vim coc support #55

Closed burner closed 4 years ago

burner commented 5 years ago

I tried getting vscode-dlang to work with neovim and coc using Plug to install it. Installing seemed to have worked as vscode-dlang was activated by neovim when opening an .d file. But dcd-server does not receive any completion requests.

It would be awesome if vscode-dlang would become a first class coc citizen.

vscode-dlang is the extension for VSCode, for coc you should use DLS directly. You can install it with:

dub fetch dls
dub run dls:bootstrap

Then you should be able to configure it in coc's configuration file with a custom language server definition. It should probably look like something like this:

"languageserver": {
    "d": {
      "command": "/home/burner/.dub/packages/.bin/dls-latest/dls", // this path should be printed with the previous commands
      "args": ["--stdio"],
      "filetypes": ["d"],
      "trace.server": "off",
      "rootPatterns": ["dub.json", "dub.sdl"],
      "initializationOptions": {
      },
      "settings": {
      }
    }
  }

Initialization options and settings are listed in README.md.

it seems to work on another project of mine.
