Python

There are two options for setting up a language server with Python:

• Microsoft Python Language Server (MPLS)- maintained by Microsoft
• pyls - maintained by Palantir

MPLS

Installation

Install MPLS from the repo: https://github.com/Microsoft/python-language-server

If you are using Arch, there are two AUR packages that can be found here:

• microsoft-python-language-server
• microsoft-python-language-server-git

Configuration

Add the following line to your .vimrc:

let g:LanguageClient_serverCommands = {
    'python' : ['dotnet', 'exec', '<path-to-mpls-installation>/Microsoft.Python.LanguageServer.dll'],
}

Next add the following to .vim/settings.json:

{
  "enabled": true,
  "initializationOptions": {
    "displayOptions": {
      "preferredFormat": "plaintext",
      "trimDocumentationLines": true,
      "maxDocumentationLineLength": 0,
      "trimDocumentationText": true,
      "maxDocumentationTextLength": 0
    },
    "interpreter": {
      "properties": {
        "InterpreterPath": "<path-to-python-executable>",
        "UseDefaultDatabase": true,
        "Version": "<python-version>"
      }
    }
  }
}

pyls

This section intentionally left blank as the author has no experience setting this up. If someone who has used pyls with this plugin can add the configuration here, that would be appreciated.
