Grammar fails unexpectedly and then succeeds when Grammar::Tracer is imported in Rakudo #3611
Comments
From @masak<masak> star: grammar G { regex TOP { [<x> [';' | $$] \s*]* }; token x |
From @masak<TimToady> masak: no, it makes the grammar behave wrong, it turns out |
From @masak<masak> I need to digest those comments, though. I don't understand where the grammar "eats the newline that TOP needs to progress". Rejecting this ticket, as the problem seems to be entirely in Grammar::Tracer, not in Rakudo. See jnthn/grammar-debugger#13 for the ticket opened in Grammar::Tracer. |
@masak - Status changed from 'new' to 'rejected' |
From @masak<masak> TimToady_: ooc, do you agree that tracing a grammar breaks LTM matching? jnthn/grammar-debugger#13 (comment) |
Migrated from rt.perl.org#123452 (status was 'rejected')
