Disclaimer!

Please do not take this project too seriously. I'm in no way a professional. To be honest, I'm surprised myself that Snekky is even somewhat usable.

About

Snekky is a simple object-based, imperative programming language compiling to a custom bytecode. Checkout the specification for more information.

Features

  • Built-in REPL.
  • Familiar syntax.
  • Compiles to a custom bytecode.
  • Arrays and hashes.
  • Lambdas and closures are supported.
  • Almost everything is an expression (including ifs, whens and blocks).
  • Final (let) and mutable (mut) variables.
  • Destructuring of arrays and hashes.
  • for ... in loops with iterators.
  • As flexible and dynamic as a snek.

Installation

Compile it yourself

  1. Download and install Haxe.
  2. Clone this repository.
  3. Compile the project by executing haxe scripts/build-cpp.hxml.
  4. Binaries will be located in cpp/.

Download release binaries

Builds can be found in the releases tab or the actions tab (login required).

Usage

  1. Create a file called input.snek in a text editor (e.g. Visual Studio Code).
  2. (optional) Install the Snekky VSCode extension for syntax highlighting.
  3. Enter some code (check out the examples).
  4. Run it using snekky input.snek.

Run snekky --help for more information.

Example

For more examples, checkout the examples folder.

// An implementation of the classic FizzBuzz programming test
for let i in 0..100 {
    Sys.println(when {
        i % 3 == 0 && i % 5 == 0 => "FizzBuzz"
        i % 3 == 0 => "Fizz"
        i % 5 == 0 => "Buzz"
        else => i
    });
}

REPL

The REPL allows you to quickly test a few lines of code by entering them one after the other. Syntax highlighting and automatic block indentation are supported. REPL
