Suppose I want to do the following:
use MyModule 'foo' => 'bar', qw/do_something do_something_else/;
So I want to:
- Set the global configuration value foo to 'bar'
- import the class methods do_something and do_something_else into my namespace
Assume for this example that I don't need to be able to specify the value for foo at runtime.
I can define MyModule like so:
package MyModule;
our @EXPORT_OK = qw/do_something do_something_else/;
my $FOO;
sub import {
my ($class, %config) = @_;
$FOO = $config{'foo'};
}
sub do_something {
if ($FOO eq 'foo') {
# do something here
}
else {
# do something else
}
}
sub do_something_else {
if ($FOO eq 'foo') {
# do something else here
}
else {
# do something other than else
}
}
1;
But how would I then pass ('do_something', 'do_something_else') to Exporter?

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).
