As Greg already stated, you only need to calculate spaces if the content will be changing (i.e., date or other field(s)). Otherwise just write what you want statically in signature file as mentioned. > I do not want to do ASCII art, I am only searching a simple way to do > something close to the debian-annouce emails. > > ------------------------------------------------------------------------ > The Debian Project https://www.debian.org/ > Updated Debian 11: 11.6 released pr...@debian.org > December 17th, 2022 https://www.debian.org/News/2022/20221217 > ------------------------------------------------------------------------ > > How this header is generated? > > So do someone knows: > > 1- a simple way to draw a line (without pressing 72 times on "-") > ----------------------------------------------------------------------- Since you mentioned Emacs (in OP). One answer has been posted already about how to do so interactively. Here is how to do so with ELisp: #+begin_src emacs-lisp (insert-char ?- 72) #+end_src > 2- a simple way to align some text to the right (that is to say to > automatically calculate how many spaces are needed to fill the gap > between the text on the left an the text on the right for 72 characters > line. #+begin_src emacs-lisp (defun my-insert-line-justified (left-text right-text) "Insert justified line. Spaces between LEFT-TEXT and RIGHT-TEXT will be calculated automatically, based on 72 character overall width." (let* ((left-chars (length left-text)) (right-chars (length right-text)) (spaces-count (- 72 left-chars right-chars)) (spaces-string (make-string spaces-count ? ))) (insert left-text spaces-string right-text))) #+end_src > 3- a simple way to do boxes (no present in debian-annouce header) If you put together both things I provided above (perhaps along with some '|' characters), you should be able to figure this out for yourself. As others have pointed out, consider doing so tastefully/sparingly. -- Cheers, TRS-80
