# trout-script

Compiled, strongly-typed scripting language written in javascript.

*This was my first (real) attempt at writing a full programming language.

I learned a lot in the process, and will eventually return to make it stable and

clean everything up.*

## Features

- strictly typed variables

- runtime within Javascript

- compiler emits 'runtime operations' as js

- struct types

- function closures

- explicit control of context within closures

- readable, unambiguous syntax

## Examples

  ```c

  var x = 1  // inferred type

  var y:int  // not initialized, but declared

  var hello:string

  hello = "world"

  

  struct Node {

    val:string

    next:Node   // struct allows recursive definition

  }

  struct vec {

    x:int = 0,  // default values

    y:int = 0

  }

  // functions declared with 'fn' and '(' arguments ')'

  fn factorial(x:int) int { // return type can be inferred by compiler

    var out = 1             // specified following arguments

    loop (x > 0) {

      out *= x--

    }

    return out

  }

  print('fact(10) = '|to_string(factorial(10))) // '|' concatentates strings

  var head:Node // structs are initialized when declared

  head.val = "I'm first"

  var next:Node

  next.val = "I'm next"

  head.next = next

  loop {

    if (head.next == null) {

      break

    } else {

      print(head.val)

      head = head.next

    }

  }

  ```
