= Syntax Coloring of Source Code =
Trac supports language-specific colorization (syntax highlighting) of source code in [wiki:WikiFormatting WikiFormatted] text and the [wiki:TracBrowser Source Browser].

To perform this, Trac relies on external software packages with support for a great number of programming languages.

Currently Trac supports syntax coloring using [http://people.ssh.fi/mtr/genscript/ GNU Enscript] and [http://silvercity.sourceforge.net/ SilverCity]. 

'''To activate syntax coloring, simply install !SilverCity and/or Enscript.'''

Trac will automatically prioritize using !SilverCity before Enscript if possible. If neither 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, not having to execute an external process.''
[[br]]'''Note:''' ''Syntax Coloring is only available on trac >= 0.7.''
