Hi,
I would like to turn a multiline string that looks like
1 A
2 B
into a hash that looks like
{
1 => "A",
2 => "B",
}
And I tought this was easy enough, however to my surprise this does not work:
use strict;
use Data::Dumper;
my $s = "1 A\n2 B\n";
my %h =map { $1 => $2 } $s =~ /(\d+)\s+(\S+)/mg;
print Dumper(\%h);
It produces
$VAR1 = {
'2' => 'B'
};
Could someone please explain to me what is going on here?
Many 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).
