rct-complete error in vim8

[jonahx]

I've successfully installed deoplete and deoplete-rct on macvim 8.0, and I'm getting the following error as I type inside a ruby file:

The relevant part of my .vimrc looks like:

Plugin 'roxma/vim-hug-neovim-rpc'
Plugin 'roxma/nvim-yarp'
Plugin 'Shougo/deoplete.nvim'
Plugin 'Shougo/deoplete-rct'
let g:deoplete#enable_at_startup = 1
let g:deoplete#enable_yarp = 1

I've verified that the command rct-complete works on my cmd line. Am I missing any steps?

I cannot reproduce the problem.

set rtp+=~/.cache/dein/repos/github.com/Shougo/deoplete.nvim/
set rtp+=~/.cache/dein/repos/github.com/Shougo/deoplete-rct/
set rtp+=~/.cache/dein/repos/github.com/roxma/nvim-yarp/
set rtp+=~/.cache/dein/repos/github.com/roxma/vim-hug-neovim-rpc/

let g:deoplete#enable_at_startup = 1

filetype plugin indent on

Please test the above vimrc and the reproduce ways from Vim starting. If you don't upload them, I will close it. Because it works for me.

[Shougo]

And please upload :messages result.

[jonahx]

Thanks for the fast reply.

I want to clarify, I did not install using dein, and ~/.cache/dein does not exist on my system. Should I still attempt the above test?

[Shougo]

Please change the path to the vim-plug installed plugin path.

[jonahx]

I just tested with the following ".vimrc" (my installs were done using vundle):

set pythonthreedll=/usr/local/Cellar/python3/3.6.3/Frameworks/Python.framework/Versions/3.6/Python
set rubydll=/usr/local/Cellar/ruby/2.4.2_1/lib/libruby.2.4.dylib
set luadll=/usr/local/Cellar/lua/5.3.4_2/lib/liblua.dylib

set rtp+=~/.vim/bundle/vim-hug-neovim-rpc/
set rtp+=~/.vim/bundle/nvim-yarp/
set rtp+=~/.vim/bundle/deoplete.nvim/
set rtp+=~/.vim/bundle/deoplete-rct/
let g:deoplete#enable_at_startup = 1
let g:deoplete#enable_yarp = 1

1. The error I originally posted about in this issue still occurs.
2. Perhaps related, and I should have mentioned before, but even if I comment out "deoplete-rct" line, deoplete's suggestions are slow -- they take about 5 seconds to appear, even on small files. I'm on a 16G RAM MB Pro.

Any ideas?

Thanks again.

Please upload the reproduce ways frorm Vim8 starting. I cannot reproduce the problem.

Really? I cannot reproduce it.

Please upload the reproduce ways.

Please reproduce it for me.

We cannot fix the not reproduce-able problem. We have not the magic power.

Re: the original problem, here is the relevant output from :messages:

Regarding the slow behavior, what should I do to reproduce it for you, besides the miminal .vimrc I posted? I can take a video, or capture any other info you need. I'm just not sure what that is.

Thanks, Jonah

We have not the magic power.

Your plugins suggest otherwise :)

[Shougo]

It seems rcodetools error. It is not both deoplete and deoplete-rct error. I cannot fix it.

Please upload the Ruby code.

Re: the rct problem, you are right -- I will investigate that myself within the context of rct.

Re: the slowness, it happens with all files, not just ruby. So the simplest thing is to show you it happening in the minimal ".vimrc" itself that I posted earlier:

NOTE: That video is in real time, and not slowed down.

If you need any additional debugging info, let me know. Also, since this is about deoplete itself at this point and not deoplete-rct, let me know if I should repost it as a deoplete issue and we can close this.

Thanks.

[Shougo]

@jonahx It is very slow. It is not deoplete-rct problem. Please create the another issue in deoplete. And please enable profile and upload the log file. I will check it.

       let g:deoplete#enable_profile = 1
       call deoplete#enable_logging('DEBUG', 'deoplete.log')

[Shougo]

And the log file:

       $ export NVIM_PYTHON_LOG_FILE=/tmp/log
       $ export NVIM_PYTHON_LOG_LEVEL=DEBUG
       $ neovim
       ... Use deoplete
       $ cat /tmp/log_{PID}
