Hey!

I've been messing with this, and hit a weird bug where if I called nvim.api.buf_set_lines, I got back the error pynvim.api.nvim.NvimError: b"object of type 'int' has no len()".

This was when calling it with 0, 0, -1, True.

Looking at the code for nvim_buf_get_lines and set lines, it looks like the first argument buffer is treated as the buffer, rather than the buffer index, as implied by the nvim docs :

Parameters: 
                    {buffer}           Buffer handle, or 0 for current buffer

Or over in

EXT Type	C type					Data
  ------------------------------------------------------------------------
  Buffer	enum value kObjectTypeBuffer		|bufnr()|

I could be entirely wrong, and my code is just working oddly, but if I add in a buffer_contents = vim.buffers[buffer] (or I guess vim.current.buffer for buffer == 0) and then use buffer_contents rather than buffer, the set and get work as expected.

Is that expected, or am I just using the function wrong?

Saw this warning when starting Vim after upgrading to python 3.7.0:

[vim-hug-neovim-rpc] Vim(pythonx):/must>not&exist/foo:1: DeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses
Press ENTER or type command to continue

how hard would that be to switch?

With commit 5a20db1, UNIX domain sockets was introduced, yet it only supports Linux and MacOS (Darwin). Additional systems can easily be added. There are a few options, but I am not sure which is best. Here is what I am currently using:

The test for posix is the most broad, but I do not know if it would include any systems that cannot handle it. While sys.platform would work, it would grow fairly quickly since the BSD's all have the version of the OS appended to them. There is finally platform.system() which is basically uname -s which would work too and be easier than sys.platform.

Another alternative is to try defining the class and handle the exception. It should work everywhere:

Can you add this rpc api support?

I use nvim.options['ignorecase'] to check vim option, it works in neovim, but fail to work in vim8.

The log says nvim_get_options was not implemented

2017-06-22 11:54:35,640 [INFO @ session.py:request:97] 19060 - 'Received error: [1, b'nvim_get_option not implemented']

I checked neovim_rpc_server_api_info.py, nvim_get_option was defined, but not implemented.
I add the implement in neovim_rpc_methods.py and it works as expected.

def nvim_get_option(name):
    return vim.options[name]

def nvim_set_option(name, val):
    vim.options[name] = val

I'm a little curious about the difference of nvim/vim python client.

import vim
print(vim.options['ignorecase'])

This snippet works on both neovim and vim with :py3file

But when I add import vim to my plugin, it reported No module named 'vim'

  File "C:\Users\jia.sui\AppData\Local\nvim\plugged\gen_tags.vim\pythonx\cm_sources\gtags.py", line 5, in <module>
    import vim
ImportError: No module named 'vim'

Does anyone know the difference?
Thanks

After installing vim-hug=neovim-rpc, I proceeded to the mentioned test for a valid installation:

Use :echo neovim_rpc#serveraddr() to test the installation. It should print something like 127.0.0.1:51359.

However, what I get is /tmp/vmrUX9X/2, quite different from what seems to be expected. I am not entirely sure how problematic that can be, but indeed ncm-R is not working with vim-hug-neovim-rpc.

Since a few days, I get the following error message when launching Vim on my (uptodate) Archlinux x86_64 :

[vim-hug-neovim-rpc] Vim(pythonx):ImportError: No module named neovim 
Error detected while processing function deoplete#enable[9]..deoplete#initialize[1]..deoplete#init#_initialize[10]..<SNR>120_ini

line   18:
E605: Exception not caught: [vim-hug-neovim-rpc] requires one of `:pythonx import [pynvim|neovim]` command to work

I think the problem occured after an update, either to my System (there has been a lot of python packages updated recently) or to my Vim Plugins after a PlugUpdate.

To solve the this problem, I tried different solutions found on the Web, but no luck.
Finally, I uninstalled several packages pip, neovim, greenlet, ... and reinstalled neovim.

$ sudo pip3 install neovim

but without success, error remains the same !

Vim says :

:echo has('python3')   --> 0
:echo has('pythonx')   --> 1

Please, can you help ?

Hello,

first of, apologies if this is not the right place to ask. I cannot for the life of me figure out how to get this plugin to work. I have vim version 8.1 with python3 support (has('pythonx') and has('python3') both return 1) and I have installed neovim via pip (both locally with the --user flag and globally with sudo to see if it changes anything), but when running :echo neovim_rpc#serveraddr(), this is what I get:

[vim-hug-neovim-rpc] failed executing: pythonx import neovim
[vim-hug-neovim-rpc] Vim(pythonx):Traceback (most recent call last):
Error detected while processing function neovim_rpc#serveraddr:
line   15:
E605: Exception not caught: [vim-hug-neovim-rpc] requires `:pythonx import neovim` command to work
Press ENTER or type command to continue

Have I perhaps missed an installation step?

Thanks in advance!

So, I am using deoplete and coc. And I want to use deoplete for some filetypes, and coc for others.
What I want to do is use coc.vim for javascript, coc has its vim-node-rpc client, which is conflicting with vim-hug-neovim-rpc. I need vim-hug for deoplete to work in vim.
Now, what I do now is remove vim-hug from rtp. But, I don't think it's the right way to do it.

autocmd FileType javascript set runtimepath-=~/.config/nvim/repos/github.com/roxma/vim-hug-neovim-rpc
autocmd FileType javascript set runtimepath-=~/.config/nvim/repos/github.com/roxma/nvim-yarp

Is there a way to turn it off?

Tests and CI are needed for the plugin to keep the compatibility.

This may help other plugins' vim8 support

eg, deoplete, Shougo/deoplete.nvim#339

"pip3 install neovim" successed,

Not really your problem, but maybe the right place to gather information on how to get this running on NixOS.

Installing python36Packages.neovim doesn't make this plugin visible in vim, so vim-hug-neovim-rpc will fail to import neovim python module. My config is

Hello,

TDLR: For all windows users, install vim64bit and python64bit before running python3 -m pip install pynvim in a normal windows cmd.

Long story:

After multiple hours of searching, span accross multiple trials last year, and this year, I finally found the solution of a perplexing issue. Maybe it’s worth mentioning in the readme ?

I had both python32 and python64 installed on my system, and was using gvim-32bit (as blindly adviced in https://github.com/vim/vim-win32-installer/releases ).

Running :py3 import pip; pip.main(['install', '--user', 'pynvim']) from vim would trigger some errors because pip.main is not available anymore after pip 10. after correcting this, then some errors where pip complains that it’s not a tty.

However, running python3 -m pip install pynvim from the windows cmd works fine !

Then, from gvim-32bit, :python3 import pynvim would complain about greenlet not being installed. However, from gvim-32bit still, running :terminal then from this cmd run python3 then import pynvim would work fine !

After reading some forums, I realised that greenlet is probably some native code, and as such has to be the correct architecture. Even if this is wrong, I installed gvim-64bit instead, and now everything is good, all good.

Maybe none on the maintainers of this amazing lib is in my situation, but I though it would help other users like me (for example futur me).
You may close this issue if there is nothing more to add.

Best,

echo neovim_rpc#serveraddr() returns /var/folders/4q/zfgdfzzzzdzzzzzdfgzgzgzzg, so i don’t think it worked right

The problem with TCP is that the port is exposed and a malicious app can listen and write to it.
Are there plans to provide alternative protocol such as named pipes.

When I install NCM and vim-hug-neovim-rpc, cm_start.py is being opened endlessly in new instances of Vim.

I am on Arch, and a few days ago after a huge list of python-[X] packages popped up in an update I started receiving the following error in vim when going into insert mode .. ( no errors on launch )

I have re-performed the install/setup process I originally did but has no impact... figure I would try and ask here while I continue to scratch my head and figure it out ;-)

Hello,
Not the fault of neovim-rpc.
I am trying to get this working on a chromebook running ChromeOS under Termux.
When executing "echo neovim_rpc#serveraddr()", I get:
~
[No Name] 0,0-1 All
Error detected while processing function neovim_rpc#serveraddr:

Is there a way I can work around this, do I need to rewrite the call to getaddrinfo() so that its compatible?

Thanks for any pointers you can give me.

I cannot seem to get this plugin to work. Below is some system information:

It should be noted that importing pynvim through standard python3 shell works without errors. But when I try to import pynvim through vim, this error happens:

I have multiple python virtual environments installed on my pc, but I don't want to install pynvim in all of them.

Would it be possible to specify a certain path to an python executable that has this module installed, instead of letting vim search in the PATH for the first python executable it can find?

vim-node-rpc author posted an article that claims vim-node-rpc is faster than this plugin

But I can't agree with that if I don't understand why it's faster.

I build a ubuntu 17.10 based docker image for easier reproducing the test. The result doesn't shows that vim-node-rpc is faster. On the contrary, it gets slower when the data gets bigger.

Hi, I'm considering using stdio to communicate with the Python process, to avoid security issues I've talked about in #1. What do you think about this idea?

PS: Firefox uses stdio for extensions to communicate with its native application too.

The example is defx error message in Vim8.

I have python 3.7.4 (default, Jul 16 2019, 07:12:58)

The attached log looks like it doesn't even try pynvim, but just goes straight to neovim.

:python3 import pynvim does the same. So I'm not sure what is going on.

Could you implement the feature?

I have installed neovim via pip install neovim, and in vim the command :python import neovim has no errors. However, when I opened the vim, it reported that No module named 'neovim'.

Warning: I will close the issue without the minimal init.vim and the reproduction instructions.

Problems summary

An error occurs attempting to use deoplete on Vim8.

[vim-hug-neovim-rpc] Vim(python3):Traceback (most recent call last):
Error detected while processing function deoplete#enable[1]..deoplete#initialize[1]..deoplete#init#_initialize[17]..deoplete#init#_variables[12]..neovim_rpc#serveraddr:

E605: Exception not caught: [vim-hug-neovim-rpc] requires :python3 import neovim command to work
Press ENTER or type command to continue

Expected

After following installation instructions, installing the plugins and performing the following commands

pip3 install neovim
python3 -c 'import neovim'

and seeing that both succeed, there should not be error messages saying that python3 can not import neovim.

Environment Information

I am using asdf-vm as a version manager, with python 3.6.1 installed on an Ubuntu 17.04 system.

" Minimal .vimrc to reproduce issue
call plug#begin()
  Plug 'Shougo/deoplete.nvim'

let g:deoplete#enable_at_startup = 1

The reproduce ways from neovim/Vim starting (Required!)

This error occurs on startup/attempting to enable deoplete

I actually have a workaround, and I'm not entirely sure where the fix really lies. However, since the error mentions that it's vim-hug-neovim-rpc that requires a command to succeed, that appears to succeed from the terminal, I figured I'd start here.

The issue appears to be caused that vim-hug-neovim-rpc when it attempts to require packages is not able to find the correct site-packages folder. If I manually export PYTHONPATH to the correct path, deoplete loads successfully. It seems that setting PYTHONPATH is usually not recommended, and it doesn't seem to be required for any other commands on my system for python3 and pip3 to work successfully.

export PYTHONPATH="~/.asdf/installs/python/3.6.1/lib/python3.6/site-packages"

Appears to be a temporary fix, is there a better solution to this?

I'm on Fedora 33 with Python 3.9. It works just fine with every project that uses explicitly python3.9 or implicit python(3)?, both with and without a virtual environment.

However, I do have a project that requires 3.7 and won't run on newer versions and I'd like to keep using awesome python-language-server and asynchronous deoplete as regular synchronous jedi tends to block the whole editor's thread with bigger libraries like SQLAlchemy, but some of plugins just won't let me.

Sure thing I did install neovim and pynvim packages in my virtual environment.
echo exepath('python3') returns /home/euromancer/source/airflow/.venv/bin/python3 and has('pythonx') returns 1, however, has('python') returns 0. Nothing mysterious in my vimrc, just lsp#register_server() and few configs for lsp. Nothing special on deoplete as well.

I've quickly checked the source code, however, I'm not very familiar with vimscript nor vim plugins nor probably anything. Although I think it might be linked to list of python executables to check availability.

Sure thing all the packages and plugins and everything (except Python 3.7 lol) are up to date.

My completion-related plugins are:

• Shougo/deoplete.nvim
• prabirshrestha/vim-lsp
• lighttiger2505/deoplete-vim-lsp

And I do have roxma/nvim-yarp and roxma/vim-hug-neovim-rpc.

Never tested it with neovim tho, as I prefer vim for some whatever reasons I find hard to point out.

I did install neovim and pynvim and python-language-server on the global Python 3.7 installation.

The issue was present on Ubuntu 20.04 with Python 3.8 too.

Ubuntu 18.04 & Vim 8, trying to use ncm2, ncm-R, and Nvim-R for R development. As for vim-hug-neovim-rpc, when I ran :echo neovim_rpc#serveraddr(), didn't get the address but "/tmp/vPac7C8/0" instead. What does it mean and is it the reason for ncm not working?

FYI, I can run neovim in python3. :echo has('python3') returns 1.

Thanks, appreciate your time!

in neovim has('python') and has('python3') both return 1, and I install the client via pip install --user neovim and pip3 install --user neovim.

this plugin use pythonx by default, I think it will cause some issue:

if has('pythonx')
	let s:py = 'pythonx'
	let s:pyeval = function('pyxeval')
elseif has('python3')
	let s:py = 'python3'
	let s:pyeval = function('py3eval')
else
	let s:py = 'python'
	let s:pyeval = function('pyeval')
endif

in my pc, has('pythonx') return 1, and pyxversion=3 bydefault, then I can not use python2 remote plugin, BTW, if I want to use python2 remote plugin and python3 remote plugin at the same time, how should I do?

I will try to fix this issue, and send some PRs. test will be done in SpaceVim/SpaceVim#994

Im on Vim 8.1:

Following statements are true:

has('pythonx')
has('python')
has('python3')

neovim seem to be installed correctly:

Python 2.7.15 (default, May  1 2018, 20:16:04) 
[GCC 7.3.1 20180406] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import neovim
>>> 

Python 3.6.5 (default, May 11 2018, 04:00:52) 
[GCC 8.1.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import neovim
>>> 

When i open vim i get this error:

[vim-hug-neovim-rpc] failed executing: pythonx import neovim
[vim-hug-neovim-rpc] Vim(pythonx):Traceback (most recent call last)

As cfg i have:

" Deoplete
set pyxversion=3
set encoding=utf-8
let g:python_host_prog = "/usr/bin/python2"
let g:python3_host_prog = "/usr/bin/python3"
let g:deoplete#enable_at_startup = 1

Plugin 'roxma/nvim-yarp'
Plugin 'roxma/vim-hug-neovim-rpc'
Plugin 'Shougo/deoplete.nvim'

First I posted it to deoplete Shougo/deoplete.nvim#616 but I was said issue caused by this plugin.

Problems summary

Deoplete cann't start and :call deoplete#enable() produces error:

_channel[21]..neovim_rpc#_on_stderr, line 2

Expected
