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
ELISP> css-mode-hook
(emmet-mode)
ELISP> sgml-mode-hook
(emmet-mode)
