Pluggable grammars #23

Open xsawyerx opened 4 years ago

xsawyerx commented 4 years ago

We can support grammar plugins so people could load additional grammar to parse DSLs.

Examples:

We can document the base lexemes so others can use them. They could create their own lexemes with a prefix for them, like MooseKeywordHasExpr and MooseKeywordHas.

Support from the wonderful #marpa developer community: :heart_eyes:

05:45 | jdurand_ | as stated by Jeffrey, I it just a matter of compiling a grammar using variables
05:45 | jdurand_ | https://github.com/jddurand/MarpaX-Languages-M4/blob/master/lib/MarpaX/Languages/M4/Impl/Parser.pm does that for example
05:47 | jdurand_ | when https://github.com/jddurand/perl-MarpaX-ESLIF-URI  is playing with grammar subclass, as it if was a object (the later is  using MarpaX::ESLIF and not Marpa::R2 directly but the principles are  the same)
