 12 hexadecimal digit string.
Changeset, merge
A changeset with two parents. This occurs when a merge is com‐
mitted.
Changeset, parent
A revision upon which a child changeset is based. Specifically,
a parent changeset of a changeset C is a changeset whose node
immediately precedes C in the DAG. Changesets have at most two
parents.
Checkout
(Noun) The working directory being updated to a specific revi‐
sion. This use should probably be avoided where possible, as
changeset is much more appropriate than checkout in this con‐
text.
Example: "I'm using checkout X."
(Verb) Updating the working directory to a specific changeset.
See hg help update.
Example: "I'm going to check out changeset X."
Child changeset
See 'Changeset, child'.
Close changeset
See 'Head, closed branch'
Closed branch
See 'Branch, closed'.
Clone (Noun) An entire or partial copy of a repository. The partial
clone must be in the form of a revision and its ancestors.
Example: "Is your clone up to date?".
(Verb) The process of creating a clone, using hg clone.
Example: "I'm going to clone the repository".
Closed branch head
See 'Head, closed branch'.
Commit (Noun) A synonym for changeset.
Example: "Is the bug fixed in your recent commit?"
(Verb) The act of recording changes to a repository. When files
are committed in a working directory, Mercurial finds the dif‐
ferences between the committed files and their parent changeset,
creating a new changeset in the repository.
Example: "You should commit those changes now."
Cset A common abbreviation of the term changeset.
DAG The repository of changesets of a distributed version control
system (DVCS) can be described as a directed acyclic graph
(DAG), consisting of nodes and edges, where nodes correspond to
changesets and edges imply a parent -> child relation. This
graph can be visualized by graphical tools such as hg glog
(graphlog). In Mercurial, the DAG is limited by the requirement
for children to have at most two parents.
Default branch
See 'Branch, default'.
Descendant
Any changeset that can be reached by a chain of child changesets
from a given changeset. More precisely, the descendants of a
changeset can be defined by two properties: the child of a
changeset is a descendant, and the child of a descendant is a
descendant. See also: 'Ancestor'.
Diff (Noun) The difference between the contents and attributes of
files in two changesets or a changeset and the current working
directory. The difference is usually represented in a standard
form called a "diff" or "patch". The "git diff" format is used
when the changes include copies, renames, or changes to file
attributes, none of which can be represented/handled by classic
"diff" and "patch".
Example: "Did you see my correction in the diff?"
(Verb) Diffing two changesets is the action of creating a diff
or patch.
Example: "If you diff with changeset X, you will see what I
mean."
Directory, working
The working directory represents the state of the files tracked
by Mercurial, that will be recorded in the next commit. The
working directory initially corresponds to the snapshot at an
existing changeset, known as the parent of the working direc‐
tory. See 'Parent, working directory'. The state may be modified
by changes to the files introduced manually or by a merge. The
repository metadata exists in the .hg directory inside the work‐
ing directory.
Draft Changesets in the draft phase have not been shared with publish‐
ing repositories and may thus be safely changed by history-modi‐
fying extensions. See hg help phases.
Graph See DAG and hg help graphlog.
Head The term 'head' may be used to refer to both a branch head or a
repository head, depending on the context. See 'Head, branch'
and 'Head, repository' for specific definitions.
Heads are where development generally takes place and are the
usual targets for update and merge operations.
Head, branch
A changeset with no descendants on the same named branch.
Head, closed branch
A changeset that marks a head as no longer interesting. The
closed head is no longer listed by hg heads. A branch is consid‐
ered closed when all its heads are closed and consequently is
not listed by hg branches.
Closed heads can be re-opened by committing new changeset as the
child of the changeset that marks a head as closed.
Head, repository
A topological head which has not been closed.
Head, topological
A changeset with no children in the repository.
History, immutable
Once committed, changesets cannot be altered. Extensions which
appear to change history actually create new changesets that
replace existing ones, and then destroy the old changesets.
Doing so in public repositories can result in old changesets
being reintroduced to the repository.
History, rewriting
The changesets in a repository are immutable. However, exten‐
sions to Mercurial can be used to alter the repository, usually
in such a way as to preserve changeset contents.
Immutable history
See 'History, immutable'.
Merge changeset
See 'Changeset, merge'.
Manifest
Each changeset has a manifest, which is the list of files that
are tracked by the changeset.
Merge Used to bring together divergent branches of work. When you
update to a changeset and then merge another changeset, you
bring the history of the latter changeset into your working
directory. Once conflicts are resolved (and marked), this merge
may be committed as a merge changeset, bringing two branches
together in the DAG.
Named branch
See 'Branch, named'.
Null changeset
The empty changeset. It is the parent state of newly-initialized
repositories and repositories with no checked out revision. It
is thus the parent of root changesets and the effective ancestor
when merging unrelated changesets. Can be specified by the alias
'null' or by the changeset ID '000000000000'.
Parent See 'Changeset, parent'.
Parent changeset
See 'Changeset, parent'.
Parent, working directory
The working directory parent reflects a virtual revision which
is the child of the changeset (or two changesets with an uncom‐
mitted merge) shown by hg parents. This is changed with hg
update. Other commands to see the working directory parent are
hg summary and hg id. Can be specified by the alias ".".
Patch (Noun) The product of a diff operation.
Example: "I've sent you my patch."
(Verb) The process of using a patch file to transform one
changeset into another.
Example: "You will need to patch that revision."
Phase A per-changeset state tracking how the changeset has been or
should be shared. See hg help phases.
Public Changesets in the public phase have been shared with publishing
repositories and are therefore considered immutable. See hg help
phases.
Pull An operation in which changesets in a remote repository which
are not in the local repository are brought into the local
repository. Note that this operation without special arguments
only updates the repository, it does not update the files in the
working directory. See hg help pull.
Push An operation in which changesets in a local repository which are
not in a remote repository are sent to the remote repository.
Note that this operation only adds changesets which have been
committed locally to the remote repository. Uncommitted changes
are not sent. See hg help push.
Repository
The metadata describing all recorded states of a collection of
files. Each recorded state is represented by a changeset. A
repository is usually (but not always) found in the .hg subdi‐
rectory of a working directory. Any recorded state can be recre‐
ated by "updating" a working directory to a specific changeset.
Repository head
See 'Head, repository'.
Revision
A state of the repository at some point in time. Earlier revi‐
sions can be updated to by using hg update. See also 'Revision
number'; See also 'Changeset'.
Revision number
This integer uniquely identifies a changeset in a specific
repository. It represents the order in which changesets were
added to a repository, starting with revision number 0. Note
that the revision number may be different in each clone of a
repository. To identify changesets uniquely between different
clones, see 'Changeset id'.
Revlog History storage mechanism used by Mercurial. It is a form of
delta encoding, with occasional full revision of data followed
by delta of each successive revision. It includes data and an
index pointing to the data.
Rewriting history
See 'History, rewriting'.
Root A changeset that has only the null changeset as its parent. Most
repositories have only a single root changeset.
Secret Changesets in the secret phase may not be shared via push, pull,
or clone. See hg help phases.
Tag An alternative name given to a changeset. Tags can be used in
all places where Mercurial expects a changeset ID, e.g., with hg
update. The creation of a tag is stored in the history and will
thus automatically be shared with other using push and pull.
Tip The changeset with the highest revision number. It is the
changeset most recently added in a repository.
Tip, branch
The head of a given branch with the highest revision number.
When a branch name is used as a revision identifier, it refers
to the branch tip. See also 'Branch, head'. Note that because
revision numbers may be different in different repository
clones, the branch tip may be different in different cloned
repositories.
Update (Noun) Another synonym of changeset.
Example: "I've pushed an update".
(Verb) This term is usually used to describe updating the state
of the working directory to that of a specific changeset. See hg
help update.
Example: "You should update".
Working directory
See 'Directory, working'.
Working directory parent
See 'Parent, working directory'.
SYNTAX FOR MERCURIAL IGNORE FILESSYNOPSIS
The Mercurial system uses a file called .hgignore in the root directory
of a repository to control its behavior when it searches for files that
it is not currently tracking.
DESCRIPTION
The working directory of a Mercurial repository will often contain
files that should not be tracked by Mercurial. These include backup
files created by editors and build products created by compilers.
These files can be ignored by listing them in a .hgignore file in the
root of the working directory. The .hgignore file must be created manu‐
ally. It is typically put under version control, so that the settings
will propagate to other repositories with push and pull.
An untracked file is ignored if its path relative to the repository
root directory, or any prefix path of that path, is matched against any
pattern in .hgignore.
For example, say we have an untracked file, file.c, at a/b/file.c
inside our repository. Mercurial will ignore file.c if any pattern in
.hgignore matches a/b/file.c, a/b or a.
In addition, a Mercurial configuration file can reference a set of
per-user or global ignore files. See the ignore configuration key on
the [ui] section of hg help config for details of how to configure
these files.
To control Mercurial's handling of files that it manages, many commands
support the -I and -X options; see hg help <command> and hg help pat‐
terns for details.
SYNTAX
An ignore file is a plain text file consisting of a list of patterns,
with one pattern per line. Empty lines are skipped. The # character is
treated as a comment character, and the \ character is treated as an
escape character.
Mercurial supports several pattern syntaxes. The default syntax used is
Python/Perl-style regular expressions.
To change the syntax used, use a line of the following form:
syntax: NAME
where NAME is one of the following:
regexp
Regular expression, Python/Perl syntax.
glob
Shell-style glob.
The chosen syntax stays in effect when parsing all patterns that fol‐
low, until another syntax is selected.
Neither glob nor regexp patterns are rooted. A glob-syntax pattern of
the form *.c will match a file ending in .c in any directory, and a
regexp pattern of the form \.c$ will do the same. To root a regexp pat‐
tern, start it with ^.
Note Patterns specified in other than .hgignore are always rooted.
Please see hg help patterns for details.
EXAMPLE
Here is an example ignore file.
# use glob syntax.
syntax: glob
*.elc
*.pyc
*~
# switch to regexp syntax.
syntax: regexp
^\.pc/
CONFIGURING HGWEB
Mercurial's internal web server, hgweb, can serve either a single
repository, or a collection of them. In the latter case, a special con‐
figuration file can be used to specify the repository paths to use and
global web configuration options.
This file uses the same syntax as other Mercurial configuration files,
but only the following sections are recognized:
· web
· paths
· collections
The web section can specify all the settings described in the web sec‐
tion of the hgrc(5) documentation. See hg help config for information
on where to find the manual page.
The paths section provides mappings of physical repository paths to
virtual ones. For instance:
[paths]
projects/a = /foo/bar
projects/b = /baz/quux
web/root = /real/root/*
/ = /real/root2/*
virtual/root2 = /real/root2/**
· The first two entries make two repositories in different directories
appear under the same directory in the web interface
· The third entry maps every Mercurial repository found in '/real/root'
into 'web/root'. This format is preferred over the [collections] one,
since using absolute paths as configuration keys is not supported on
every platform (especially on Windows).
· The fourth entry is a special case mapping all repositories in
'/real/root2' in the root of the virtual directory.
· The fifth entry recursively finds all repositories under the real
root, and maps their relative paths under the virtual root.
The collections section provides mappings of trees of physical reposi‐
tories paths to virtual ones, though the paths syntax is generally pre‐
ferred. For instance:
[collections]
/foo = /foo
Here, the left side will be stripped off all repositories found in the
right side. Thus /foo/bar and foo/quux/baz will be listed as bar and
quux/baz respectively.
MERGE TOOLS
To merge files Mercurial uses merge tools.
A merge tool combines two different versions of a file into a merged
file. Merge tools are given the two files and the greatest common
ancestor of the two file versions, so they can determine the changes
made on both branches.
Merge tools are used both for hg resolve, hg merge, hg update, hg back‐
out and in several extensions.
Usually, the merge tool tries to automatically reconcile the files by
combining all non-overlapping changes that occurred separately in the
two different evolutions of the same initial base file. Furthermore,
some interactive merge programs make it easier to manually resolve con‐
flicting merges, either in a graphical way, or by inserting some con‐
flict markers. Mercurial does not include any interactive merge pro‐
grams but relies on external tools for that.
Available merge tools
External merge tools and their properties are configured in the
merge-tools configuration section - see hgrc(5) - but they can often
just be named by their executable.
A merge tool is generally usable if its executable can be found on the
system and if it can handle the merge. The executable is found if it is
an absolute or relative executable path or the name of an application
in the executable search path. The tool is assumed to be able to handle
the merge if it can handle symlinks if the file is a symlink, if it can
handle binary files if the file is binary, and if a GUI is available if
the tool requires a GUI.
There are some internal merge tools which can be used. The internal
merge tools are:
internal:dump
Creates three versions of the files to merge, containing the
contents of local, other and base. These files can then be used
to perform a merge manually. If the file to be merged is named
a.txt, these files will accordingly be named a.txt.local,
a.txt.other and a.txt.base and they will be placed in the same
directory as a.txt.
internal:fail
Rather than attempting to merge files that were modified on both
branches, it marks them as unresolved. The resolve command must
be used to resolve these conflicts.
internal:local
Uses the local version of files as the merged version.
internal:merge
Uses the internal non-interactive simple merge algorithm for
merging files. It will fail if there are any conflicts and leave
markers in the partially merged file.
internal:other
Uses the other version of files as the merged version.
internal:prompt
Asks the user which of the local or the other version to keep as
the merged version.
Internal tools are always available and do not require a GUI but will
by default not handle symlinks or binary files.
Choosing a merge tool
Mercurial uses these rules when deciding which merge tool to use:
1. If a tool has been specified with the --tool option to merge or
resolve, it is used. If it is the name of a tool in the merge-tools
configuration, its configuration is used. Otherwise the specified
tool must be executable by the shell.
2. If the HGMERGE environment variable is present, its value is used
and must be executable by the shell.
3. If the filename of the file to be merged matches any of the patterns
in the merge-patterns configuration section, the first usable merge
tool corresponding to a matching pattern is used. Here, binary capa‐
bilities of the merge tool are not considered.
4. If ui.merge is set it will be considered next. If the value is not
the name of a configured tool, the specified value is used and must
be executable by the shell. Otherwise the named tool is used if it
is usable.
