Hello fellow monks,
I have a quick question concerning the aliasing of functions. Consider the following example:
#!/usr/bin/perl -w
use strict;
local *basename = \&pathname;
print basename('/usr/local/bin/ssh'), "\n";
sub pathname {
my ($dir) = shift;
my ($path, $name) = ($dir =~ /(.*)\/([^\/]*)$/);
# if called as basename, return filename, otherwise return pathname
+(how?)
return $path;
}
How can I get the name of the called function, so I can vary the output based on which function was called? I want the function to return the pathname if called with 'pathname', and the filename if called with 'basename'.
I have been reading about function templates and closures, which seems handy in case one has many aliases; but I wonder if there is a more easy way to just get the called function name, considering I only have one alias.
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).
