​SilverCity "is a lexing package, based on Scintilla, that can provide lexical analysis for over 20 programming and markup languages". Can be used for TracSyntaxColoring.

Version 0.9.7 recommended. Version 0.9.6 ​doesn't work with Trac.

Starting with Trac 0.11, we recommend using ​Pygments instead. SilverCity support has been dropped in Trac 0.13.
