Distel-completion

Distel-completion is an Erlang completion library for both

  • auto-complete-mode
  • company-mode using Distel as a backend.

Usage:

with auto-complete-mode

(require 'auto-complete-distel)
(add-to-list 'ac-sources 'auto-complete-distel)

with company-mode

(require 'company-distel)
(add-to-list 'company-backends 'company-distel)

There is also optional parameters which can be modified.

(setq company-distel-popup-help t)

This will render company's doc-buffer (default <F1> when on a completion-candidate) in a small popup (using popup.el) instead of showing the whole help-buffer.

(setq company-distel-popup-height 30)

This variable specifies the height of the help popup created by company.

Extras

Get Erlang-docs from internet

Get the documentation from the internet:

(setq distel-completion-get-doc-from-internet t)

Change completion symbols

Change the allowed symbols to skip backwords in order to find start-of-word. (showing defaults)

(setq distel-completion-valid-syntax "a-zA-Z:_-")

Current issues

  1. fail: badrpc
fail: [rex [badrpc [EXIT [undef ([distel describe (io format 3) nil]
[rpc -handle_call_call/6-fun-0- 5 ([file rpc.erl] [line 206])])]]]]

This error comes when trying to get the documentation for a completion candidate. It actually uses same functionality as erl-fdoc-describe (C-c C-d d), and if this function stops at "Sent request; waiting for results..", it is the same fault.

  1. In company-mode restart completion after completing a module.

  2. Show whether the completion candidate is of a module or a local function.

  3. Add some formatting to documentation-buffer.
