# NativeTS

A modern Typescript transpiler to llvm

## Installation

```

npm i -g native-ts

```

## Help

to get help on how to compile your typescript code, just run the following command:

```

native-ts --help

```

## How does it work

This program converts typescript code into native binary code or into llvm code.

### Example

typescript code:

```ts

class Hello {

    constructor() {}

    sayHi() {

        console.log("Hi!");

    }

}

var hello = new Hello();

hello.sayHi();

```

llvm IR:

```llvm

; ModuleID = 'main'

source_filename = "main"

%Hello = type {}

%string = type { i8*, i32 }

@0 = private unnamed_addr constant [4 x i8] c"Hi!\00", align 1

declare i32 @main()

define i32 @main.1() {

entry:

  %0 = call %Hello* @Hello__constructor()

  %hello = alloca %Hello*

  store %Hello* %0, %Hello** %hello

  %hello.load = load %Hello*, %Hello** %hello

  call void @Hello__sayHi(%Hello* %hello.load)

  ret i32 0

}

define %Hello* @Hello__constructor() {

entry:

  %0 = call i8* @gc__allocate(i32 0)

  %1 = bitcast i8* %0 to %Hello*

  ret %Hello* %1

}

declare i8* @gc__allocate(i32)

define void @Hello__sayHi(%Hello* %this) {

entry:

  call void @console__log(%string { i8* getelementptr inbounds ([4 x i8], [4 x i8]* @0, i32 0, i32 0), i32 3 })

  ret void

}

declare void @console__log(%string)

```
