Enlightened Monks!
I wanted to play around with Regexp::Grammars, but it seems even the basic stuff eludes me. Could someone tell me what I'm doing wrong?
#!/usr/bin/perl
use v5.14;
my $sentence = "Show me the money";
my $grammar = qr{
<nocontext:>
<Sentence>
<rule: Sentence> <VerbGroup> <NounGroup>
<rule: VerbGroup> <Verb> | <Verb> me
<rule: Verb> <Word>
<rule: NounGroup> <Noun> | a <Noun> | the <Noun>
<rule: Noun> <Word>
<rule: Word> \w+
}x;
sub parse {
my $s = shift;
say "The sentence is: $s";
if ($s =~ $grammar) {
use Data::Dumper;
print Dumper %/;
}
else {
say "I did not understand you."
}
}
parse ($sentence);
I was expecting a data structure from which I could get $verb and $noun, but what I get instead is:
The sentence is: Show me the money
I did not understand you.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

are good places to start.
