Subject: Regular expression syntax errors after adding simple regexps when unroll_plus is enabled
Download (untitled) / with headers
text/plain 816b
Hi, 1 bugs is reported by a Debian user : This perl script terminates with error like: Unmatched ( in regex; marked by <-- HERE in m/\A( <-- HERE (x)\*(\??)\Z/ at /usr/share/perl5/Regexp/ line 2734. --->8--- use strict; use Regexp::Assemble; my $ra = Regexp::Assemble->new(unroll_plus => 1); # any of bellow valid regular expression can be uncommented, to show problem #$ra->add('((a|b)cz+)?'); #$ra->add('((ab|cy)z)'); $ra->add('((x)y)'); # simplest one #$ra->add('((x)+y)+'); #$ra->add('(b(x))'); #$ra->add('a(b(x))'); print $ra->re; ---8<--- It looks that Regexp::Assembler incorrectly handles paranthesis for some reasons in this simple expressions. Interesingly despite this "simplest one" example not having "+" operator, Regexp::Assemble behaves correctly after disabling unroll_plus option!
Perhaps will help in some way.
