Steve’s Corner

You may have heard me mention App::Crag before – it’s a command line application implemented as a Raku module. CRAG is an acronym for Calculator using RAku Grammar.

I have been working on it as a hobby for some time. I feel that now it is mature enough to bring it to the attention of a wider community (in this case, the r/CLI subreddit). Please give it a test drive and feel free to comment and feedback over there – maybe it will help to showcase the kind of cool stuff we have been keeping to ourselves.

And, since CragCLI is a presentation layer on several awesome Raku modules – kudos to those authors and contributors… here are a few I would like to highlight (there are many more unsung heroes)…

• Anton Antonov, Brian Duggan, Elizabeth Mattijsen and Holli Holzer.

Timo’s Corner

Timo Paulssen explains all you want to know about…

What are the ways our JIT compiler can tell other parts of the system (including not just the OS, but also development tools such as profilers and debuggers) information about the code it spits out?

Required reading for Raku core developers and geeks in general.

Nadim’s Corner

Nadim Khemir presents v1.5 of the excellent Data::Dump::Tree module.

DDT is a highly recommended boost to the standard Data::Dumper dd capability. I look forward to test driving v1.5 soon.

Winding down

Sorry for the self-serving promotion this week. What I am hoping is that by posting out some “packaged” Raku goodness like CragCLI, we can develop a little more interest in Raku within other developer communities. Not sure if this is going to bear fruit, but since I have been scratching this personal itch for some time, it seems like it is worth posting out there in the “wild”.

Please keep staying safe and healthy, and keep up the good work! Even after week 58 of hopefully only 209.
