Devel::Loaded(3)

💖 NAME 💖

Okay bestie, welcome to Devel::Loaded(3) — this page is from the User Contributed Perl Documentation, and the whole mood is: Post-execution dump of loaded modules. Slay.

🌸 SYNOPSIS 🌸

perl -MDevel::Loaded programname 2>/dev/null

✨ DESCRIPTION ✨

Okay so Devel::Loaded installs an at-exit handler that generates a dump of all the module files used by a Perl program. It's literally giving main-character energy: “show me everything you loaded” 🔥.

If you use it together with a perl -c, you find those files loaded in at compile time with use. Compile-time only, bestie. If you are willing to wait until after the program runs, you can get them all. No cap.

🦋 EXAMPLES 🦋

This is compile-time only:

$ perl -MDevel::Loaded perldoc 2>/dev/null
/usr/local/devperl/lib/5.00554/Exporter.pm
/usr/local/devperl/lib/5.00554/strict.pm
/usr/local/devperl/lib/5.00554/vars.pm
/usr/local/devperl/lib/5.00554/i686-linux/Config.pm
/usr/local/devperl/lib/5.00554/Getopt/Std.pm

This will also catch run-time loads:

#!/usr/bin/perl
use Devel::Loaded;
...
