MeowScript🐾

The Purrfect Programming Language

Made by @Alen, inspired by 🐱

🐈 Cat-inspired Keywords: From purrhaps instead of if to meowtually instead of else, Meowscript adds a whole new level of catness to your programs.
😼 Paw-some Syntax: While being not easy to read, the syntax makes sure you have a Paw-some time writing code.
🙀 Fur-midable Performance: Meowscript may be cute, but it's no kitten when it comes to performance. The language is designed to be fast, well faster than Python atleast.

Let's paw-ceed with some purr-gramming!

Running with WebAssembly (Wasm) compiled from Rust ✨

Docs

MeowScript is a dynamically-typed and interpreted language inspired by cat-puns

Keywords

scratch: Used to declare a variable. For example, scratch x = 10; declares a variable x with the value 10.
amew: Used to reassign a new value to an existing variable. For example, amew x = 5; changes the value of the variable x to 5.

pawction: Used to define a function. For example,

scratch greet = pawction() { 
	meow("Meow!"); 
};

defines a function greet that prints "Meow!" to the console.

purrhaps: Used to start an if statement. Example:

purrhaps x > y { 
	meow(x is greater than y!"); 
}

meowtually: Used to start the else block of an if statement. Example:

purrhaps x > y { 
	meow("x is greater than y!"); 
} meowtually { 
	meow("x is not greater than y!"); 
}

tail: Used to return a value from a function. Example

scratch add = pawction(a, b) { 
	tail a + b; 
}

pawckage: Used to include external code from other packages. For example,

pawckage "file.meow";

NOTE: SEMICOLON IS NOT OPTIONAL

Types / Variables

All of the types are similar to other C-like languages, but we have specific names for certain types

whiskers - Strings

Eg: scratch say = "Meow!";

Note: They must be enclosed in double quotes

furrball - Arrays

Eg: scratch words = ["Meow", "Nya", "Nyo"];

Boolean:

purrfect: Represents the boolean value true.
clawful: Represents the boolean value false.

The furreal operator can be used to check the type of a variable. For example, furreal x; checks the type of variable x.

Loops

There's only a single type of loop in MeowScript

The keyword furrever can be used to start a loop that runs indefinitely. For example, furrever { scratch("Meow!"); } runs the block of code inside the loop forever.

Loop Control

The following keywords can be used for manupilating the contorl flow of the loop

hiss: Used to break out of a loop. For example, furrever { hiss; } will break the loop immediately.
continue: Used to skip the current iteration and continue to the next one in a loop. For example, pawction loop() { furrever { continue; } } will run the loop indefinitely but will skip each iteration.

Standard Libraries

Meowscript comes with a lot of Builtin Functions.

General

meow()

Prints the given values into the stdout

meow([...values])
