ExExport
This library provides an easy way to make barrel files in Elixir.
A barrel is a way to rollup exports from several modules into a single convenient module.
The barrel itself is a module file that re-exports selected exports of other modules.

I have grown used to having a lot of little files that get bundled up into a library (blame my time working in node/ES6 land). Because of the compiled nature of Elixir it seemed like this style of file structure should work without run time penalties.
This directive is an experiment to enable that. It allows me to build API barrels the same way I do in Javascript.
/lib api.ex actions/
welcome.ex
farewell.ex
#api.ex
defmodule API do
require ExExport
alias API.Actions.Welcome
ExExport.export(Welcome)
ExExport.export(API.Actions.Farewell)
end
This adds defdelegate for all public methods in the referenced files.
Installation
If available in Hex, the package can be installed
by adding ex_export
to your list of dependencies in mix.exs
:
def deps do
[
{:ex_export, "~> 0.1.0"}
]
end
