The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

November 2022 monthly "What are you working on?" thread
Since the last time I posted, I finished implementing pattern matching for schmu. To make matching on multiple columns less confusing I also added a tuple syntax to the language (finally), which are treated as anonymous records in codegen. Since then, I'm trying to overhaul my memory management, as my RAII-like solution only worked for linear code. In my first big departure from OCaml semantics, I decided to implement mutable value semantics. The paper linked in the Val language introduction makes a strong case for value semantics and after watching a couple of talks by Dave Abrahams, I wanted to try see how it feels. By making mutability be transitive and explicit, it also fixes one of the (few) gripes I have with OCaml that an array can never be really const as it is a reference type (it's possible to enforce constness with modules, but that's not exactly lightweight, syntax wise). Implementing mutable value semantics was pretty straight forward on the typing side, but I'm still not completely done with the codegen. This is due to 1. Assumptions about immutability I made in a lot of places are now wrong, and I had to completely change the way I pass values to functions. 2. I had to implement reference counted arrays, which was more work than I thought it would be. There are still edge-cases coming up in testing from time to time. Yesterday I finally managed it work for tail recursion, yay! I'm looking forward to getting rid of unneeded reference count updates in the future, by moving them to compile time, at least for linear code, lobster style. That's also an excuse to read that Perceus paper again. For the rest of November, I want to enhance my module system a bit. In particular, I want to add signatures and allow locally abstract types. I hope to have this in place before December to do the Advent of Code in my language.

September 2022 monthly "What are you working on?" thread
I'm still working on my toy language schmu, an ML-inspired language which uses LLVM as backend.

May 2022 monthly "What are you working on?" thread
I spent the time off over the Easter break to write the first program in my language which is not an explicit test and ended up implementing Ray Tracing In One Weekend. It was very rewarding to see how usable the language is already.

AG unification is the solution for type inference with scientific units
I've done a small implementation, used in type inference, in my language Boba. And you are correct, I used the linear equation solving method.

November 2022 monthly "What are you working on?" thread
The vast majority of October's improvements on Boba were type system and runtime bug fixes. In particular, the effect handler/delimited continuation semantics were hopelessly busted beyond a few simple examples I'd fixated on.

October 2022 monthly "What are you working on?" thread
September was another productive month for Boba, which is starting to get more 'quality of life' improvements rather than broad new features. That doesn't make the work less important: one of the bug fixes to the type inference engine last month caught a previously unseen bug in the core Boba libraries!

Unit Type System
Also worth checking out is Adam Gundry's work on type inference for UoM types. Or, if you want an example implementation of the Abelian unification used in standard type inference extended with UoM types, you can reference my implementation, based on solving linear equations.

August was a surprisingly productive month for the Boba compiler. A few highlights:

The next large feature for Boba (a general-purpose concatenative language) is language integrated property tests.

Soft-launch Boba: a statically-typed concatenative programming language
That's a good question! I wrote up some of my thoughts on the benefits of Go as a backend, but there's also a historical component here. The first backend I was experimenting with was compile-to-C plus a C-based runtime. Go was closer to C than C# for what I needed at the time and I thought had a nicer concurrency story as a backend.
