In my previous post I talked about how Racket Mode now will often want the back end command server, before actually needing a live REPL — but it has to start a REPL anyway. This was bothering me. So I went on to address that. Doing so entailed reversing the I/O model for the back end. As a bonus, that set up fairly short strokes to supporting multiple REPLs.

During most of January and into February, I’ve been working full-time to have Racket Mode make better use of drracket/check-syntax analysis of fully-expanded code. I’m pretty excited by it.

For most of the last decade I’ve made things in Racket — including making tools and tutorials to support other people making things in Racket.

At RacketCon 2019, Aaron Turon gave the keynote about the Rust community.

That afternoon, I had a talk about Racket Mode for Emacs.

The next morning?

For the first time, ever, I’ve been using Linux on raw hardware for a couple months. The experience has been utterly boring and wonderful.

In racket-mode I improved support for the multi-in form provided by racket/require.

I’m writing and publishing this post using something other than Frog.

Having said that, I’m not planning to abandon maintaining Frog.

Sometimes people want Racket threads to have useful names — for example to show in logger output. Here is one way to do it.

Even though it’s been one of my most time-consuming projects, I’ve hardly blogged about racket-mode — an Emacs major mode for Racket. To change that, here’s a post giving an overview of how racket-mode works, as well as a look at how it might grow someday.

In my previous post I discussed what I’m doing with deals.extramaze.com — and what I’m intentionally not doing. Since then, I’m not-doing more. This improves performance and simplifies the content security policy.

For Extramaze LLC I’m using Racket in a commercial project — a search engine with email alerts for deals on music gear — deals.extramaze.com.

This blog post is a sort of whirlwind tour of the use case and business model, as well as how I use things like Racket, PostgreSQL, and AWS — but don’t use advertising or JavaScript.
