Problem Statement

Create a directory and any missing parents. This task is named after the posix mkdir -p command, and several libraries which implement the same behavior. Please implement a function of a single path string (for example ./path/to/dir) which has the above side-effect. If the directory already exists, return successfully. Ideally implementations will work equally well cross-platform (on windows, linux, and OS X). It's likely that your language implements such a function as part of its standard library. If so, please also show how such a function would be implemented.

Let's start with the solution:

import "io" for FileSystem

class Main {
    construct new() {}

    init() {
        FileSystem.createDirectory("path/to/dir")
    }

    update() {}

    draw(alpha) {}
}

var Game = Main.new()

import "io" for Directory

Directory.create("path/to/dir")
