[antlr-interest] Guidelines for a antlr parser

[Jose Ventura]

Hi all,

I want to ask a question to the community to get your opinion.

I'm working in some parsers, these parsers have commons parts. I say,


Parser 1:   A B C D E
Parser 2:   F B D

    - every letter is a set of rules
      - every parser must build an AST with all tokens of all letters

Can be good to develop two parser, the first with 5 multilexer parsers and
the second with 3 multilexer parsers or it's better to develop without
multilexer?

Can I have performance problems with multilexer?

Thanks in advance,
José Ventura
