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.

In a nutshell: After you register on their website you need to send 4 pull-requests to any GitHub hosted project in October. The first 50,000 people get a cool T-shirt.

Use the same sub as function or as method in Perl

When you write a modules, sometimes you'd like to allow your users two ways of operations. A simple one for which you provide a single function and a complex one where they need to instantiate an object of your class and call methods.

Sometimes you'd like to use the same function name for both case.

I found an examples in version 1.000031 of Text::Markdown

Let's see how does it work:
