ccmode: CC Hooks

 
 6.1 Hooks
 =========
 
 CC Mode provides several hooks that you can use to customize the mode
 for your coding style.  The main hook is ‘c-mode-common-hook’;
 typically, you’ll put the bulk of your customizations here.  In
 addition, each language mode has its own hook, allowing you to fine tune
 your settings individually for the different CC Mode languages, and
 there is a package initialization hook.  Finally, there is
 ‘c-special-indent-hook’, which enables you to solve anomalous
 indentation problems.  It is described in Other Indentation, not
 here.  All these hooks adhere to the standard Emacs conventions.
 
    When you open a buffer, CC Mode first initializes it with the
 currently active style (Styles).  Then it calls
 ‘c-mode-common-hook’, and finally it calls the language-specific hook.
 Thus, any style settings done in these hooks will override those set by
 ‘c-default-style’.
 
  -- Variable: c-initialization-hook
      Hook run only once per Emacs session, when CC Mode is initialized.
      This is a good place to change key bindings (or add new ones) in
      any of the CC Mode key maps.  Sample Init File.
 
  -- Variable: c-mode-common-hook
      Common hook across all languages.  It’s run immediately before the
      language specific hook.
 
  -- Variable: c-mode-hook
  -- Variable: c++-mode-hook
  -- Variable: objc-mode-hook
  -- Variable: java-mode-hook
  -- Variable: idl-mode-hook
  -- Variable: pike-mode-hook
  -- Variable: awk-mode-hook
      The language specific mode hooks.  The appropriate one is run as
      the last thing when you enter that language mode.
 
    Although these hooks are variables defined in CC Mode, you can give
 them values before CC Mode’s code is loaded—indeed, this is the only way
 to use ‘c-initialization-hook’.  Their values aren’t overwritten when CC
 Mode gets loaded.
 
    Here’s a simplified example of what you can add to your ‘.emacs’ file
 to do things whenever any CC Mode language is edited.  See the Emacs
 manuals for more information on customizing Emacs via hooks.  
 Sample Init File, for a more complete sample ‘.emacs’ file.
 
      (defun my-c-mode-common-hook ()
        ;; my customizations for all of c-mode and related modes
        (no-case-fold-search)
        )
      (add-hook 'c-mode-common-hook 'my-c-mode-common-hook)
