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.

Reading configuration INI files in Perl

The INI file format is a simple file format that allows 2-level configuration options. It was extensively used in MS DOS and MS Windows, and it can be used in lots of places as it is very simple.

examples/config.ini

[openweathermap]
api = asdahkaky131

[aws]
api_key = myaws7980
api_code = qkhdkadyday

[digital_ocean]
api = seaworld

This format consists of section names (in square brackets) and in each section key-value pairs separated by and = sign and padded by spaces.
