DWIM when yanking strings with leading or trailing spaces - an idea

[Marcin Borkowski]

Hi folks,

take this example:

--8<---------------cut here---------------start------------->8---
Lorem ipsum -!-dolor sit amet.
--8<---------------cut here---------------end--------------->8---

As usual, -!- denotes the point (which can be here because e.g. of an
earlier C-left).

Now press C-backspace, C-right, C-y.

This is the result:

--8<---------------cut here---------------start------------->8---
Lorem doloripsum  sit amet.
--8<---------------cut here---------------end--------------->8---

Some other text processing software, whose name will not be mentioned,
does "the right thing" in such a case, i.e., produces

--8<---------------cut here---------------start------------->8---
Lorem dolor ipsum sit amet.
--8<---------------cut here---------------end--------------->8---

Why couldn't Emacs do this?  Of course, optionally.  I could spend some
time working on this issue, and e.g. submit the result to Elpa.  Would
anyone be interested?

Of course, this particular example is rather bad, since a simple M-t
would do.  But you get the idea, and quite often transposing is not
enough, e.g., when you want to transform

--8<---------------cut here---------------start------------->8---
aaa bbb ccc ddd eee fff
--8<---------------cut here---------------end--------------->8---

into

--8<---------------cut here---------------start------------->8---
aaa ddd eee bbb ccc fff
--8<---------------cut here---------------end--------------->8---

Best,

M-- M-2 M-t M-3 M-f M-- M-2 M-t

Et voilà! ;-)

OK, I can also prove that every permutation can be decomposed into
a superposition of transpositions.

By all means. ;-)

I just wanted to say (but perhaps I should actually have said it ;-)
that I personally rarely find myself wishing Emacs would insert that
extra space. I either use transpose-words couple of times, with or
without prefix arguments, or I kill the relevant word together with a
space before or after and yank it in such a way that that space is in
the right position. (I admit I get it wrong sometimes...)

What I do run into from time to time, is wanting to transpose clauses
within a sentence and having to manually adjust the punctuation and
possibly an "and" or an "or". But I suspect we'll have to plug Emacs
into Skynet first before it can be taught to autocorrect such cases.

Anyway, my opinion shouldn't stop you from creating such a package, of
course. I mean, it bugs you, so that should be enough of a reason,

right? ;-)

And in my case, the problem happens more often.  The reason is that
I work in a journal as a copyeditor/proofreader, and I move around whole
clauses quite a lot.

In one case, it's easy: I have a function which inserts a dash, killing
any other punctuation in that place, and if region is active, it
surrounds it with dashes.  /Extremely/ useful.  Also, this:

Yes and no.  It's on the limit of the "automation horizon" (see
https://xkcd.com/1205/) ;-)

Nice.

For me, though, this:

,----
| And now that I have this, I think I could do a similar thing with C-t,
| so that it transposes two chars before the point (as opposed as two
| chars around the point) if there is a space before the point.
`----

would be a bad idea, because I often use `transpose-chars' to correct
things like "th emistake". Which I unfortunately type quite often...

So you basically posted your question looking for an excuse to do some
coding? ;-)

Ah, I see.  I seldom make this kind of mistake.  Though it turned out
I didn't do that anyway.

Exactly. ;-) As Emperor Palpatine once put it, "now feel the power of
procrastination!"
