ThakeeNathees / pocketlang
Pocketlang is a small (~3000 semicolons) and fast functional language written in C. It's syntactically similar to Ruby and it can be learned within 15 minutes. Including the compiler, bytecode VM and runtime, it's a standalone executable with zero external dependencies just as it's self descriptive name. The pocketlang VM can be embedded in another hosting program very easily.
You can try pocketlang on your browser. It's a WebAssembly build of the VM compiled using emscripten. Note that in the webassembly version of the language, some features (input, file handling, relative import, etc.) have disabled, has limited memory allocations, and the stdout calls might be slower.
The pocketlang documentation is hosted at https://thakeenathees.github.io/pocketlang/ which is built from the docs branch generated by a little python script at docs/generate.py. Note that the documentations are WIP and might not be up to date.
Pocketlang supports tail call optimization. When a function returns a call, the callee can re-use the caller's stack frame, this will optimize memory from O(n) to O(1) and for tail recursive it'll completely prevent stackoverflows and yet it's faster then tco disabled.