5. If any usable merge tools are present in the merge-tools configura‐
tion section, the one with the highest priority is used.
6. If a program named hgmerge can be found on the system, it is used -
but it will by default not be used for symlinks and binary files.
7. If the file to be merged is not binary and is not a symlink, then
internal:merge is used.
8. The merge of the file fails and must be resolved before commit.
Note After selecting a merge program, Mercurial will by default
attempt to merge the files using a simple merge algorithm first.
Only if it doesn't succeed because of conflicting changes Mercu‐
rial will actually execute the merge program. Whether to use the
simple merge algorithm first can be controlled by the premerge
setting of the merge tool. Premerge is enabled by default unless
the file is binary or a symlink.
See the merge-tools and ui sections of hgrc(5) for details on the con‐
figuration of merge tools.
SPECIFYING MULTIPLE REVISIONS
When Mercurial accepts more than one revision, they may be specified
individually, or provided as a topologically continuous range, sepa‐
rated by the ":" character.
The syntax of range notation is [BEGIN]:[END], where BEGIN and END are
revision identifiers. Both BEGIN and END are optional. If BEGIN is not
specified, it defaults to revision number 0. If END is not specified,
it defaults to the tip. The range ":" thus means "all revisions".
If BEGIN is greater than END, revisions are treated in reverse order.
A range acts as a closed interval. This means that a range of 3:5 gives
3, 4 and 5. Similarly, a range of 9:6 gives 9, 8, 7, and 6.
FILE NAME PATTERNS
Mercurial accepts several notations for identifying one or more files
at a time.
By default, Mercurial treats filenames as shell-style extended glob
patterns.
Alternate pattern notations must be specified explicitly.
Note Patterns specified in .hgignore are not rooted. Please see hg
help hgignore for details.
To use a plain path name without any pattern matching, start it with
path:. These path names must completely match starting at the current
repository root.
To use an extended glob, start a name with glob:. Globs are rooted at
the current directory; a glob such as *.c will only match files in the
current directory ending with .c.
The supported glob syntax extensions are ** to match any string across
path separators and {a,b} to mean "a or b".
To use a Perl/Python regular expression, start a name with re:. Regexp
pattern matching is anchored at the root of the repository.
To read name patterns from a file, use listfile: or listfile0:. The
latter expects null delimited patterns while the former expects line
feeds. Each string read from the file is itself treated as a file pat‐
tern.
Plain examples:
path:foo/bar a name bar in a directory named foo in the root
of the repository
path:path:name a file or directory named "path:name"
Glob examples:
glob:*.c any name ending in ".c" in the current directory
*.c any name ending in ".c" in the current directory
**.c any name ending in ".c" in any subdirectory of the
current directory including itself.
foo/*.c any name ending in ".c" in the directory foo
foo/**.c any name ending in ".c" in any subdirectory of foo
including itself.
Regexp examples:
re:.*\.c$ any name ending in ".c", anywhere in the repository
File examples:
listfile:list.txt read list from list.txt with one file pattern per line
listfile0:list.txt read list from list.txt with null byte delimiters
See also hg help filesets.
WORKING WITH PHASESWHAT ARE PHASES?
Phases are a system for tracking which changesets have been or should
be shared. This helps prevent common mistakes when modifying history
(for instance, with the mq or rebase extensions).
Each changeset in a repository is in one of the following phases:
· public : changeset is visible on a public server
· draft : changeset is not yet published
· secret : changeset should not be pushed, pulled, or cloned
These phases are ordered (public < draft < secret) and no changeset can
be in a lower phase than its ancestors. For instance, if a changeset is
public, all its ancestors are also public. Lastly, changeset phases
should only be changed towards the public phase.
HOW ARE PHASES MANAGED?
For the most part, phases should work transparently. By default, a
changeset is created in the draft phase and is moved into the public
phase when it is pushed to another repository.
Once changesets become public, extensions like mq and rebase will
refuse to operate on them to prevent creating duplicate changesets.
Phases can also be manually manipulated with the hg phase command if
needed. See hg help -v phase for examples.
PHASES AND SERVERS
Normally, all servers are publishing by default. This means:
- all draft changesets that are pulled or cloned appear in phase
public on the client
- all draft changesets that are pushed appear as public on both
client and server
- secret changesets are neither pushed, pulled, or cloned
Note Pulling a draft changeset from a publishing server does not mark
it as public on the server side due to the read-only nature of
pull.
Sometimes it may be desirable to push and pull changesets in the draft
phase to share unfinished work. This can be done by setting a reposi‐
tory to disable publishing in its configuration file:
[phases]
publish = False
See hg help config for more information on config files.
Note Servers running older versions of Mercurial are treated as pub‐
lishing.
EXAMPLES
· list changesets in draft or secret phase:
hg log -r "not public()"
· change all secret changesets to draft:
hg phase --draft "secret()"
· forcibly move the current changeset and descendants from public to
draft:
hg phase --force --draft .
· show a list of changeset revision and phase:
hg log --template "{rev} {phase}\n"
· resynchronize draft changesets relative to a remote repository:
hg phase -fd 'outgoing(URL)'
See hg help phase for more information on manually manipulating phases.
SPECIFYING SINGLE REVISIONS
Mercurial supports several ways to specify individual revisions.
A plain integer is treated as a revision number. Negative integers are
treated as sequential offsets from the tip, with -1 denoting the tip,
-2 denoting the revision prior to the tip, and so forth.
A 40-digit hexadecimal string is treated as a unique revision identi‐
fier.
A hexadecimal string less than 40 characters long is treated as a
unique revision identifier and is referred to as a short-form identi‐
fier. A short-form identifier is only valid if it is the prefix of
exactly one full-length identifier.
Any other string is treated as a tag or branch name. A tag name is a
symbolic name associated with a revision identifier. A branch name
denotes the tipmost revision of that branch. Tag and branch names must
not contain the ":" character.
The reserved name "tip" is a special tag that always identifies the
most recent revision.
The reserved name "null" indicates the null revision. This is the revi‐
sion of an empty repository, and the parent of revision 0.
The reserved name "." indicates the working directory parent. If no
working directory is checked out, it is equivalent to null. If an
uncommitted merge is in progress, "." is the revision of the first par‐
ent.
SPECIFYING REVISION SETS
Mercurial supports a functional language for selecting a set of revi‐
sions.
The language supports a number of predicates which are joined by infix
operators. Parenthesis can be used for grouping.
Identifiers such as branch names may need quoting with single or double
quotes if they contain characters like - or if they match one of the
predefined predicates.
Special characters can be used in quoted identifiers by escaping them,
e.g., \n is interpreted as a newline. To prevent them from being inter‐
preted, strings can be prefixed with r, e.g. r'...'.
There is a single prefix operator:
not x
Changesets not in x. Short form is ! x.
These are the supported infix operators:
x::y
A DAG range, meaning all changesets that are descendants of x
and ancestors of y, including x and y themselves. If the first
endpoint is left out, this is equivalent to ancestors(y), if the
second is left out it is equivalent to descendants(x).
An alternative syntax is x..y.
x:y
All changesets with revision numbers between x and y, both
inclusive. Either endpoint can be left out, they default to 0
and tip.
x and y
The intersection of changesets in x and y. Short form is x & y.
x or y
The union of changesets in x and y. There are two alternative
short forms: x | y and x + y.
x - y
Changesets in x but not in y.
x^n
The nth parent of x, n == 0, 1, or 2. For n == 0, x; for n ==
1, the first parent of each changeset in x; for n == 2, the sec‐
ond parent of changeset in x.
x~n
The nth first ancestor of x; x~0 is x; x~3 is x^^^.
There is a single postfix operator:
x^
Equivalent to x^1, the first parent of each changeset in x.
The following predicates are supported:
adds(pattern)
Changesets that add a file matching pattern.
all()
All changesets, the same as 0:tip.
ancestor(single, single)
Greatest common ancestor of the two changesets.
ancestors(set)
Changesets that are ancestors of a changeset in set.
author(string)
Alias for user(string).
bisect(string)
Changesets marked in the specified bisect status:
· good, bad, skip: csets explicitly marked as good/bad/skip
· goods, bads : csets topologicaly good/bad
· range : csets taking part in the bisection
· pruned : csets that are goods, bads or skipped
· untested : csets whose fate is yet unknown
· ignored : csets ignored due to DAG topology
bookmark([name])
The named bookmark or all bookmarks.
branch(string or set)
All changesets belonging to the given branch or the branches of
the given changesets.
children(set)
Child changesets of changesets in set.
closed()
Changeset is closed.
contains(pattern)
Revision contains a file matching pattern. See hg help patterns
for information about file patterns.
date(interval)
Changesets within the interval, see hg help dates.
desc(string)
Search commit message for string. The match is case-insensitive.
descendants(set)
Changesets which are descendants of changesets in set.
draft()
Changeset in draft phase.
file(pattern)
Changesets affecting files matched by pattern.
filelog(pattern)
Changesets connected to the specified filelog.
first(set, [n])
An alias for limit().
follow([file])
An alias for ::. (ancestors of the working copy's first parent).
If a filename is specified, the history of the given file is
followed, including copies.
grep(regex)
Like keyword(string) but accepts a regex. Use grep(r'...') to
ensure special escape characters are handled correctly. Unlike
keyword(string), the match is case-sensitive.
head()
Changeset is a named branch head.
heads(set)
Members of set with no children in set.
id(string)
Revision non-ambiguously specified by the given hex string pre‐
fix.
keyword(string)
Search commit message, user name, and names of changed files for
string. The match is case-insensitive.
last(set, [n])
Last n members of set, defaulting to 1.
limit(set, [n])
First n members of set, defaulting to 1.
matching(revision [, field])
Changesets in which a given set of fields match the set of
fields in the selected revision or set.
To match more than one field pass the list of fields to match
separated by spaces (e.g. author description).
Valid fields are most regular revision fields and some special
fields.
Regular revision fields are description, author, branch, date,
files, phase, parents, substate and user. Note that author and
user are synonyms.
Special fields are summary and metadata: summary matches the
first line of the description. metadata is equivalent to match‐
ing description user date (i.e. it matches the main metadata
fields).
metadata is the default field which is used when no fields are
specified. You can match more than one field at a time.
max(set)
Changeset with highest revision number in set.
merge()
Changeset is a merge changeset.
min(set)
Changeset with lowest revision number in set.
modifies(pattern)
Changesets modifying files matched by pattern.
outgoing([path])
Changesets not found in the specified destination repository, or
the default push location.
p1([set])
First parent of changesets in set, or the working directory.
p2([set])
Second parent of changesets in set, or the working directory.
parents([set])
The set of all parents for all changesets in set, or the working
directory.
present(set)
An empty set, if any revision in set isn't found; otherwise, all
revisions in set.
If any of specified revisions is not present in the local repos‐
itory, the query is normally aborted. But this predicate allows
the query to continue even in such cases.
public()
Changeset in public phase.
remote([id [,path]])
Local revision that corresponds to the given identifier in a
remote repository, if present. Here, the '.' identifier is a
synonym for the current local branch.
removes(pattern)
Changesets which remove files matching pattern.
rev(number)
Revision with the given numeric identifier.
reverse(set)
Reverse order of set.
roots(set)
Changesets in set with no parent changeset in set.
secret()
Changeset in secret phase.
sort(set[, [-]key...])
Sort set by keys. The default sort order is ascending, specify a
key as -key to sort in descending order.
The keys can be:
· rev for the revision number,
· branch for the branch name,
· desc for the commit message (description),
· user for user name (author can be used as an alias),
· date for the commit date
tag([name])
The specified tag by name, or all tagged revisions if no name is
given.
user(string)
User name contains string. The match is case-insensitive.
New predicates (known as "aliases") can be defined, using any combina‐
tion of existing predicates or other aliases. An alias definition looks
like:
<alias> = <definition>
in the revsetalias section of a Mercurial configuration file. Arguments
of the form $1, $2, etc. are substituted from the alias into the defi‐
nition.
For example,
[revsetalias]
h = heads()
d($1) = sort($1, date)
rs($1, $2) = reverse(sort($1, $2))
defines three aliases, h, d, and rs. rs(0:tip, author) is exactly
equivalent to reverse(sort(0:tip, author)).
Command line equivalents for hg log:
-f -> ::.
-d x -> date(x)-k x -> keyword(x)-m -> merge()-u x -> user(x)-b x -> branch(x)-P x -> !::x
-l x -> limit(expr, x)
Some sample queries:
· Changesets on the default branch:
hg log -r "branch(default)"
· Changesets on the default branch since tag 1.5 (excluding merges):
hg log -r "branch(default) and 1.5:: and not merge()"
· Open branch heads:
hg log -r "head() and not closed()"
· Changesets between tags 1.3 and 1.5 mentioning "bug" that affect
hgext/*:
hg log -r "1.3::1.5 and keyword(bug) and file('hgext/*')"
· Changesets committed in May 2008, sorted by user:
hg log -r "sort(date('May 2008'), user)"
· Changesets mentioning "bug" or "issue" that are not in a tagged
release:
hg log -r "(keyword(bug) or keyword(issue)) and not ancestors(tagged())"
SUBREPOSITORIES
Subrepositories let you nest external repositories or projects into a
parent Mercurial repository, and make commands operate on them as a
group.
Mercurial currently supports Mercurial, Git, and Subversion subreposi‐
tories.
Subrepositories are made of three components:
1. Nested repository checkouts. They can appear anywhere in the parent
working directory.
2. Nested repository references. They are defined in .hgsub, which
should be placed in the root of working directory, and tell where
the subrepository checkouts come from. Mercurial subrepositories are
referenced like:
path/to/nested = https://example.com/nested/repo/path
Git and Subversion subrepos are also supported:
path/to/nested = [git]git://example.com/nested/repo/path
path/to/nested = [svn]https://example.com/nested/trunk/path
where path/to/nested is the checkout location relatively to the par‐
ent Mercurial root, and https://example.com/nested/repo/path is the
source repository path. The source can also reference a filesystem
path.
Note that .hgsub does not exist by default in Mercurial reposito‐
ries, you have to create and add it to the parent repository before
using subrepositories.
3. Nested repository states. They are defined in .hgsubstate, which is
placed in the root of working directory, and capture whatever infor‐
mation is required to restore the subrepositories to the state they
were committed in a parent repository changeset. Mercurial automati‐
cally record the nested repositories states when committing in the
parent repository.
