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.

April 2021 monthly "What are you working on?" thread
Apart from the language I also built a simple website for Aument, a JSON parser in Aument and incomplete bindings for libuv.

March 2021 monthly "What are you working on?" thread
Since last month, I've added a lot of changes to my programming language, now named Aument, namely classes, method dispatching and the module system.

I've been lurking here for a while, but never actually created a Reddit account. So, as a first post, hi! This month I'm working on aulang, it aims to be a portable and embeddable dynamic scripting language like Python or Lua. It is prepreprepreprepre alpha so don't expect it to be that amazing, but it has the bare minimum features and the language can even be compiled to native code through C (currently only works on Linux).

I just switched Pika to using significant indentation. This is mostly because of how annoying line continuation is in a ML-style language (so f a b syntax) without significant indentation or required semicolons, but you can read more about the reasons for that decision in this section of the README.

May 2021 monthly "What are you working on?" thread
Recently, I've been working on adding garbage collection to Pika. I've successfully written an Immix-based garbage collector that works with the LLVM GC support infrastructure, and I'm currently working on integrating the GC with Pika, or really Durin, the dependently-typed intermediate representation that Pika compiles to. Because types are passed around at runtime, objects of unknown type and size can be stored unboxed in polymorphic data structures; but that makes keeping track of type information for heap allocations somewhat harder, because type information needs to be allocated and constructed at runtime in some cases. It's an interesting design problem, because you want constructing type information to be fast; but the GC will run much more often, so maximizing tracing speed by avoiding e.g. indirection in type information is important; and you also want to construct as much type information as possible at compile time and embed it as constants.

I've been working on adding algebraic effects to Pika during the past month. It's turned out to be harder than I thought it would, but I'm almost done - performing and catching one effect at a time works, and the compilation strategy I'm using now (I reimplemented the whole thing after realizing the strategy I was using wouldn't actually work) should be enough to handle multiple effects at once and also effect polymorphism, I just have to get those working in the elaborator.

After taking a break from Pika, my dependently-typed ML for systems programming, during the month of January, I've started working on it again by getting recursion to work properly. I'm planning on starting to implement algebraic effects next, and an Immix-based garbage collector for boxed values after that. Here's what my current plan for algebraic effects looks like:
What are some alternatives?
kuroko - Dialect of Python with explicit variable declaration and block scoping, with a lightweight and easy-to-embed bytecode compiler and interpreter.
konna - A fast functional language based on two level type theory
star - An experimental programming language that's made to be powerful, productive, and predictable
durin - the Dependent Unboxed higher-oRder Intermediate Notation
xvm - Ecstasy and XVM
bluebird - A work-in-progess programming language modeled after Ada and C++
lisp - A lisp JIT compiler and interpreter built with cranelift.
rumi - The rumi compiler
pkg-tasks - Aument package for asynchronous I/O
starlight - JS engine in Rust
yasl - Bytecode Interpreter for Yet Another Scripting Language (YASL).
c3c - Compiler for the C3 language
