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.

A copy-and-patch JIT compiler for CPython
Wow! Thank you for your hard work. I use python for all experimental work so this would speed up my scripting work, such as processing data from API calls or filesystem.
I wrote a simple toy JIT for a Javascript-like language. It might be useful for others to learn from because it's so simply written and not complicated. I do lazy patching of callsites, I haven't got anywhere near as advanced as tracing or copy-and-patching. Much of the code I wrote for this JIT was written in Python and ported to C. The Java Virtual Machine has a template interpreter which is interesting to research.
I haven't got around to encoding amd64 x86_64 instructions as bitmasks yet, so I've hardcoded it.

The path to implementing a programming language
Thank you for this article.
I'm a beginner to programming language implementation and design but here's what I learned. But what I want to do this with this comment I want to encourage you to start work on your programming language and just "Do Something©", Anything! You might have always dreamed to create a programming language. You can indeed try that! Have faith that you can do something, even if it's simple or incomplete, at least you learned something and got another skill.
I don't want to be trapped by the idea that building your own programming language is impossibly difficult and that it will never be used so what's the point.
It's so worthwhile.
You can still do something! Effort doesn't have to be wasted! Go and try write a simple virtual machine: it's just a for loop over instructions that manipulate memory. I wrote a non-bytecode compiler, which just uses List for instructions and HashMap for instruction arguments.
Andrew Kling built a browser and operating system and Terry Davis built an operating system. They encourage that someone can in fact learn a lot and do a lot.
I don't want to endlessy design things OR only write implementations. I think you can write lots of ideas down AND spend time implementing things and getting your keyboard busy.
I wrote this incomplete JIT compiler in C which has a simple nondesigned frontend that resembles Javascript. ANF is my intermediate representation.

I wrote a multithreaded imaginary assembly language that sends integers between threads through mailboxes but nowhere near LMAX Disruptor performance.
I think you should avoid spending too much time on your parser or lexer, use the Kaledeiscope LLVM tutorial to learn how to write recursive descent parsers and move onto code generation. I did mine with switch statements. The more you actually write parsers the easier it gets, but at first when you have no clue, you CAN just read someone else's implementation of it. Understand it, then write your own to your own design. if you get Analysis paralysis and worry about making a mistake or unoptimal decision and that prevents you from doing something suboptimal but actually do something.
I rushed through my compiler to get to the code generation step because my goal was code generation.
My dream: parallel and concurrent language that combines threads and coroutines with efficient interthread communication similar to LMAX Disruptor and allows writing of efficient pipelines that are serialisable like Temporal.io.

Mir: A lightweight JIT compiler project (2020)
Thanks for this.
I started a basic toy JIT compiler for a language that looks similar to JavaScript. It is incomplete.
https://github.com/samsquire/compiler
With these kinds of projects there is a lot of work to be done and I feel it's difficult to get started reading a codebase for a JIT compiler or gcc or LLVM.

Let's make a Teeny Tiny compiler
On thing you can do it implement a JIT compiler.
Here's Martin Jacob's code to execute arbitrary memory:
https://gist.github.com/martinjacobd/3ee56f3c7b7ce621034ec3e...
Since your C program is already in memory, you have access to the C standard library and don't have to worry about linking or object formats :-) but you'll have to worry about parameter passing and FFI.
My JIT compiler based on this idea is here https://github.com/samsquire/compiler but it is incomplete.

Erlang: More Optimizations in the Compiler and JIT
This is interesting, thank you.
I really should learn from BEAM and the OTP and learn Erlang. I get the feeling it's super robust and reliable and low maintenance. I wrote a userspace multithreaded scheduler which distributes N lightweight threads to M kernel threads.
https://github.com/samsquire/preemptible-thread
I recently wrote a JIT compiler and got lazy compilation of machine code working and I'm nowhere near beginning optimisation
https://github.com/samsquire/compiler
How do you write robust software, that doesn't crash when something unexpected goes on?
I looked at sozo https://github.com/sozu-proxy/sozu
and I'm thinking how to create something that just stays up and running regardless.
- Is it possible to optimize this bytecode interpreter more?
- How do you create a correct AST with interaction between method call and function call?

Gren 0.3: Source maps
Great! I have not yet made source maps for my programming language that compiles to WebAssembly, and I probably never will.

What is the most absurd error message your compiler/interpreter was once outputting?
Up until today, my AEC-to-WebAssembly was, if somebody tried to use two structures of different types as the second and the third operand to the ?: (ternary conditional) operator, as in this example: ``` Structure First Consists Of Nothing; EndStructure

Good languages for writing compilers in?
Well, I have written the first compiler for my programming language, targetting x86, in IE6-compatible JavaScript, and the second compiler, targetting WebAssembly, has been written in C++11. I think that, to choose a language to write a compiler in, you need to look at at least two things:
-
Why does GCC run in Docker produce around 30% smaller statically linked C++ executables than GCC run on Linux? AECforWebAssembly is 1.08 MB large if compiled using GCC 13.1 in Docker, but it is 1.59 MB if compiled using GCC 13.1 on Debian.
You can see the releases v2.5.3 and v2.5.2 of AECforWebAssembly on GitHub. They are produced with the same version of GCC, the only difference (as far as I know) is that v2.5.2 was produced directly on Debian, whereas v2.5.3 was cross-compiled from Windows to Linux using Docker.

Let's Make Sure Github Doesn't Become the only Option
That could be true. I host my AEC-to-WebAssembly compiler on GitHub, GitLab and SourceForge, and it's only on GitHub that it has 21 stars and 2 forks. On GitLab and SourceForge, it has zero of both.

Does the JVM / CLR even make sense nowadays?
Well, the main compiler for my programming language is targetting the JavaScript Virtual Machine by outputting WebAssembly. I think it's even better than targetting Java Virtual Machine, because, for one thing, your executables can run in any modern browser if you output WebAssembly. If you target Java Virtual Machine, the users need to actually download your app. Furthermore, there is an official assembler for WebAssembly called WebAssembly Binary Toolkit (WABT), so your compiler can output assembly and not have to deal with binary files. There is nothing equivalent to that for Java Virtual Machine.
