CColon (C:)

CColon is a bytecode-compiled programming language built in Go. It takes the readability of Python, the structure of Go, the expressiveness of Kotlin, and wraps it all into a language that is genuinely enjoyable to write.

CColon compiles source code to bytecode and executes it on a stack-based virtual machine. Go's garbage collector handles memory management, so you never have to think about it.

Features

• Clean syntax with Python-like readability
• Bytecode VM for fast execution
• Garbage collected through Go's runtime
• Dynamic lists and fixed-size arrays
• First-class functions with parameters and return values
• Interactive REPL for quick experimentation
• Cross-platform binaries for Linux, macOS, and Windows

What it looks like

import console

function factorial(int n) int {
    if (n <= 1) {
        return 1
    }
    return n * factorial(n - 1)
}

function main() {
    var string name = "CColon"
    console.println("Welcome to " + name + "!")

    for i in range(1, 8) {
        console.println(i.tostring() + "! = " + factorial(i).tostring())
    }

    var list scores = [95, 87, 92, 78]
    scores.append(100)
    console.println("Scores: " + scores.tostring())
}
