No hover information

[YosufE]

I am having Troubles with the hover informations. Followed installation instructions, but it still doesnt want to work like in this screenshot: https://user-images.githubusercontent.com/5492542/57384333-019b9880-71e3-11e9-9ee8-7e731944777b.png What am i doing wrong? Here are my files minimal init.vim: ` call plug#begin()

" Autocomplete Plug 'neoclide/coc.nvim', {'do': 'yarn install --frozen-lockfile'} Plug 'Shougo/neco-vim' Plug 'neoclide/coc-neco'

set completeopt=noinsert,noselect,menuone

minimal coc-settings.json:

` { "languageserver": { "digestif": { "command": "digestif", "filetypes": ["tex", "plaintex", "context"] } },

"vimlsp.debug": {
  "type": "boolean",
  "default": false,
  "description": "enable coc-vimlsp service debug"
},
"vimlsp.diagnostic.enable": {
  "type": "boolean",
  "default": true,
  "description": "enable diagnostic"
},
"vimlsp.trace.server": {
  "type": "string",
  "default": "off",
  "enum": [
    "off",
    "messages",
    "verbose"
  ],
  "description": "Trace level of vim language server"
}

} `

sorry for the bad formatting i dont know why its like that

The screenshot is signature help not hover document.

remove

Plug 'Shougo/neco-vim'
Plug 'neoclide/coc-neco'

if you want to use hover document, modify your s:show_documentation function to use lsp.

[bratekarate]

Can you please elaborate what you mean with modyfying the function? What is the right way to make use of vimlsp hover? I tried the following:

function! s:CocShowDocumentation()
    call CocAction('doHover')
endfunction

It does not work.

:CocInfo output for the hover request:

[Trace - 6:22:16 PM] Sending request 'textDocument/hover - (3)'.

    "textDocument": {

    }
}

So there is a response, but it seems to be a bug with the hover display. Or if it's not a bug, what is configured wrong? Hovers of other langauge servers work for me.

Make sure your neovim or vim support floating windows.

[bratekarate]

My neovim supports floating windows. I never said floating windows are an issue. This issue is only about onHover with coc-vimlsp

I tried to disable floating windows with "coc.preferences.hoverTarget": "echo". Same result, nothing happens only with vimlsp.

Is my ShowDocumentation function right? Can you compare it with the configuration used to make the screenshots?

Edit: The issue occurs only with the latest coc version (release). I downgraded to coc v0.0.78 and it works. Should I rather create an issue there?

[iamcco]

I see, it send the hover document request and receive response but the document window do not show. seems coc.nvim have change something.

[iamcco]

I have create a new issue https://github.com/iamcco/coc-vimlsp/issues/20, and will update info there.

[bratekarate]

Thank you for checking on this issue. Really like to use coc-vimlsp, all other features work great.

Edit: wow, already fixed? Thanks, did not expect that!
