Hummingbird

Hummingbird is a language inspired by JavaScript, ML, and Swift. It features/will feature a usable type system with ML-inspired type inference, JavaScript code generation, and a concise syntax designed for readability.

Example

An obligatory hello world:

let welcome: String = "Hello "
func sayHello () -> Boolean {
  console.log(welcome + "world")
  return true
}
sayHello()

For more examples see the specification and manual.

Specification

The Hummingbird specification is designed to be both human- and machine-readable. It is organized into sections for each syntactical and semantic feature of the language.

Each feature has a <spec name="..."></spec> block containing the Hummingbird example source and the expected JavaScript output. These can then be parsed and a full suite of unit tests generated in test/spec/.