Note
The .hgsubstate file should not be edited manually.
ADDING A SUBREPOSITORY
If .hgsub does not exist, create it and add it to the parent reposi‐
tory. Clone or checkout the external projects where you want it to live
in the parent repository. Edit .hgsub and add the subrepository entry
as described above. At this point, the subrepository is tracked and the
next commit will record its state in .hgsubstate and bind it to the
committed changeset.
SYNCHRONIZING A SUBREPOSITORY
Subrepos do not automatically track the latest changeset of their
sources. Instead, they are updated to the changeset that corresponds
with the changeset checked out in the top-level changeset. This is so
developers always get a consistent set of compatible code and libraries
when they update.
Thus, updating subrepos is a manual process. Simply check out target
subrepo at the desired revision, test in the top-level repo, then com‐
mit in the parent repository to record the new combination.
DELETING A SUBREPOSITORY
To remove a subrepository from the parent repository, delete its refer‐
ence from .hgsub, then remove its files.
INTERACTION WITH MERCURIAL COMMANDS
add add does not recurse in subrepos unless -S/--subrepos is speci‐
fied. However, if you specify the full path of a file in a sub‐
repo, it will be added even without -S/--subrepos specified.
Git and Subversion subrepositories are currently silently
ignored.
archive
archive does not recurse in subrepositories unless -S/--subrepos
is specified.
commit commit creates a consistent snapshot of the state of the entire
project and its subrepositories. If any subrepositories have
been modified, Mercurial will abort. Mercurial can be made to
instead commit all modified subrepositories by specifying
-S/--subrepos, or setting "ui.commitsubrepos=True" in a configu‐
ration file (see hg help config). After there are no longer any
modified subrepositories, it records their state and finally
commits it in the parent repository.
diff diff does not recurse in subrepos unless -S/--subrepos is speci‐
fied. Changes are displayed as usual, on the subrepositories
elements. Git and Subversion subrepositories are currently
silently ignored.
forget forget currently only handles exact file matches in subrepos.
Git and Subversion subrepositories are currently silently
ignored.
incoming
incoming does not recurse in subrepos unless -S/--subrepos is
specified. Git and Subversion subrepositories are currently
silently ignored.
outgoing
outgoing does not recurse in subrepos unless -S/--subrepos is
specified. Git and Subversion subrepositories are currently
silently ignored.
pull pull is not recursive since it is not clear what to pull prior
to running hg update. Listing and retrieving all subrepositories
changes referenced by the parent repository pulled changesets is
expensive at best, impossible in the Subversion case.
push Mercurial will automatically push all subrepositories first when
the parent repository is being pushed. This ensures new sub‐
repository changes are available when referenced by top-level
repositories. Push is a no-op for Subversion subrepositories.
status status does not recurse into subrepositories unless -S/--subre‐
pos is specified. Subrepository changes are displayed as regular
Mercurial changes on the subrepository elements. Subversion sub‐
repositories are currently silently ignored.
update update restores the subrepos in the state they were originally
committed in target changeset. If the recorded changeset is not
available in the current subrepository, Mercurial will pull it
in first before updating. This means that updating can require
network access when using subrepositories.
REMAPPING SUBREPOSITORIES SOURCES
A subrepository source location may change during a project life,
invalidating references stored in the parent repository history. To fix
this, rewriting rules can be defined in parent repository hgrc file or
in Mercurial configuration. See the [subpaths] section in hgrc(5) for
more details.
TEMPLATE USAGE
Mercurial allows you to customize output of commands through templates.
You can either pass in a template from the command line, via the --tem‐
plate option, or select an existing template-style (--style).
You can customize output for any "log-like" command: log, outgoing,
incoming, tip, parents, heads and glog.
Four styles are packaged with Mercurial: default (the style used when
no explicit preference is passed), compact, changelog, and xml. Usage:
$ hg log -r1 --style changelog
A template is a piece of text, with markup to invoke variable expan‐
sion:
$ hg log -r1 --template "{node}\n"
b56ce7b07c52de7d5fd79fb89701ea538af65746
Strings in curly braces are called keywords. The availability of key‐
words depends on the exact context of the templater. These keywords are
usually available for templating a log-like command:
author String. The unmodified author of the changeset.
bisect String. The changeset bisection status.
bookmarks
List of strings. Any bookmarks associated with the changeset.
branch String. The name of the branch on which the changeset was com‐
mitted.
branches
List of strings. The name of the branch on which the changeset
was committed. Will be empty if the branch name was default.
children
List of strings. The children of the changeset.
date Date information. The date when the changeset was committed.
desc String. The text of the changeset description.
diffstat
String. Statistics of changes with the following format: "modi‐
fied files: +added/-removed lines"
file_adds
List of strings. Files added by this changeset.
file_copies
List of strings. Files copied in this changeset with their
sources.
file_copies_switch
List of strings. Like "file_copies" but displayed only if the
--copied switch is set.
file_dels
List of strings. Files removed by this changeset.
file_mods
List of strings. Files modified by this changeset.
files List of strings. All files modified, added, or removed by this
changeset.
latesttag
String. Most recent global tag in the ancestors of this change‐
set.
latesttagdistance
Integer. Longest path to the latest tag.
node String. The changeset identification hash, as a 40 hexadecimal
digit string.
phase String. The changeset phase name.
phaseidx
Integer. The changeset phase index.
rev Integer. The repository-local changeset revision number.
tags List of strings. Any tags associated with the changeset.
The "date" keyword does not produce human-readable output. If you want
to use a date in your output, you can use a filter to process it. Fil‐
ters are functions which return a string based on the input variable.
Be sure to use the stringify filter first when you're applying a
string-input filter to a list-like input variable. You can also use a
chain of filters to get the desired output:
$ hg tip --template "{date|isodate}\n"
2008-08-21 18:22 +0000
List of filters:
addbreaks
Any text. Add an XHTML "<br />" tag before the end of every line
except the last.
age Date. Returns a human-readable date/time difference between the
given date/time and the current date/time.
basename
Any text. Treats the text as a path, and returns the last compo‐
nent of the path after splitting by the path separator (ignoring
trailing separators). For example, "foo/bar/baz" becomes "baz"
and "foo/bar//" becomes "bar".
date Date. Returns a date in a Unix date format, including the time‐
zone: "Mon Sep 04 15:13:13 2006 0700".
domain Any text. Finds the first string that looks like an email
address, and extracts just the domain component. Example: User
<user@example.com> becomes example.com.
email Any text. Extracts the first string that looks like an email
address. Example: User <user@example.com> becomes user@exam‐
ple.com.
emailuser
Any text. Returns the user portion of an email address.
escape Any text. Replaces the special XML/XHTML characters "&", "<" and
">" with XML entities.
fill68 Any text. Wraps the text to fit in 68 columns.
fill76 Any text. Wraps the text to fit in 76 columns.

"2009-08-18 13:00:13 +0200". See also the rfc3339date filter.
localdate
Date. Converts a date to local date.
nonempty
Any text. Returns '(none)' if the string is empty.

ers: "Tue, 18 Aug 2009 13:00:13 +0200".
short Changeset hash. Returns the short form of a changeset hash, i.e.
a 12 hexadecimal digit string.
shortbisect
Any text. Treats text as a bisection status, and returns a sin‐
gle-character representing the status (G: good, B: bad, S:
skipped, U: untested, I: ignored). Returns single space if text
is not a valid bisection status.
shortdate
Date. Returns a date like "2006-09-18".

address.
URL PATHS
Valid URLs are of the form:
local/filesystem/path[#revision]
file://local/filesystem/path[#revision]
http://[user[:pass]@]host[:port]/[path][#revision]
https://[user[:pass]@]host[:port]/[path][#revision]
ssh://[user@]host[:port]/[path][#revision]
Paths in the local filesystem can either point to Mercurial reposito‐
ries or to bundle files (as created by hg bundle or :hg:` incoming
--bundle`). See also hg help paths.
An optional identifier after # indicates a particular branch, tag, or
changeset to use from the remote repository. See also hg help revisions
.
Some features, such as pushing to http:// and https:// URLs are only
possible if the feature is explicitly enabled on the remote Mercurial
server.
Note that the security of HTTPS URLs depends on proper configuration of
web.cacerts.
Some notes about using SSH with Mercurial:
· SSH requires an accessible shell account on the destination machine
and a copy of hg in the remote path or specified with as remotecmd.
· path is relative to the remote user's home directory by default. Use
an extra slash at the start of a path to specify an absolute path:
ssh://example.com//tmp/repository
· Mercurial doesn't use its own compression via SSH; the right thing to
do is to configure it in your ~/.ssh/config, e.g.:
Host *.mylocalnetwork.example.com
Compression no
Host *
Compression yes
Alternatively specify "ssh -C" as your ssh command in your configura‐
tion file or with the --ssh command line option.
These URLs can all be stored in your configuration file with path
aliases under the [paths] section like so:
[paths]
alias1 = URL1
alias2 = URL2
...
You can then use the alias for any command that uses a URL (for example
hg pull alias1 will be treated as hg pull URL1).
Two path aliases are special because they are used as defaults when you
do not provide the URL to a command:
default:
When you create a repository with hg clone, the clone command
saves the location of the source repository as the new reposi‐
tory's 'default' path. This is then used when you omit path from
push- and pull-like commands (including incoming and outgoing).
default-push:
The push command will look for a path named 'default-push', and
prefer it over 'default' if both are defined.
EXTENSIONS
This section contains help for extensions that are distributed together
with Mercurial. Help for other extensions is available in the help sys‐
tem.
acl
hooks for controlling repository access
This hook makes it possible to allow or deny write access to given
branches and paths of a repository when receiving incoming changesets
via pretxnchangegroup and pretxncommit.
The authorization is matched based on the local user name on the system
where the hook runs, and not the committer of the original changeset
(since the latter is merely informative).
The acl hook is best used along with a restricted shell like hgsh, pre‐
venting authenticating users from doing anything other than pushing or
pulling. The hook is not safe to use if users have interactive shell
access, as they can then disable the hook. Nor is it safe if remote
users share an account, because then there is no way to distinguish
them.
The order in which access checks are performed is:
1. Deny list for branches (section acl.deny.branches)
2. Allow list for branches (section acl.allow.branches)
3. Deny list for paths (section acl.deny)
4. Allow list for paths (section acl.allow)
The allow and deny sections take key-value pairs.
Branch-based Access Control
Use the acl.deny.branches and acl.allow.branches sections to have
branch-based access control. Keys in these sections can be either:
· a branch name, or
· an asterisk, to match any branch;
The corresponding values can be either:
· a comma-separated list containing users and groups, or
· an asterisk, to match anyone;
Path-based Access Control
Use the acl.deny and acl.allow sections to have path-based access con‐
trol. Keys in these sections accept a subtree pattern (with a glob syn‐
tax by default). The corresponding values follow the same syntax as the
other sections above.
Groups
Group names must be prefixed with an @ symbol. Specifying a group name
has the same effect as specifying all the users in that group.
You can define group members in the acl.groups section. If a group
name is not defined there, and Mercurial is running under a Unix-like
system, the list of users will be taken from the OS. Otherwise, an
exception will be raised.
Example Configuration
[hooks]
# Use this if you want to check access restrictions at commit time
pretxncommit.acl = python:hgext.acl.hook
# Use this if you want to check access restrictions for pull, push,
# bundle and serve.
pretxnchangegroup.acl = python:hgext.acl.hook
[acl]
# Allow or deny access for incoming changes only if their source is
# listed here, let them pass otherwise. Source is "serve" for all
# remote access (http or ssh), "push", "pull" or "bundle" when the
# related commands are run locally.
# Default: serve
sources = serve
[acl.deny.branches]
# Everyone is denied to the frozen branch:
frozen-branch = *
# A bad user is denied on all branches:
* = bad-user
[acl.allow.branches]
# A few users are allowed on branch-a:
branch-a = user-1, user-2, user-3
# Only one user is allowed on branch-b:
branch-b = user-1
# The super user is allowed on any branch:
* = super-user
# Everyone is allowed on branch-for-tests:
branch-for-tests = *
[acl.deny]
# This list is checked first. If a match is found, acl.allow is not
# checked. All users are granted access if acl.deny is not present.
# Format for both lists: glob pattern = user, ..., @group, ...
# To match everyone, use an asterisk for the user:
# my/glob/pattern = *
# user6 will not have write access to any file:
** = user6
# Group "hg-denied" will not have write access to any file:
** = @hg-denied
# Nobody will be able to change "DONT-TOUCH-THIS.txt", despite
# everyone being able to change all other files. See below.
src/main/resources/DONT-TOUCH-THIS.txt = *
[acl.allow]
# if acl.allow is not present, all users are allowed by default
# empty acl.allow = no users allowed
# User "doc_writer" has write access to any file under the "docs"
# folder:

# User "jack" and group "designers" have write access to any file
# under the "images" folder:
images/** = jack, @designers
# Everyone (except for "user6" and "@hg-denied" - see acl.deny above)
# will have write access to any file under the "resources" folder
# (except for 1 file. See acl.deny):

bugzilla
hooks for integrating with the Bugzilla bug tracker
This hook extension adds comments on bugs in Bugzilla when changesets
that refer to bugs by Bugzilla ID are seen. The comment is formatted
using the Mercurial template mechanism.
The bug references can optionally include an update for Bugzilla of the
hours spent working on the bug. Bugs can also be marked fixed.
Three basic modes of access to Bugzilla are provided:
1. Access via the Bugzilla XMLRPC interface. Requires Bugzilla 3.4 or
later.
2. Check data via the Bugzilla XMLRPC interface and submit bug change
via email to Bugzilla email interface. Requires Bugzilla 3.4 or
later.
3. Writing directly to the Bugzilla database. Only Bugzilla installa‐
tions using MySQL are supported. Requires Python MySQLdb.
Writing directly to the database is susceptible to schema changes, and
relies on a Bugzilla contrib script to send out bug change notification
emails. This script runs as the user running Mercurial, must be run on
the host with the Bugzilla install, and requires permission to read
Bugzilla configuration details and the necessary MySQL user and pass‐
word to have full access rights to the Bugzilla database. For these
reasons this access mode is now considered deprecated, and will not be
updated for new Bugzilla versions going forward. Only adding comments
is supported in this access mode.
