DESCRIPTION
Jed - programmers editor
Features:
Color syntax highlighting. Emulation of Emacs, EDT, Wordstar, and
Brief editors. Extensible in a language resembling C. Completely cus‐
tomizable. Editing TeX files with AUC-TeX style editing (BiBTeX sup‐
port too). Folding support, and much more...
For complete documentation, see GNU info files, this manual only pro‐
vides brief tutorial.

-g 'n'
goto line n in buffer
-l 'file'
load file as S-Lang code.

-2
split window
-i 'file'
insert file into current buffer.
CONFIGURATION
Emulating Other Editors
JED's ability to create new functions using the S--Lang programming
language as well as allowing the user to choose key bindings, makes the
emulation of other editors possible. Currently, JED provides reasonable
emulation of the Emacs, EDT, and Wordstar editors.
Emacs Emulation
Emacs Emulation is provided by the S-Lang code in emacs.sl. The basic
functionality of Emacs is emulated; most Emacs users should have no
problem with JED. To enable Emacs emulation in JED, make sure that the
line:
() = evalfile ("emacs");
is in your jed.rc (.jedrc) startup file. JED is distributed with this
line already present in the default jed.rc file.
EDT Emulation
For EDT emulation, edt.sl must be loaded. This is accomplished by
ensuring that the line:
() = evalfile ("edt");
is in present in the jed.rc (.jedrc) Startup File.
Wordstar Emulation
wordstar.sl contains the S-Lang code for JED's Wordstar emulation.
Adding the line
() = evalfile ("wordstar");
to your jed.rc (.jedrc) startup file will enable JED's Wordstar emula‐
tion.
RUN TIME
Status line and Windows
JED supports multiple windows. Each window may contain the same buffer
or different buffers. A status line is displayed immediately below
each window. The status line contains information such as the JED ver‐
sion number, the buffer name, mode, etc. Please beware of the follow‐
ing indicators:
**
buffer has been modified since last save.
%%
buffer is read only.
m
Mark set indicator. This means a region is being defined.
d
File changed on disk indicator. This indicates that the file
associated with the buffer is newer than the buffer itself.
s
spot pushed indicator.
+
Undo is enabled for the buffer.
[Narrow]
Buffer is narrowed to a region of LINES.
[Macro]
A macro is being defined.
Mini-Buffer.
The Mini-Buffer consists of a single line located at the bottom of the
screen. Much of the dialog between the user and JED takes place in this
buffer. For example, when you search for a string, JED will prompt you
for the string in the Mini-Buffer.
The Mini-Buffer also provides a direct link to the S-Langinterpreter.
To access the interpreter, press Ctrl-X Esc and the S-Lang> prompt will
appear in the Mini-Buffer. Enter any valid S-Lang expression for eval‐
uation by the interpreter.
It is possible to recall data previously entered into the Mini-Buffer
by using the up and down arrow keys. This makes it possible to use and
edit previous expressions in a convenient and efficient manner.
Basic Editing
Editing with JED is pretty easy - most keys simply insert themselves.
Movement around the buffer is usually done using the arrow keys or page
up and page down keys. If edt.sl is loaded, the keypads on VTxxx ter‐
minals function as well. Here, only the highlights are touched upon
(cut/paste operations are not considered `highlights'). In the follow‐
ing, any character prefixed by the ^ character denotes a Control char‐
acter. On keyboards without an explicit Escape key, Ctrl-[ will most
likely generate and Escape character.
A prefix argument to a command may be generated by first hitting the
Esc key, then entering the number followed by pressing the desired key.
Normally, the prefix argument is used simply for repetition. For exam‐
ple, to move to the right 40 characters, one would press Esc 4 0 fol‐
lowed immediately by the right arrow key. This illustrates the use of
the repeat argument for repetition. However, the prefix argument may
be used in other ways as well. For example, to begin defining a
region, one would press the Ctrl-@ key. This sets the mark and begins
highlighting. Pressing the Ctrl-@ key with a prefix argument will
abort the act of defining the region and to pop the mark.
The following list of useful keybindings assumes that emacs.sl has been
loaded.
Ctrl-L
Redraw screen.
Ctrl-_
Undo (Control-underscore, also Ctrl-X u').
Esc q
Reformat paragraph (wrap mode). Used with a prefix argument.
will justify the paragraph as well.
Esc n
narrow paragraph (wrap mode). Used with a prefix argument will
justify the paragraph as well.
Esc ;
Make Language comment (Fortran and C)
Esc \
Trim whitespace around point
Esc !
Execute shell command
Esc $
Ispell word
Ctrl-X ?
Show line/column information.
`
quoted_insert --- insert next char as is (backquote key)
Esc s
Center line.
Esc u
Upcase word.
Esc d
Downcase word.
Esc c
Capitalize word.
Esc x
Get M-x minibuffer prompt with command completion
Ctrl-X Ctrl-B
pop up a list of buffers
Ctrl-X Ctrl-C
exit JED
Ctrl-X 0
Delete Current Window
Ctrl-X 1
One Window.
Ctrl-X 2

Ctrl-X o
Other window.
Ctrl-X b

Ctrl-X k
kill buffer
Ctrl-X s
save some buffers
Ctrl-X Esc
Get "S-Lang>" prompt for interface to the S-Lang interpreter.
Esc .

Ctrl-@
Set Mark (Begin defining a region). Used with a prefix argument
aborts the act of defining the region and pops the Mark.
