File::Spec::VMS(3pm) Perl Programmers Reference Guide File::Spec::VMS(3pm)NAMEFile::Spec::VMS - methods for VMS file specs
SYNOPSIS
require File::Spec::VMS; # Done internally by File::Spec if needed
DESCRIPTION
See File::Spec::Unix for a documentation of the methods provided there.
This package overrides the implementation of these methods, not the
semantics.
The default behavior is to allow either VMS or Unix syntax on input and
to return VMS syntax on output, even when Unix syntax was given on
input.
When used with a Perl of version 5.10 or greater and a CRTL possessing
the relevant capabilities, override behavior depends on the CRTL
features "DECC$FILENAME_UNIX_REPORT" and "DECC$EFS_CHARSET". When the
"DECC$EFS_CHARSET" feature is enabled and the input parameters are
clearly in Unix syntax, the output will be in Unix syntax. If
"DECC$FILENAME_UNIX_REPORT" is enabled and the output syntax cannot be
determined from the input syntax, the output will be in Unix syntax.
canonpath (override)
Removes redundant portions of file specifications according to the
syntax detected.
catdir (override)
Concatenates a list of file specifications, and returns the result
as a directory specification. No check is made for "impossible"
cases (e.g. elements other than the first being absolute
filespecs).
catfile (override)
Concatenates a list of directory specifications with a filename
specification to build a path.
curdir (override)
Returns a string representation of the current directory: '[]' or
'.'
devnull (override)
Returns a string representation of the null device: '_NLA0:' or
'/dev/null'
rootdir (override)
Returns a string representation of the root directory:
'SYS$DISK:[000000]' or '/'
tmpdir (override)
Returns a string representation of the first writable directory
from the following list or '' if none are writable:
/tmp if C<DECC$FILENAME_UNIX_REPORT> is enabled.
sys$scratch:
$ENV{TMPDIR}
Since perl 5.8.0, if running under taint mode, and if $ENV{TMPDIR}
is tainted, it is not used.
updir (override)
Returns a string representation of the parent directory: '[-]' or
'..'
case_tolerant (override)
VMS file specification syntax is case-tolerant.
path (override)
Translate logical name DCL$PATH as a searchlist, rather than trying
to "split" string value of $ENV{'PATH'}.
file_name_is_absolute (override)
Checks for VMS directory spec as well as Unix separators.
splitpath (override)
($volume,$directories,$file) = File::Spec->splitpath( $path );
($volume,$directories,$file) = File::Spec->splitpath( $path, $no_file );
Passing a true value for $no_file indicates that the path being
split only contains directory components, even on systems where you
can usually (when not supporting a foreign syntax) tell the
difference between directories and files at a glance.
splitdir (override)
Split a directory specification into the components.
catpath (override)
Construct a complete filespec.
abs2rel (override)
Attempt to convert a file specification to a relative
specification. On a system with volumes, like VMS, this may not be
possible.
rel2abs (override)
Return an absolute file specification from a relative one.
