supercite (sc-citation-leader " ") kill indentation, in a intelligent way

supercite (sc-citation-leader " ") kill indentation, in a intelligent way

[Uwe Brauer]

Hi

I use supercite with the following setting

(sc-citation-leader "   ")
(setq sc-nested-citation-p t)

But sometimes I want to delte  indentation of the quoted text:

So I wrote that small funktion



(defun my-delete-indentation-msg ()
"Small hack to delete indentention of quotes caused by  `sc-citation-leader'."
  (interactive)
  (save-excursion
    (mail-text)
    (indent-rigidly (point) (point-max) -50 -50)))

But of course it kills all indentation. Is there a way only to kill the
indentation of the quoted text, which has a 
      >  prefix

Or a 

     RMS> prefix

Regards

Uwe Brauer

If so, let me advise you against using it, and any idiosyncratic citation styles in general.

Only that is less than 50 chars wide, IIUC.

Why there should not be?  What youʼve just described does not feature anything ‘supercite’-specific and translates to Elisp straightforwardly.  Interpreting your ‘RMS’ as any word (in a sense of syntax tables):

	(defun oub-mail-unindent (&optional beg end)
	  (interactive (when (use-region-p)
	                 (list (region-beginning) (region-end))))
	  (setq beg (or beg (mail-text-start))
	        end (or end (point-max)))
	  (save-excursion
	    (goto-char end) (forward-line 0)
	    (while (<= beg (point))
	      (when (looking-at
	             (rx (seq (one-or-more (literal sc-citation-leader))
	                      (group (zero-or-more word) ">"))))
	        (replace-match "\\1" t))
	      (forward-line -1))))

(Not tested.)

Right it does, but this particular feature (the prefix UB) I usually
turn off, [1]

I only turn it on if I reply to several messages at once (which I use
from time to time) then it is very very useful.

Great it works like expected thanks a lot!!!

Footnotes:
[1]  the indent feature I regularly use (and so does RMS) because it
     makes the quotes more visible. Some mail readers have difficulties
     with this intention and that is why I turn it of in newsgroups and
     mailing list, and also want to have the freedom to delete if necessary in ordinary email.

You are welcome.

FWIW, until five years ago or so RMS had been using an ancient style of indent-only (no ‘>’), that is, he might be viewed as being in a prolonged transition to a conventional one.

> because it makes the quotes more visible.

Why do not you embed in your mail a CSS style, where quotes are highlighted with a favourite colour for quotes instead, I wonder? ;-)

Both approaches are equally fundamentally broken in their premise, but the latter is at least easy ignorable recipient-side.

Indeed.

Ah right I forgot about that.

Well, there are people who hate html message so I try to keep a low
profile on that. On the other hand I am curious: When I use html it is
mostly when I use either

    1. Mathematical symbols, and equations or

    2. Tables 

I generate the corresponding html mail,  with org-mime-htmlize and I am not aware that this
function has such a highlighting functionality, which leads me to the question:

Do you know about a lisp function or package which indeed implements
that?

Another problem with this approach is, that still, not all mail reader
(most likely mutt) do not fully support html mail, at least last time I
tried, which was, I admit, some time ago.

I am not sure I understand, why you consider the use case of replying to several
recipient with the same mail, as fundamentally broken?

I believe there may have been sarcasm involved, and I believe the 
point was something similar to "Using any kind of quoting marks 
that are not handled automatically by everyone's email client, is 
almost as bad as sending them html - so in the same way that you 
kindly send plain text instead of html, please also kindly use 
built-in automatic quoting marks only".

I thought that, but then I hoped he had some magic lisp code hidden
somewhere. BTW talking about idiosyncratic styles: 

Wouldn't that cover the use of *very long (more than 80 chars) lines* which
some client, such as gnus, rather prefer not to send, at least they emit
a warning. Just a thought.....
