This blog post describes a model that we found useful for talking about CPAN dependencies and reverse dependencies at the QA Hackathon. At the head of the river is Perl itself with the core modules. The river flows into the sea, which contains all distributions that aren't used by any other distribution. Other distributions sit somewhere along the river, their position determined by their reverse dependencies. This post introduces the core concepts, but nothing more.

Where should I look for perl 6 libraries?

modules.perl6.org.

When I've chosen one, how can I add it to my perl 6 project?

Use zef to install it on your local system.

Read the modules doc page for directions on useing a module in your project.

If I find it [somewhere], how can I add it to my perl 6 project?

If zef can see it (and zef will usually be able to see a module if its repo is listed at modules.perl6.org) then zef should be able to install it. If not, contact the author or ask about it on #perl6.

As an answer to point 2) and 3) , you can take a look at 6pm. It's idea is to be NPM for Perl6. It works over Zef.

$ 6pm init

# Install dependencies to ./perl6_modules and add it to META6.json 
$ 6pm install Test::Meta --save

# Run a file using the local dependencies
$ 6pm exec-file test.p6

# Make your code always use 6pm by making it "use SixPM;"
$ perl6 test.p6
