.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.

It is advisable to use this feature with Prompt On Replace on, because
|
||||
a match is thought to be found whenever the number of arguments found
|
||||
matches the number given, which is not always a real match. Scanf also

||||
treats whitespace as being elastic. Note that the scanf format %[ is
|
||||
very useful for scanning strings, and whitespace.
