[antlr-interest] grammar to latex

[Ana Nelson]

Okay, I think I've worked out the last few kinks in the pygments
grammar. Examples are (temporarily) here:

http://ananelson.com/tmp/antlr-actionscript/
http://ananelson.com/tmp/antlr-c/
http://ananelson.com/tmp/antlr-csharp/
http://ananelson.com/tmp/antlr-java/
http://ananelson.com/tmp/antlr-python/

If you have any valid ANTLR v3 grammars that you think might be useful
test grammars, especially ones with a different target language,
please send them on to me, or if you prefer you can run pygments
yourself. My grammar is here with basic installation instructions:
http://pastie.org/223723

I did decide to just limit the grammar to ANTLR v3 for simplicity's
sake. Sorry if this puts anyone out but if anyone else wants to add v2
support it shouldn't be that hard, I won't get to it anytime soon
though.

While I was working on this, I came across a Ruby syntax highlighter
called Ultraviolet which, by virtue of the fact that it uses TextMate
bundles, also has ANTLR support:
http://ultraviolet.rubyforge.org/

I haven't used Ultraviolet so I can't give any useful comparisons.


A few of the C Sharp grammars do have 1 error in them, in lines such as this:

@header {
    #pragma warning disable 0219
}

The # before pragma is showing up as an error. Maybe someone can tell
me, is that valid C sharp? If so then I think the C Sharp grammar
might need a tweak.
