gnu-apl-mode

I had a little excursion into Dyalog APL recently and wound up writing an emacs mode to evaluate Dyalog APL [1]. It was a pretty nice experience using Claude to extract the small subset of features I wanted from gnu-apl-mode [2] to work with Dyalog APL. I’d really like to properly get into APL though. My plan is to solve a bunch of problems on Kattis [3]. I'm really enjoying this way of learning a new language in the age of LLMs - starting with easy problems on an online code judge website and work with an LLM to come up with/explain simple solutions. It gives me dopamine hits, lots of reps, allows me to start coding right away, and is a nice way to slowly ramp up difficulty and get practice with different features of the language.

I implemented Emacs support to handle exactly this. It also provides several other useful features such as formatting and code navigation. It's available on MELPA as gnu-apl-mode, or you can get it here: https://github.com/lokedhs/gnu-apl-mode As poor as this video is (and the last time I posted it I believe I said I was going to make a new one), it does illustrate some of the features: https://www.youtube.com/watch?v=yP4A5CKITnM

If anyone is interested in playing with APL, there is a free implementation in GNU APL[1] that works pretty well. I'm doing a bit of shameless advertising here, since I'm the author of gnu-apl-mode[2] which adds support for GNU APL to Emacs. If anyone have questions about this, I'll be happy to answer them here.

You can also use the Emacs mode (disclaimer: I'm the autor), which not only gives you reasonable input methods for APL characters, but also a lot of other features such a source code navigation and the ability to edit matrices in SES (the Emacs spreadsheet). https://github.com/lokedhs/gnu-apl-mode And a video I made to demonstrate some of its features: https://www.youtube.com/watch?v=yP4A5CKITnM
