# degu-lang

A take at a scripting language with an ML (Meta Language) family syntax. Heavily inspired by F#, OCaml and at some extent - Rust.

### Setting up the project

You need to have a local LLVM sdk. [The llvm cmake guide](https://llvm.org/docs/CMake.html) will help you as well as [the llvm-sys crate](https://crates.io/crates/llvm-sys) since that is what the project depends on.

What I've found useful is to pass a parallel build flag to `cmake --build`. For Windows' MSVC this is `/maxcpucount:` and would look something like `cmake --build . --config MinSizeRel -- /maxcpucount:4`.

The current required version of LLVM is 6 which will change when I get to recompile LLVM again.

Other than just run `cargo run -p compiler`.

### Example output

main.dg

```f#

let max3 a b c = if a > b then a else if b > c then b else c

let ifs a b c value =

    value + max3 a b c

let number_ops a b c =

    print_number a

    print_number b

    print_number c

    ifs a b c ((a + 1) * (a + 1) + 2 + (4 + 5 * 2 - 10)) - 4

let main _ = print_number (number_ops 1 2 3)

```
