Ludi

This is 'Ludi' an experimental programming language. Inspired by APL, it is focused on multidimensional arrays, and has a number of basic features that you can play around with in the interpreter. I am logging and documenting the developement at twilson.xyz

Example

> let x = [4 3 2];
> let y = 5;
> print(x*y)
    20 15 10
> let z = reshape(iota(8), [2 2 2])
> print(z)
    1 2
    3 4

    5 6
    7 8
> fn inc(x) { x+1 }
> print(inc(1));
    2
> print(inc([0 0 1]));

    1 1 2
> print(inc(z));

    2 3
    4 5

    6 7
    8 9

Usage

With a standard Rust toolchain it the interpreter can be built and run:

cargo run -p interpreter

Current Goals & Progress

• Interpreter (80%)
• Type checking (75%)
• Code generation (50%)
• Optimizations (10%)

Dependencies

• Rust 2021 edition
• LLVM 18 and MLIR via the melior crate
  • It is recommended that you clone & build melior in the same directory as you put this one
