insert text after a char depending on next char

insert text after a char depending on next char

[Sebastian Meisel]

Hallo,

is the following possible in emacs, and if it is how can it be done:

I want emacs  to insert  "\," after a dot ("."), when no space is following:

I type: "Hallo World. Hallo World." -> emacs shall not insert anything, 
because a space is following.
I type: "Hallo World.Hallo World." -> emacs shall insert "\," after the 
dot resulting in: "Hallo World.\,Hallo World.".

Thanks for any hints.

Sebastian Meisel

Something like this:

(defun qwerty()
  (interactive)
  (cond ((looking-at " ") (insert "."))
        (t (insert ".\\,"))))

(local-set-key (kbd ".") 'qwerty)


Seems like the sort of thing you'd want to add more conditions to

At first I thought about something like that too, but you got to
realize that when he types the '.' he still has not completed the rest
of the sentence...
So it seems that the correct would be: after any keypress, look back:
if there is ". " then nothing, is there is ".H" then insert \, after
the dot...

Cheers,

Time is an illusion. Lunchtime, doubly so.

(defun qwerty()
  (interactive)
  (insert ".")
  (let ((c (read-event)))
    (cond
     ((eq 32 c) (insert " "))
     (t (insert (concat "\\," (make-string 1 c)))))))

There is one last thing I'm missing to make it perfect (which that 
solution is close to): Is there a way to handle M- and C- events so they 
are evaluated not by the function, but with there standard binding?
