LunarVim Advanced Pyright LSP Configuration & Usage | by chris@machine | Medium

May 4, 2023 - We’ll begin by overriding the pyright language server defaults that LunarVim ships with. While the defaults are probably fine for the average user, for this article we want to be in full control of the language server. vim.list_extend(lvim.lsp.automatic_configuration.skipped_servers, { "pyright" })

I tried your config, and it works for me. You can see the below figure. I faced an issue in using helm, so I disabled only the use-package declaration.

The relevant error is "npm because it is not present", which is what is used by lsp-mode or lsp-install-sever to install many language servers, including pyright. You can use the following link to install npm on your preferred OS (I am assuming Ubuntu).

How to Install Node.js and npm on Ubuntu 20.04

Note that you can also install pyright by yourself globally so that it is available in your $PATH. Then, lsp-mode clients will no longer try to install the server on your behalf. You can do either of the following:

npm install -g pyright 
# If you prefer snap: https://snapcraft.io/
sudo snap install pyright --classic

You can include additional Python source paths with lsp-pyright-extra-paths. Here is my pyrightconfig.json for a project.

{
  "exclude": ["**/node_modules", "**/__pycache__"],
  "ignore": ["**/node_modules", "**/__pycache__"],
  "include": ["flextensor", "tvm"]
  "pythonPlatform": "Linux",
  "pythonVersion": "3.6",
  "reportMissingImports": true,
  "reportMissingTypeStubs": false,
  "stubPath": "typings",
  "typeCheckingMode": "basic",
  "venvPath": "/home/swarnendu/tmp/virtualenvs",
  "venv": "flextensor-venv"
}

Here is my Emacs setup (init.el) for pyright (ignoring remote Tramp setup). You could also use use-package for this.

  (when (executable-find "pyright")
    (unless (fboundp 'lsp-pyright-locate-python)
      (autoload #'lsp-pyright-locate-python "lsp-pyright" nil t))
    (unless (fboundp 'lsp-pyright-locate-venv)
      (autoload #'lsp-pyright-locate-venv "lsp-pyright" nil t))

    (add-hook 'python-mode-hook (lambda ()
                                  (require 'lsp-pyright)
                                  (lsp-deferred)))

    (defvar lsp-pyright-python-executable-cmd)
    (setq lsp-pyright-python-executable-cmd "python3")))

Here is the .dir-locals.el for the same project.

(
 (python-mode . (
                 (pyvenv-activate . "/home/swarnendu/tmp/virtualenvs/flextensor-venv")
                 (eval . (let (
                               (paths
                                (vconcat (list
                                          (expand-file-name "flextensor" (projectile-project-root))
                                          (expand-file-name "tvm" (projectile-project-root))
                                          ))))
                           (setq lsp-pyright-extra-paths paths)))
                 ))
 )

Please check whether a similar setup works for you.

Have you checked if your pyrightconf.json file is actually found ?

You can check by skimming the log buffer for the lsp session

C-x C-b should give you a list of buffers

You can look for "window" as a keyword. In fact if the file is found or not is sent by the server in a "window" type message

If your conf file is found, than it's a matter of properly filling it in
If it's not, it's a matter of adding/removing roots from your lsp session (lsp-workspace-folder-add/remove)

r/emacs on Reddit: New(ish) Python LSP server which works with Emacs: basedpyright

January 24, 2025 -

A new to me LSP server for Python has appeared: basedpyright. This is a fork of the fast pyright langserver which Microsoft develops, with a more OSS philosophy. It has lots of improvements bringing it close to (and in some cases surpassing) the proprietary, MS VSCode-only LSP server pylance which wraps pyright:

Basedpyright is a fork of pyright with various type checking improvements, improved vscode support and pylance features built into the language server.

You can read about all the improvements over pyright. The one most meaningful to me is "docstrings for compiled builtin modules". E.g. docs with eglot go from:

pyright:

class range(
    stop: SupportsIndex,
    /
)

basedpyright:

class range(
    stop: SupportsIndex,
    /
)

range(stop) -> range object
range(start, stop[, step]) -> range object

Return an object that produces a sequence of integers from start (inclusive)
to stop (exclusive) by step.  range(i, j) produces i, i+1, i+2, ..., j-1.
start defaults to 0, and stop is omitted!  range(4) produces 0, 1, 2, 3.
These are exactly the valid indices for a list of 4 elements.
When step is given, it specifies the increment (or decrement).

Recent eglot versions already support it: just pip install basedpyright. Works fine with lsp-booster and all the normal settings.

I switched from python-lsp-server to basedpyright about a month ago and I really like it. I especially like the inlay code hints and auto import functionalities that basedpyright provide. I did disable basedpyright's type checker though since our CI/CD pipelines use ruff and mypy, which I use through flycheck (which I actually prefer above flymake).

I've used it for a while, I think it's great though when using the "recommended" typeCheckingMode it's a bit too strict. Typically when you have nested types (like nested dicts), it's a bit screamy. Otherwise I like it. I have this in my eglot config: (add-to-list 'eglot-server-programs '((python-mode python-ts-mode) "basedpyright-langserver" "--stdio")) I've installed it system wide with uv( https://github.com/astral-sh/uv ) (an all in one python version and package manager). Just do uv tool install basedpyright. I did a system install because I don't see the point re-installing it per-env unless I need a specific version. I try to use ruff-lsp at the same time but ( eglot doesn't support using multiple LSPs at the time ). An alternative is to use flymake-ruff as well.

I feel quite stupid now...But the reason why this didn't work is because I disabled pyright a long while ago:

'(lsp-disabled-clients '(pyright))

grep -lr .emacs.d pyright revealed it for me...
