PH-Highlight is a script written in Javascript for pretty-printing source code on Web pages. It is designed to be easy to use and lightweight, while not relying on separate CSS files (since certain hosts disallow this). It supports six languages (C, Java, Python, Perl, Haskell, and Javascript), and adding more is easy. It features the addition of colors to code, the ability to expand and collapse code, and the ability to open it in a popup window. Planned functionality includes line numbering, the ability to save the pre-colored source on disk (if some technical issues are resolved), and support for source located on a remote server.
