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"))
