Flymake is a generic syntax checker for Emacs. Its combination with PyFlakes which is a syntax checker for python makes it a perfect setting for Python programming in Emacs. Here are the steps to make it to work:
1) Install PyFlakes:
- If you have python setuptools installed, just try
sudo easy_install pyflakes
- If you could not use the setuptools, you can also try using your distributions repositories. For Ubuntu/Debian you can try
sudo apt-get install pyflakes
2) Install Flymake:
- If you are using Emacs 23+, it is already included in your installation, follow to the next step.
- You can download it from here, and put it to your emacs directory under your home (usually, “~/.emacs.d” directory).
3) Copy the following to your “init.el” file, which is again located under your Emacs folder (e.g. “~/.emacs.d/init.el”):
;;===== PyFlakes ;; code checking via pyflakes+flymake (when (load "flymake" t) (defun flymake-pyflakes-init () (let* ((temp-file (flymake-init-create-temp-buffer-copy 'flymake-create-temp-inplace)) (local-file (file-relative-name temp-file (file-name-directory buffer-file-name)))) (list "pyflakes" (list local-file)))) (add-to-list 'flymake-allowed-file-name-masks '("\\.py\\'" flymake-pyflakes-init))) (add-hook 'find-file-hook 'flymake-find-file-hook)
