I installed NeoVim and dense-analysis/ale plugin with vim-plug.

All of those seems to be installed, as the commands starting with :ALE autocomplete in NeoVim.

Then I tried to install PYLS via

python3 -m pip install --user python-language-server

and enabled it in my init.vim file that you can read here :

# File .config/nvim/init.vim
call plug#begin('~/.config/nvim/plugged')
Plug 'dense-analysis/ale'
let g:ale_linters = {'python': ['pyls']}
let g:ale_fixers = {'python': ['black']}
let g:ale_lint_on_text_changed = 'never'
let g:ale_lint_on_insert_leave = 0
let g:ale_lint_on_enter = 0
let g:ale_completion_enabled = 1
call plug#end()

" Display
set number " show the line numbers
set cursorline " underline the current line
colorscheme koehler " use my preferred palette

" Syntax highlighting
syntax on

" Set tabs to have 4 spaces
set tabstop=4 " nb of spaces in a tab
set softtabstop=4
set shiftwidth=4 " nb of spaces when using << or >>
set expandtab " use spaces when pressing <tab>

" Input
set mouse=a

" Output
set fileformat=unix
set encoding=utf-8

The problem is : commands like ":ALEGoToDefinition" or ":ALEFindReferences" don't work.

I saw that PYLS need Jedi to provide those, so I installed Jedi too.

python3 -m pip install --user jedi

But there's no change.

Here's my :ALEInfo content :

:ALEInfo...
 Current Filetype: python
Available Linters: ['bandit', 'flake8', 'mypy', 'prospector', 'pycodestyle', 'pydocstyle', 'pyflakes', 'pylama', 'pylint', 'pyls', 'pyre', 'vulture']

Did I forget some steps ? Thanks you

  • You should probably install jedi using vim plug – eyal karni Aug 21 at 17:56
  • Do you mean the jedi-vim plugin ? I tried, but it's no use. It allows to get autocompletion of Jedi directly in Vim, but I want to get this autocompletion with PYLS using Jedi. And the commands I want (like :ALEGoToDefinition) still don't work. – lial_slasher Aug 22 at 13:48
  • Make sure you can import jedi and that pyls is accessible. And that you don't mix python2 and 3. Other than that, I don't know. – eyal karni Aug 22 at 20:49
  • I got Command History: (executable check - success) pyls at the end of my ALEInfo and >>> import jedi in Python3 works. – lial_slasher Aug 22 at 21:23
