note w-ber <p> Done, and also received feedback already! Here's the bug report: [https://rt.cpan.org/Ticket/Display.html?id=39323] </p> <p> And here's the solution I was seeking, based on <code>demo/demo_errors.pl</code>: </p> <code> use strict; use Data::Dumper; use Parse::RecDescent; # Simple Lisp S-expressions (as an example) my $grammar = q# start: expression(s?) | { die join("\n", map { $_->[0] } @{ $thisparser->{errors} })."\n" } expression: /\w+/ | '(' expression(s?) ')' { $item[2] } | <error> #; my $p = Parse::RecDescent->new($grammar); # This will die if there is an error. print Dumper($p->start('(foo (bar))')); # Like so: $p->start('(foo'); </code> <div class="pmsig"> <div class="pmsig-399589"> <p> -- <br> say "Just Another [href://http://prometheus.frii.com/~gnat/yapc/2000-stages/slide36.html|Perl Hacker]"; </p> </div> </div> 710640 711504
