If not, see . + +;;; Commentary: +;; +;; This package can be used to tie related commands into a family of +;; short bindings with a common prefix - a Hydra. +;; +;; Once you summon the Hydra (through the prefixed binding), all the +;; heads can be called in succession with only a short extension. +;; The Hydra is vanquished once Hercules, any binding that isn't the +;; Hydra's head, arrives. Note that Hercules, besides vanquishing the +;; Hydra, will still serve his orignal purpose, calling his proper +;; command. This makes the Hydra very seamless, it's like a minor +;; mode that disables itself automagically. +;; +;; Here's an example Hydra, bound in the global map (you can use any +;; keymap in place of `global-map'): +;; +;; (defhydra hydra-zoom (global-map "") +;; "zoom" +;; ("g" text-scale-increase "in") +;; ("l" text-scale-decrease "out")) +;; +;; It allows to start a command chain either like this: +;; " gg4ll5g", or " lgllg". +;; +;; Here's another approach, when you just want a "callable keymap": +;; +;; (defhydra hydra-toggle (:color blue) +;; "toggle" +;; ("a" abbrev-mode "abbrev") +;; ("d" toggle-debug-on-error "debug") +;; ("f" auto-fill-mode "fill") +;; ("t" toggle-truncate-lines "truncate") +;; ("w" whitespace-mode "whitespace") +;; ("q" nil "cancel")) +;; +;; This binds nothing so far, but if you follow up with: +;; +;; (global-set-key (kbd "C-c C-v") 'hydra-toggle/body) +;; +;; you will have bound "C-c C-v a", "C-c C-v d" etc. +;; +;; Knowing that `defhydra' defines e.g. `hydra-toggle/body' command, +;; you can nest Hydras if you wish, with `hydra-toggle/body' possibly +;; becoming a blue head of another Hydra. +;; +;; If you want to learn all intricacies of using `defhydra' without +;; having to figure it all out from this source code, check out the +;; wiki: https://github.com/abo-abo/hydra/wiki.

Note that Hercules, besides vanquishing the +Hydra, will still serve his orignal purpose, calling his proper +command. This makes the Hydra very seamless, it's like a minor +mode that disables itself automagically. + +Here's an example Hydra, bound in the global map (you can use any +keymap in place of `global-map'): + + (defhydra hydra-zoom (global-map "") + "zoom" + ("g" text-scale-increase "in") + ("l" text-scale-decrease "out")) + +It allows to start a command chain either like this: +" gg4ll5g", or " lgllg". + +Here's another approach, when you just want a "callable keymap": + + (defhydra hydra-toggle (:color blue) + "toggle" + ("a" abbrev-mode "abbrev") + ("d" toggle-debug-on-error "debug") + ("f" auto-fill-mode "fill") + ("t" toggle-truncate-lines "truncate") + ("w" whitespace-mode "whitespace") + ("q" nil "cancel")) + +This binds nothing so far, but if you follow up with: + + (global-set-key (kbd "C-c C-v") 'hydra-toggle/body) + +you will have bound "C-c C-v a", "C-c C-v d" etc. + +Knowing that `defhydra' defines e.g. `hydra-toggle/body' command, +you can nest Hydras if you wish, with `hydra-toggle/body' possibly +becoming a blue head of another Hydra. + +If you want to learn all intricacies of using `defhydra' without +having to figure it all out from this source code, check out the +wiki: https://github.com/abo-abo/hydra/wiki. There's a wealth of +information there. Everyone is welcome to bring the existing pages +up to date and add new ones. + +Additionally, the file hydra-examples.el serves to demo most of the +functionality.
