2021.11 Two Year Itch

This week saw the return of not one, but two long time contributors with an extended blog post after a 2 year hiatus: one of them technical, the other more philosophical. It’s great to see these types of blog posts happen again! Yours truly is happy that it didn’t turn out to be a Seven Year Itch!

Towards a new general dispatch mechanism

Jonathan Worthington returns with a large technical blog post about the problem of implementing all of the various dispatch capabilities of the Raku Programming Language in a more efficient way. The article goes into what dispatch actually means, and why it matters to make it as fast and flexible as possible, and its relation to the RakuAST work. The good news in this, is that most of the discussed features are actually already implemented. In short:

The work that remains is enumerable, and the day we ship a Rakudo and MoarVM release using the new dispatcher feels a small number of months away.

No pressure! (/r/rakulang comments)

Why bother with scripting?

Bart Wiegmans returns with a large, more philosophical blog post about the contrast between scripting and programming, between scripts and applications. And how this affects the preferred features of a programming language. About Raku:

a language can be introduced for scripts and some of those scripts are then extended into applications (or even systems), thereby ensuring its continued usage

Thought provoking! (/r/rakulang comments)

Get Started with Terminal-UI

Brian Duggan has published a nice introduction into their Terminal::UI module, which shows the remarkable simplicity with which one can create fully interactive terminal applications with the Raku Programming Language (/r/rakulang, /r/commandline comments).

A match for *

Wenzel P.P. Peppmeyer elaborates on a question asked on the #raku IRC channel (by new Raku user PimDaniel) on how to turn a Match object into a lazy list: Raku is a match for * (/r/rakulang comments).

A Raku DevRoom at esLibre

JJ Merelo has been able to secure a Raku Devroom at the esLibre online event on 25/26 June 2021, one could argue to be the Spanish version of FOSDEM. The theme of the devroom is “A language for the 21st century“. Even though the most used natural language is Spanish, presentations in English will also be considered. So please, warm up your presentation ideas and submit them to JJ Merelo!

Raku Magic

Julia, a pretty recent Raku Programming Language aficionado, launched the idea of tweeting small pieces of Raku code for fun, relaxation and potentially profit! Just add your snippet, wait a little while, and it should then appear on Twitter! Yours truly could not resist!

Module documentation

About two weeks ago, Richard Hainsworth started a discussion about the documentation of Raku ecosystem modules, which was rekindled by Luis F. Uceta on /r/rakulang. Please leave any thoughts that you may have on the subject, either on the mailing list or on the /r/rakulang subreddit.

Raku documentation

Meanwhile, Alexander Kiryuhin has been working on a new version of the Raku Programming Language documentation web site (temporary URL). Although a lot of work has been done already, Alexander is specifically inviting your participation in the areas of JavaScript, to create a more immersive experience when looking at the documentation. Please check out the current issues that need solving before this could go live (/r/rakulang comments).

What’s everyone working on?

Daniel Sockwell stole an idea from other programming language communities: a free-form update on what people have worked on in the past week, with a focus on the Raku Programming Language of course. The first issue can be found on /r/rakulang, hopefully there will be many more to come!

Which scripting language should I continue to learn?

ItchyPlant asked that very question with regards to Raku vs Javascript vs PHP vs Python on /r/programming. With quite a few nice comments and suggestions, also in /r/rakulang.

7 Years of Raku performance improvements

Daniel Sockwell had their attention drawn to the benchmarks that H. Merijn Brand has been running for the past 7 years now (a subset of Text::CSV functionality).

RSC Meeting Minutes

Now that the Raku Steering Council has settled on more organized, bi-weekly meetings, it seemed like a good idea to actually write minutes of these meetings and publish them. These are the minutes of the RSC meeting on 6 March 2021.


Weekly Challenge #104 is available for your perusal.

Core Developments

  • Vadim Belman fixed a configuration issue on AIX.
  • Elizabeth Mattijsen fixed a recent regression in handling of nodemap / deepmap / duckmap if the block to execute contained a next statement.
  • And quite a lot of work on the RakuAST branch by Jonathan Worthington and Elizabeth Mattijsen.
