Right, I think we should definitely start with just a way to use TAGS *instead* of the major mode's own system.
I've posted a tiny minor mode in the previous message that does this. Does it work well for everyone?
We probably don't even need a minor mode. A function might suffice: (defun xref-reset-backend () (kill-local-variable 'xref-find-function) (kill-local-variable 'xref-identifier-completion-table-function)) (defun elisp-maybe-reset-xref () (when (and buffer-file-name (string-prefix-p source-directory buffer-file-name)) (xref-reset-backend))) (add-hook 'emacs-lisp-mode-hook 'elisp-maybe-reset-xref)But please, someone else should make the choice: I rarely ever use tag files, and never with Emacs Lisp.
