@Name Indirect buffers wouldn't help, because what's special isn't the *Messages* buffer, but the code that inserts the messages into it.

@phils Advising message wouldn't work for messages emitted by primitives. It would be risky for what is probably the reason that no hook fires when a message is emitted: any error or other message emitted from that advice/hook would cause recursion, so you'd need to be careful and disable the hook (like post-command-hook) in case this happens.

Can indirect buffers help? gnu.org/software/emacs/manual/html_node/emacs/… I mean to create a clone or indirect clone of the buffer message and fire the hook on that clone?

Question is as-is. I'm trying to avoid the XY problem, but in this case I want to know the answer to this specific question. I am not trying to debug anything, and I do not want to advise message. I want to be able to fire a function whenever the contents of *Messages* change. I appreciate your efforts in trying to solve my root problem and will consider whether there is a better way to contextualize the problem. I believe this question in its current state is unambiguously answerable according to SX guidelines, and I want to be careful about adding more information.

There is no such hook. You could advise message, but it's not clear whether that's sufficient, or sensible. If you're trying to debug something, use the debug-on-message variable (available since 24.3).
