Dear Monks,
I have a .pl file which was done by perl trainers.
I need to write the code to validate the .pl file which was done by perl trainers.
The following are I have to write code to validate them.
1. Find the unncessary grouping.
i.e.
$a=~s#(foo)(bar)#$1#;
Here first group only given in replace, but second group not in replace. So It'll eat memory unnecessarily.
2. If variable declared, but not in use anywhere. It'll show.
3. If there is a subroutine, but it'll not call anywhere, It'll show.
...
...
I need to validate these things in my coding. Please give if there is any short way or any modules.
Thanks in Advance.
Kanishk

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
