I discovered recently that sometimes the buffer stops following the last lines. If I want to see the last appended lines in this buffer, I need to go in the buffer and jump to the end manually, with M->. Which is quite annoying and disruptive. I am trying to reproduce the "tail -f" command line, in a buffer. Of course 'auto-revert-tail-mode complains that the *Messages* is not a visited file... As a consequence, this mode does not want to work. But it gave me the idea to add a function hook when the buffer is modified. That function would jump to (point-max) each time that buffer is modified. Here is my own attempt, invoked from *Messages* buffer, with M-: (add-hook 'after-change-functions (lambda (s e l) (goto-char (point-max))) nil t) But it does not work. The (point) remains in the same place while I see the buffer is growing... The lambda function does not produce any error, otherwise it would have been removed from the 'after-change-functions hook and C-h k 'after-change-functions shows it is present. Any better suggestions?
