== Editors ==

Various editors with various tools for programming, such as syntax highlighting, exist. This page lists some examples of editors and how to configure them.

'''This page is still under construction! If you feel something is missing or should be added please do so by yourself!'''

=== EMACS ===

To run ''emacs'' just enter
emacs [-nw]
in a terminal. Usually, this opens a new x-window. If you do not want to have a new window opened, you can run ''emacs'' with the -nw option (short for --no-window-system). In this case, the editor will have a simple, but fully functional interface in the terminal.

{| class="wikitable"
|Ctrl+X+C||quit ''jed''
|-
|Ctrl+X+S||save the current buffer into a file
|-
|Ctrl+G||cancel the current operation (e.g., entering commands)
|-
|Ctrl+Space||start/end region selection mode
|-
|Ctrl+W||cut region
|-
|Ctrl+Y||paste region
|-
|Alt+X||enter and execute ''emacs'' command(s)
|}

==== syntax highlighting in s-lang ====

''emacs'' does not have a build-in syntax highlighting for s-lang (''jed'' does!), but our good friends from MIT have written one: [[editors:slang-mode|slang-mode.el]]

Save the file at your preferred path and add the following lines to your .emacs file (that should automatically exist in your home directory).

(load "yourpreferredpath/slang-mode.el")

(autoload 'slang-mode "slang-mode"
"Mode for editing slang source files")
(setq auto-mode-alist
(append '(("\\.sl$" . slang-mode)) auto-mode-alist))

=== JED ===

In principle, ''jed'' is a clone of ''emacs'', written in [[isis:start|S-Lang]] by '''J'''ohn '''E'''. '''D'''avis. To run ''jed'', enter
jed
into a terminal. It is very easy to modify and extend, since you can define and run S-Lang functions to, e.g., apply a certain task to the current region, i.e., marked text.

==== Keyboard Shortcuts ====
Most of the ''emacs'' shortcuts and
|Alt+Shift+X|enter and execute S-Lang command(s)|
A list of intrinsic ''jed'' functions is found here: http://www.jedsoft.org/jed/doc/jedfuns.html

Note: the keys defining the shortcuts are give in some strange format, like "^X^C" for Ctrl+X+C. The string corresponds to the character send to the terminal. You can find out this string using
sed -n l
in a terminal. Try pressing Ctrl+X+C
==== Configuration ====
''jed'' can be configured via the .jedrc file in your home directory, which has to contain S-Lang commands only. Thus, user-defined functions can be implemented here. Customizing ''jed'' is controlled by variables. Here is an example of a simple .jedrc:
No_Backups = 1; % create no backups of edited files
DISPLAY_TIME = -1; % show time in 24h format in status bar
C_BRA_NEWLINE = 0; % 0 / 1 => doesn't start / starts a block in braces on a new line
C_BRACE = 0; % amount of space to indent brace
C_INDENT = 2; % indentation of blocks
HORIZONTAL_PAN = -1; % entire window will pan
LINENUMBERS = 2; % show line and column number in status bar
WRAP = 1<<31-1; % effectively disables wrapmode
WRAP_DEFAULT = 1<<31-1; % effectively disables wrapmode

% define additional keybindings
setkey("uncomment_region_or_line","^X:");

% define the color scheme to use
Color_Scheme_Path += ",/home/you/share/jed/color/"; % path to additional schemes
set_color_scheme("white-gm");

% define a useless function and bind it to Alt+1
public define useless() {
vmessage("this is useless");
}
local_setkey("useless", "^[1");

==== Color Scheme ====
In the above example, the user-defined color scheme ''white-gm'' is used. This is the S-Lang file ''white-gm.sl'' in the ''Color_Scheme_Path'':
% A color scheme for the terminal/console with white background
%
% Copyright (c) 2003 Günter Milde
% Released under the terms of the GNU General Public License (ver. 2 or later)
%
% This scheme uses only the basic color set, so it should work with all
% flavours of jed (tested with jed in rxvt and Linux console).
%
static variable bg = "white";

set_color("normal", "black", bg);
set_color("status", "yellow", "blue");
set_color("region", "yellow", "blue");
set_color("operator", "blue", bg); % +, -, etc..
set_color("number", "blue", bg); % 10, 2.71, etc..
set_color("comment", "magenta", bg);% /* comment */
set_color("string", "blue", bg); % "string" or 'char'
set_color("keyword", "blue", bg); % if, while, unsigned, ...
set_color("keyword1", "red", bg); % malloc, exit, etc...
set_color("delimiter", "blue", bg); % {}[](),.;...
set_color("preprocess", "green", bg);
set_color("message", "blue", bg);
set_color("error", "red", bg);
set_color("dollar", "red", bg);
set_color("...", "red", bg); % folding indicator

set_color ("menu_char", "yellow", "blue");
set_color ("menu", "white", "blue");
set_color ("menu_popup", "white", "blue");
set_color ("menu_shadow", "blue", "black");
set_color ("menu_selection", "white", "cyan");
