# koolml

#### koolml is a meta-lang inspired programming language that compiles to **javascript**

## Features:

- Regular expression based lexer

- Top-down recursive descent parser

- AST-walking interpreter

- REPL

- Javascript codegen

- Static typing

## Known bugs 

- String concat doesn't create a string, but a derived type of string 

- ```js 

    const x = new String("Hello") + new String("World")

    if (x instanceof String) { .... } // This results to false (why? why JS! why!!!!)

    ```

- The above doesn't work when matching a result of string concat

## Koolml doesn't require any third-party libraries. 

> ### Built on top of Abrvalg.

> ### Built using python3

## What the language looks like:

```ml

  module App ->

    fun main() ->

      print("Hello, world")

      let greet: String = "Hello, " + "World"

      print(greet)

```

## Aim of this language

- Learning principles of functional programmming from an imperative and OOP standpoint

- Functional programming on the web (on my own terms, no weird syntax and obscure language behavior)

- Create an alternative to JavaScript for using on my School projects (Web and CFB - computing Fundamentals B)

## You can find more examples in ``tests`` directory.

> ## How to try it:

```sh    

    git clone https://github.com/akrylysov/abrvalg.git

    cd koolml

    python -m koolml # starts a REPL

    python -m koolml -r ./test/factorial.ml # compiles the file and runs it using nodejs

    python -m koolml -b ./test/factorial.ml # compiles the file to a javascript file (no running)
