An Emacs flymake handler for syntax-checking Python source code using pyflakes or flake8.
These days you might be better served by flycheck.
If you choose not to use one of the convenient packages in Melpa and Marmalade, you'll need to add the directory containing flymake-python-pyflakes.el to your load-path, and then (require 'flymake-python-pyflakes). You'll also need to install flymake-easy.
Add the following to your emacs init file:
(require 'flymake-python-pyflakes) (add-hook 'python-mode-hook 'flymake-python-pyflakes-load) To use flake8 instead of pyflakes, add this line:
(setq flymake-python-pyflakes-executable "flake8") You can pass extra arguments to the checker program by customizing the variable flymake-python-pyflakes-extra-arguments, or setting it directly, e.g.
(setq flymake-python-pyflakes-extra-arguments '("--ignore=W806"))
