Day 15 – Santa had too much eggnog

Santa had too much eggnog We’re just over a week from Christmas and Santa is sending his elves the final present lists. Unfortunately, Santa had a bit too much eggnog and so the list that he sent to his elves was … not the greatest. Take a look at some of it: Santa somehow managedContinue reading “Day 15 – Santa had too much eggnog”

Day 14 – Thinking Beyond Types: an Introduction to Rakudo’s MOP

It’s Christmas season! Christmas would not be Christmas without the caroling that’s part of the festivities, so let’s make it possible to sing some. We could simply make a carol one giant string, but that’s not good enough. Being a song, carols often have a chorus that’s repeated in between verses. If we were toContinue reading “Day 14 – Thinking Beyond Types: an Introduction to Rakudo’s MOP”

Day 13 – A Little R&R

A Little R&R Introduction Raku is a really nice language. Versatile, expressive, fast, dwimmy. The only problem I sometimes have with it is that it can be a little slow. Fortunately that can easily be solved by the NativeCall interface, which makes it easy to call C code in your Raku program. Now, as niceContinue reading “Day 13 – A Little R&R”

Day 12 – Making a simple bot in Raku

Making IRC bots is incredibly simple in Raku, thanks to IRC::Client. It allows you to create a very simple bot in about 20 lines of code. There’s a plugin system that allows easy re-use of code between multiple bots, and adding customized features can be as easy as dropping in an anonymous class. So, let’sContinue reading “Day 12 – Making a simple bot in Raku”

Day 10 – A Teaser

Day 9: a chain (or Russian doll) of containers

If you’re in the business, you’ve probably by now heard about containers. They can be described as executables on steroids, or also, as its namesake, a great way of shipping applications anywhere, or have then stored and ready to use whenever you need them. These kinda-executables are called images, and you can find them inContinue reading “Day 9: a chain (or Russian doll) of containers”

Day 8 – Parsing Firefox’ user.js with Raku (Part 2)

Yesterday, we made a short Grammar that could parse a single line of the user.js that Firefox uses. Today, we’ll be adding a number of test cases to make sure everything we want to match will match properly. Additionally, the Grammar can be expanded to match multiple lines, so we can let the Grammar parseContinue reading “Day 8 – Parsing Firefox’ user.js with Raku (Part 2)”

Day 7 – Parsing Firefox’ user.js with Raku

One of the simplest way to properly configure Firefox, and make the configurations syncable between devices without the need of 3rd party services, is through the user.js file in your Firefox profile. This is a simple JavaScript file that generally contains a list of user_pref function calls. Today, I’ll be showing you how to useContinue reading “Day 7 – Parsing Firefox’ user.js with Raku”

Day 6 – Put some (GitHub) Actions in your Raku (repositories)

After being in beta for quite some time, GitHub actions were finally introduced to the general public in November 2019. They have very soon become ubiquitous, over all combined with the other release that were recently made by GitHub, the package (and container) registry. We can put them to good use with our Raku modules.Continue reading “Day 6 – Put some (GitHub) Actions in your Raku (repositories)”
