Subject: <nocontext:> has no effect in rules with subpatterns
Date: Wed, 3 Jul 2019 07:16:23 +0300
To: bug-Regexp-Grammars [...] rt.cpan.org
From: Alexander Karelas <alex.karelas [...] gmail.com>
E.g.: my $parser = qr/     <name>     <token: name>         <nocontext:>         <word= (\w+)> /x; "alex" =~ $parser; use Data::Dumper; print Dumper(\%/); gives: $VAR1 = {           '' => 'alex',           'name' => {                       'word' => 'alex',                       '' => 'alex'                     }         }; ...which contains some context in name (where I think it should not)

Hi Alex, Thanks for the report, and apologies for the slow response. That's definitely a bug, and I'm working on a solution. The current workaround is to convert the named capture to a separate token, like so: my $parser = qr/ <name> <token: name> <nocontext:> <word> <token: word> \w+ /x; "alex" =~ $parser; use Data::Dumper; print Dumper(\%/); which gives: $VAR1 = { 'name' => { 'word' => 'alex' }, '' => 'alex' }; as expected. I will upload a new release as soon as I have found out what's going on with the named capture version, hopefully later this week. Once again, thanks for bringing this to my attention. Damian

I have found the bug, and fixed it. The problem no longer occurs in v1.052, which I have just uploaded to CPAN. Thanks again for the report, Alex. Much appreciated! Damian
