### Usage

At this point the compiler is written in TypeScript (eventually it will be rewritten in this language and self-hosted).

So you'll need node.js installed (and clang).

Running `npm i --save-dev && npx tsc` will compile the compiler.

```sh

# it currently just reads the `input` file

$ cat input

fn add(a: i32, b: i32): i32 {

    return a + b;

}

fn identity(v: T): T {

    return v;

}

fn main(): i32 {

    return add(identity(40), identity(2));

}

# run the compiler on that file

$ node .

parse: 1.564ms

name res: 0.453ms

typeck: 0.746ms

llir/mir codegen: 0.756ms

clang: 4.332ms

compilation succeeded

# run it

$ ./a.out; echo $?

42

```

You can also get errors

```sh

$ cat input

fn main(): i32 {

    return "";

}

$ node .

    return "";

    ^^^^^^^^^  type error: string is not a subtype of i32 (reason: 'Return')

```
