Include Modules Automatically?

meetraz has asked for the wisdom of the Perl Monks concerning the following question:

I have my own library of modules which function sort of like plug-ins:

use MyPlugins::ModuleA;
use MyPlugins::ModuleB;
use MyPlugins::ModuleC;
(etc)
[download]

This list is now a couple pages long, and tedious to maintain. Is there an easier way to just automatically include all the modules installed in a certain directory (e.g. MyPlugins) without specifying them manually somewhere?

Or do I have to resort to a File::Find hack?

The File::Find hack (and some more) live in Module::Pluggable	[reply]

The following module will import every module in directory Foo and export everything the submodules export, and is a potential security risk for pathological file names: `package Foo; use strict; BEGIN { my @modules = (); opendir DIRHANDLE, 'Foo'; while (my $file = readdir DIRHANDLE) { if ($file =~ /\.pm$/) { $file=~s/\.pm//; push @modules, $file; } } closedir DIRHANDLE; require Exporter; our @ISA = qw(Exporter); our @EXPORT = (); for my $module (@modules) { eval 'use Foo::'.$module; { no strict 'refs'; push @EXPORT, @{"Foo\:\:$module\:\:EXPORT"}; } }; } 1;` [download] Update: Forgot to close the directory handle.

Try Toolkit. It lets you keep a list of modules to use in a file.	[reply]

When they are all similarly named like this, I tend to go for the Module::Find approach: `package MyPlugins; use Module::Find (); Module::Find::useall( __PACKAGE__ );` [download] Although you need a bit more than that if the modules are exporting things. www.jasonkohles.com We're not surrounded, we're in a target-rich environment!