Access via XMLRPC needs a Bugzilla username and password to be speci‐
fied in the configuration. Comments are added under that username.
Since the configuration must be readable by all Mercurial users, it is
recommended that the rights of that user are restricted in Bugzilla to
the minimum necessary to add comments. Marking bugs fixed requires
Bugzilla 4.0 and later.
Access via XMLRPC/email uses XMLRPC to query Bugzilla, but sends email
to the Bugzilla email interface to submit comments to bugs. The From:
address in the email is set to the email address of the Mercurial user,
so the comment appears to come from the Mercurial user. In the event
that the Mercurial user email is not recognised by Bugzilla as a
Bugzilla user, the email associated with the Bugzilla username used to
log into Bugzilla is used instead as the source of the comment. Marking
bugs fixed works on all supported Bugzilla versions.
Configuration items common to all access modes:
bugzilla.version
This access type to use. Values recognised are:
xmlrpc
Bugzilla XMLRPC interface.
xmlrpc+email
Bugzilla XMLRPC and email interfaces.
3.0
MySQL access, Bugzilla 3.0 and later.
2.18
MySQL access, Bugzilla 2.18 and up to but not including
3.0.
2.16
MySQL access, Bugzilla 2.16 and up to but not including
2.18.
bugzilla.regexp
Regular expression to match bug IDs for update in changeset com‐
mit message. It must contain one "()" named group <ids> con‐
taining the bug IDs separated by non-digit characters. It may
also contain a named group <hours> with a floating-point number
giving the hours worked on the bug. If no named groups are
present, the first "()" group is assumed to contain the bug IDs,
and work time is not updated. The default expression matches Bug
1234, Bug no. 1234, Bug number 1234, Bugs 1234,5678, Bug 1234
and 5678 and variations thereof, followed by an hours number
prefixed by h or hours, e.g. hours 1.5. Matching is case insen‐
sitive.
bugzilla.fixregexp
Regular expression to match bug IDs for marking fixed in change‐
set commit message. This must contain a "()" named group <ids>`
containing the bug IDs separated by non-digit characters. It may
also contain a named group ``<hours> with a floating-point num‐
ber giving the hours worked on the bug. If no named groups are
present, the first "()" group is assumed to contain the bug IDs,
and work time is not updated. The default expression matches
Fixes 1234, Fixes bug 1234, Fixes bugs 1234,5678, Fixes 1234 and
5678 and variations thereof, followed by an hours number pre‐
fixed by h or hours, e.g. hours 1.5. Matching is case insensi‐
tive.
bugzilla.fixstatus
The status to set a bug to when marking fixed. Default RESOLVED.
bugzilla.fixresolution
The resolution to set a bug to when marking fixed. Default
FIXED.
bugzilla.style
The style file to use when formatting comments.
bugzilla.template
Template to use when formatting comments. Overrides style if
specified. In addition to the usual Mercurial keywords, the
extension specifies:
{bug}
The Bugzilla bug ID.
{root}
The full pathname of the Mercurial repository.
{webroot}
Stripped pathname of the Mercurial repository.
{hgweb}
Base URL for browsing Mercurial repositories.
Default changeset {node|short} in repo {root} refers to bug
{bug}.\ndetails:\n\t{desc|tabindent}
bugzilla.strip
The number of path separator characters to strip from the front
of the Mercurial repository path ({root} in templates) to pro‐
duce {webroot}. For example, a repository with {root}
/var/local/my-project with a strip of 2 gives a value for {web‐
root} of my-project. Default 0.
web.baseurl
Base URL for browsing Mercurial repositories. Referenced from
templates as {hgweb}.
Configuration items common to XMLRPC+email and MySQL access modes:
bugzilla.usermap
Path of file containing Mercurial committer email to Bugzilla
user email mappings. If specified, the file should contain one
mapping per line:
committer = Bugzilla user
See also the [usermap] section.
The [usermap] section is used to specify mappings of Mercurial commit‐
ter email to Bugzilla user email. See also bugzilla.usermap. Contains
entries of the form committer = Bugzilla user.
XMLRPC access mode configuration:
bugzilla.bzurl
The base URL for the Bugzilla installation. Default
http://localhost/bugzilla.
bugzilla.user
The username to use to log into Bugzilla via XMLRPC. Default
bugs.
bugzilla.password
The password for Bugzilla login.
XMLRPC+email access mode uses the XMLRPC access mode configuration
items, and also:
bugzilla.bzemail
The Bugzilla email address.
In addition, the Mercurial email settings must be configured. See the
documentation in hgrc(5), sections [email] and [smtp].
MySQL access mode configuration:
bugzilla.host
Hostname of the MySQL server holding the Bugzilla database.
Default localhost.
bugzilla.db
Name of the Bugzilla database in MySQL. Default bugs.
bugzilla.user
Username to use to access MySQL server. Default bugs.
bugzilla.password
Password to use to access MySQL server.
bugzilla.timeout
Database connection timeout (seconds). Default 5.
bugzilla.bzuser
Fallback Bugzilla user name to record comments with, if change‐
set committer cannot be found as a Bugzilla user.
bugzilla.bzdir
Bugzilla install directory. Used by default notify. Default
/var/www/html/bugzilla.
bugzilla.notify
The command to run to get Bugzilla to send bug change notifica‐
tion emails. Substitutes from a map with 3 keys, bzdir, id (bug
id) and user (committer bugzilla email). Default depends on ver‐
sion; from 2.18 it is "cd %(bzdir)s && perl -T contrib/sendbug‐
mail.pl %(id)s %(user)s".

children
command to display child changesets
Commands
children
hg children [-r REV] [FILE]
Print the children of the working directory's revisions. If a revision
is given via -r/--rev, the children of that revision will be printed.
If a file argument is given, revision in which the file was last
changed (after the working directory revision or the argument to --rev
if given) is printed.
Options:
-r, --rev
show children of the specified revision
--style
display using template map file
--template
display with template
churn
command to display statistics about repository history
Commands
churn
hg churn [-d DATE] [-r REV] [--aliases FILE] [FILE]
This command will display a histogram representing the number of
changed lines or revisions, grouped according to the given template.
The default template will group changes by author. The --dateformat
option may be used to group the results by date instead.
Statistics are based on the number of changed lines, or alternatively
the number of matching revisions if the --changesets option is speci‐
fied.
Examples:
# display count of changed lines for every committer
hg churn -t '{author|email}'
# display daily activity graph
hg churn -f '%H' -s -c
# display activity of developers by month
hg churn -f '%Y-%m' -s -c
# display count of lines changed in every year
hg churn -f '%Y' -s
It is possible to map alternate email addresses to a main address by
providing a file using the following format:
<alias email> = <actual email>
Such a file may be specified with the --aliases option, otherwise a
.hgchurn file will be looked for in the working directory root.
Options:
-r, --rev
count rate for the specified revision or range
-d, --date
count rate for revisions matching date spec
-t, --template
template to group changesets (default: {author|email})
-f, --dateformat
strftime-compatible format for grouping by date
-c, --changesets
count rate by number of changesets
-s, --sort
sort by key (default: sort by count)
--diffstat
display added/removed lines separately
--aliases
file with email aliases
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
color
colorize output from some commands
This extension modifies the status and resolve commands to add color to
their output to reflect file status, the qseries command to add color
to reflect patch status (applied, unapplied, missing), and to
diff-related commands to highlight additions, removals, diff headers,
and trailing whitespace.
Other effects in addition to color, like bold and underlined text, are
also available. By default, the terminfo database is used to find the
terminal codes used to change color and effect. If terminfo is not
available, then effects are rendered with the ECMA-48 SGR control func‐
tion (aka ANSI escape codes).
Default effects may be overridden from your configuration file:
[color]
status.modified = blue bold underline red_background
status.added = green bold
status.removed = red bold blue_background
status.deleted = cyan bold underline
status.unknown = magenta bold underline
status.ignored = black bold
# 'none' turns off all effects
status.clean = none
status.copied = none
qseries.applied = blue bold underline
qseries.unapplied = black bold
qseries.missing = red bold
diff.diffline = bold
diff.extended = cyan bold
diff.file_a = red bold
diff.file_b = green bold
diff.hunk = magenta
diff.deleted = red
diff.inserted = green
diff.changed = white
diff.trailingwhitespace = bold red_background
resolve.unresolved = red bold
resolve.resolved = green bold
bookmarks.current = green
branches.active = none
branches.closed = black bold
branches.current = green
branches.inactive = none
tags.normal = green
tags.local = black bold
The available effects in terminfo mode are 'blink', 'bold', 'dim',
'inverse', 'invisible', 'italic', 'standout', and 'underline'; in
ECMA-48 mode, the options are 'bold', 'inverse', 'italic', and 'under‐
line'. How each is rendered depends on the terminal emulator. Some
may not be available for a given terminal type, and will be silently
ignored.
Note that on some systems, terminfo mode may cause problems when using
color with the pager extension and less -R. less with the -R option
will only display ECMA-48 color codes, and terminfo mode may sometimes
emit codes that less doesn't understand. You can work around this by
either using ansi mode (or auto mode), or by using less -r (which will
pass through all terminal control codes, not just color control codes).
Because there are only eight standard colors, this module allows you to
define color names for other color slots which might be available for
your terminal type, assuming terminfo mode. For instance:
color.brightblue = 12
color.pink = 207
color.orange = 202
to set 'brightblue' to color slot 12 (useful for 16 color terminals
that have brighter colors defined in the upper eight) and, 'pink' and
'orange' to colors in 256-color xterm's default color cube. These
defined colors may then be used as any of the pre-defined eight,
including appending '_background' to set the background to that color.
By default, the color extension will use ANSI mode (or win32 mode on
Windows) if it detects a terminal. To override auto mode (to enable
terminfo mode, for example), set the following configuration option:
[color]
mode = terminfo
Any value other than 'ansi', 'win32', 'terminfo', or 'auto' will dis‐
able color.

If no destination directory name is specified, it defaults to the base‐
name of the source with -hg appended. If the destination repository
doesn't exist, it will be created.
By default, all sources except Mercurial will use --branchsort. Mercu‐
rial uses --sourcesort to preserve original revision numbers order.
Sort modes have the following effects:
--branchsort
convert from parent to child revision when possible, which means
branches are usually converted one after the other. It generates
more compact repositories.
--datesort
sort revisions by date. Converted repositories have good-looking
changelogs but are often an order of magnitude larger than the
same ones generated by --branchsort.
--sourcesort
try to preserve source revisions order, only supported by Mercu‐
rial sources.
If REVMAP isn't given, it will be put in a default location
(<dest>/.hg/shamap by default). The REVMAP is a simple text file that
maps each source commit ID to the destination ID for that revision,
like so:
<source ID> <destination ID>
If the file doesn't exist, it's automatically created. It's updated on
each commit copied, so hg convert can be interrupted and can be run
repeatedly to copy new commits.
The authormap is a simple text file that maps each source commit author
to a destination commit author. It is handy for source SCMs that use
unix logins to identify authors (eg: CVS). One line per author mapping
and the line format is:
source author = destination author
Empty lines and lines starting with a # are ignored.
The filemap is a file that allows filtering and remapping of files and
directories. Each line can contain one of the following directives:
include path/to/file-or-dir
exclude path/to/file-or-dir
rename path/to/source path/to/destination
Comment lines start with #. A specified path matches if it equals the
full relative name of a file or one of its parent directories. The
include or exclude directive with the longest matching path applies, so
line order does not matter.
The include directive causes a file, or all files under a directory, to
be included in the destination repository, and the exclusion of all
other files and directories not explicitly included. The exclude direc‐
tive causes files or directories to be omitted. The rename directive
renames a file or directory if it is converted. To rename from a subdi‐
rectory into the root of the repository, use . as the path to rename
to.
The splicemap is a file that allows insertion of synthetic history,
letting you specify the parents of a revision. This is useful if you
want to e.g. give a Subversion merge two parents, or graft two discon‐
nected series of history together. Each entry contains a key, followed
by a space, followed by one or two comma-separated values:
key parent1, parent2
The key is the revision ID in the source revision control system whose
parents should be modified (same format as a key in .hg/shamap). The
values are the revision IDs (in either the source or destination revi‐
sion control system) that should be used as the new parents for that
node. For example, if you have merged "release-1.0" into "trunk", then
you should specify the revision on "trunk" as the first parent and the
one on the "release-1.0" branch as the second.
The branchmap is a file that allows you to rename a branch when it is
being brought in from whatever external repository. When used in con‐
junction with a splicemap, it allows for a powerful combination to help
fix even the most badly mismanaged repositories and turn them into
nicely structured Mercurial repositories. The branchmap contains lines
of the form:
original_branch_name new_branch_name
where "original_branch_name" is the name of the branch in the source
repository, and "new_branch_name" is the name of the branch is the des‐
tination repository. No whitespace is allowed in the branch names. This
can be used to (for instance) move code in one repository from
"default" to a named branch.
Mercurial Source
The Mercurial source recognizes the following configuration options,
which you can set on the command line with --config:
convert.hg.ignoreerrors
ignore integrity errors when reading. Use it to fix Mercurial
repositories with missing revlogs, by converting from and to
Mercurial. Default is False.
convert.hg.saverev
store original revision ID in changeset (forces target IDs to
change). It takes a boolean argument and defaults to False.
convert.hg.startrev
convert start revision and its descendants. It takes a hg revi‐
sion identifier and defaults to 0.
CVS Source
CVS source will use a sandbox (i.e. a checked-out copy) from CVS to
indicate the starting point of what will be converted. Direct access to
the repository files is not needed, unless of course the repository is
:local:. The conversion uses the top level directory in the sandbox to
find the CVS repository, and then uses CVS rlog commands to find files
to convert. This means that unless a filemap is given, all files under
the starting directory will be converted, and that any directory reor‐
ganization in the CVS sandbox is ignored.
