( #3333=superdoc: print w/replies, xml ) Need Help??

Hi all

I am trying to write a simple grammar just to learn how to use Parse::RecDescent. Why this doesn't work "as expected"?:

my $p2 = Parse::RecDescent->new(q( hyphen : "-" option : "a" | "b" | "c" Format : Entry(s) Pre : hyphen option Post : option hyphen Entry : Pre | Post { use Data::Dumper; print Dumper \%ite +m;} )); $p2->Format('a-'); $p2->Format('-a');

I would expect both strings matching and printing "-a" or "a-", but I get:

$VAR1 = { 'Post' => '-', '__RULE__' => 'Entry' };

i.e. Both are valid patterns, but only the first one triggers the action

I would expect getting this:

$VAR1 = { 'Post' => 'a-', '__RULE__' => 'Entry' }; $VAR1 = { 'Post' => '-a', '__RULE__' => 'Entry' };

I am not getting something obvious here... Any help would be appreciated

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:

      Should cpanminus be part of the standard Perl release?
