When matching terminals, Parse::RecDescent seems to produce a match if a token begins with the terminal, rather than trying for an exact match. This code demonstrates this:
#!/usr/bin/perl
use warnings;
use strict;
use Parse::RecDescent;
my $grammar = q{
FOO: "foo"
};
my $p = Parse::RecDescent->new($grammar);
my @tests = ("foo", "foo ", "foo bar", "football", "fog", "barfoo", "b
+ar foo");
for my $test (@tests) {
if (my $ret = $p->FOO($test)) {
print "match: '$test' -> '$ret'\n";
}
else {
print "no match: '$test'\n";
}
}
This isn't what I want. I want it to produce an error/return undef when what was entered doesn't match in full, rather than simply eating the remainder.
I doubt this is a bug, because it seems too trivial, so I suspect that this is actually a lack of understanding of parsing in general on my part. Could someone please set me straight here? Thanks!

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).
