Questions tagged [advice]

is for the Elisp advice feature that changes an existing definition of a function in a way that lets you undo the change easily. This tag applies to both old and new advice features. The old advice feature uses defadvice. The new advice feature uses functions and macros such as advice-add and add-function.

While the tag is properly spelled as the noun , the Emacs manuals and Stack Exchange questions also use advise(the verb form) and advising. Try these alternate spellings when searching.
