To enable flymake for python, insert the following into your .emacs ::
|
|
|
|
;; Configure flymake for python
|
|
(setq pylint "epylint")
|
|
(when (load "flymake" t)
|
|
(defun flymake-pylint-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 (expand-file-name pylint "") (list local-file))))
|
|
(add-to-list 'flymake-allowed-file-name-masks
|
|
'("\\.py\\'" flymake-pylint-init)))
|
|
|
|
;; Set as a minor mode for python
|
|
(add-hook 'python-mode-hook '(lambda () (flymake-mode)))
|
|
|
|
Above stuff is in pylint/elisp/pylint-flymake.el, which should be automatically
|
|
installed on debian systems, in which cases you don't have to put it in your .emacs file.
|
|
|
|
Other things you may find useful to set ::
|
|
|
|
;; Configure to wait a bit longer after edits before starting
|
|
(setq-default flymake-no-changes-timeout '3)
|
|
|
|
;; Keymaps to navigate to the errors
|
|
(add-hook 'python-mode-hook '(lambda () (define-key python-mode-map "\C-cn" 'flymake-goto-next-error)))
|
|
(add-hook 'python-mode-hook '(lambda () (define-key python-mode-map "\C-cp" 'flymake-goto-prev-error)))
|
|
|
|
|
|
Finally, by default flymake only displays the extra information about the error when you
|
|
hover the mouse over the highlighted line. The following will use the minibuffer to display
|
|
messages when you the cursor is on the line.
|
|
|
|
;; To avoid having to mouse hover for the error message, these functions make flymake error messages
|
|
;; appear in the minibuffer
|
|
(defun show-fly-err-at-point ()
|
|
"If the cursor is sitting on a flymake error, display the message in the minibuffer"
|
|
(require 'cl)
|
|
(interactive)
|
|
(let ((line-no (line-number-at-pos)))
|
|
(dolist (elem flymake-err-info)
|
|
(if (eq (car elem) line-no)
|
|
(let ((err (car (second elem))))
|
|
(message "%s" (flymake-ler-text err)))))))
|
|
|
|
(add-hook 'post-command-hook 'show-fly-err-at-point)
|
|
|
|
|
|
Alternative, if you only wish to pollute the minibuffer after an explicit flymake-goto-* then use
|
|
the following instead of a post-command-hook
|
|
|
|
(defadvice flymake-goto-next-error (after display-message activate compile)
|
|
"Display the error in the mini-buffer rather than having to mouse over it"
|
|
(show-fly-err-at-point))
|
|
|
|
(defadvice flymake-goto-prev-error (after display-message activate compile)
|
|
"Display the error in the mini-buffer rather than having to mouse over it"
|
|
(show-fly-err-at-point))