The following options can be used with --config:
convert.cvsps.cache
Set to False to disable remote log caching, for testing and
debugging purposes. Default is True.
convert.cvsps.fuzz
Specify the maximum time (in seconds) that is allowed between
commits with identical user and log message in a single change‐
set. When very large files were checked in as part of a change‐
set then the default may not be long enough. The default is 60.
convert.cvsps.mergeto
Specify a regular expression to which commit log messages are
matched. If a match occurs, then the conversion process will
insert a dummy revision merging the branch on which this log
message occurs to the branch indicated in the regex. Default is
{{mergetobranch ([-\w]+)}}
convert.cvsps.mergefrom
Specify a regular expression to which commit log messages are
matched. If a match occurs, then the conversion process will add
the most recent revision on the branch indicated in the regex as
the second parent of the changeset. Default is {{mergefrombranch
([-\w]+)}}
hook.cvslog
Specify a Python function to be called at the end of gathering
the CVS log. The function is passed a list with the log entries,
and can modify the entries in-place, or add or delete them.
hook.cvschangesets
Specify a Python function to be called after the changesets are
calculated from the the CVS log. The function is passed a list
with the changeset entries, and can modify the changesets
in-place, or add or delete them.
An additional "debugcvsps" Mercurial command allows the builtin change‐
set merging code to be run without doing a conversion. Its parameters
and output are similar to that of cvsps 2.1. Please see the command
help for more details.
Subversion Source
Subversion source detects classical trunk/branches/tags layouts. By
default, the supplied svn://repo/path/ source URL is converted as a
single branch. If svn://repo/path/trunk exists it replaces the default
branch. If svn://repo/path/branches exists, its subdirectories are
listed as possible branches. If svn://repo/path/tags exists, it is
looked for tags referencing converted branches. Default trunk, branches
and tags values can be overridden with following options. Set them to
paths relative to the source URL, or leave them blank to disable auto
detection.
The following options can be set with --config:
convert.svn.branches
specify the directory containing branches. The default is
branches.
convert.svn.tags
specify the directory containing tags. The default is tags.
convert.svn.trunk
specify the name of the trunk branch. The default is trunk.
Source history can be retrieved starting at a specific revision,
instead of being integrally converted. Only single branch conversions
are supported.
convert.svn.startrev
specify start Subversion revision number. The default is 0.
Perforce Source
The Perforce (P4) importer can be given a p4 depot path or a client
specification as source. It will convert all files in the source to a
flat Mercurial repository, ignoring labels, branches and integrations.
Note that when a depot path is given you then usually should specify a
target directory, because otherwise the target may be named ...-hg.
It is possible to limit the amount of source history to be converted by
specifying an initial Perforce revision:
convert.p4.startrev
specify initial Perforce revision (a Perforce changelist num‐
ber).
Mercurial Destination
The following options are supported:
convert.hg.clonebranches
dispatch source branches in separate clones. The default is
False.
convert.hg.tagsbranch
branch name for tag revisions, defaults to default.
convert.hg.usebranchnames
preserve branch names. The default is True.
Options:
--authors
username mapping filename (DEPRECATED, use --authormap instead)
-s, --source-type
source repository type
-d, --dest-type
destination repository type
-r, --rev
import up to target revision REV
-A, --authormap
remap usernames using this file
--filemap
remap file names using contents of file
--splicemap
splice synthesized history into place
--branchmap
change branch names while converting
--branchsort
try to sort changesets by branches
--datesort
try to sort changesets by date
--sourcesort
preserve source changesets order
eol
automatically manage newlines in repository files
This extension allows you to manage the type of line endings (CRLF or
LF) that are used in the repository and in the local working directory.
That way you can get CRLF line endings on Windows and LF on Unix/Mac,
thereby letting everybody use their OS native line endings.
The extension reads its configuration from a versioned .hgeol configu‐
ration file found in the root of the working copy. The .hgeol file use
the same syntax as all other Mercurial configuration files. It uses two
sections, [patterns] and [repository].
The [patterns] section specifies how line endings should be converted
between the working copy and the repository. The format is specified by
a file pattern. The first match is used, so put more specific patterns
first. The available line endings are LF, CRLF, and BIN.
Files with the declared format of CRLF or LF are always checked out and
stored in the repository in that format and files declared to be binary
(BIN) are left unchanged. Additionally, native is an alias for checking
out in the platform's default line ending: LF on Unix (including Mac OS
X) and CRLF on Windows. Note that BIN (do nothing to line endings) is
Mercurial's default behaviour; it is only needed if you need to over‐
ride a later, more general pattern.
The optional [repository] section specifies the line endings to use for
files stored in the repository. It has a single setting, native, which
determines the storage line endings for files declared as native in the
[patterns] section. It can be set to LF or CRLF. The default is LF. For
example, this means that on Windows, files configured as native (CRLF
by default) will be converted to LF when stored in the repository.
Files declared as LF, CRLF, or BIN in the [patterns] section are always
stored as-is in the repository.
Example versioned .hgeol file:
[patterns]
**.py = native
**.vcproj = CRLF
**.txt = native
Makefile = LF
**.jpg = BIN
[repository]
native = LF
Note The rules will first apply when files are touched in the working
copy, e.g. by updating to null and back to tip to touch all
files.
The extension uses an optional [eol] section read from both the normal
Mercurial configuration files and the .hgeol file, with the latter
overriding the former. You can use that section to control the overall
behavior. There are three settings:
· eol.native (default os.linesep) can be set to LF or CRLF to override
the default interpretation of native for checkout. This can be used
with hg archive on Unix, say, to generate an archive where files have
line endings for Windows.
· eol.only-consistent (default True) can be set to False to make the
extension convert files with inconsistent EOLs. Inconsistent means
that there is both CRLF and LF present in the file. Such files are
normally not touched under the assumption that they have mixed EOLs
on purpose.
· eol.fix-trailing-newline (default False) can be set to True to ensure
that converted files end with a EOL character (either \n or \r\n as
per the configured patterns).
The extension provides cleverencode: and cleverdecode: filters like the
deprecated win32text extension does. This means that you can disable
win32text and enable eol and your filters will still work. You only
need to these filters until you have prepared a .hgeol file.
The win32text.forbid* hooks provided by the win32text extension have
been unified into a single hook named eol.checkheadshook. The hook will
lookup the expected line endings from the .hgeol file, which means you
must migrate to a .hgeol file first before using the hook. eol.check‐
headshook only checks heads, intermediate invalid revisions will be
pushed. To forbid them completely, use the eol.checkallhook hook. These
hooks are best used as pretxnchangegroup hooks.
See hg help patterns for more information about the glob patterns used.
extdiff
command to allow external programs to compare revisions
The extdiff Mercurial extension allows you to use external programs to
compare revisions, or revision with working directory. The external
diff programs are called with a configurable set of options and two
non-option arguments: paths to directories containing snapshots of
files to compare.
The extdiff extension also allows you to configure new diff commands,
so you do not need to type hg extdiff -p kdiff3 always.
[extdiff]
# add new command that runs GNU diff(1) in 'context diff' mode
cdiff = gdiff -Nprc5
## or the old way:
#cmd.cdiff = gdiff
#opts.cdiff = -Nprc5
# add new command called vdiff, runs kdiff3
vdiff = kdiff3
# add new command called meld, runs meld (no need to name twice)
meld =
# add new command called vimdiff, runs gvimdiff with DirDiff plugin
# (see http://www.vim.org/scripts/script.php?script_id=102) Non
# English user, be sure to put "let g:DirDiffDynamicDiffText = 1" in
# your .vimrc
vimdiff = gvim -f "+next" \
"+execute 'DirDiff' fnameescape(argv(0)) fnameescape(argv(1))"
Tool arguments can include variables that are expanded at runtime:
$parent1, $plabel1 - filename, descriptive label of first parent
$child, $clabel - filename, descriptive label of child revision
$parent2, $plabel2 - filename, descriptive label of second parent
$root - repository root
$parent is an alias for $parent1.
The extdiff extension will look in your [diff-tools] and [merge-tools]
sections for diff tool arguments, when none are specified in [extdiff].
[extdiff]
kdiff3 =
[diff-tools]
kdiff3.diffargs=--L1 '$plabel1' --L2 '$clabel' $parent $child
You can use -I/-X and list of file or directory names like normal hg
diff command. The extdiff extension makes snapshots of only needed
files, so running the external diff program will actually be pretty
fast (at least faster than having to compare the entire tree).
Commands
extdiff
hg extdiff [OPT]... [FILE]...
Show differences between revisions for the specified files, using an
external program. The default program used is diff, with default
options "-Npru".
To select a different program, use the -p/--program option. The program
will be passed the names of two directories to compare. To pass addi‐
tional options to the program, use -o/--option. These will be passed
before the names of the directories to compare.
When two revision arguments are given, then changes are shown between
those revisions. If only one revision is specified then that revision
is compared to the working directory, and, when no revisions are speci‐
fied, the working directory files are compared to its parent.
Options:
-p, --program
comparison program to run
-o, --option
pass option to comparison program
-r, --rev
revision
-c, --change
change made by revision
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
factotum
http authentication with factotum
This extension allows the factotum(4) facility on Plan 9 from Bell Labs
platforms to provide authentication information for HTTP access. Con‐
figuration entries specified in the auth section as well as authentica‐
tion information provided in the repository URL are fully supported. If
no prefix is specified, a value of "*" will be assumed.
By default, keys are specified as:
proto=pass service=hg prefix=<prefix> user=<username> !password=<password>
If the factotum extension is unable to read the required key, one will
be requested interactively.
A configuration section is available to customize runtime behavior. By
default, these entries are:
[factotum]
executable = /bin/auth/factotum
mountpoint = /mnt/factotum
service = hg
The executable entry defines the full path to the factotum binary. The
mountpoint entry defines the path to the factotum file service. Lastly,
the service entry controls the service name used when reading keys.
fetch
pull, update and merge in one command
Commands
fetch
hg fetch [SOURCE]
This finds all changes from the repository at the specified path or URL
and adds them to the local repository.
If the pulled changes add a new branch head, the head is automatically
merged, and the result of the merge is committed. Otherwise, the work‐
ing directory is updated to include the new changes.
When a merge is needed, the working directory is first updated to the
newly pulled changes. Local changes are then merged into the pulled
changes. To switch the merge order, use --switch-parent.
See hg help dates for a list of formats valid for -d/--date.
Returns 0 on success.
Options:
-r, --rev
a specific revision you would like to pull
-e, --edit
edit commit message
--force-editor

commands. When this options is given, an ASCII representation of the
revision graph is also shown.
Commands
glog
hg glog [OPTION]... [FILE]
Print a revision history alongside a revision graph drawn with ASCII
characters.
Nodes printed as an @ character are parents of the working directory.
Options:
-f, --follow

hgcia
hooks for integrating with the CIA.vc notification service
This is meant to be run as a changegroup or incoming hook. To configure
it, set the following options in your hgrc:
[cia]
# your registered CIA user name
user = foo
# the name of the project in CIA
project = foo
# the module (subproject) (optional)
#module = foo
# Append a diffstat to the log message (optional)
#diffstat = False
# Template to use for log messages (optional)
#template = {desc}\n{baseurl}{webroot}/rev/{node}-- {diffstat}
# Style to use (optional)
#style = foo
# The URL of the CIA notification service (optional)
# You can use mailto: URLs to send by email, eg
# mailto:cia@cia.vc
# Make sure to set email.from if you do this.
#url = http://cia.vc/
# print message instead of sending it (optional)
#test = False
# number of slashes to strip for url paths
#strip = 0
[hooks]
# one of these:
changegroup.cia = python:hgcia.hook
#incoming.cia = python:hgcia.hook
[web]
# If you want hyperlinks (optional)
baseurl = http://server/path/to/repo
hgk
browse the repository in a graphical way
The hgk extension allows browsing the history of a repository in a
graphical way. It requires Tcl/Tk version 8.4 or later. (Tcl/Tk is not
distributed with Mercurial.)
hgk consists of two parts: a Tcl script that does the displaying and
querying of information, and an extension to Mercurial named hgk.py,
which provides hooks for hgk to get information. hgk can be found in
the contrib directory, and the extension is shipped in the hgext repos‐
itory, and needs to be enabled.
The hg view command will launch the hgk Tcl script. For this command to
work, hgk must be in your search path. Alternately, you can specify the
path to hgk in your configuration file:
[hgk]
path=/location/of/hgk
hgk can make use of the extdiff extension to visualize revisions.
Assuming you had already configured extdiff vdiff command, just add:
[hgk]
vdiff=vdiff
Revisions context menu will now display additional entries to fire
vdiff on hovered and selected revisions.
Commands
view
hg view [-l LIMIT] [REVRANGE]
start interactive history viewer
Options:
-l, --limit
limit number of changes displayed
highlight
syntax highlighting for hgweb (requires Pygments)
It depends on the Pygments syntax highlighting library:
http://pygments.org/
There is a single configuration option:
[web]
pygments_style = <style>
The default is 'colorful'.
inotify
accelerate status report using Linux's inotify service
Commands
inserve
hg inserve [OPTION]...
start an inotify server for this repository
Options:
-d, --daemon
run server in background
--daemon-pipefds
used internally by daemon mode
-t, --idle-timeout
minutes to sit idle before exiting
--pid-file
name of file to write process ID to
interhg
expand expressions into changelog and summaries
This extension allows the use of a special syntax in summaries, which
will be automatically expanded into links or any other arbitrary
expression, much like InterWiki does.
A few example patterns (link to bug tracking, etc.) that may be used in
your hgrc:
[interhg]
issues = s!issue(\d+)!<a href="http://bts/issue\1">issue\1</a>!
bugzilla = s!((?:bug|b=|(?=#?\d{4,}))(?:\s*#?)(\d+))!<a..=\2">\1</a>!i
boldify = s!(^|\s)#(\d+)\b! <b>#\2</b>!
keyword
expand keywords in tracked files
This extension expands RCS/CVS-like or self-customized $Keywords$ in
tracked text files selected by your configuration.
Keywords are only expanded in local repositories and not stored in the
change history. The mechanism can be regarded as a convenience for the
current user or for archive distribution.
Keywords expand to the changeset data pertaining to the latest change
relative to the working directory parent of each file.
Configuration is done in the [keyword], [keywordset] and [keywordmaps]
sections of hgrc files.
