27 ;; Provides support for editing GNU CFEngine files, including
28 ;; font-locking, Imenu and indentation, but with no special keybindings.
30 ;; By default, CFEngine 3.x syntax is used.
32 ;; You can set it up so either `cfengine2-mode' (2.x and earlier) or
33 ;; `cfengine3-mode' (3.x) will be picked, depending on the buffer
36 ;; (add-to-list 'auto-mode-alist '("\\.cf\\'" . cfengine-auto-mode))
38 ;; OR you can choose to always use a specific version, if you prefer
41 ;; (add-to-list 'auto-mode-alist '("\\.cf\\'" . cfengine3-mode))
42 ;; (add-to-list 'auto-mode-alist '("^cf\\." . cfengine2-mode))
43 ;; (add-to-list 'auto-mode-alist '("^cfagent.conf\\'" . cfengine2-mode))
45 ;; It's *highly* recommended that you enable the eldoc minor mode:
47 ;; (add-hook 'cfengine3-mode-hook 'eldoc-mode)
49 ;; You may also find the command `cfengine3-reformat-json-string'
50 ;; useful, just bind it to a key you prefer. It will take the current
51 ;; string and reformat it as JSON. So if you're editing JSON inside
52 ;; the policy, it's a quick way to make it more legible without
53 ;; manually reindenting it. For instance:
55 ;; (global-set-key [(control f4)] 'cfengine3-reformat-json-string)
57 ;; This is not the same as the mode written by Rolf Ebert
58 ;; <ebert@waporo.muc.de>, distributed with cfengine-2.0.5. It does
59 ;; better fontification and indentation, inter alia.
