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.

Continuous Integration (CI) means you create a very tight loop to get feedback for changes made to the code.

A good CI system will run every time you make some changes to the source code (or precisely every time you push it out to the hosted copy of your source code.)

In the CPAN Digger our goal is to understand and to help to improve the code that is CPAN.

Passing multiple parameters to a function in Perl

How can you implement a function that will accept several variables? After all in Perl all the parameters passed to a function are shoved into the @_ array of the function.

For example, what if you are creating a function to send emails. You would like the user to pass in a parameter for the "from" field, one for the "to" field, one for the "subject", one for the "plain text" version of the email, one for the "html" version of the email. Maybe even a parameter for the "cc" and the "bcc" fields.
