UndefinedLanguage

UndefinedLanguage is experimental programming language that targets WASM. We do our own code-generation from scratch instead of relying on LLVM or similar code-generation technologies.

This is project done during free time.

Compile and Run

Write the code in demo.ul and do:

# Zig 0.14.1
zig build run -- demo.ul

resulting out.wasm will be written, localhost the root, open index.html and check Javascript Console.

TODO

• A better analyzer/type-checker
• Different int/float type of different signedness and size
• Arrays
• Tuples?
• JS FFI and bind WebGPU
• Proper Erroring (get as many as error possible before quitting + better error messages)

Analyzer

• No Variable shadowing
• No implicit conversion
• No type-change of variable after declared
• Type inference

WASM

• Remove hardcoding of some of wasm code-gen
• var x: float = 5; interpret 5 as integer, so generated wasm code assignmet doesn't work.

FUTURE TODO

• Suggest related variable names, for example, programmer types x_ids but only x_idx exist, so it will suggest x_idx.

Immediate Plan

• Be able to draw triangle on webpage with webgpu.

Future Plan

1. Be able to parse all the basics feature a programming language can have. (functions, arrays, loops, etc)
2. Design custom IR
3. Use this IR to codegen WASM code
4. Do optimization on custom IR to produce efficient builds.
