01:46 idiosyncrat_ harrysimons: re lib/Marpa/R3/MetaAST.pm
01:46 idiosyncrat_ Oops, I mean re https://irclog.perlgeek.de/marpa/2016-10-13#i_13390309
01:46 idiosyncrat_ "Unnecessary unit rule in priority rule" means that
01:46 idiosyncrat_ 1.) You are using a prioritized rule
01:46 idiosyncrat_ 2.) One of the alternatives is a unit rule
01:46 idiosyncrat_ A unit rule is a rule that amounts to "EXP ::= EXP"
01:46 idiosyncrat_ In most context these create harmful cycles.

01:48 Topic for #marpa is now Start here: http://savage.net.au/Marpa.html - Pastebin: http://scsys.co.uk:8002/marpa - Jeffrey's Marpa site: http://jeffreykegler.github.io/Marpa-web-site/ - IRC log: http://irclog.perlgeek.de/marpa/today
01:49 idiosyncrat_ You can look at your prioritized rules and check for an alternatives that is a unit rules -- that will be your problem.
01:50 idiosyncrat_ I hope this helps.
01:50 idiosyncrat_ harrysimons: and I hope you're backlogging!
01:52 idiosyncrat_ The ilbot3 disappeared on me for a few seconds and some of what I typed does not appear on the log -- I'll try to reenter:
01:52 idiosyncrat_ === Start of missing entries ===
01:52 idiosyncrat_ Priority rules give the LHS and RHS special treatment so the that LHS appearing on a RHS is actually a different symbol, chosen to create the priority schem
01:52 idiosyncrat_ So "EXP ::= EXP" is in a sense OK in a prioritized rule, but it is useless at best and very likely indicates some sort of confusion about what needs to be done.
01:53 idiosyncrat_ It's therefore reported as "unnecessary".
01:53 idiosyncrat_ === End of missed entries ===
01:54 idiosyncrat_ I guess the bot doesn't like it when I drone on with a lot of technical details. :-)
01:54 idiosyncrat_ harrysimons: Again, I hope this helps!
