company-elixir

company-mode completion backend for Elixir.

It uses a separate IEx (Elixir's interactive shell) process to fetch completions from.

WARNING: This is an experimental package. It can be used as an example of an async backend for the Company completion framework - see my post. It works but I don't use anymore.

Installation

Add company-elixir to your load path:

(add-to-list 'load-path "path/to/company-elixir.el")

Add elixir-mode hook:

(add-hook 'elixir-mode-hook 'company-elixir-hook)

Notes

• Since company-elixir uses IEx to fetch completions from, your Elixir project should be in a correct state so it can be compiled to run IEx.
• company-elixir finds completions for modules only by full path. For example, Foo.Bar. will work, alias Foo.Bar; Bar. won't work. See More features section.
• Keep in mind that EIx starts your application. So if your processes do some heavy work, you may want to disable them. company-elixir supports customization of iex command with company-elixir-iex-command variable. For example, you can modify it with your custom environment variables.

More features

• Support of completion of aliased modules will come soon.

Potential features

Since we already obtained IEx process, we can use it to:

• Fetch docs with b/1
• Interpret Elixir expressions from Emacs
