Lsp Plugin for working with Python virtual environments

Overview

py_lsp.nvim

What is py_lsp?

py_lsp.nvim is a neovim plugin that helps with using the lsp feature for python development.

It tackles the problem about the activation and usage of python virtual environments for the nvim lsp.

Installation

Using vim-plug:

Plug 'HallerPatrick/py_lsp.nvim'

Using packer.nvim:

use {'HallerPatrick/py_lsp.nvim'}

Usage

Instead of initializing the server on your own, like in nvim-lspconfig, py_lsp is doing that for you.

Put this in your init.lua (or wrap in lua call for your init.vim)

require'py_lsp'.setup {
  -- This is optional, but allows to create virtual envs from nvim
  host_python = "/path/to/python/bin"
}

This minimal setup will automatically pass a python virtual environment path to the LSP client for completion/linting.

Features

py_lsp exposes several commands that help with a virtual env workflow.

Command Parameter Usage
:PyLspCurrentVenv No Prints the currently used python venv
:PyLspDeactiveVenv No Shuts down the current LSP client
:PyLspReload No Reload LSP client with current python venv
:PyLspActivateVenv venv name Activates a virtual env with given name (default: 'venv'). This venv should lie in project root
:PyLspCreateVenv venv name Creates a virtual env with given name (default: 'venv'). Requires host_python to be set and have virtualenv installed
:PyRun command Run files and modules from current virtuale env

Most of these commands can be also run over a popup menu with :PyLspPopup.

Example Workflow

You open up your python project. Because there is no python virtual env confirgured, the LSP is not starting.

  1. You run :PyLspCreateVenv venv to create a new virtual env from host_python.
  2. You run :PyLspCurrentVenv to check if the LSP client is using your new venv.
  3. You run :PyRun -m pip install -r requirements.txt to install project dependencies.
  4. You run :PyLspReload so that the LSP client also find your new site-packages for autocompletion and correct linting.

You start programming!

Extras

The virtual environment path and name can be retrieved with client.config.settings.python.pythonPath and client.config.settings.python.venv_name. This can for example be used in your statuslines.

Example provider for feline:

local function lsp_provider(component)

    local clients = {}
    local icon = component.icon or ''

    for _, client in pairs(vim.lsp.buf_get_clients()) do
        if client.name == "pyright" then
          -- Check if lsp was initialized with py_lsp
          if client.config.settings.python["pythonPath"] ~= nil then
            local venv_name = client.config.settings.python.venv_name
            clients[#clients+1] = icon .. client.name .. '('.. venv_name .. ')'
          end
        else
          clients[#clients+1] = icon .. client.name
        end
    end

    return table.concat(clients, ' ')
end

This will give you a VSCode like status:

Statusline with LSP server and venv name

Configuration

The configurations are not sensible yet, and are suiting my setup. This will change.

Default:

Default Values:
    auto_source = true,
    language_server = "pyright",
    on_attach = nil,
    source_strategies = {"default", "poetry", "system"},
    capabilities = nil,
    host_python = nil

Todo

  • Support for different environment systems:
    • virtualenvwrapper
    • Conda
    • Pipenv

Limitations

  • All features are currently only available with pyright. pylsp is weird. It will still be started, but all features are run with a 'pyright' server or not at all.
  • py_lsp expects to find virtualenv in the cwd, please check for that

Note

This plugin is created due to following Issue.

This plugin currently includes a utility to automatically pass a virtualenv to the pyright lsp server before initialization also take from the Issue. (Thanks lithammer and others).

  • Add conda integration

    Add conda integration

    I noticed this is already on your todos, but it would be a really nice feature to see. It seems like you could integrate it pretty easily by searching the envs path at the conda installation location (usually something like ~/conda). I was able to follow the example here to create my own little change Python interpreter code:

    function change_python_interpreter(path)
        vim.lsp.stop_client(vim.lsp.get_active_clients())
        configs.pyright.settings.python.pythonPath = path
        require'lspconfig'.pyright.setup(configs.pyright)
        vim.cmd('e%')
    end
    
    function get_python_interpreters(a, l, p)
        local paths = {}
        local is_home_dir = function()
            return vim.fn.getcwd(0) == vim.fn.expand("$HOME")
        end
        local commands = {'fd --glob -tl python $HOME/mambaforge', 'which -a python', is_home_dir() and '' or 'find . -name python'}
        for _, cmd in ipairs(commands) do
            local _paths = vim.fn.systemlist(cmd)
            if _paths then
                for _, path in ipairs(_paths) do
                    table.insert(paths, path)
                end
            end
        end
        table.sort(paths)
        local res = {}
        for i, path in ipairs(paths) do
            if path ~= paths[i+1] then table.insert(res, path) end
        end
        return res
    end
    
    vim.api.nvim_exec([[
    command! -nargs=1 -complete=customlist,PythonInterpreterComplete PythonInterpreter lua change_python_interpreter(<q-args>)
    
    function! PythonInterpreterComplete(A,L,P) abort
      return v:lua.get_python_interpreters()
    endfunction
    ]], false)
    

    This provides a PythonInterpreter vim command which offers completion options of all conda environments and works well for me. However, I like what you are doing with this plugin much better.

    So when running this command I get this error image

    Doing some research (and editing my stratagies.lua the function table.unpack isn't available in older versions of lua info - any way I was able to fix it by removing the table.

    Is this something you want to fix ? or should we recommend users update there Lua to 5.2 ?

    Add completion.nvim plugin to Installation section in README

    Hey thanks for this plugin, it works great!

    When I installed this for the first time with Vim-Plug I did not know this plugin requires completion-nvim so the require("completion") part in options.lua caused an error when resourcing my init.vim file.

    Therefore, I added this to the Installation section :)

    Remove 'completion' from on_attach, add capabilities

    Hi, thanks for the plugin! I'm currently deciding on my Python workflow and this'll probably make the cut. :) I have two improvements to suggest:

    1. It seems unnecessary to demand the completion plugin. It only appears in the default on_attach setting and can be safely removed.
    2. It'd be good to also expose a capabilities field when passing options to require'lspconfig'.setup as that's where you turn on snippet support.

    Incompatible with LSP installed by LspInstall

    https://github.com/kabouzeid/nvim-lspinstall is a convenient plugin to install LSP servers. They end up in a separate directory outside of $PATH (~/.local/share/nvim/lspinstall/python/./node_modules/.bin/pyright-langserver in my case), but https://github.com/kabouzeid/nvim-lspinstall/blob/54b439241e83e0a9ce8f6bcdf3b2c560a2328792/lua/lspinstall.lua#L94 corrects the default cmd for lspconfig to point to that location. However py_lsp doesn't pick up on it for some reason, perhaps overriding cmd or cmd_cwd in default_config?

    This is with py_lsp installed and used to set up Pyright: image image

    And this is with py_lsp disabled: (note cmd) image
