There were a few aims I wanted to meet: - Stick as closely as possible to the GLSL specification by using the reference grammar with minimal modification - Produce a haxe version of the parser so I could do some haxe-compile-time magic with it Haxe is fairly similar to javascript so I tried altering PEG.js to spit out haxe. The result was a 9000 line file which it turns out was too big to compile. ANTLR looked promising but it appeared to be a bit too much to work create a haxe port of the runtime. Lemon was minimalistic and had a simple syntax which was fairly close to the syntax of the reference grammar. The core parser is only about 300 lines[0] and everything else is in data tables[1] which are generated by the lemon command line tool.
