This toy was somewhat broken#
About six years ago, I wrote about lazy, which is a tool that will auto-install Perl dependencies for you as they are required. It’s not unique – it has been done before. But this implementation uses a different installer (cpm) and it also allows you to pass in some flags directly to the installer. I think it’s fun, but it had some problems and it didn’t always work the way I wanted it to. I should have fixed it sooner, but I’m lazy.
Today I wanted to use it and I was so annoyed that I decided to have another look at it. But, it was after my work day and I was feeling lazy. So I asked GitHub Copilot to fix the biggest bug for me. It was deep recursion. Surprisingly, Copilot immediately grasped and fixed the issue. (At least it seems that way to me). Once that was done I took a closer look and decided to fix some design decisions that were making the internals overly complicated. I did that on my own. Then I added some GitHub Actions to give me a little more confidence in my changes and soon it was ready to ship.
Now it’s a better toy#
As of right now version 1.000000 of lazy is now available for you to
download. You can check it out on
MetaCPAN.
Have some fun with it#
At the command line#
# Auto-install missing modules globally
perl -Mlazy foo.pl
# Auto-install missing modules into ./local
perl -Mlazy='-Llocal' foo.pl
# Auto-install missing modules into ./some-other-dir
perl -Mlazy='-Lsome-other-dir' foo.pl
In your code#
# Auto-install missing modules globally
use lazy;
# Auto-install missing modules into ./local
use local::lib;
use lazy qw( -L local );
# Auto-install missing modules into ./some-other-dir
use local::lib qw( some-other-dir );
use lazy qw( -L some-other-dir );
# Auto-install missing modules into ./some-other-dir and pass
# more options to App::cpm
use local::lib qw( some-other-dir );
use lazy qw( -L some-other-dir --man-pages --verbose --no-color );
In a one-liner?#
Install App::perlimports via a one-liner, but why would you want to?
$ perl -Mlazy -MApp::perlimports -E 'say "🧅"'

And that’s really it. I hope you have fun using it. I hope it makes you more productive. But, most importantly, I hope it leaves you more time in the day to goof off and, you know, just be lazy.
