03:30 idiosyncrat_ Just uploaded Marpa-R3-4.001_021 to CPAN
03:31 idiosyncrat_ It moves the memory management for Marpa recognizers from Perl to Lua.
03:31 idiosyncrat_ Next will be doing the same for Marpa grammars.
03:31 idiosyncrat_ This is all steps toward allowing a more flexible syntax in SLIF DSL files.
03:33 idiosyncrat_ Lua was needed because the hard part of new features is making sure the SLIF knows how to do the semantics for more complex types of rules.
03:33 idiosyncrat_ That is the rule
03:33 idiosyncrat_ A ::= B C* D
03:35 idiosyncrat_ really translates to A ::= B C_tmp D and C_tmp ::= C* and Marpa has to know how to put the results together, pretending they are one rule using the semantics indicated for
03:35 idiosyncrat_ A ::= B C* D
03:36 idiosyncrat_ This case could probably be hacking in without adding Lua semantics, but then making the next change would be even messier.
03:37 idiosyncrat_ Anyway, that's what's going on inside Marpa these days.
04:12 idiosyncrat_ CPANtesters results look good!

07:58 ronsavage JK: All tests passed here, although I did get a scary # of warnings. I guess you know about those.

15:16 Idiosyncrat Choroba's Karel talk, Marpa::R2 gets only a brief mention but the language is a nice example for Marpa
