Servers Python

python-language-server

A Python 2.7 and 3.4+ implementation of the Language Server Protocol.

Installing server

pip install python-language-server

Once the python-language-server is installed, you can either:

1. Install vim-lsp-python OR
2. Register the python-language-server yourself in your .vimrc

Installing vim-lsp-python

If you'd like the vim-lsp-python plugin to register the python-language-server for you, install the vim-lsp-python plugin:

" After vim-lsp, etc
Plug 'ryanolsonx/vim-lsp-python'

Registering in .vimrc

if executable('pyls')
    au User lsp_setup call lsp#register_server({
        \ 'name': 'pyls',
        \ 'cmd': {server_info->['pyls']},
        \ 'whitelist': ['python'],
        \ })
endif

Workspace Configuration

python-language-server has several settings that can be tweaked through the workspace configuration. For example, enabling pydocstyle (which is disabled by default):

if executable('pyls')
    au User lsp_setup call lsp#register_server({
        \ 'name': 'pyls',
        \ 'cmd': {server_info->['pyls']},
        \ 'whitelist': ['python'],
        \ 'workspace_config': {'pyls': {'plugins': {'pydocstyle': {'enabled': v:true}}}}
        \ })
endif

The full set of options that can be manipulated can be found in package.json.
