= 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]. 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://people.ssh.fi/mtr/genscript/ GNU Enscript] * [http://silvercity.sourceforge.net/ SilverCity] 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 [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. == Syntax Coloring Support == || || !SilverCity || Enscript || || Ada || || X || || Asm || || X || || * ASP || X || X || || * C || X || X || || * C++ || X || X || || * Java || || X || || Awk || || X || || CSS || X || || || Diff || || X || || Eiffel || || X || || Elisp || || X || || Fortran || || X || || Haskell || || X || || HTML || X || X || || IDL || || X || || Javascript || X || X || || m4 || || X || || Makefile || || X || || Matlab || || X || || Objective-C|| || X || || Pascal || || X || || * Perl || X || X || || * PHP || X || X || || PSP || X || || || Pyrex || || X || || * Python || X || X || || * Ruby || X || X (1) || || Scheme || || X || || Shell || || X || || SQL || X || X || || Troff || || X || || TCL || || X || || Tex || || X || || Verilog || || X || || VHDL || || X || || Visual Basic |||| X || || VRML || || X || || XML || X || X || ''(*) Supported as inline code blocks in [wiki:WikiFormatting Wiki text] using WikiProcessors.''
