Indigo

Indigo is an experimental multiparadigm programming language designed to lay focus on functional programming, clearity and convinience. Inspired by F# and Haskell, it aims to deliver satisfactory functional programming features, while exploring new concepts.

struct Person = (name: String, age: Int)

let greet (p: Person) => IO = println "Hello " : p.name
let main => IO = do
    let person = Person { name: "Lily", age: 22 }
    greet person
end
# Hello Lily

map (`*`2), [2, 4, 6, 8]     # [4, 8, 12, 16]

Features

Roadmap

• More advanced type system (e.g refinement types)
