GNU Source-highlight

GNU Source-highlight produces a document with syntax highlighting when given a source file.

Source-highlight reads source language specifications dynamically, thus it can be easily extended (without recompiling the sources) for handling new languages.

GNU Source-highlight also reads output format specifications dynamically, and thus it can be easily extended (without recompiling the sources) for handling new output formats. The syntax for these specifications is quite easy (take a look at the manual).

Since version 2.2, source-highlight can also generate cross references; in order to do this it relies on GNU Ctags.

These are the output formats already supported:

HTML
XHTML
LATEX
TEXINFO
ANSI color escape sequences (you can use this feature with less)

These are the input languages (or input formats) already supported (in alphabetical order):

C/C++
Bison
Caml
Changelog
Diff
Flex
Fortran
Html
Java
Javascript
Latex
Logtalk
Log files
Lua
ML
Pascal
Perl
PHP
Prolog
Python
Ruby