Example:
[keyword]
# expand keywords in every python file except those matching "x*"
**.py =
x* = ignore
[keywordset]
# prefer svn- over cvs-like default keywordmaps
svn = True
Note The more specific you are in your filename patterns the less you
lose speed in huge repositories.
For [keywordmaps] template mapping and expansion demonstration and con‐
trol run hg kwdemo. See hg help templates for a list of available tem‐
plates and filters.
Three additional date template filters are provided:
utcdate
"2006/09/18 15:13:13"
svnutcdate
"2006-09-18 15:13:13Z"
svnisodate
"2006-09-18 08:13:13 -700 (Mon, 18 Sep 2006)"
The default template mappings (view with hg kwdemo -d) can be replaced
with customized keywords and templates. Again, run hg kwdemo to control
the results of your configuration changes.
Before changing/disabling active keywords, you must run hg kwshrink to
avoid storing expanded keywords in the change history.
To force expansion after enabling it, or a configuration change, run hg
kwexpand.
Expansions spanning more than one line and incremental expansions, like
CVS' $Log$, are not supported. A keyword template map "Log = {desc}"
expands to the first line of the changeset description.
Commands
kwdemo
hg kwdemo [-d] [-f RCFILE] [TEMPLATEMAP]...
Show current, custom, or default keyword template maps and their expan‐
sions.
Extend the current configuration by specifying maps as arguments and
using -f/--rcfile to source an external hgrc file.
Use -d/--default to disable current configuration.
See hg help templates for information on templates and filters.
Options:
-d, --default
show default keyword template maps
-f, --rcfile
read maps from rcfile
kwexpand
hg kwexpand [OPTION]... [FILE]...
Run after (re)enabling keyword expansion.
kwexpand refuses to run if given files contain local changes.
Options:
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
kwfiles
hg kwfiles [OPTION]... [FILE]...
List which files in the working directory are matched by the [keyword]
configuration patterns.
Useful to prevent inadvertent keyword expansion and to speed up execu‐
tion by including only files that are actual candidates for expansion.
See hg help keyword on how to construct patterns both for inclusion and
exclusion of files.
With -A/--all and -v/--verbose the codes used to show the status of
files are:
K = keyword expansion candidate
k = keyword expansion candidate (not tracked)
I = ignored
i = ignored (not tracked)
Options:
-A, --all
show keyword status flags of all files
-i, --ignore
show files excluded from expansion
-u, --unknown
only show unknown (not tracked) files
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
kwshrink
hg kwshrink [OPTION]... [FILE]...
Must be run before changing/disabling active keywords.
kwshrink refuses to run if given files contain local changes.
Options:
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
largefiles
track large binary files
Large binary files tend to be not very compressible, not very diffable,
and not at all mergeable. Such files are not handled efficiently by
Mercurial's storage format (revlog), which is based on compressed
binary deltas; storing large binary files as regular Mercurial files
wastes bandwidth and disk space and increases Mercurial's memory usage.
The largefiles extension addresses these problems by adding a central‐
ized client-server layer on top of Mercurial: largefiles live in a cen‐
tral store out on the network somewhere, and you only fetch the revi‐
sions that you need when you need them.
largefiles works by maintaining a "standin file" in .hglf/ for each
largefile. The standins are small (41 bytes: an SHA-1 hash plus new‐
line) and are tracked by Mercurial. Largefile revisions are identified
by the SHA-1 hash of their contents, which is written to the standin.
largefiles uses that revision ID to get/put largefile revisions from/to
the central store. This saves both disk space and bandwidth, since you
don't need to retrieve all historical revisions of large files when you
clone or pull.
To start a new repository or add new large binary files, just add
--large to your hg add command. For example:
$ dd if=/dev/urandom of=randomdata count=2000
$ hg add --large randomdata
$ hg commit -m 'add randomdata as a largefile'
When you push a changeset that adds/modifies largefiles to a remote
repository, its largefile revisions will be uploaded along with it.
Note that the remote Mercurial must also have the largefiles extension
enabled for this to work.
When you pull a changeset that affects largefiles from a remote reposi‐
tory, Mercurial behaves as normal. However, when you update to such a
revision, any largefiles needed by that revision are downloaded and
cached (if they have never been downloaded before). This means that
network access may be required to update to changesets you have not
previously updated to.
If you already have large files tracked by Mercurial without the large‐
files extension, you will need to convert your repository in order to
benefit from largefiles. This is done with the hg lfconvert command:
$ hg lfconvert --size 10 oldrepo newrepo
In repositories that already have largefiles in them, any new file over
10MB will automatically be added as a largefile. To change this thresh‐
old, set largefiles.minsize in your Mercurial config file to the mini‐
mum size in megabytes to track as a largefile, or use the --lfsize
option to the add command (also in megabytes):
[largefiles]
minsize = 2
$ hg add --lfsize 2
The largefiles.patterns config option allows you to specify a list of
filename patterns (see hg help patterns) that should always be tracked
as largefiles:
[largefiles]
patterns =
*.jpg
re:.*\.(png|bmp)$
library.zip
content/audio/*
Files that match one of these patterns will be added as largefiles
regardless of their size.
The largefiles.minsize and largefiles.patterns config options will be
ignored for any repositories not already containing a largefile. To add
the first largefile to a repository, you must explicitly do so with the
--large flag passed to the hg add command.
Commands
lfconvert
hg lfconvert SOURCE DEST [FILE ...]
Convert repository SOURCE to a new repository DEST, identical to SOURCE
except that certain files will be converted as largefiles: specifi‐
cally, any file that matches any PATTERN or whose size is above the
minimum size threshold is converted as a largefile. The size used to
determine whether or not to track a file as a largefile is the size of
the first version of the file. The minimum size can be specified either
with --size or in configuration as largefiles.size.
After running this command you will need to make sure that largefiles
is enabled anywhere you intend to push the new repository.
Use --to-normal to convert largefiles back to normal files; after this,
the DEST repository can be used without largefiles at all.
Options:
-s, --size
minimum size (MB) for files to be converted as largefiles
--to-normal
convert from a largefiles repo to a normal repo
mq
manage a stack of patches
This extension lets you work with a stack of patches in a Mercurial
repository. It manages two stacks of patches - all known patches, and
applied patches (subset of known patches).
Known patches are represented as patch files in the .hg/patches direc‐
tory. Applied patches are both patch files and changesets.
Common tasks (use hg help command for more details):
create new patch qnew
import existing patch qimport
print patch series qseries
print applied patches qapplied
add known patch to applied stack qpush
remove patch from applied stack qpop
refresh contents of top applied patch qrefresh
By default, mq will automatically use git patches when required to
avoid losing file mode changes, copy records, binary files or empty
files creations or deletions. This behaviour can be configured with:
[mq]
git = auto/keep/yes/no
If set to 'keep', mq will obey the [diff] section configuration while
preserving existing git patches upon qrefresh. If set to 'yes' or 'no',
mq will override the [diff] section and always generate git or regular
patches, possibly losing data in the second case.
It may be desirable for mq changesets to be kept in the secret phase
(see hg help phases), which can be enabled with the following setting:
[mq]
secret = True
You will by default be managing a patch queue named "patches". You can
create other, independent patch queues with the hg qqueue command.
Commands
qapplied
hg qapplied [-1] [-s] [PATCH]
Returns 0 on success.
Options:
-1, --last
show only the preceding applied patch
-s, --summary
print first line of patch header
qclone
hg qclone [OPTION]... SOURCE [DEST]
If source is local, destination will have no patches applied. If source
is remote, this command can not check if patches are applied in source,
so cannot guarantee that patches are not applied in destination. If you
clone remote repository, be sure before that it has no patches applied.
Source patch repository is looked for in <src>/.hg/patches by default.
Use -p <url> to change.
The patch directory must be a nested Mercurial repository, as would be
created by hg init --mq.
Return 0 on success.
Options:
--pull use pull protocol to copy metadata
-U, --noupdate
do not update the new working directories
--uncompressed
use uncompressed transfer (fast over LAN)
-p, --patches
location of source patch repository
-e, --ssh
specify ssh command to use
--remotecmd
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
qcommit
hg qcommit [OPTION]... [FILE]...
This command is deprecated; use hg commit --mq instead.
Options:
-A, --addremove
mark new/missing files as added/removed before committing
--close-branch
mark a branch as closed, hiding it from the branch list
--amend
amend the parent of the working dir
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-m, --message

-u, --user
record the specified user as committer
-S, --subrepos
recurse into subrepositories
aliases: qci
qdelete
hg qdelete [-k] [PATCH]...
The patches must not be applied, and at least one patch is required.
Exact patch identifiers must be given. With -k/--keep, the patch files
are preserved in the patch directory.
To stop managing a patch and move it into permanent history, use the hg
qfinish command.
Options:
-k, --keep
keep patch file
-r, --rev
stop managing a revision (DEPRECATED)
aliases: qremove qrm
qdiff
hg qdiff [OPTION]... [FILE]...
Shows a diff which includes the current patch as well as any changes
which have been made in the working directory since the last refresh
(thus showing what the current patch would become after a qrefresh).
Use hg diff if you only want to see the changes made since the last
qrefresh, or hg export qtip if you want to see changes made by the cur‐
rent patch without including changes made since the qrefresh.
Returns 0 on success.
Options:
-a, --text
treat all files as text
-g, --git
use git extended diff format
--nodates
omit dates from diff headers
-p, --show-function
show which function each change is in
--reverse
produce a diff that undoes the changes
-w, --ignore-all-space
ignore white space when comparing lines
-b, --ignore-space-change
ignore changes in the amount of white space
-B, --ignore-blank-lines
ignore changes whose lines are all blank
-U, --unified

--stat output diffstat-style summary of changes
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
qfinish
hg qfinish [-a] [REV]...
Finishes the specified revisions (corresponding to applied patches) by
moving them out of mq control into regular repository history.
Accepts a revision range or the -a/--applied option. If --applied is
specified, all applied mq revisions are removed from mq control. Other‐
wise, the given revisions must be at the base of the stack of applied
patches.
This can be especially useful if your changes have been applied to an
upstream repository, or if you are about to push your changes to
upstream.
Returns 0 on success.
Options:
-a, --applied
finish all applied changesets
qfold
hg qfold [-e] [-k] [-m TEXT] [-l FILE] PATCH...
Patches must not yet be applied. Each patch will be successively
applied to the current patch in the order given. If all the patches
apply successfully, the current patch will be refreshed with the new
cumulative patch, and the folded patches will be deleted. With
-k/--keep, the folded patch files will not be removed afterwards.
The header for each folded patch will be concatenated with the current
patch header, separated by a line of * * *.
Returns 0 on success.
Options:
-e, --edit
edit patch header
-k, --keep
keep folded patch files
-m, --message
use text as commit message
-l, --logfile
read commit message from file
qgoto
hg qgoto [OPTION]... PATCH
Returns 0 on success.
Options:
-f, --force
overwrite any local changes
--no-backup
do not save backup copies of files
qguard
hg qguard [-l] [-n] [PATCH] [-- [+GUARD]... [-GUARD]...]
Guards control whether a patch can be pushed. A patch with no guards is
always pushed. A patch with a positive guard ("+foo") is pushed only if
the hg qselect command has activated it. A patch with a negative guard
("-foo") is never pushed if the hg qselect command has activated it.
With no arguments, print the currently active guards. With arguments,
set guards for the named patch.
Note Specifying negative guards now requires '--'.
To set guards on another patch:
hg qguard other.patch -- +2.6.17 -stable
Returns 0 on success.
Options:
-l, --list
list all patches and guards
-n, --none
drop all guards
qheader
hg qheader [PATCH]
Returns 0 on success.
qimport
hg qimport [-e] [-n NAME] [-f] [-g] [-P] [-r REV]... FILE...
The patch is inserted into the series after the last applied patch. If
no patches have been applied, qimport prepends the patch to the series.
The patch will have the same name as its source file unless you give it
a new one with -n/--name.
You can register an existing patch inside the patch directory with the
-e/--existing flag.
With -f/--force, an existing patch of the same name will be overwrit‐
ten.
An existing changeset may be placed under mq control with -r/--rev
(e.g. qimport --rev tip -n patch will place tip under mq control).
With -g/--git, patches imported with --rev will use the git diff for‐
mat. See the diffs help topic for information on why this is important
for preserving rename/copy information and permission changes. Use hg
qfinish to remove changesets from mq control.
To import a patch from standard input, pass - as the patch file. When
importing from standard input, a patch name must be specified using the
--name flag.
To import an existing patch while renaming it:
hg qimport -e existing-patch -n new-name
Returns 0 if import succeeded.
Options:
-e, --existing
import file in patch directory
-n, --name
name of patch file
-f, --force
overwrite existing files
-r, --rev
place existing revisions under mq control
-g, --git
use git extended diff format
-P, --push
qpush after importing
qinit
hg qinit [-c]
The queue repository is unversioned by default. If -c/--create-repo is
specified, qinit will create a separate nested repository for patches
(qinit -c may also be run later to convert an unversioned patch reposi‐
tory into a versioned one). You can use qcommit to commit changes to
this queue repository.
This command is deprecated. Without -c, it's implied by other relevant
commands. With -c, use hg init --mq instead.
Options:
-c, --create-repo
create queue repository
qnew
hg qnew [-e] [-m TEXT] [-l FILE] PATCH [FILE]...
qnew creates a new patch on top of the currently-applied patch (if
any). The patch will be initialized with any outstanding changes in the
working directory. You may also use -I/--include, -X/--exclude, and/or
a list of files after the patch name to add only changes to matching
files to the new patch, leaving the rest as uncommitted modifications.
-u/--user and -d/--date can be used to set the (given) user and date,
respectively. -U/--currentuser and -D/--currentdate set user to current
user and date to current date.
-e/--edit, -m/--message or -l/--logfile set the patch header as well as
the commit message. If none is specified, the header is empty and the
commit message is '[mq]: PATCH'.
Use the -g/--git option to keep the patch in the git extended diff for‐
mat. Read the diffs help topic for more information on why this is
important for preserving permission changes and copy/rename informa‐
tion.
Returns 0 on successful creation of a new patch.
