The highlighting-kate is a syntax highlighting library for Haskell with
support for over 50 languages.  The syntax parsers are automatically
generated from Kate syntax descriptions [1], so any syntax supported by
Kate can be added.  An (optional) command-line program is provided,
along with a utility for generating new parsers from Kate XML syntax
descriptions.

Currently the following languages are supported: Ada, Asp, Awk, Bash,
Bibtex, C, Cmake, Coldfusion, Commonlisp, Cpp, Css, D, Djangotemplate,
Doxygen, Dtd, Eiffel, Erlang, Fortran, Haskell, Html, Java, Javadoc,
Javascript, Json, Latex, Lex, LiterateHaskell, Lua, Makefile, Matlab,
Mediawiki, Modula3, Nasm, Objectivec, Ocaml, Pascal, Perl, Php,
Postscript, Prolog, Python, Rhtml, Ruby, Scala, Scheme, Sgml, Sql,
SqlMysql, SqlPostgresql, Tcl, Texinfo, Xml, Xslt, Yacc.
