 = Syntax Coloring of Source Code =
 Trac supports language-specific syntax highlighting of source code in [wiki:WikiFormatting wiki formatted] text and the [wiki:TracBrowser repository browser].
+Trac supports language-specific syntax highlighting of source code within wiki formatted text in [WikiProcessors#CodeHighlightingSupport wiki processors] blocks and in the [TracBrowser 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:
+ * [http://www.codento.com/people/mtr/genscript/ GNU Enscript]
+ * [http://silvercity.sourceforge.net/ SilverCity]
+ * [http://pygments.pocoo.org/ Pygments], by far the preferred system, as it covers a wide range of programming languages and other structured texts and is actively supported
+ * [http://www.codento.com/people/mtr/genscript/ GNU Enscript], commonly available on Unix but somewhat unsupported on Windows
+ * [http://silvercity.sourceforge.net/ SilverCity], legacy system, some versions can be [http://trac.edgewall.org/wiki/TracFaq#why-is-my-css-code-not-being-highlighted-even-though-i-have-silvercity-installed problematic]
-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).
+To activate syntax coloring, simply install either one (or more) of these packages (see [#ExtraSoftware] section below).
+If none of these packages is available, Trac will display the data as plain text.
-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 Pygments ===
+=== About SilverCity ===
+!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.
+Starting with trac 0.11 [http://pygments.org/ pygments] will be the new default highlighter. It's a highlighting library implemented in pure python, very fast, easy to extend and [http://pygments.org/docs/ well documented].
+The Pygments default style can specified in the [TracIni#mimeviewer-section mime-viewer] section of trac.ini. The default style can be overridden by setting a Style preference on the [/prefs/pygments preferences page].
+It's very likely that the list below is outdated because the list of supported pygments lexers is growing weekly. Just have a look at the page of [http://pygments.org/docs/lexers/ supported lexers] on the pygments webpage.
