point when modifying other buffers

point when modifying other buffers

[Daniel Carvalho]

hi
I want a lisp program to make changes to other buffer without visually
switching to it.

(with-current-buffer my-other-buffer
  (insert "abc\n")
  )

this keeps a temporary cursor while the elisp program runs but doesn't
move the buffer "real" position.
How can I make it change the buffer position?

(insert-before-markers "abc\n") works in this case, but it is not a
generic solution

I could use something like
(set-window-point window position)
but only if there is a window displaying the buffer!


I would like to listen for clarifications on this subjet, and if there
are better solutions

thanks
lDanie

There is no such thing as the buffer's "real" position.

But what you think as "the real position" is indeed the window-point.
If there's no window showing this buffer, you'll see that point moves
along with your text without having to do anything extra.
