Autocompletions not working

[Rydgel]

Autocompletion does not seem to work properly, When typing, Enum. it does not propose any function from the Enum module. But instead only current file variables.

Did I miss something to configure?

Let me check; I'm not using the plugin my self, let me check if something broke.

So it seems to be working for me, do you have the elixir binary in a weird place?

You need to configure it in your project settings like it says here: https://github.com/edelvalle/SuperElixir#elixir-interpreter-settings

If you continue experiencing problems press: ctr-` and send me the logs.

Actually it seems to work after being triggered multiple times.

I noticed an error in the console so here it is:

Ok, now I know what's going on.

How this plugins works, Sublime plugin system is in Python and the library to do code introspection, autocompletion (ElixirSense) and all the heavy lifting is in Elixir. The plugin basically glues Sublime and ElixirSense... there is a piece of software here that is quite fucking complex here that is use to decode Erlang binary protocol and translate it back and forth to Python.

What you are experiencing is that the library to do the translation between Erlang binary protocol and Python is breaking because some unexpected result from Erlang to Python.

This is hard to debug, because I will need an example of the binary code that erlang is returning so I can check why it breaks this library.... I will tell you how to get it, but you need to give me some time. Ok?

[Rydgel]

Yup no problem, I'll help.

:+1: I think I might have a related issue - The completion (Both top-level and dot based) works for all standard modules, but it doesn't for any of my project or their dependencies.

I'm using Erlang 20.3 and Elixir 1.6.5.
