;; Configuration for hydra. Set it up to use posframe instead of the default lv.
;; Add the following to your init file in case you want to use this

;;     (with-eval-after-load 'hydra (require 'oni-hydra))

;;; Code:

(require 'hydra)
(require 'lv)
(require 'posframe)

(defun oni-hydra-custom-show (&rest args)
  "Use ‘hydra-posframe-show’ when possible, fall back to ‘lv-message’.
ARGS are passed on without modification."
  (if (posframe-workable-p)
      (apply #'hydra-posframe-show args)
    (apply #'lv-message args)))

(defun oni-hydra-custom-hide (&rest args)
  "Use ‘hydra-posframe-hide’ when possible, fall back to ‘lv-delete-window’.
ARGS are passed on without modification."
  (if (posframe-workable-p)
      (apply #'hydra-posframe-hide args)
    (apply #'lv-delete-window args)))
