Chroma takes source code and other structured text and converts it into syntax highlighted HTML, ANSI-coloured text, and more.
Chroma is based heavily on Pygments, and includes translators for Pygments lexers and styles. Chroma, like Pygments, has the concepts of lexers, formatters and styles.
Lexers convert source text into a stream of tokens, styles specify how token types are mapped to colours, and formatters convert tokens and styles into formatted output.
A package exists for each of these, containing a global Registry variable with all of the registered implementations. There are also helper functions for using the registry in each package, such as looking up lexers by name or matching filenames, etc.
This is free and open source software.
