Hey guys
Consider the following string: "a,b,c,d,5"
The format of the string is like this: "substr,substr,substr,...,value"
I use regex to check the string:
my ($value) = ($row =~ /.*,(.*)/); # gets value after the last comma
if (looks_like_number($value))
{
($row =~ s/,[^,]*$//); # gets substring before the last comma
# DO STUFF ...
}
# DO STUFF ...
It works fine but it doesn't look very good.
I cant understand why in
my ($value) = ($row =~ /.*,(.*)/); I need the brackets on the scalar but in
($row =~ s/,[^,]*$//); I don't need.
In other words, why is there is a syntax difference between the following two lines:
my ($value) = ($row =~ /.*,(.*)/);
my ($val) = ($row =~ s/,[^,]*$//);
Testing:
my $row = "a,b,c,d,15";
Output of first line:
15
Output of second line:
1 (why not a,b,c,d?)
How to do it in the same way?

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).
