Unusable for large projects

[jfrolich]

In a large elixir app there is a blocking lag before suggestions appear (3-5 seconds). It's already a bit noticeable in large elixir projects like Ecto, but there it's still sub-second. The app where this happens is ~ 20k lines of code with a number of large decencies like Ecto.

1. Elixir/OTP/Python version

Elixir: Elixir 1.6.4

OTP: 20

Python: 3.6.5

2. Are you using VIM or Neovim? Please provide the version.

Neovim/macvim

3. Which pluging are you using:

[ ] basic omnifunc
[ ] YouCompleteMe
[x] deoplete

4. Which steps of Debugging passed?

N/A

5. Do you have a specific setup? Like Docker and etc

No

@jfrolich are you experiencing something like this or slower?

I cloned the ecto project. the first autocomplete was slower because it had to run elixir_sense and wait for it to be responsive, the rest was quicker since the server is running.

Also please provide your neovim version

[jfrolich]

No much worse, see below. I have a 2015 macbook pro maxed out. And my neovim version is: NVIM v0.2.2

May I know if you are using latest version of alchemist.vim?

BTW the screencast that I posted is wrong :D

This is the correct one https://asciinema.org/a/7XtFQVLBLP37yw2XSvuaBd8OV
Still the first . after Ecto runs elixir_sense for the first time so there is some delay and after that that's the usually speed.

FYI when you are using Neovim and deoplete, the deoplete plugin looks up the spec faster because it has direct connection to elixir_sense socket(#120)

BTW how do you execute the autocomplete? Are you pressing or you have something else that triggers the autocomplete?

[jfrolich]

Yes using the latest version. I am pressing <C-y> to trigger the autocomplete.

@jfrolich do you have your vimrc file somewhere for me to try it locally?

I use vimbox (https://github.com/jordwalke/VimBox) so it's pretty huge 😅, with this adaptation:
