Inko is a language for building concurrent software with confidence. Inko makes it easy to build concurrent software, without having to worry about unpredictable performance, unexpected runtime errors, or race conditions.

Inko features deterministic automatic memory management, move semantics, static typing, type-safe concurrency, efficient error handling, and more. Inko source code is compiled to machine code using LLVM.

Hello world:

import std.stdio (Stdout)

class async Main {
  fn async main {
    Stdout.new.print('Hello, world!')
  }
}

A simple concurrent program:

import std.sync (Future, Promise)

class async Calculator {
  fn async fact(size: Int, output: uni Promise[Int]) {
    let result = 1.to(size).iter.reduce(1, fn (product, val) { product * val })

    output.set(result)
  }
}

class async Main {
  fn async main {
    let calc = Calculator()

    match Future.new {
      case (future, promise) -> {
        # This calculates the factorial of 15 in the background, then we wait
        # for the result to be sent back to us.
        calc.fact(15, promise)
        future.get # => 1307674368000
      }
    }
  }
}
