DESCRIPTION
Jed - programmers editor
Features:
Color syntax highlighting. Emulation of Emacs, EDT, Wordstar, and
Brief editors. Extensible in a language resembling C. Completely
customizable. Editing TeX files with AUC-TeX style editing (BiBTeX
support too). Folding support, and much more...
For complete documentation, see GNU info files, this manual only
provides brief tutorial.
OPTIONS
major options
--version
prints the version and compiletime variables.
--help
prints usage information.
--secure
runs Jed in secure mode, e.g. you can’t run any external
commands with system() or run_shell_cmd().
--batch
run Jed in batch mode. This is a non-interactive mode.
--script
this is a mode like --batch but jed does not eval the startup
files. It behaves like slsh. You must give the file that should
be evaluated as second argument. It’s the same as calling
jed-script.
minor options
-n
do not load .jedrc file.
-a file
load file as user configuration file instead of .jedrc.
+ n
goto line n in buffer (notice that in order to this option to
take effect, if must appear before the file name in the command
line, like ’jed +3 file’)
-g n
goto line n in buffer (notice that in order to this option to
take effect, if must appear after the file name in the command
line, like ’jed file -g 3’)
-l file
load file as S-Lang code.
-f function
execute S-Lang function named function
-s string
search forward for string
-2
split window
-i file
insert file into current buffer.
X options
xjed accapts the common options like -display, -name, -fn and
-geometry. Additionaly it accepts
-facesize SIZE, -fs SIZE
if build with XRENDERFONT support, selects the font size SIZE.
Use it with the option -fn to select a scalable font.
-foreground COLOR, -fg COLOR
sets the foreground color.
-background COLOR, -bg COLOR
sets the background color.
-fgMouse COLOR, -mfg COLOR
sets the foreground color of the mouse pointer.
-bgMouse COLOR, -mbg COLOR
sets the background color of the mouse pointer.
-Iconic, -ic
start iconified.
-title NAME
sets the window title to NAME.
For more options look at xterm.c.
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
emulation.
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
version number, the buffer name, mode, etc. Please beware of the
following 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-Lang interpreter.
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
evaluation 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
terminals function as well. Here, only the highlights are touched upon
(cut/paste operations are not considered ‘highlights’). In the
following, any character prefixed by the ^ character denotes a Control
character. 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
example, to move to the right 40 characters, one would press Esc 4 0
followed 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
Split Window.
Ctrl-X o
Other window.
Ctrl-X b
switch to buffer
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 .
Find tag
Ctrl-@
Set Mark (Begin defining a region). Used with a prefix argument
aborts the act of defining the region and pops the Mark.
FILES
JED_ROOT/lib/*.sl
these are the default runtime jed slang files (packages like
jed-extra can define additional slang library directories)
JED_ROOT/lib/site.sl
This is the default startup file.
/etc/jed.d/*.sl
The system wide configuration files (this is a special Debian
feature).
~/.jedrc
Per user configuration file, or
~/.jed/jed.rc
per user configuration file if the Jed_Home_Directory ~/.jed/
exists.
