Anju uses the customizable hook variable anju-reconfigure-main-menu-hook to customize the main menu bar.
anju-reconfigure-main-menu-hook is a list of hook functions, where each function is designed to modify a different menu of the main menu bar (e.g. “File”, “Edit”, “Options”, etc.). This hook is run in the command anju-init.
Detailed below are the different hook functions provided for by Anju.
Users are free to implement their own hook functions to add to anju-reconfigure-main-menu-hook. Users who wish to do this should familiarize themselves with menu keymaps (elisp#Menu Keymaps) and the Easy Menu (elisp#Easy Menu) library.
Note that Anju’s implementation of hook functions to each affect a specific menu in the main menu bar is by convention.
