LC Detects UltiSnips snippet manager https://github.com/autozimu/LanguageClient-neovim/blob/d690d2b62fb161266ccce15c3160760530f3c085/autoload/LanguageClient.vim#L36-L40 and creates snippets, that are listed in completion popup via deoplete, but upon completion it just inserts placeholders as text. See screenshots below: Just text completed function name: Now I selected [LC] source in the list: After completion confirm I left with plaintext placeholders inside function definition:

Reproduction

• neovim/vim version: NVIM v0.2.3-987-g2cbeb7ca5
• This plugin version: d690d2b
• This plugin's binary version: languageclient 0.1.68
• Minimal vimrc: minimalrc.txt
• File to try to reproduce: main.rs.txt
• Language server link and version: rls-preview 0.125.1-stable (cebf188 2018-03-19)
• Steps to reproduce the issue from clean state
  1. Download minimalrc.txt and main.rs.txt (you will need vundle to install plugins (sorry), and :UpdateRemotePlugins)
  2. Rename main.rs.txt to main.rs (damn github)
  3. nvim -u /path/to/minimalrc.txt /path/to/main.rs
  4. Try to call vaiv() inside main's body
     • type va, completion menu by deoplete pops up.
     • press Tab to complete vaiv's body
     • look at placeholders: vaiv(${1:a}, ${2:b})
• Logs. Paste or attach /tmp/LanguageClient.log and /tmp/LanguageServer.log. LanguageClient.log LanguageServer.log

Current Behavior

Expected Behavior

There were some disscussion about it here: https://github.com/Shougo/deoplete.nvim/issues/724#issuecomment-381312149 There currently discussion abut supporting LSP snippets in ultisnips here: https://github.com/SirVer/ultisnips/issues/964

Using the PHP language server from Roxma when the language server is enabled LanguageClientStart a single press of the d key delets a line.

Expected functionality is that a single press of the d key would not delete a line, instead, a double press would.

LangaugeClient log Does not seem to contain anything except for logs of files being parsed.

Hot on the heels of https://github.com/autozimu/LanguageClient-neovim/pull/1045#issuecomment-641455349, here's a way to use a selection UI other than FZF. The FZF selection UI is implemented as a special backwards-compatible version of the Funcref selection UI.

The function has to adhere to the arguments provided to s:FZF(), i.e. it has to take source and a sink arguments. As in fzf#run(), source can be either a list or a string, and sink may be a string or a reference to another function of one argument (the selected line).

In action, using vim-clap instead of FZF:

Config:

function! MySelectionUI(source, sink) abort
	return clap#run({'id': 'LCN', 'source': a:source, 'sink': a:sink})
endfunction

let g:LanguageClient_selectionUI = function('MySelectionUI')

The completion candidate contains a snippet.

Describe the solution you'd like

Exclude snippets from completions.

Summary

It seems that LanguageClient-neovim does not work well with neosnippet for function arguments completion.

  1. Try to complete any function. For example, String::from in the rust.

Current Behavior

It will autocomplete String::from(${1:s}) with the cursor in the end of the line.

Expected Behavior

It should trigger neosnippet to expand each arguments in the function.

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

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

This is kinda like the opposite of #Call/#Notify.

I want to listen for a custom message called output and run a function when it's received. Is there a way to do that at the moment?

btw, this plugin is awesome and works out of the box with the PowerShell language server: https://github.com/powershell/powershelleditorservices/

So I have recently reinstalled my computer and ever since I haven't been able to get much useful stuff out of RLS. I went over the install guide a few times but I see nothing I could have missed. While syntax errors work sometimes, stuff like rename or goto never do. Until now I have just ignored it thinking that it might just be buggy right now but it has been bothering me a lot.

Any idea what I could try to make this work? Chances are the mistake is somewhere on my end, but I'd be glad if someone would still be able to help me out.

This PR should fix two diagnostic signs related issues:

• #758 If multiple diagnostic messages were reported on a single line, multiple signs would be added but only one of them would be removed after the errors were resolved. I think we can just use the most severe one and drop the others on one line.
• #765 Limitation on number of signs was dropped.

@mhuttner @PierreLeidbring @mburakov Mind helping verify if is this fix you issues?

Hi,

I have experimentally reimplemented a hover window for LanguageClient#textDocument_hover() with Neovim's new floating window feature.

Here is a screencast with Neovim 0.4.0-dev and macOS 10.12:

This PR is still work in progress. I have not added any tests yet and I think there are some discussion points as follows:

• There is no way to move cursor into float window so user cannot scroll the contents. Some mappings might be needed.
• There is no way to close float window by user (No command like :pclose is not provided at this point). I added functionality to close the floating window automatically when cursor is moved. But I'm not sure this behavior makes all users happy
• Some people may prefer preview window. Using floating window might be opt-in or opt-out
• CursorLine is used for highlighting the floating window, but I'm not sure it is a good choice to modify background color slightly for every colorscheme. The highlight color might be customizable

It seems like a lot of code has changed since the Next branch has become the defacto.

I'm trying to follow issue #139. I have written the following function to that end:

function! LoadYamlAnsibleConfig()
        let config = json_decode(system("cat ~/.config/nvim/yaml/ansible.json"))
        call LanguageClient#Notify('workspace/didChangeConfiguration', { 'settings': config })
endfunction

Debug log has the following output which make me think it is not working:

2018-03-22T18:12:13.944742362-06:00 INFO languageclient::vim - <= {"method": "workspace/didChangeConfiguration", "jsonrpc": "2.0", "params": {"settings": {"yaml.schemas": {"https://raw.github
usercontent.com/shaded-enmity/ansible-schema-generator/master/examples/ansible.json": "/*.yml"}}}}                                                                                             
2018-03-22T18:12:13.944911658-06:00 WARN languageclient::rpchandler - Unknown notification: "workspace/didChangeConfiguration"

I'm trying to integrate the followinglanguage server.

Any guidance is welcome. Another issue from the server is that no trigger characters are returned so registration with NCM fails.

2018-03-22T18:11:30.827249189-06:00 DEBUG languageclient::languageclient - LanguageClient: failed to register as NCM source!: ErrorImpl { code: Message("missing field `triggerCharacters`"
    ), line: 0, column: 0 }

Is your feature request related to a problem? Please describe.

Now the "preview window for hover" is shown in default location (top) and it was easily cause text moving. I hope we can add some configuration to make it shown in right or bottom.

Describe the solution you'd like

May be we can add some option to tweak the "command modifiers" for previewed window. Such as:

let g:LanguageClient_PreviewWindowCommandModifiers = "botright vertical"

What is the equivalent of this if I'm using init.lua file:

let g:LanguageClient_serverCommands = {
    \ 'rust': ['~/.cargo/bin/rustup', 'run', 'stable', 'rls'],
    \ 'javascript': ['/usr/local/bin/javascript-typescript-stdio'],
    \ 'javascript.jsx': ['tcp://127.0.0.1:2089'],
    \ 'python': ['/usr/local/bin/pyls'],
    \ 'ruby': ['~/.rbenv/shims/solargraph', 'stdio'],
    \ }

thanks

• Did you upgrade to latest plugin version? Yep
• Did you upgrade to/compile latest binary? Run shell command bin/languageclient --version to get its version number. Yep
• (Neovim users only) Did you check output of :checkhealth LanguageClient? N/A
• Did you check troubleshooting? Yep

Describe the bug

I'm unsure if this is a bug, or intended functionality. I can't seem to get diagnostics to render in a popup window (as in coc.nvim, which works in my vim client, if extremely slowly): they're echoed to the bottom of the page, with the majority of their contents cut-off. My vim client has popup functionality, and I use that for rendering documentation. If it's relevant, I'm running NixOS, and using the vimHugeX package for gvim.
