Syntax Coloring of Source Code
Trac supports language-specific syntax highlighting of source code in wiki formatted text and the repository browser.
To do this, Trac uses external libraries with support for a great number of programming languages.
Currently Trac supports syntax coloring using one or more of the following packages:
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
.
When in use, Trac will automatically prioritize SilverCity highlighting over Enscript if possible, (see note below).
If neither package is available, Trac will display the data as plain text.
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.
About SilverCity?
SilverCity uses the lexer from 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 SilverCityAddLanguage for some information how.
