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...
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
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:
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.
