# TurboScript
[](https://travis-ci.org/01alchemist/TurboScript) []() [](https://waffle.io/01alchemist/TurboScript) [](https://greenkeeper.io/)
Super charged typed JavaScript dialect for parallel programming which compiles to WebAssembly
# :warning: Major re-architecting is undergoing.
New spec (WIP) : [TurboScript Spec](https://github.com/TurboScriptLang/spec/blob/master/spec.md)
## Things going to change
* ### Binaryen as WebAssembly Backend
* ### Interop with TypeScript/JavaScript (Import well typed TypeScript to TurboScript, will not compile to WASM)
* ### Import any compiled WASM module to TurboScript
* ### Integration with WebPack
[](https://waffle.io/01alchemist/TurboScript/metrics/throughput)

TurboScript is an experimental programming language for parallel programming for web which compiles to JavaScript ~~(asm.js)~~ and WebAssembly (targeting post-MVP). The syntax is similar to TypeScript ~~(Hardly trying to fill the gaps)~~ and the compiler is open source and written in TypeScript. TurboScript has zero dependencies.
This is still an experiment and isn't intended for real use yet but we are working towards an MVP release. Please feel free to open issues if it stop working or need a new feature.
## [Try online](https://maxgraey.github.io/Assembleash/#TurboScript)
## Install
`npm install -g turboscript`
## Types
Type | Native type | Description
----------|-------------|-------------
`int8` | i32 | An 8-bit signed integer.
`uint8` | i32 | An 8-bit unsigned integer.
`int16` | i32 | A 16-bit signed integer.
`uint16` | i32 | A 16-bit unsigned integer.
`int32` | i32 | A 32-bit signed integer.
`uint32` | i32 | A 32-bit unsigned integer.
`int64` | i64 | A 64-bit signed integer.
`uint64` | i64 | A 64-bit unsigned integer.
`boolean` | i32 | A 1-bit unsigned integer.
`float32` | f32 | A 32-bit floating point number.
`float64` | f64 | A 64-bit floating point number.
`void` | none | No return type.
`string` | * | A utf-8 encoded textual data type.
`Array` | * | A generic array data type.
## Syntax
### variables
```typescript
var myGlobal:int32 = 1;
let evaluatedVar:int32 = myGlobal + 1;
// let is same as var.
```
### Number Literals
```typescript
let integer:int32 = 1234;
let integer64bit:int64 = 1234;
let floatingPoint:float32 = 1.234f;
let floatingPoint64bit:float64 = 1.234; // default floating point number is 64 bit
// You can also omit type since compiler infer type from the literal
let integer = 1234; // default integer is 32 bit, use type :int64 for 64 bit integer
let floatingPoint = 1.234f;
let floatingPoint64bit = 1.234;
```
### function
```typescript
// add.tbs
export function add(a:int32, b:int32):int32 {
return a + b;
}
```
### class
```typescript
// vector3D.tbs
export class Vector3D {
x:float32;
y:float32;
z:float32;
constructor(x:float32, y:float32, z:float32){
this.x = x;
this.y = y;
this.z = z;
}
}
```
### Generic
```typescript
class Foo {
value:T;
constructor(value:T){
this.value = value;
}
getValue():T {
return this.value;
}
}
export function testI32(value:int32):int32 {
let instance = new Foo(value);
return instance.getValue();
}
export function testI64(value:int32):int32 {
let value2 = value as int64;
let instance = new Foo(value2);
return instance.getValue() as int32;
}
export function testF32(value:float32):float32 {
let instance = new Foo(value);
return instance.getValue();
}
export function testF64(value:float64):float64 {
let instance = new Foo(value);
return instance.getValue();
}
```
### Operator overload
```typescript
class Vector3D {
x:float32;
y:float32;
z:float32;
constructor(x:float32, y:float32, z:float32){
this.x = x;
this.y = y;
this.z = z;
}
operator + (other:Vector3D):Vector3D {
return new Vector3D(this.x + other.x, this.y + other.y, this.z + other.z);
}
operator - (other:Vector3D):Vector3D {
return new Vector3D(this.x - other.x, this.y - other.y, this.z - other.z);
}
}
export function test():boolean {
let a = new Vector3D(1.0f,1.0f,1.0f);
let b = new Vector3D(1.0f,1.0f,1.0f);
let c = a + b;
return c.x == 2.0f && c.y == 2.0f && c.z == 2.0f;
}
```
### Array
```typescript
// f64-array.tbs
var a: Array = null;
export function test(num:int32): Array {
a = new Array(num);
let i:int32 = 0;
while (i < num) {
a[i] = 0.0;
i = i + 1;
}
return a;
}
export function getArrayByteLength(value:Array):int32 {
return value.bytesLength;
}
export function getArrayElementSize(value:Array):int32 {
return value.elementSize;
}
export function getArray(): Array {
return a;
}
export function getData(index:int32):float64 {
return a[index];
}
export function setData(index:int32, value:float64):void {
a[index] = value;
}
```
#### Compile to wasm
`tc add.tbs --wasm --out add.wasm`
