3.1 Flymake mode

Flymake is an Emacs minor mode. To use Flymake, you must first activate flymake-mode by using the flymake-mode function.

Instead of manually activating flymake-mode, you can configure Flymake to automatically enable flymake-mode upon opening any file for which syntax check is possible. To do so, place the following line in .emacs:

(add-hook 'find-file-hook 'flymake-find-file-hook)
