* hydra.el (hydra-face-red): New face.
(hydra-face-blue): New face.
(hydra--color): Each head now has a color: red is persistent, blue is
single-use. Head color inherits body color if it's not explicitly
overridden. Body color is red unless explicitly stated.
(hydra--face): Return face that corresponds to color.
(hydra--hint): New function, moved out of `defhydra'.
(hydra-disable): New function, moved out of `defhydra'.
(hydra--doc): New function, moved out of `defhydra'.
(defhydra): Commands that will vanquish the Hydra should be colored with
`hydra-face-blue'. The ones that will make the Hydra persist should be
colored with `hydra-face-red'.
Add autoload, move some code outside, Test HEAD's second element with
`null' instead of `functionp'.
* hydra-test.el (defhydra-red-error): Rename from `defhydra'.
(hydra-blue-toggle): Add test.
* README.md: Update.
Example:
(global-set-key
(kbd "C-c C-v")
(defhydra toggle ()
"toggle"
("t" toggle-truncate-lines "truncate" :color blue)
("f" auto-fill-mode "fill" :color blue)
("a" abbrev-mode "abbrev" :color blue)
("q" nil "cancel")))
Alternatively, since heads inherit color from the body:
(global-set-key
(kbd "C-c C-v")
(defhydra 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")))
* hydra.el (hydra-create): Expects a lists of lists for HEADS, instead
of list of cons cells. The optional thrid element of each list is the
hint.
* hydra-examples.el: Update the examples.
* README.md: Update.
Re #2
* hydra.el (hydra-create): Add a third optional argument. When it's not
supplied, the behavior should remain the same. Otherwise, it's a
lambda that's used instead of `global-set-key', with the same semantics.
* README.md: Update.
re #1
