The Onyx Programming Language

Onyx is a general purpose, efficient, procedural and pragmatic programming language for application development. Onyx compiles solely to WebAssembly through a custom backend, leading to blazingly-fast build times.

<!-- Once Onyx is able to be added to the GitHub syntax repo, this can be changed -->

use core {*}

Person :: struct { age: i32; name: str }

main :: () {
    // Generate a list of 30 random people
    people := Iterator.from(0 .. 30)
        |> Iterator.map(_ => Person.{
            random.between(1, 10)
            random.string(10, alpha_numeric=true)
        })
        |> Iterator.collect()

    // Sort them by age
    Slice.sort(people, (a, b) => a.age - b.age)

    // Group them by age
    group_iter := Iterator.from(people)
        |> Iterator.group_by((a, b) => a.age == b.age)

    // Print the groups of people
    for group in group_iter {
        printf("People of age {}:\n", group.first.age)

        for v in group.second {
            printf("    {}\n", v.name)
        }
    }
}
