Emacs functions for setting multiple hooks.
Typically, you would need to call add-hook
multiple times with
similar arguments to declare multiple functions for one hook, or
vice versa. add-hooks-pair
is a variant that takes multiple
hooks or functions that apply to each other. The add-hooks
function tidies up duplicate hook and function names further into a
single declarative call (inspired by the
bind-key
package).
If you're using use-package
, use its :hook
keyword instead, which has a
similar syntax while establishing autoload definitions and supporting
deferred loading.
Call add-hook
for each combined pair of items in HOOKS and FUNCTIONS.
HOOKS can be a symbol or a list of symbols representing hook
variables (the -hook
suffix is implied). FUNCTIONS can be a
symbol, a lambda, or a list of either representing hook
functions. If lists are used, a function can be added to
multiple hooks and/or multiple functions can be added to a hook.
ELISP> (add-hooks-pair '(css-mode sgml-mode) 'emmet-mode)
nil
ELISP> css-mode-hook
(emmet-mode)
ELISP> sgml-mode-hook
(emmet-mode)
Call add-hooks-pair
on each cons pair in PAIRS.
Each pair has a car
for setting hooks and a cdr
for setting
functions to add to those hooks. Pair values are passed to the
HOOKS and FUNCTIONS arguments of add-hooks-pair
, respectively.
(add-hooks ((HOOKS . FUNCTIONS)...))
ELISP> (add-hooks '(((css-mode sgml-mode) . emmet-mode)))
nil
