provides brief tutorial.
OPTIONS
-batch
run Jed in batch mode.
This is a non-interactive mode.
-n
-g 'n'
-l 'file'
load
file
as S-Lang code.
-f 'function'
execute S-Lang function named
function
-s 'string'
search forward for
string
-2
-i 'file'
insert
file
into current buffer.
CONFIGURATION
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
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:
is in your
jed.rc
(.jedrc) startup file. JED is distributed
with this line already present in the default jed.rc file.
For
EDT
emulation,
edt.sl
must be loaded. This is accomplished by
ensuring that the line:
is in present in the jed.rc (.jedrc) Startup File.
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
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.
%%
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
+
Undo is enabled for the buffer.
[Narrow]
Buffer is narrowed to a region of LINES.
[Macro]
A macro is being defined.
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
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.
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
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 !
Esc $
Ctrl-X ?
Show line/column information.
`
quoted_insert --- insert
next char as is (backquote key)
Esc s
Esc u
Esc d
Esc c
Esc x
Get M-x minibuffer prompt with command
completion
Ctrl-X Ctrl-B
Ctrl-X Ctrl-C
Ctrl-X 0
Ctrl-X 1
Ctrl-X 2
Ctrl-X b
Ctrl-X k
Ctrl-X s
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.
