Last time I wrote a parser, I used yacc/bison. It wasn't particularly difficult to use, although I never stress-tested the language I put together. Anyway, the field of parser generators seems to have grown recently. I had never heard of ANTLR before, nor Lemon. Thanks for the pointers in this thread, I'll be sure to investigate them. There is also Parsec (for Haskell), and ocamllex and ocamlyacc (for OCaml). If you use C++, look into Boost.Spirit. I use tinyjson in production, which uses Boost.Spirit and it works quite well.
