Code-Maven series

If you are a beginner, or would like to refresh your Perl programming knowledge, you can go over the Perl tutorial or watch the Beginner Perl Maven video course.

If you need to maintain a large piece of software written in Perl by other people in the last 5-10-15 years, that's a challenge. Especially if you did not get proper training in Perl. You are probably limited to a specific and old version of Perl. Check out, the Perl tutorial! You can probably skip the part about installing Perl, but the rest of the tutorial will be relevant for you.

Perl is often used in Test Automation. If you work in this field, or if you'd like to work in this field (it is much more fun to find bugs in other people's code than in yours :), then you can read the Perl tutorial and the series on Test Automation using Perl.

If you build new web applications - either privately or inside a company - you can start by reading the article comparing CGI, mod_perl and PSGI. From there you can go on reading the generic Perl tutorial or the articles on Mojolicious, Perl Dancer, Catalyst, PSGI/Plack, or even CGI, the Common Gateway Interface, for old-school web applications.

In the off chance you are interested in topics other than Perl, especially related to Test Automation, Continuous Integration, Continuous Deployment, DevOps, then you are welcome to check out the list of DevOps related training courses.

Pro: Fix the documentation of the MtaCPAN::Client

Earlier we tried to write some code to fetch the list of most recently uploaded Perl modules.

We found that the documentation of MetaCPAN::Client::Release isn't accurate.

The name attribute returns the name including the version number and the distribution returns the name only.

Start using the MetaCPAN API Client to fetch the list of most recently uploaded Perl modules

MetaCPAN is the place where you go if you'd like to find a Perl module and if you'd like to read its documentation.

It also has a public API so we can write a script to search for various things for us.

For example we would like to be able to fetch the most recently uploaded modules.

Moo with hash reference as attributes - with or without default values

TL;DR use: default => sub { {} }

Moo can also have attributes where the value is a HASH reference and you might want to ensure that even if the user has not supplied an HASH reference at the construction time, the attribute still has an empty hash. So you write this code:
