Completion popup not showing up automatically anymore

[schiegl]

The completion menu does not popup automatically in any Language. I tried a simple python file

"".     # <-- popup should show up but doesn't

NeoVim: 0.2.0
Plugin: Last one that's working 2760b3f

LanguageServer.log - Only Python Language Server seems to throw an error. Others don't

ERROR - pyls.server - Language server exiting due to uncaught exception

LanguageClient.log - not verbose.

WARNING [MainThread] Unknown parameter key: rootPath

My .vimrc is just from the README. Deoplete + LanguageClient no special settings.

I couldn't reproduce with the provided information.

Please provide vimrc and reproduction steps.

[schiegl]

I didn't see you had changed the README.

With the new setup the Java LS doesn't work at all. This is the error I get in LanguageServer.log:

Error: Unable to access jarfile ~/.config/nvim/eclipse.jdt.ls/plugins/org.eclipse.equinox.launcher_1.4.0.v20161219-1356.jar

However the python error message in LanguageClient.log disappeared. But the problem is still the same. Completion does not show up automatically.

init.vim

call plug#begin('~/.config/nvim/plugged')

let g:LanguageClient_autoStart = 0
set omnifunc=LanguageClient#complete
let g:LanguageClient_diagnosticsEnable = 0

let g:deoplete#enable_at_startup = 1

There are really no reproduction steps. I just opened a .py file. Typed "". and this is where the completion pops up in the last working version but not the latest.

[autozimu]

There are too many issues in the provided setting.

Error: Unable to access jarfile ~/.config/nvim/eclipse.jdt.ls/plugins/org.eclipse.equinox.launcher_1.4.0.v20161219-1356.jar

It is your responsibility to make sure language server could be started with the provided commands. This clearly says there is something wrong with the jar file/path.

---

let g:LanguageClient_autoStart = 0

If you have this line, language server will not be started automatically when opening a file. Completion won't show up until you start server explicitly with :LanguageClientStart.

Again, with the provided setting and after command :LanguageClientStart, I could see the correct completion list.

You might need to either remove

let g:LanguageClient_autoStart = 0

or run the command explicitly. And you may also need to check your plugin installation, possibly remove and re-install.

---

There are definitely reproduction steps even in this simple case.

• Install plugins with provided vimrc nvim -u /tmp/vimrc +PlugInstall
• Start with empty file nvim -u /tmp/vimrc /tmp/sample.py
• Start typing "".

[schiegl]

It is your responsibility to make sure language server could be started with the provided commands. This clearly says there is something wrong with the jar file/path.

But why is there nothing wrong with the path in version: 2760b3f. This version of the plugin works.

Also I ran :LanguageClientStart explicitely like you suggested in the issue template. Also autostarting does not make a difference.

And you may also need to check your plugin installation, possibly remove and re-install.

Also did that.

[autozimu]

I see. For the java language server, I think the issue is caused by ~ in arguments not expanded. I will push a fix shortly to fix that.

---

For the python one, I really don't have any idea what's going wrong. Please try at least attach a log here.

[schiegl]

Have your tried deoplete? NCM shows the completion menu but not deoplete.

[autozimu]

Yes, I tested with the provided vimrc, which is using deoplete.

I have the same issue, i found the reason is this commit b85ff8e.
Before:

React[.] -> show all completions

After:

React[.] -> nothing
React.[h] -> [h]asOwnProperty

Look like i must type at least 1 character to show the completion.

I have similar problem:

$ cat ~/desktop/test_config.vim               
call plug#begin('~/.config/nvim/plugged')
Plug 'autozimu/LanguageClient-neovim', { 'branch': 'next', 'do': 'make release' }
Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }
call plug#end()

set nocompatible
set noswapfile
set hidden

let g:LanguageClient_loggingLevel = 'DEBUG'
let g:LanguageClient_serverCommands = {
    \ 'rust': ['rustup', 'run', 'nightly', 'rls'],
    \ }

$ cat src/lib.rs
pub fn foo() {
    //
}

open file:

nvim -u ~/desktop/test_config.vim src/lib.rs

and type in the function body:

String::

nothing happens. /tmp/LanguageClient.log doesn't have any textDocument/completion calls.
However when I press C-X C-O, I see completion results.

[dschuessler]

Same problem with php-language-server. Completion with <C-x><C-o> works. Autocompletion does not. See GIF.

It doesn't matter if I use deoplete or nvim-completion-manager. Neither does it matter if I use MacVim or Terminal Vim. Other completion sources work fine.

MacVim 8.0.1420
Vim 8.0.642

.vimrc

filetype plugin on
set omnifunc=syntaxcomplete#Complete

call plug#begin('~/.vim/plugged')

if has('nvim')
    Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }
else
    Plug 'Shougo/deoplete.nvim'
    Plug 'roxma/nvim-yarp'
    Plug 'roxma/vim-hug-neovim-rpc'
endif

Plug 'autozimu/LanguageClient-neovim', {'tag': 'binary-*-x86_64-apple-darwin'}
Plug 'roxma/LanguageServer-php-neovim',  {'do': 'composer install && composer run-script parse-stubs'}

call plug#end()

" Use deoplete
let g:deoplete#enable_at_startup = 1

" LanguageClient-neovim
let g:LanguageClient_serverCommands = {
    \'python' : ['pyls'],
    \'php' : ['php', '~/.vim/plugged/LanguageServer-php-neovim/vendor/bin/php-language-server.php']
    \ }

Should fix with a7e940c
