Hello list,
I want to insert some text from a database into a buffer. This should
happen with `fill-paraph' applied, and the string contains multiple
paragraphs. I came up with this (`descr' is the string):
(let ((beg (point)))
(insert descr)
(set-mark beg)
(fill-paragraph nil t)
(set-mark nil))
This works, but I'm not feeling confident with it. The documentation of
`set-mark' says this:
...Novice Emacs Lisp programmers often try to use the mark for the
wrong purposes. ...
So.. I'm a novice elisp programmer. Is this a "wrong purpose"? What is
the idiomatic way to achieve this?
Thanks and regards
Eike

Use `narrow-to-region' to operate on the text between two positions.

Thanks for your answer! I just found out, that I completely missed the
`fill-region' function… I read the doc-string of `fill-paragraph'
multiple times and yet, I managed to ignore it.
It turns out that (fill-region start end) is what I want.
I'm sorry for the noise and confusion.
Regards
Eike
