What is Akro?

Akro is a modern programming language that combines:

• 🐍 Python's simplicity — clean, readable syntax
• ⚡ Go's speed — fast execution, fast startup
• 🌐 JavaScript's web power — transpiles to JS, runs in browser

fn main {
    name := "World"
    say "Hello, {name}!"

    nums := [1, 2, 3, 4, 5]
    total := reduce(nums, fn(a, b) { return a + b }, 0)
    say "Sum = {total}"
}

Install

Windows:

# Run as Administrator
.\install.ps1

From source (requires Go 1.21+):

git clone https://github.com/ST/akro
cd akro/src
go build -o akro.exe .

---

Usage

akro run main.ak          # Run a file
akro repl                 # Interactive shell
akro transpile main.ak    # Convert to JavaScript
akro check main.ak        # Type check
akro fmt main.ak          # Format code
akro version              # Show version

Syntax

// Variables (type inferred)
x := 10
name := "Akro"

// Functions
fn add(a, b) {
    return a + b
}

// If / Elif / Else
if x > 5 {
    say "big"
} elif x == 5 {
    say "equal"
} else {
    say "small"
}

// Loops
for i in 0..10 {
    say "i = {i}"
}

// Structs
struct Point {
    x: int
    y: int
}

// Pattern matching
match x {
    case 1 => say "one"
    case 2 | 3 => say "two or three"
    default => say "other"
}

// Error handling
try {
    throw "oops"
} catch(e) {
    say "Caught: {e}"
}

// Async/Await
async fn fetchData(url) {
    data := await http_get(url)
    return data
}

---

Web Development

Akro transpiles to JavaScript — write Akro, run in browser:

// app.ak
fn main {
    btn := document.getElementById("btn")
    btn.onclick = fn {
        say "Hello from Akro!"
    }
}

akro transpile app.ak   # → app.js

<script src="app.js"></script>
