Subject: | Re: [Caml-list] Custom lexer in Camlp4 |
Excerpts from Jeremy Yallop's message of Tue Jun 24 15:03:19 +0200 2008: > Is there a way to replace the default lexer in Camlp4? I'd like to use > (an extended version of) one of the OCaml grammars, but with a different > lexer. You can rebuild (I mean functor application), your own camlp4 by giving another Lexer module. Basically you will have to copy/paste the short Camlp4.PreCast module (or a part of), by substituting Camlp4.Struct.Lexer by your Lexer implementation. That's fairly heavy but works.