Options:
-e, --edit
edit commit message
-f, --force
import uncommitted changes (DEPRECATED)
-g, --git
use git extended diff format
-U, --currentuser
add "From: <current user>" to patch
-u, --user
add "From: <USER>" to patch
-D, --currentdate
add "Date: <current date>" to patch
-d, --date
add "Date: <DATE>" to patch
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-m, --message
use text as commit message
-l, --logfile
read commit message from file
qnext
hg qnext [-s]
Returns 0 on success.
Options:
-s, --summary
print first line of patch header
qpop
hg qpop [-a] [-f] [PATCH | INDEX]
By default, pops off the top of the patch stack. If given a patch name,
keeps popping off patches until the named patch is at the top of the
stack.
Return 0 on success.
Options:
-a, --all
pop all patches
-n, --name
queue name to pop (DEPRECATED)
-f, --force
forget any local changes to patched files
--no-backup
do not save backup copies of files
qprev
hg qprev [-s]
Returns 0 on success.
Options:
-s, --summary
print first line of patch header
qpush
hg qpush [-f] [-l] [-a] [--move] [PATCH | INDEX]
When -f/--force is applied, all local changes in patched files will be
lost.
Return 0 on success.
Options:
-f, --force
apply on top of local changes
-e, --exact
apply the target patch to its recorded parent
-l, --list
list patch name in commit text
-a, --all
apply all patches
-m, --merge
merge from another queue (DEPRECATED)
-n, --name
merge queue name (DEPRECATED)
--move reorder patch series and apply only the patch
--no-backup
do not save backup copies of files
qqueue
hg qqueue [OPTION] [QUEUE]
Supports switching between different patch queues, as well as creating
new patch queues and deleting existing ones.
Omitting a queue name or specifying -l/--list will show you the regis‐
tered queues - by default the "normal" patches queue is registered. The
currently active queue will be marked with "(active)". Specifying
--active will print only the name of the active queue.
To create a new queue, use -c/--create. The queue is automatically made
active, except in the case where there are applied patches from the
currently active queue in the repository. Then the queue will only be
created and switching will fail.
To delete an existing queue, use --delete. You cannot delete the cur‐
rently active queue.
Returns 0 on success.
Options:
-l, --list
list all available queues
--active
print name of active queue
-c, --create
create new queue
--rename
rename active queue
--delete
delete reference to queue
--purge
delete queue, and remove patch dir
qrefresh
hg qrefresh [-I] [-X] [-e] [-m TEXT] [-l FILE] [-s] [FILE]...
If any file patterns are provided, the refreshed patch will contain
only the modifications that match those patterns; the remaining modifi‐
cations will remain in the working directory.
If -s/--short is specified, files currently included in the patch will
be refreshed just like matched files and remain in the patch.
If -e/--edit is specified, Mercurial will start your configured editor
for you to enter a message. In case qrefresh fails, you will find a
backup of your message in .hg/last-message.txt.
hg add/remove/copy/rename work as usual, though you might want to use
git-style patches (-g/--git or [diff] git=1) to track copies and
renames. See the diffs help topic for more information on the git diff
format.
Returns 0 on success.
Options:
-e, --edit
edit commit message
-g, --git
use git extended diff format
-s, --short
refresh only files already in the patch and specified files
-U, --currentuser
add/update author field in patch with current user
-u, --user
add/update author field in patch with given user
-D, --currentdate
add/update date field in patch with current date
-d, --date
add/update date field in patch with given date
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-m, --message
use text as commit message
-l, --logfile
read commit message from file
qrename
hg qrename PATCH1 [PATCH2]
With one argument, renames the current patch to PATCH1. With two argu‐
ments, renames PATCH1 to PATCH2.
Returns 0 on success.
aliases: qmv
qrestore
hg qrestore [-d] [-u] REV
This command is deprecated, use hg rebase instead.
Options:
-d, --delete
delete save entry
-u, --update
update queue working directory
qsave
hg qsave [-m TEXT] [-l FILE] [-c] [-n NAME] [-e] [-f]
This command is deprecated, use hg rebase instead.
Options:
-c, --copy
copy patch directory
-n, --name
copy directory name
-e, --empty
clear queue status file
-f, --force
force copy
-m, --message
use text as commit message
-l, --logfile
read commit message from file
qselect
hg qselect [OPTION]... [GUARD]...
Use the hg qguard command to set or print guards on patch, then use
qselect to tell mq which guards to use. A patch will be pushed if it
has no guards or any positive guards match the currently selected
guard, but will not be pushed if any negative guards match the current
guard. For example:
qguard foo.patch -- -stable (negative guard)
qguard bar.patch +stable (positive guard)
qselect stable
This activates the "stable" guard. mq will skip foo.patch (because it
has a negative match) but push bar.patch (because it has a positive
match).
With no arguments, prints the currently active guards. With one argu‐
ment, sets the active guard.
Use -n/--none to deactivate guards (no other arguments needed). When
no guards are active, patches with positive guards are skipped and
patches with negative guards are pushed.
qselect can change the guards on applied patches. It does not pop
guarded patches by default. Use --pop to pop back to the last applied
patch that is not guarded. Use --reapply (which implies --pop) to push
back to the current patch afterwards, but skip guarded patches.
Use -s/--series to print a list of all guards in the series file (no
other arguments needed). Use -v for more information.
Returns 0 on success.
Options:
-n, --none
disable all guards
-s, --series
list all guards in series file
--pop pop to before first guarded applied patch
--reapply
pop, then reapply patches
qseries
hg qseries [-ms]
Returns 0 on success.
Options:
-m, --missing
print patches not in series
-s, --summary
print first line of patch header
qtop
hg qtop [-s]
Returns 0 on success.
Options:
-s, --summary
print first line of patch header
qunapplied
hg qunapplied [-1] [-s] [PATCH]
Returns 0 on success.
Options:
-1, --first
show only the first patch
-s, --summary
print first line of patch header
strip
hg strip [-k] [-f] [-n] REV...
The strip command removes the specified changesets and all their
descendants. If the working directory has uncommitted changes, the
operation is aborted unless the --force flag is supplied, in which case
changes will be discarded.
If a parent of the working directory is stripped, then the working
directory will automatically be updated to the most recent available
ancestor of the stripped parent after the operation completes.
Any stripped changesets are stored in .hg/strip-backup as a bundle (see
hg help bundle and hg help unbundle). They can be restored by running
hg unbundle .hg/strip-backup/BUNDLE, where BUNDLE is the bundle file
created by the strip. Note that the local revision numbers will in gen‐
eral be different after the restore.
Use the --no-backup option to discard the backup bundle once the opera‐
tion completes.
Strip is not a history-rewriting operation and can be used on change‐
sets in the public phase. But if the stripped changesets have been
pushed to a remote repository you will likely pull them again.
Return 0 on success.
Options:
-r, --rev
strip specified revision (optional, can specify revisions with‐
out this option)
-f, --force
force removal of changesets, discard uncommitted changes (no
backup)
-b, --backup
bundle only changesets with local revision number greater than
REV which are not descendants of REV (DEPRECATED)
--no-backup
no backups
--nobackup
no backups (DEPRECATED)
-n ignored (DEPRECATED)
-k, --keep
do not modify working copy during strip
notify
hooks for sending email push notifications
This extension implements hooks to send email notifications when
changesets are sent from or received by the local repository.
First, enable the extension as explained in hg help extensions, and
register the hook you want to run. incoming and changegroup hooks are
run when changesets are received, while outgoing hooks are for change‐
sets sent to another repository:
[hooks]
# one email for each incoming changeset
incoming.notify = python:hgext.notify.hook
# one email for all incoming changesets
changegroup.notify = python:hgext.notify.hook
# one email for all outgoing changesets
outgoing.notify = python:hgext.notify.hook
This registers the hooks. To enable notification, subscribers must be
assigned to repositories. The [usersubs] section maps multiple reposi‐
tories to a given recipient. The [reposubs] section maps multiple
recipients to a single repository:
[usersubs]
# key is subscriber email, value is a comma-separated list of repo glob
# patterns
user@host = pattern
[reposubs]
# key is glob pattern, value is a comma-separated list of subscriber
# emails
pattern = user@host
Glob patterns are matched against absolute path to repository root.
In order to place them under direct user management, [usersubs] and
[reposubs] sections may be placed in a separate hgrc file and incorpo‐
rated by reference:
[notify]
config = /path/to/subscriptionsfile
Notifications will not be sent until the notify.test value is set to
False; see below.
Notifications content can be tweaked with the following configuration
entries:
notify.test
If True, print messages to stdout instead of sending them.
Default: True.
notify.sources
Space-separated list of change sources. Notifications are acti‐
vated only when a changeset's source is in this list. Sources
may be:
serve
changesets received via http or ssh
pull
changesets received via hg pull
unbundle
changesets received via hg unbundle
push
changesets sent or received via hg push
bundle
changesets sent via hg unbundle
Default: serve.
notify.strip
Number of leading slashes to strip from url paths. By default,
notifications reference repositories with their absolute path.
notify.strip lets you turn them into relative paths. For exam‐
ple, notify.strip=3 will change /long/path/repository into
repository. Default: 0.
notify.domain
Default email domain for sender or recipients with no explicit
domain.
notify.style
Style file to use when formatting emails.
notify.template
Template to use when formatting emails.
notify.incoming
Template to use when run as an incoming hook, overriding
notify.template.
notify.outgoing
Template to use when run as an outgoing hook, overriding
notify.template.
notify.changegroup
Template to use when running as a changegroup hook, overriding
notify.template.
notify.maxdiff
Maximum number of diff lines to include in notification email.
Set to 0 to disable the diff, or -1 to include all of it.
Default: 300.
notify.maxsubject
Maximum number of characters in email's subject line. Default:
67.
notify.diffstat
Set to True to include a diffstat before diff content. Default:
True.
notify.merge
If True, send notifications for merge changesets. Default: True.
notify.mbox
If set, append mails to this mbox file instead of sending.
Default: None.
notify.fromauthor
If set, use the committer of the first changeset in a change‐
group for the "From" field of the notification mail. If not set,
take the user from the pushing repo. Default: False.
If set, the following entries will also be used to customize the noti‐
fications:
email.from
Email From address to use if none can be found in the generated
email content.
web.baseurl
Root repository URL to combine with repository paths when making
references. See also notify.strip.
pager
browse command output with an external pager
To set the pager that should be used, set the application variable:
[pager]
pager = less -FRSX
If no pager is set, the pager extensions uses the environment variable
$PAGER. If neither pager.pager, nor $PAGER is set, no pager is used.
You can disable the pager for certain commands by adding them to the
pager.ignore list:
[pager]
ignore = version, help, update
You can also enable the pager only for certain commands using
pager.attend. Below is the default list of commands to be paged:
[pager]
attend = annotate, cat, diff, export, glog, log, qdiff
Setting pager.attend to an empty value will cause all commands to be
paged.
If pager.attend is present, pager.ignore will be ignored.
To ignore global commands like hg version or hg help, you have to spec‐
ify them in your user configuration file.
The --pager=... option can also be used to control when the pager is
used. Use a boolean value like yes, no, on, off, or use auto for normal
behavior.
patchbomb
command to send changesets as (a series of) patch emails
The series is started off with a "[PATCH 0 of N]" introduction, which
describes the series as a whole.
Each patch email has a Subject line of "[PATCH M of N] ...", using the
first line of the changeset description as the subject text. The mes‐
sage contains two or three body parts:
· The changeset description.
· [Optional] The result of running diffstat on the patch.
· The patch itself, as generated by hg export.
Each message refers to the first in the series using the In-Reply-To
and References headers, so they will show up as a sequence in threaded
mail and news readers, and in mail archives.
To configure other defaults, add a section like this to your configura‐
tion file:
[email]
from = My Name <my@email>
to = recipient1, recipient2, ...
cc = cc1, cc2, ...
bcc = bcc1, bcc2, ...
reply-to = address1, address2, ...
Use [patchbomb] as configuration section name if you need to override
global [email] address settings.
Then you can use the hg email command to mail a series of changesets as
a patchbomb.
You can also either configure the method option in the email section to
be a sendmail compatible mailer or fill out the [smtp] section so that
the patchbomb extension can automatically send patchbombs directly from
the commandline. See the [email] and [smtp] sections in hgrc(5) for
details.
Commands
email
hg email [OPTION]... [DEST]...
By default, diffs are sent in the format generated by hg export, one
per message. The series starts with a "[PATCH 0 of N]" introduction,
which describes the series as a whole.
Each patch email has a Subject line of "[PATCH M of N] ...", using the
first line of the changeset description as the subject text. The mes‐
sage contains two or three parts. First, the changeset description.
With the -d/--diffstat option, if the diffstat program is installed,
the result of running diffstat on the patch is inserted.
Finally, the patch itself, as generated by hg export.
With the -d/--diffstat or -c/--confirm options, you will be presented
with a final summary of all messages and asked for confirmation before
the messages are sent.
By default the patch is included as text in the email body for easy
reviewing. Using the -a/--attach option will instead create an attach‐
ment for the patch. With -i/--inline an inline attachment will be cre‐
ated. You can include a patch both as text in the email body and as a
regular or an inline attachment by combining the -a/--attach or
-i/--inline with the --body option.
With -o/--outgoing, emails will be generated for patches not found in
the destination repository (or only those which are ancestors of the
specified revisions if any are provided)
With -b/--bundle, changesets are selected as for --outgoing, but a sin‐
gle email containing a binary Mercurial bundle as an attachment will be
sent.
With -m/--mbox, instead of previewing each patchbomb message in a pager
or sending the messages directly, it will create a UNIX mailbox file
with the patch emails. This mailbox file can be previewed with any mail
user agent which supports UNIX mbox files.
With -n/--test, all steps will run, but mail will not be sent. You
will be prompted for an email recipient address, a subject and an
introductory message describing the patches of your patchbomb. Then
when all is done, patchbomb messages are displayed. If the PAGER envi‐
ronment variable is set, your pager will be fired up once for each
patchbomb message, so you can verify everything is alright.
In case email sending fails, you will find a backup of your series
introductory message in .hg/last-email.txt.
