I've read the threads in this list pertaining to indentation, but I
haven't found a solution to the following problem: While editing a lisp
program, I want to keep the indentation "correct" at all times.
i.e. If I yank I want to reindent. If I delete a ), I want it to
reindent, If I insert a (, change the name of a function from if to
when, undo etc. etc. etc., I want to reindent.
The solution I came up with is:
(setq lisp-indent-function 'common-lisp-indent-function)
(add-hook 'after-change-functions
(lambda (start end pre-change-length)
(indent-region start (buffer-size) nil)))
The problem is that it somehow gets into an endless loop *sometimes*
when I undo. It might have problems in other situations, but that's
whet I've found so far.
Sorry, I can't help you with that. But I can tell you that (buffer-size)
should almost certainly be (point-max). And you might want to add a check
for (eq major-mode 'lisp-mode), or make after-change-functions a local hook
variable in Lisp mode buffers (by putting the add-hook in a lisp-mode-hook
function, and specifying the optional LOCAL arg).
You might also have better luck if you call indent-region with a region
that starts at the beginning of the line:
(save-excursion (goto-char start) (line-beginning-position))
