This runs a build for a small elixir (phoenix) project in about 40 seconds by caching as much of the compiled files as possible.

We've been using this for months in multiple projects without any issues. Please ping be if there is any issues with this script and I'll update it.

It should be generic enough to work on any elixir app using mix.

If you have a elixir_buildpack.config, then enable that section in the build script to keep versions in sync!

2016-08-09: Updated to newer Erlang and Elixir and fixed curl command.

In many production systems you'll want to have one module capable of talking to many potential implementations of a collaborator module (e.g a in memory cache, a redis-based cache etc). While testing it's useful to control which module the module under test is talking to.

Here are the approaches I can see. The two points that seem to divide the approaches are their tool-ability (dialyzer) and their ability to handle stateful implementations (which need a pid).

Passing modules

Modules are first class, so you can pass them in. Used in EEx, where passed module must implement a behaviour.


	A list of languages which compile to JS (Elm, Purescript, OCaml)
	(Inspired by this thread: https://groups.google.com/forum/#!topic/elm-discuss/Um7WIBTq9xU)
	They all support curry calling convention by default.

	Some interesting results:

	1. `min` is curried function, only OCaml(BuckleScript) managed to optimize this overhead.
	2. All optimize the self tail call
	3. Only BuckleScript and PureScript type-specialized comparison functoin (>=) and inlined