Examples:
hg email -r 3000 # send patch 3000 only
hg email -r 3000 -r 3001 # send patches 3000 and 3001
hg email -r 3000:3005 # send patches 3000 through 3005
hg email 3000 # send patch 3000 (deprecated)
hg email -o # send all patches not in default
hg email -o DEST # send all patches not in DEST
hg email -o -r 3000 # send all ancestors of 3000 not in default
hg email -o -r 3000 DEST # send all ancestors of 3000 not in DEST

progress
show progress bars for some actions
This extension uses the progress information logged by hg commands to
draw progress bars that are as informative as possible. Some progress
bars only offer indeterminate information, while others have a definite
end point.
The following settings are available:
[progress]
delay = 3 # number of seconds (float) before showing the progress bar
changedelay = 1 # changedelay: minimum delay before showing a new topic.
# If set to less than 3 * refresh, that value will
# be used instead.
refresh = 0.1 # time in seconds between refreshes of the progress bar
format = topic bar number estimate # format of the progress bar
width = <none> # if set, the maximum width of the progress information
# (that is, min(width, term width) will be used)
clear-complete = True # clear the progress bar after it's done
disable = False # if true, don't show a progress bar
assume-tty = False # if true, ALWAYS show a progress bar, unless
# disable is given
Valid entries for the format field are topic, bar, number, unit, esti‐
mate, speed, and item. item defaults to the last 20 characters of the
item, but this can be changed by adding either -<num> which would take
the last num characters, or +<num> for the first num characters.
purge
command to delete untracked files from the working directory
Commands
purge
hg purge [OPTION]... [DIR]...
Delete files not known to Mercurial. This is useful to test local and
uncommitted changes in an otherwise-clean source tree.
This means that purge will delete:
· Unknown files: files marked with "?" by hg status
· Empty directories: in fact Mercurial ignores directories unless they
contain files under source control management
But it will leave untouched:
· Modified and unmodified tracked files
· Ignored files (unless --all is specified)
· New files added to the repository (with hg add)
If directories are given on the command line, only files in these
directories are considered.
Be careful with purge, as you could irreversibly delete some files you
forgot to add to the repository. If you only want to print the list of
files that this program would delete, use the --print option.
Options:
-a, --abort-on-err
abort if an error occurs
--all purge ignored files too
-p, --print
print filenames instead of deleting them
-0, --print0
end filenames with NUL, for use with xargs (implies -p/--print)
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
aliases: clean
rebase
command to move sets of revisions to a different ancestor
This extension lets you rebase changesets in an existing Mercurial
repository.
For more information: http://mercurial.selenic.com/wiki/RebaseExtension
Commands
rebase
hg rebase [-s REV | -b REV] [-d REV] [options]
hg rebase {-a|-c}
Rebase uses repeated merging to graft changesets from one part of his‐
tory (the source) onto another (the destination). This can be useful
for linearizing local changes relative to a master development tree.
You should not rebase changesets that have already been shared with
others. Doing so will force everybody else to perform the same rebase
or they will end up with duplicated changesets after pulling in your
rebased changesets.
If you don't specify a destination changeset (-d/--dest), rebase uses
the tipmost head of the current named branch as the destination. (The
destination changeset is not modified by rebasing, but new changesets
are added as its descendants.)
You can specify which changesets to rebase in two ways: as a "source"
changeset or as a "base" changeset. Both are shorthand for a topologi‐
cally related set of changesets (the "source branch"). If you specify
source (-s/--source), rebase will rebase that changeset and all of its
descendants onto dest. If you specify base (-b/--base), rebase will
select ancestors of base back to but not including the common ancestor
with dest. Thus, -b is less precise but more convenient than -s: you
can specify any changeset in the source branch, and rebase will select
the whole branch. If you specify neither -s nor -b, rebase uses the
parent of the working directory as the base.
By default, rebase recreates the changesets in the source branch as
descendants of dest and then destroys the originals. Use --keep to pre‐
serve the original source changesets. Some changesets in the source
branch (e.g. merges from the destination branch) may be dropped if they
no longer contribute any change.
One result of the rules for selecting the destination changeset and
source branch is that, unlike merge, rebase will do nothing if you are
at the latest (tipmost) head of a named branch with two heads. You need
to explicitly specify source and/or destination (or update to the other
head, if it's the head of the intended source branch).
If a rebase is interrupted to manually resolve a merge, it can be con‐
tinued with --continue/-c or aborted with --abort/-a.
Returns 0 on success, 1 if nothing to rebase.
Options:
-s, --source
rebase from the specified changeset
-b, --base
rebase from the base of the specified changeset (up to greatest
common ancestor of base and dest)
-r, --rev
rebase these revisions
-d, --dest
rebase onto the specified changeset
--collapse
collapse the rebased changesets
-m, --message
use text as collapse commit message
-e, --edit
invoke editor on commit messages
-l, --logfile
read collapse commit message from file
--keep keep original changesets
--keepbranches
keep original branch names
-D, --detach
force detaching of source from its original branch
-t, --tool
specify merge tool
-c, --continue
continue an interrupted rebase
-a, --abort
abort an interrupted rebase
--style
display using template map file
--template
display with template
record
commands to interactively select changes for commit/qrefresh
Commands
qrecord
hg qrecord [OPTION]... PATCH [FILE]...
See hg help qnew & hg help record for more information and usage.
record
hg record [OPTION]... [FILE]...
If a list of files is omitted, all changes reported by hg status will
be candidates for recording.
See hg help dates for a list of formats valid for -d/--date.
You will be prompted for whether to record changes to each modified
file, and for files with multiple changes, for each change to use. For
each query, the following responses are possible:
y - record this change
n - skip this change
e - edit this change manually
s - skip remaining changes to this file
f - record remaining changes to this file
d - done, skip remaining changes and files
a - record all changes to all remaining files
q - quit, recording no changes
? - display help
This command is not available when committing a merge.
Options:
-A, --addremove
mark new/missing files as added/removed before committing
--close-branch
mark a branch as closed, hiding it from the branch list
--amend
amend the parent of the working dir
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-m, --message
use text as commit message
-l, --logfile
read commit message from file
-d, --date
record the specified date as commit date
-u, --user
record the specified user as committer
-S, --subrepos
recurse into subrepositories
-w, --ignore-all-space
ignore white space when comparing lines
-b, --ignore-space-change
ignore changes in the amount of white space
-B, --ignore-blank-lines
ignore changes whose lines are all blank
relink
recreates hardlinks between repository clones
Commands
relink
hg relink [ORIGIN]
When repositories are cloned locally, their data files will be
hardlinked so that they only use the space of a single repository.
Unfortunately, subsequent pulls into either repository will break
hardlinks for any files touched by the new changesets, even if both
repositories end up pulling the same changes.
Similarly, passing --rev to "hg clone" will fail to use any hardlinks,
falling back to a complete copy of the source repository.
This command lets you recreate those hardlinks and reclaim that wasted
space.
This repository will be relinked to share space with ORIGIN, which must
be on the same local disk. If ORIGIN is omitted, looks for
"default-relink", then "default", in [paths].
Do not attempt any read operations on this repository while the command
is running. (Both repositories will be locked against writes.)
schemes
extend schemes with shortcuts to repository swarms
This extension allows you to specify shortcuts for parent URLs with a
lot of repositories to act like a scheme, for example:
[schemes]
py = http://code.python.org/hg/
After that you can use it like:
hg clone py://trunk/
Additionally there is support for some more complex schemas, for exam‐
ple used by Google Code:
[schemes]
gcode = http://{1}.googlecode.com/hg/
The syntax is taken from Mercurial templates, and you have unlimited
number of variables, starting with {1} and continuing with {2}, {3} and
so on. This variables will receive parts of URL supplied, split by /.
Anything not specified as {part} will be just appended to an URL.
For convenience, the extension adds these schemes by default:
[schemes]
py = http://hg.python.org/
bb = https://bitbucket.org/
bb+ssh = ssh://hg@bitbucket.org/
gcode = https://{1}.googlecode.com/hg/
kiln = https://{1}.kilnhg.com/Repo/
You can override a predefined scheme by defining a new scheme with the
same name.
share
share a common history between several working directories
Commands
share
hg share [-U] SOURCE [DEST]
Initialize a new repository and working directory that shares its his‐
tory with another repository.
Note using rollback or extensions that destroy/modify history (mq,
rebase, etc.) can cause considerable confusion with shared
clones. In particular, if two shared clones are both updated to
the same changeset, and one of them destroys that changeset with
rollback, the other clone will suddenly stop working: all opera‐
tions will fail with "abort: working directory has unknown par‐
ent". The only known workaround is to use debugsetparents on the
broken clone to reset it to a changeset that still exists (e.g.
tip).
Options:
-U, --noupdate
do not create a working copy
unshare
hg unshare
Copy the store data to the repo and remove the sharedpath data.
transplant
command to transplant changesets from another branch
This extension allows you to transplant patches from another branch.
Transplanted patches are recorded in .hg/transplant/transplants, as a
map from a changeset hash to its hash in the source repository.
Commands
transplant
hg transplant [-s REPO] [-b BRANCH [-a]] [-p REV] [-m REV] [REV]...
Selected changesets will be applied on top of the current working
directory with the log of the original changeset. The changesets are
copied and will thus appear twice in the history. Use the rebase exten‐
sion instead if you want to move a whole branch of unpublished change‐
sets.
If --log is specified, log messages will have a comment appended of the
form:
(transplanted from CHANGESETHASH)
You can rewrite the changelog message with the --filter option. Its
argument will be invoked with the current changelog message as $1 and
the patch as $2.
If --source/-s is specified, selects changesets from the named reposi‐
tory. If --branch/-b is specified, selects changesets from the branch
holding the named revision, up to that revision. If --all/-a is speci‐
fied, all changesets on the branch will be transplanted, otherwise you
will be prompted to select the changesets you want.
hg transplant --branch REVISION --all will transplant the selected
branch (up to the named revision) onto your current working directory.
You can optionally mark selected transplanted changesets as merge
changesets. You will not be prompted to transplant any ancestors of a
merged transplant, and you can merge descendants of them normally
instead of transplanting them.
Merge changesets may be transplanted directly by specifying the proper
parent changeset by calling hg transplant --parent.
If no merges or revisions are provided, hg transplant will start an
interactive changeset browser.
If a changeset application fails, you can fix the merge by hand and
then resume where you left off by calling hg transplant --continue/-c.
Options:
-s, --source
pull patches from REPO
-b, --branch
pull patches from branch BRANCH
-a, --all
pull all changesets up to BRANCH
-p, --prune
skip over REV
-m, --merge
merge at REV
--parent
parent to choose when transplanting merge
-e, --edit
invoke editor on commit messages
--log append transplant info to log message
-c, --continue
continue last transplant session after repair
--filter
filter changesets through command
win32mbcs
allow the use of MBCS paths with problematic encodings
Some MBCS encodings are not good for some path operations (i.e. split‐
ting path, case conversion, etc.) with its encoded bytes. We call such
a encoding (i.e. shift_jis and big5) as "problematic encoding". This
extension can be used to fix the issue with those encodings by wrapping
some functions to convert to Unicode string before path operation.
This extension is useful for:
· Japanese Windows users using shift_jis encoding.
· Chinese Windows users using big5 encoding.
· All users who use a repository with one of problematic encodings on
case-insensitive file system.
This extension is not needed for:
· Any user who use only ASCII chars in path.
· Any user who do not use any of problematic encodings.
Note that there are some limitations on using this extension:
· You should use single encoding in one repository.
· If the repository path ends with 0x5c, .hg/hgrc cannot be read.
· win32mbcs is not compatible with fixutf8 extension.
By default, win32mbcs uses encoding.encoding decided by Mercurial. You
can specify the encoding by config option:
[win32mbcs]
encoding = sjis
It is useful for the users who want to commit with UTF-8 log message.
win32text
perform automatic newline conversion
Deprecation: The win32text extension requires each user to configure
the extension again and again for each clone since the configuration
is not copied when cloning.
We have therefore made the eol as an alternative. The eol uses a
version controlled file for its configuration and each clone will
therefore use the right settings from the start.
To perform automatic newline conversion, use:
[extensions]
win32text =
[encode]
** = cleverencode:
# or ** = macencode:
[decode]
** = cleverdecode:
# or ** = macdecode:
If not doing conversion, to make sure you do not commit CRLF/CR by
accident:
[hooks]
pretxncommit.crlf = python:hgext.win32text.forbidcrlf
# or pretxncommit.cr = python:hgext.win32text.forbidcr
To do the same check on a server to prevent CRLF/CR from being pushed
or pulled:
[hooks]
pretxnchangegroup.crlf = python:hgext.win32text.forbidcrlf
# or pretxnchangegroup.cr = python:hgext.win32text.forbidcr
zeroconf
discover and advertise repositories on the local network
Zeroconf-enabled repositories will be announced in a network without
the need to configure a server or a service. They can be discovered
without knowing their actual IP address.
To allow other people to discover your repository using run hg serve in
your repository:
$ cd test
$ hg serve
You can discover Zeroconf-enabled repositories by running hg paths:
$ hg paths
zc-test = http://example.com:8000/test
FILES
/etc/mercurial/hgrc, $HOME/.hgrc, .hg/hgrc
This file contains defaults and configuration. Values in
.hg/hgrc override those in $HOME/.hgrc, and these override set‐
tings made in the global /etc/mercurial/hgrc configuration. See
hgrc(5) for details of the contents and format of these files.
.hgignore
This file contains regular expressions (one per line) that
describe file names that should be ignored by hg. For details,
see hgignore(5).
.hgsub
This file defines the locations of all subrepositories, and
tells where the subrepository checkouts came from. For details,
see hg help subrepos.
.hgsubstate
This file is where Mercurial stores all nested repository
states. NB: This file should not be edited manually.
.hgtags
This file contains changeset hash values and text tag names (one
of each separated by spaces) that correspond to tagged versions
of the repository contents. The file content is encoded using
UTF-8.
.hg/last-message.txt
This file is used by hg commit to store a backup of the commit
message in case the commit fails.
.hg/localtags
This file can be used to define local tags which are not shared
among repositories. The file format is the same as for .hgtags,
but it is encoded using the local system encoding.
Some commands (e.g. revert) produce backup files ending in .orig, if
the .orig file already exists and is not tracked by Mercurial, it will
be overwritten.
BUGS
Probably lots, please post them to the mailing list (see Resources
below) when you find them.
