Mewlix is a cat-themed esoteric programming language that compiles to vanilla JavaScript. It's designed for making little HTML5 games!

Mewlix's compiler is written in pure Haskell, and is a self-contained binary executable. It can build projects, run them in a simple HTTP server, and package the build output neatly into a .zip file for upload in websites like itch.io.

As is tradition for all languages, here's a simple 'hello world' program in Mewlix:

meow "Hello world!"

And here's how to draw a sprite to the canvas in graphic mode:

from std.graphic takes load, draw, init

🐱 draw_cat()
  do draw <- "cat", 0, 0
~meow

do load <- "cat", "path/to/cat.png"
do init <- draw_cat

It has...

• Cat-themed syntax!
• A stack-like, LIFO persistent data structure—affectionately nicknamed a 'shelf'.
• String interpolation—:3"like [this]!"—affectionately nicknamed 'yarn strings'.
• Lambda functions, defined like this: 🐈 (a, b) -> a + b
• Classes, affectionately nicknamed 'clowders'.
• A function composition operator (:>) and a function application operator (|>)!
• nand and nor operators, for picky boolean expressions.
• Feline-oriented programming capabilities.

A big special thanks to my friend Jade for helping me stay sane through this project and for letting me talk endlessly about it these past few months. I wouldn't have been able to finish it without you, thank you! ♡
