White-Oak / coki-jit

A simple language with JIT

Coki JIT

I've found peruse to be a great parser combinator library and coki — an amazing point to start using it.
My goal was to implement a working JIT for a simple language.

Current version is working on 64-bit Windows and 64-bit Linux.

Original README is providen below:

Coki

Coki is a simple language written in Rust. Right now Coki is interpreted, but fairly soon it will be compiled via LLVM.

This is mostly just a toy language for me to:

• write stuff in Rust!
• demonstrate my peruse parser-combinator library
• try writing a LLVM front-end

"Features"

• the only first-class type is signed integer
• all variables are global (scope coming soon!)
• the only reserved keywords right now are if, else, while, and out

Here's a program to output the first 30 Fibbonacci numbers.

n1 = 1
n2 = 1
n = n1 + n2
i = 0

while i < 30 {
  out n
  n2 = n1
  n1 = n
  n = n1 + n2
  i = i + 1
}

Here's an example of "fizzbuzz". Since Coki doesn't have strings yet, we'll use "1" as "fizz" and "0" as "buzz". Also there's no logical connectives yet (soon!!)

n = 1

while n <= 100 {
  if n % 3 == 0 {
    if n % 5 == 0 {
      out 10
    } else {
      out 1
    }
  } else if n % 5 == 0 {
    out 0
  }
  n = n + 1
}

The name comes from Coki Beach in St. Thomas, US VI, which is where I was when I decided this project needed a name.
