line-move-visual?

[Leo]

Hi there,

It looks the change that C-n and C-p now move by screen lines are pretty
big. Any idea why this has been set as default? What's the user case for
this?

Thank you so much.

Best,

Do you mean to say that in the dev version of emacs, now up/down arrow
key moves the cursor by a screen line instead of moving by EOL char?

Hurray! One critical emacs modernization down, few more to go!

-----------------

as answer to your question, moving by screen line is more natural, and
is the behavior by all modern software. I don't know if this is how
emacs developers felt when the change is made, but probably similar.

the moving by screen line is a frequently requested feature, poping up
every couple of months in gnu.emacs.help or comp.emacs.

------------------

btw, what's the behavior of kill-line? Does it do screen line or EOL
line?

Yes.

The documentation of `next-line' function now says:

    If the variable `line-move-visual' is non-nil, this command moves
    by display lines.  Otherwise, it moves by buffer lines, without
    taking variable-width characters or continued lines into account.

It kills ``buffer lines''.  To kill a single display line one can move
the point to the start of that line with the arrows, select the display
line with `S-<down>' or `C-SPC S-C-n' and kill the display line with
`C-w' as usual.

It kills till EOL.

To make kill-line kill till the end of the screen line, you have to
enable visual-line-mode, which indeed changes line-wrapping, too.  (It
does wrapping only on word boundaries and not inside words.)
