Following are the snippets in my init.el
relevant to Flymake:
(add-hook 'python-mode-hook
(lambda ()
(unless (eq buffer-file-name nil) (flymake-mode 1)) ;dont invoke flymake on temporary buffers for the interpreter
(local-set-key [f2] 'flymake-goto-prev-error)
(local-set-key [f3] 'flymake-goto-next-error)
(local-set-key [f4] 'flymake-display-err-menu-for-current-line)
(hs-minor-mode)
(orgtbl-mode)
(outline-minor-mode -1)))
...
;;===== 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 "pychecker" (list local-file))))
(add-to-list 'flymake-allowed-file-name-masks
'("\\.py\\'" flymake-pyflakes-init)))
(mapcar (lambda (hook) (add-hook 'find-file-hook hook))
(list 'flymake-find-file-hook))
(unload-feature 'flymake) ; unloaded in an attempt to get rid of the error
But everytime I find-file
or revert-buffer
(extensions .xml
, .php
, .html
) I get the following error (not with .py
):
Flymake: Failed to launch syntax check process 'php' with args (-f _posteddata_flymake.php -l): Searching for program: permission denied, php. Flymake will be switch OFF
or
Flymake: Failed to launch syntax check process 'xml' with args (val //path/to/file/config/prod-conf_flymake.xml): Searching for program: permission denied, xml. Flymake will be switch OFF
I've also tried doing (load "flymake" nil)
but it didn't work either.
A big time sink when opening or reloading a big hunk of files.
How can I fix it?
Just don't add Flymake to find-file-hook
. Instead only add it to the hooks of major modes, you'd like to use it in.
You may also want to look at the alternative Flycheck package, which is safer to enable globally, supports more languages, and needs much less customization. Disclaimer: I'm the author of this package.
