paragraph fill and arguments

paragraph fill and arguments

[ypitrey]

Hi everyone,

I a m trying to make my own fill paragraph command, which i want to be an
equivalent of :

'M-x mark-paragraph'
and then
'M-x fill-region-as-paragraph'

I tried to write a function to do that :

      (defun justify ()
	 (interactive)
	 (mark-paragraph)
	 (fill-region-as-paragraphl)
	 )

The M-x twice trick works perfectly, but when I try to do 'M-x justify', I
hav an error message saying :

"justify : Wrong number of arguments: #[nil "ÀÁ!ˆÂÃĉ#ˆÅÁ!‡"
[forward-paragraph 1 push-mark nil t backward-paragraph] 4 1287337 nil], 1"

Does anyone have an idea on what it comes from?

Thanks a lot!

Yohann.

... an "l"?  I you intend to write `fill-region-as-paragraph' here
you should provide FROM and TO arguments.

yes, of course, it's a typing mistake...

thanks for your reply.

These are equivalent to

    (command-execute 'mark-paragraph)
and
    (command-execute 'fill-region-as-paragraph)


The `command-execute' function uses the `interactive' form inside the
command to build a list of arguments and then calls the function with
those arguments.

Here on the other hand, you directly call those commands as function, so if
you want to use this form, you need to pass them arguments "manually".

Try

(defun justify ()
   (interactive)
   (mark-paragraph)
   (fill-region-as-paragraph (point) (mark)))

Thanks for your answers, but i'm sorry, none of them seems to work.

first, I tried to write :

(defun justify ()
	(command-execute 'mark-paragraph)
	(command-execute 'fill-region-as-paragraph)
)

second, as it didn't work (same error message), i tried this one :

(defun justify ()
   (interactive)
   (mark-paragraph)
   (fill-region-as-paragraph (point) (mark))
)

and no more did it work.

any idea? i admit i am completely lost!

This is off-topic on emacs-devel.  Please use <help-gnu-emacs@gnu.org>
instead.

> (defun justify ()

>   (fill-region-as-paragraph (point) (mark)))
    (fill-region-as-paragraph (region-beginning) (region-end)))

... which should also get you the correct answer within one hour or less.

It seems to come from `mark-paragraph' and says that it was given 1
argument but expected a different number of arguments (zero). This
makes no sense. Please paste *exactly* the code that you tested. Have
you tried "emacs -q -no-site-file"?
