.SH DESCRIPTION
.LP
Mcedit is a link to
.B mc,
the Midnight Commander, forcing it
to immediately start its internal editor. The editor is a terminal
version of the
.B cooledit
standalone X Window editor.
.\".\"DONT_SPLIT"
mcedit is a link to
.BR mc ,
the main GNU Midnight Commander executable. Executing GNU Midnight
Commander under this name requests staring the internal editor and
opening the
.I file
specified on the command line. The editor is based on the terminal
version of
.B cooledit

.SH FEATURES
The internal file editor provides most of the features of common full
screen editors. It has an extendable file size limit of sixteen megabytes
and edits binary files flawlessly. The features it presently supports
are: Block copy, move, delete, cut, paste;
.I "key for key undo";
pull-down
menus; file insertion; macro definition; regular expression
search and replace (and our own scanf-printf search and
replace); shift-arrow MSW-MAC text highlighting (for the
linux console only); insert-overwrite toggle; word-wrap;
a variety of tabbing options; syntax highlighting for
various file types; and an option
to pipe text blocks through shell commands like indent and
ispell.

To see what keys do what, just consult the appropriate
pull-down menu. Other keys are: Shift movement

deletes highlighted text - all linux console only. Mouse highlighting
also works, and you can override the mouse as usual by holding down
the shift key while dragging the mouse to let normal terminal mouse
highlighting work.

.SH SYNTAX HIGHLIGHTING
As of version 3.6.0, \fBcooledit\fP has syntax highlighting. This means
that keywords and contexts (like C comments, string constants, etc)
are highlighted in different colors. The following section explains
the format of the file \fB~/.mc/cedit/Syntax\fP.
The file \fB~/.mc/cedit/Syntax\fP is rescanned on opening of a any new
editor file. The file contains rules for highlighting, each of which is
given on a separate line, and define which keywords will be highlighted
to what color. The file is also divided into sections, each beginning
with a line with the \fBfile\fP command, followed by a regular
expression. The regular expression dictates the file name that that set
of rules applies to. Following this is a description to be printed on the
left of the editor window explaining the file type to the user. A third
optional argument is a regular expression to match the first line of
text of the file. If either the file name matches, or the first line of text,
then those rules will be loaded.

A section ends with the start of a new section. Each section is divided
into contexts, and each context contains rules. A context is a scope
within the text that a particular set of rules belongs to. For instance,
the region within a C style comment (i.e. between \fB/*\fP and \fB*/\fP)
the region within a C style comment (i.e. between
.B /*
and
.BR */ )
has its own color. This is a context, although it will have no further
rules inside it because there is probably nothing that we want
highlighted within a C comment.
