Hooks¶
A hook is a list of functions that are executed when certain events
happen. Hooks are modified with the Emacs function add-hook
.
Evil provides entry and exit hooks for all its states. For example,
when switching from normal state to insert state, all functions in
evil-normal-state-exit-hook
and evil-insert-state-entry-hook
are executed.
It is guaranteed that the exit hook will be executed before the entry hook on all state switches.
During the hook execution, the variables evil-next-state
and
evil-previous-state
contain information about the states being
switched to and from, respectively.
