wait/sleep in a keyboard macro?

wait/sleep in a keyboard macro?

[kent williams]

Prior to emacs 23, I had a simple keyboard macro I used to log in to a
chat server via telnet.  Yes, the password was plain text in the macro
body in my .emacs, but this was not a high-security thing.

But this dumb macro stopped working in emacs 23.  The reason being --
well the behavior differs now based on whether the buffer for the
telnet session already exists, but most commonly, I get an error
message "Marker does not point anywhere".

The macro itself is this:


(fset 'hardcorps
   [?\M-x ?t ?e ?l ?n ?e ?t ?\C-m ?c ?h ?a ?t ?. ?f ?4 ?. ?c ?a ?  ?6
?6 ?2 ?3 ?\C-m ?* ?* ?* ?* ?\C-m ?* ?* ?* ?* ?* ?* ?* ?* ?* ?*
?\C-m])

in other words: alt-X 'telnet chat.f4.ca 6623' <return> '<login name>'
<return> '<password>' return

It appears (to me) that what happens is that the macro runs too fast,
such that when it tries to add the login name to the buffer, the
buffer isn't yet connected to the server, or it isn't ready for input.
Or something!

I suppose it's possible to do this in a more sophisticated way in
lisp, but this hasn't risen to the level of importance for me that I'm
ready to puzzle out how to wait for prompts from a remote host before
adding text to the buffer.

How about advising the telnet function to wait a bit after it runs if a
keyboard macro is executing?

(defadvice telnet (after pause-during-keyboard-macro activate)
  (when executing-kbd-macro
    (sleep-for 1)))

Season the sleep-for delay to taste.
    
Not very sophisticated, but it gets the job done.

Try M-: (sleep-for 1) RET
