Method: HookApp#select_hook

Defined in:
lib/hook/hookapp.rb

#select_hook(marks) ⇒ Object

Generate a menu of available hooks for selecting one or more hooks to operate on. Revamped to use ‘fzf`, which is embedded as `lib/helpers/fuzzyfilefinder` to avoid any conflicts. Allows multiple selections with tab key, and type-ahead fuzzy filtering of results.
