Crabby: The Modern Programming Language Written in Rust

Introduction

NOTE⚠️: Crabby is still under development with new features and bugs being fixed, if you encounter an error then that's OUR fault (boohoo) and we're still fixing it. Crabby is very new due to the rewrite update and is still is experiencing bugs and errors. You can help fixing Crabby if you want to.

Crabby is a Modern High-level, Versatile, Multi-paradigm, general-purpose, and a hybrid approach programming language. It is designed to be readable, ease-to-use for beginners, and powerful enough for advanced users.

Crabby is leaning into multi-paradigm, supporting paradigms like OOP and Procedural style of programming. But if you want the functional nature of Crabby, It is still a Functional programming language by default.

It syntactically resembles Python, But it's a Functional programming language by default.

What Change?

As you may notice, Crabby has been through phases of rewrite, and if you're thinking that Crabby is abounded, well... You're Wrong!

Crabby has been officially and well be written in Rust due to it's memory safety and type checking compared to C.

Here's what changed:

1. It has Pythonic-style of Syntax BUT with a functional approach
2. It's purely functional (not yet for now)
3. JIT compile time
4. Runtime & Type checking on the work.
5. Error handling on the work
6. More parsing and features!

Installation

Note: We highly recommend to use the nightly toolchain edition of rust

Step 1: Make sure to have git and rust/cargo installed

git --version
cargo --version

Step 2: Git clone

git clone https://github.com/Kazooki123/crabby.git

Step 3: Build it and Test it for yourself

cargo build
cargo run examples/example.crab

Syntax

In Crabby🦀, its' syntax mostly resembles Python in general BUT there are hints of Functional Programming syntax since Crabby aims to be versatile, functional and powerful to use not just for advanced programmers but for beginners also!

It's default file format is a .crab or .cb But for now it's .crab

example.crab:

let x = 42
let y = 314
var z = 10 // You can use the 'var' keyword too!
let message = "Hello, Crabby!"

print(x)
print(y)
print(z)
print(message)

functions.crab:

pub def foo() {
    print("Hello!")
}

foo()

helloworld.crab:

print("Hello, World!")

math.crab:

// addition
let x1 = 1
let y1 = 2

// multiplication
let x2 = 4
let y2 = 7

// subtraction
let x3 = 10
let y3 = 3

// division
let x4 = 10
let y4 = 3

print(x1 + y1)
print(x2 * y2)
print(x3 - y3)
print(x4 / y4)

ifelse.crab:

// if-else statements

let x = true
let y = false

if x {
    print("True!")
} else {
    print("Nope!")
}

loops.crab:

let x = range(10)

for i in x {
    print(i) // Prints it 10 times
}

let y = 10

for i in range(y) {
    print(i)
}

Note: Crabby supports commenting, use // to comment out a code or leave a silly ahh message :3

Speaking of comments, Crabby also support Docstrings!

Package Manager📦

The closest package manager Crabby can have is crab🦀 (which is still in development), it functions likely the same as Rust cargo but for Crabby
