This package exposes a number of utility hooks and functions ported from Doom Emacs. The hooks make it easier to speed up Emacs startup by providing finer-grained control of the timing at which packages are loaded.
For example, use-package users can delay loading the which-key
package until the first key is pressed:
(use-package which-key
:hook (on-first-input . which-key-mode))The list of hooks provided by on.el is as follows:
on-first-input-hook: run before the first user input.on-first-file-hook: run before the first interactively opened file.on-first-buffer-hook: run before the first interactively opened buffer.on-init-ui-hook: run when the UI has been initialized. This one is useful for setting fonts and enabling custom themes without having to worry about whether Emacs is running as a daemon or not.
