6 @appendix Standard Hooks
8 @cindex hook variables, list of
10 The following is a list of some hook variables that let you provide
11 functions to be called from within Emacs on suitable occasions.
13 Most of these variables have names ending with @samp{-hook}. They are
14 @dfn{normal hooks}, run by means of @code{run-hooks}. The value of such
15 a hook is a list of functions; the functions are called with no
16 arguments and their values are completely ignored. The recommended way
17 to put a new function on such a hook is to call @code{add-hook}.
18 @xref{Hooks}, for more information about using hooks.
20 The variables whose names end in @samp{-functions} are usually @dfn{abnormal
21 hooks} (some old code may also use the deprecated @samp{-hooks} suffix); their
22 values are lists of functions, but these functions are called in a special way
23 (they are passed arguments, or their return values are used). The variables
24 whose names end in @samp{-function} have single functions as their values.
26 This is not an exhaustive list, it only covers the more general hooks.
27 For example, every major mode defines a hook named
28 @samp{@var{modename}-mode-hook}. The major mode command runs this
29 normal hook with @code{run-mode-hooks} as the very last thing it does.
30 @xref{Mode Hooks}. Most minor modes have mode hooks too.
32 A special feature allows you to specify expressions to evaluate if and
33 when a file is loaded (@pxref{Hooks for Loading}). That feature is
34 not exactly a hook, but does a similar job.
36 @c We need to xref to where each hook is documented or else document it here.
37 @c Add vindex for anything not indexed elsewhere.
38 @c This list is in alphabetical order, grouped by topic.
39 @c TODO It should probably be more thoroughly ordered by topic.
