1 = Syntax Coloring of Source Code =
|
|
|
2 Trac supports language-specific syntax highlighting of source code in [wiki:WikiFormatting wiki formatted] text and the [wiki:TracBrowser repository browser].
|
|
|
3
|
|
|
4 To do this, Trac uses external libraries with support for a great number of programming languages.
|
|
|
5
|
|
|
6 Currently Trac supports syntax coloring using one or more of the following packages:
|
|
|
7
|
|
|
8 * [http://people.ssh.fi/mtr/genscript/ GNU Enscript]
|
|
|
9 * [http://silvercity.sourceforge.net/ SilverCity]
|
|
|
10
|
|
|
11 To activate syntax coloring, simply install either one (or more) of these packages. No additional configuration is required, however to modify the colors, have a look at `trac/htdocs/css/code.css`.
|
|
|
12
|
|
|
13 When in use, Trac will automatically prioritize !SilverCity highlighting over Enscript if possible, (see note below).
|
|
|
14
|
|
|
15 If neither package is available, Trac will display the data as plain text.
|
|
|
16
|
|
|
17 '''Note:''' Enscript supports a greater number of languages, however !SilverCity is generally faster since it is a library and isn't executed in an external process.

19 === About SilverCity ===
|
|
|
20 !SilverCity uses the lexer from [http://www.scintilla.org/ Scintilla]. Scintilla supports more languages than !SilverCity implements. If you want to add a language to !SilverCity supported by Scintilla, it's not very difficult. See [http://projects.edgewall.com/trac/wiki/SilverCityAddLanguage SilverCityAddLanguage] for some information how.
