03:42 idiosyncrat_ Just uploaded Marpa-R3-4.001_019
03:43 idiosyncrat_ With this, the SLIF semantics are now powered by a Lua engine.

15:18 idiosyncrat_ The new upload looks good -- I have a last minute scare -- a random segment violation -- one that I could not reproduce reliably.
15:19 idiosyncrat_ And was about to turn to this channel for assistance ...
15:20 idiosyncrat_ but I managed to track it down -- Lua's interface with C uses a stack which is not self-sizing -- the programmer is required to ensure there's enough stack space.
15:21 idiosyncrat_ And there was a place where I needed extra stack space but was not asking for it.
15:21 idiosyncrat_ So problem gone and all looks good.
15:25 idiosyncrat_ At http://irclog.perlgeek.de/marpa/2016-07-06#i_12791753 I said that I would pose a question to the IRC channel at this point in development, but I've had time to think and have answered it for myself.
15:27 idiosyncrat_ It was about what to do next -- add Lua actions, or new features to SLIF's BNF rules, such as counted rules and sequences within a RHS, such as
15:27 idiosyncrat_ A ::= B C* D
15:28 idiosyncrat_ On reflection, the logical order is to go ahead with the new SLIF BNF features.
15:28 idiosyncrat_ I'm still open to input, but that's what I'll do unless I get talked out of it. :-)
