macro with argument

macro with argument

[Joerg Schuster]

Hello,

how can I write "macros with arguments"?

Example: 

[Me:]    M-x my_macro
[Emacs:] your argument:
[Me:]    foo

Then emacs should print e.g.

bla foo blo

(defun my_macro (string) (interactive "syour argument: ") (message
"bla %s blo" string))

I.e. - write a small e-lisp function to achieve what you want, and not
a conventional macro. Check the documentation of the special form
(interactive )
 
               C-h f interactive

too see how the argument is read from you.

This prints "bla [argument] blo" in the mini buffer. I wanted Emacs to
print it in the active (?) buffer, i.e. in the buffer from which I
call the function.

Replace the (message ) function with (insert ):

  (insert (format "bla %s blo" string))
