Darklang-Classic has been running in production since 2019, first in a private beta for a few users/orgs, and eventually a public beta since then. Back when it was first deployed, the company supporting the product was in a fast-expansion ok-to-spend-VC-money phase, with vendors giving discounts to the org. Those

Like an aging rock star making a final stab at glory, I'm delighted to announce that Darklang is going all in on AI/GPT. As everyone knows, the folks over at OpenAI produced a magic box that writes code. And it even produces quite good code – not perfect,

We'd love you to sponsor Darklang's development! Long term, we'd like Darklang to be sustainable from the community. In the future, we expect paid accounts will support our development and maintenance. Until then, you can help build Darklang by sponsoring us via GitHub Sponsors.

tl;dr Release notes [7] [8] and release discussion Darklang Release 7 contains all the changes from October 2022, and Release 8 contains all the changes from November 2022. Writing these changelogs takes a bit of time, so we’re a month late, sorry! We’ve recently written a REPL

Rescript-tea is a Rescript implementation of The Elm Architecture, an MVU (Model-View-Update) pattern for organizing frontend applications and components. Darklang was one of the largest users of bucklescript-tea, the precursor to rescript-tea, and our entire client is built around it. Rescript has changed a lot since bucklescript-tea was written, and

Darklang release 6 contains all the changes from September 2022. Finally, we have support for negative numbers! To try them out, well, just like type the minus sign I guess.

For years, we've talked about building Dark in Dark. In fact, one of the most common questions we've had about Dark is why isn't it built in Dark? When you are talking about building a language in itself, typically it means a compiler being

Darklang Release 4 contains the changes from July 2022. Most of the changes this month were behind the scenes, aiming at releasing new type system, language, and editor features over the next few months. Nevertheless, we have a couple of nice features for you in this release including: * Dozens of

I'm pleased to announce Darklang Release 2. Release 2 is the first of a new versioning scheme we announced recently. We're doing a "Release" every month, which is just a set of release notes discussing what we shipped over the last month. Release 2

For the first few years of the life of Darklang, each time we didn't have a library available for our OCaml-based backend, or decided to build a feature in our DB instead of on a proper cloud server, we said "ugh, let's hack this and

I remember when I started at Mozilla, and I first got fully sold on continuous delivery. Mozilla had just released Firefox 4, a long and grueling change where some important CSS features had been ready but unshipped for over 18 months before Firefox 4 actually got out the door, slowing

We just slipped into March, so this is as good a time as any to review what happened in Darklang in 2021. While the bulk of this post is technical details about the rewrite, I have included some company details at the bottom too. Enjoy! For context, Darklang is an

It's 2022, and we're restarting Darklang community meetups!

and should it be open source? I'm taking a break from reporting on the progress of Darklang [https://darklang.com] (it's slow but steady [https://github.com/darklang/dark/pulls?q=is%3Apr+is%3Aclosed]) to write up some thoughts on an interesting question.

I recently went through an optimization exercise. As part of Darklang's rewrite in F#, I needed to make sure that my new code was as fast as the old code - or at least, not horrendously slow. A quick load test revealed the worst: the new code was
