Every major mode function should finish by running its mode hook and the
mode-independent normal hook after-change-major-mode-hook. It does
this by calling run-mode-hooks. If the major mode is a derived mode,
that is if it calls another major mode (the parent mode) in its body, it
should do this inside delay-mode-hooks so that the parent won't run
these hooks itself. Instead, the derived mode's call to
run-mode-hooks runs the parent's mode hook too. Voir la section Major Mode Conventions.
Emacs versions before Emacs 22 did not have delay-mode-hooks. When
user-implemented major modes have not been updated to use it, they won't
entirely follow these conventions: they may run the parent's mode hook too
early, or fail to run after-change-major-mode-hook. If you encounter
such a major mode, please correct it to follow these conventions.
When you defined a major mode using define-derived-mode, it
automatically makes sure these conventions are followed. If you define a
major mode “by hand,” not using define-derived-mode, use the
following functions to handle these conventions automatically.
Major modes should run their mode hook using this function. It is similar
to run-hooks (voir la section Hooks), but it also runs
after-change-major-mode-hook.
When this function is called during the execution of a
delay-mode-hooks form, it does not run the hooks immediately.
Instead, it arranges for the next call to run-mode-hooks to run them.
When one major mode command calls another, it should do so inside of
delay-mode-hooks.
This macro executes body, but tells all run-mode-hooks calls
during the execution of body to delay running their hooks. The hooks
will actually run during the next call to run-mode-hooks after the
end of the delay-mode-hooks construct.
This is a normal hook run by run-mode-hooks. It is run at the very
end of every properly-written major mode function.
