My goal is to configure lsp in order to ignore warning messages for flycheck in Python version.

When lsp is not in use, flycheck reads from my ~/.pylintrc file in order to ignore warning messsages. But when I enable lsp-mode it does not ignore the warning messages that I set in ~/.pylintrc file.


(defun flycheck-python-setup ()
(require 'flycheck)
(require 'flycheck-mypy)
(add-hook 'after-init-hook #'global-flycheck-mode)
(add-hook 'after-init-hook #'global-flycheck-mode)
(add-to-list 'flycheck-disabled-checkers 'python-flake8)
(add-hook 'python-mode-hook
          (lambda ()
            (setq flycheck-python-pylint-executable "~/venv/bin/pylint")
            (setq flycheck-pylintrc "~/.pylintrc")
            (setq indent-tabs-mode  nil
                  python-indent-offset  4
                  tab-width         4)
            (let ((inhibit-message  t))
(use-package python :ensure nil)
(add-hook 'python-mode-hook #'flycheck-python-setup)
(flycheck-add-next-checker 'python-flake8 'python-pylint 'python-mypy)

Having following lines in order to enable lsp-mode, changes the result for helm-flycheck.

(add-hook 'python-mode-hook 'lsp)
(add-hook 'python-mode-hook #'lsp-deferred)

❯ cat ~/.pylintrc
disable=D100,  C0305, C0303, W291,  C0111, R0801, W0703, C0103,

Your python-lsp-server, named further pylsp as in lsp-pylsp.el file, can use pylint if it is enabled - you need the following code lines to be added to your lsp configuration block:

  ;; Adding pylint as linter for pylsp
  (require 'lsp-pylsp)
  (setq lsp-pylsp-plugins-pylint-enabled t)
  (setq lsp-pylsp-plugins-pylint-args ["--rcfile=/<absolute-path-to-home-dir/.pylintrc"]) ;; or path to your project.

Please note the lsp servers have their own checkers, and consequently when used, flycheck module should not be configured/used in any specific way - you should remove your posted configuration.

One note: your item D100 posted in your .pylintrc file belongs to flake8 - you may have a .flake8rc file in your path.

This can be corrected also at the lsp-pylsp level, see this: https://emacs-lsp.github.io/lsp-mode/page/lsp-pylsp/#lsp-pylsp-plugins-flake8-filename - configure the variable lsp-pylsp-plugins-flake8-ignore.

  • I have added (setq lsp-pylsp-plugins-flake8-ignore t) into my init file, as I understand that will ignore flake8rc file. Should I also make changes in ~/.config/flake8 file as well?

  • That variable is of type lsp-string-vector, which means you must write (setq-lsp-pylsp-plugins-flake8-ignore ["D100"]) - aka add to this list instead of .flake8rc file; but for other cases (aka if lsp is not in use) the error code should be also added in .flake8rc.

  • Everything works fine on my end, but I haven't define any setq-lsp-pylsp-plugins-flake8-ignore ["D100"]) (should I also put it into .emacs file? sorry I just get lost for this line), I just put everything into .pylintrc under disable= and I did not also create any flake8rc file.

  • I want to apply flycheck after each save. For that should I do flycheck-compile and select python-pylint?

    To remove the D100 error, add a ~/.pydocstyle file to your home dir, with the content: [pydocstyle] ignore = D100 . The same error is also generated by pylint, but with the code C0114, so you need to add this code to your .pylintrc file.
