Building SSH Key management tool with Elixir

Sipping the Elixir

After being inspired by David's talk on Elixir at Hardhat, we decided to try and build our own SSH public key management tool PubKeys in Elixir. We're delighted to report back that Elixir is amazing and we've released the source code to the community at Github.

Things we love about Elixir:

Writing code in a functional style encourages us to break the code into small chunks of functions.
Through the use of function composition operator |>, this makes the code much more readable, and elegant.
Pattern matching is great.

	Making directory audio
	Compile audio/audio.c -> audio/audio.o
	Compile audio/source.c -> audio/source.o
	Compile audio/staticbuffer.c -> audio/staticbuffer.o
	Compile audio/staticsource.c -> audio/staticsource.o
	Compile audio/streamsource.c -> audio/streamsource.o
	Compile audio/vorbis_decoder.c -> audio/vorbis_decoder.o
	Making directory filesystem
	Compile filesystem/filesystem.c -> filesystem/filesystem.o
	Making directory graphics

	abstract class Building {
	constructor(public stories: number, public size: number) {
	}

	public height(): number {
	return this.stories * this.size;
	}
	}

	class Hardhat extends Building {

	namespace Structure {
	export type TabState = "impact" \| "timeline" \| "geography";
	export type OpState = "and" \| "or";

	export interface AppState {
	tab?: TabState,
	op: OpState,
	tags: Array<string>,
	}
	}

	namespace Structure {
	export interface Tab {
	preload(callback: () => void): void;
	execute(): void;
	build(set: Array<Structure.Person>): boolean;
	built(): boolean;
	}
	}

	class Impact implements Structure.Tab {

	interface Lengthwise {
	length: number;
	}

	function logger<T extends Lengthwise>(arg: T): void {
	console.log(arg.length);
	}

	logger([1,2,3]);
	logger({length: 20});

	function chunks(lst, size, step=1) {
	function generate(from, to) {
	if (from.length < step) {
	return to.concat(from)
	}

	return generate(from.slice(step, from.length),
	to.concat([from.slice(0, size)]))
	}
