execute after char/string

execute after char/string

[Steve Chow]

is there a way I can execute a function/macro after I've inserted a
character or string? In this case I'd like execute a function after
typing . or -> in c-mode. I tried using global-set-key but then of
course it won't let me enter those characters into the buffer.

See after-change-functions.

A spicedup self-insert-command is much simpler I think.

(defun super-dot-minus-arrow (&optional arg)
   (interactive "p")
   (self-insert-command arg)
   (do-some-more-stuff-when-apropriate))

(define-key your-map (kbd ".") 'super-dot-minus-arrow)

-ap

this will work:

(defun ff ()
  "type period then do y."
  (interactive)
  (let ()
    (self-insert-command 1)
    (funcall 'y)
    )
  )

(global-set-key (kbd ".") 'ff)


the y is whatever your function.

 for "->", you could do the above for “>”, and the ff checks whether
previous char is “-”.

I don't have anything to do after inserting the character, but before.

It goes something like this:

(defun fix-array-index(&optional arg)
  (interactive "p")
  ;; go fix up the index value, if needed
  (self-insert-command arg))

And the following in the mode hook:
    (local-set-key "]" 'fix-array-index)

with some checks to do it only once.
