TracSyntaxColoring

-              v46
+              v47
+** Note: this page documents the 0.12 version of Trac, see [[0.11/TracSyntaxColoring]] if you need the previous version **
 = 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] (but needs a plugin for 0.10, see [#AboutPygments below])
+ * [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`.
+If you don't know why trac isnt detecting an installed library, try turning on Trac logging. It actually appears that Trac is broken with !SilverCity 0.9.6. Either use the current 0.9.7 or the older 0.9.5 http://trac.edgewall.org/wiki/TracFaq#why-is-my-css-code-not-being-highlighted-even-though-i-have-silvercity-installed
+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.
-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 [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://trac.edgewall.org/wiki/SilverCityAddLanguage SilverCityAddLanguage] for some information how.
 === About Pygments ===
 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]. While it does not support as many languages as Enscript or Scintilla the overall output quality is much better.

+To use pygments in trac 0.11 you just have to install pygments 0.6 or higher.  If you want to use it in trac 0.10 too you have to install the [th:TracPygmentsPlugin TracPygmentsPlugin] from trac hacks. If you encounter any bugs, please file tickets regarding Pygments at [http://dev.pocoo.org/projects/pygments/ the Pygments Trac site].
+The Pygments default style can specified in the [TracIni#mimeviewer-section mime-viewer] section of trac.ini. The default style can be over-ridden 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.
