Re: Just a thought about comment-line

[PEDRO ANDRES ARANDA GUTIERREZ]

And BTW, my code looks like:

(defun my-comment-line-region (beg end)
  "Comment all complete lines in a region using comment-line
if the region does not start at a beginning of line, expand it"
  (interactive "r")
  (save-excursion
   (save-restriction
   (narrow-to-region (get-bol beg) end)
   (push-mark (point-min))
   (goto-char (point-max))
   (call-interactively 'comment-line)
   (pop-mark))))

It seems that narrowing helps avoiding that last comment. Don't know how much of an overkill this might be, but

it works for me(tm)

Hey,

thanks for all the answers so far. It's nice to see people getting passionate about this.

I too had my code to deal with (bol-p end-of-region) and I'm passing it on to people,

but I started writing a short introduction for students who get interested in Emacs by

seeing how I use it and well, it'd be so much better for Emacs if I could get one of the

FAQ answered by something like 'customise variable so-and-so to get your desired

behaviour' instead of 'include <listing 100> in your .emacs.d/functions.el and bind function

sensible-comment-lines to M-;'

I hope the discussion crystallises in some better future :-)

Best, /PA

I wasn't complaining about `comment-dwim'.
I was saying that it's not the be-all and
end-all.  I use it for end-of-line comments.
And I use something else for block commenting.

It doesn't matter to me if you use `M-;' for
everything.  If you're happy that way, great.

I see.  If someone says your one-size-fits-all
dream command doesn't fit all then their idea
for doing something additional or different
just wastes your time.  Sorry to hear that.

Surprise!  And irrelevant.

I think I did.  Maybe you can show us how
`comment-dwim' provides the same behavior.

A bit of a tautology.  I can leap over buildings
in a single bound, in the cases where that's
really needed, which is when the buildings are
at most 1-foot tall.

Anyway.  The point of this thread is the problem
with `comment-line' raised by the OP.  If you're
curious why `comment-line' was added, since we
already had `comment-dwim', see the thread I
pointed to, where `comment-line' was discussed
and added.
