Hi Monks,
Today when I was studying Perl 5.10 regex, I came across following problem.
When I matched the capture pattern in named variable, I printed it after substitution, but it was not printing.
when I print the same immediately after the expression, it works. Where am I going wrong?
So can't we use the %+ anywhere in program, just like normal hash?
use feature 'say';
$test = 'abc1234asf';
$test =~ /(?<one>\w{4})(?<two>\w{4})/;
#say 'one:', $+{one}; #works
#say 'two:', $+{two};
$test =~ s/(?<three>\w{4})(?<four>\w{4})/$+{four}$+{three}/;
say 'one:', $+{one}; #NOT works
say 'two:', $+{two};
say;
say 'three:', $+{three};
say 'four:', $+{four};
say;
say 'output:', $test;
OUTPUT:
-------
one:
two:
three:abc1
four:234a
output:234aabc1sf

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).
