major-mode-hydra: Unrecognized keyword mode-hydra in use-package

[jerrypnz]

Could you try adding :demand t and see if works for you?

(use-package major-mode-hydra
  :demand t
  :bind
  ("M-SPC" . major-mode-hydra))

major-mode-hydra needs to be requried before those keywords can be used. Without :demand t the package is not loaded immediately.

That works. I had not read the following in use-package docs:

NOTE: Pay attention if you set use-package-always-defer to t, and also use the :after keyword, as you will need to specify how the declared package is to be loaded: e.g., by some :bind. If you’re not using one of tho mechanisms that registers autoloads, such as :bind or :hook, and your package manager does not provide autoloads, it’s possible that without adding :demand t to those declarations, your package will never be loaded.
