branch: master
commit 806e04b315283a6d3fdffb7ff45eec78a3ca6dbe
Author: Oleh Krehel <address@hidden>
Commit: Oleh Krehel <address@hidden>
Don't clutter Echo Area
* lv.el (lv-wnd): New variable.
(lv-window): New defun to get a window similar in properties to Echo Area.
(lv-message): New defun, a replacement for `message', that writes to
`lv-window'.
* hydra.el (hydra-lv): New defcustom. If nil, use the Echo Area,
otherwise, use LV.
(hydra-disable): Add optional arg KILL-LV.
(hydra--message): New defun to dispatch on `hydra-lv'.
(hydra--make-defun): Prematurely disable with LV only for blue heads,
since regenerating LV window would cause screen tearing. No need for
timeouts between `message' when using LV. HINT argument is now a
function symbol that returns a string, instead of a plain string.
(defhydra): Generate a new defun with name `NAME/hint'.
* Makefile: Load lv.
* hydra-test.el: Update all tests.
* README.md: Update.

+## Define Hydra heads that don't show up in the hint at all
+
+This can be done by setting the head's hint explicitly to `nil`, instead of
the usual string.
+
+## Use a dedicated window for Hydra hints
+
+Since version `0.10.0`, setting `hydra-lv` to `t` (the default setting) will
make it use a dedicated
+window right above the Echo Area for hints. This has the advantage that you
can immediately see
+any `message` output from the functions that you call, since Hydra no longer
uses `message` to display
+the hint. You can still have the old behavior by setting `hydra-lv` to `nil`.
