[antlr-interest] Building syntax highlighters with ANTLR

[Sam Harwell]

I've made a few posts about this in the past, and it looks like another
one is on the way. I designed a new, much easier, robust, and general
way to make a syntax highlighter from a grammar, and it even allows
clean "stacking" of lexers. As a quick example, my primary grammar
recognizes a block comment, but it doesn't recognize Doxygen syntax
within that comment. By stacking a Doxygen-style fragment lexer in the
colorizer, and telling it to post-process any token of primary type
"DOC_COMMENT", I ended up with this.

 

I'd give the gory details now, but it's 3:30am - just had to share
because figuring this out is what kept me up! I can't wait to see
multi-level lexer stacking for my StringTemplate highlighter. J
