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.

Pro: min, max, sum in Perl using List::Util

The List::Util module provides a number of simple and some more complex functions that can be used on lists, anything that returns a list anything that can be seen as a list.

For example these can be used on arrays as they "return their content" in list context.

Enable Appveyor (CI on Windows) for the Perl 5 Markua Parser

Travis-CI runs the test on a Linux box and I think it could also run on OSX, but I never tried that. Appveyor on the other hand is a cloud-based Continuous Integration that runs your tests on MS Windows. (Actually I just saw an e-mail from them inviting me to try their Linux servers as well. For now let's stick to the Windows machines.)

The Markua parser should have no platform dependent part. So our could is expected to run on MS Windows as well. I only have an old Windows 7 at home and I'd avoid using it. Luckily Appveyor can provide the platform to test the code.
