如何在Emacs中自动换行？

Question

如何配置emacs以便换行不会在单词中间中断？

Answer 1

If you want to emulate the behavior of an editor like Notepad, you might want to turn on visual line mode. While setting word-wrap will cause line wrapping at word boundaries, any action you take on a line (eg, moving up/down or killing) will still respect the newline character. Visual line mode will treat each display line as though it had a newline at the end.

(visual-line-mode t)

Line to add in .emacs file:

(global-visual-line-mode t)

Answer 2

Can you specify what kind of wrapping are you talking about ?

Mx toggle-truncate-lines disable allow you to disable visually line breaking.

Mx auto-fill-mode + Mq allow you to wordwrap for real a pre-existing paragraph.

Answer 3

Add this to your init file:

(setq-default word-wrap t)

Alternatively, press Ch v word-wrap in Emacs and follow the "customize" link near the end.

Answer 4

I discovered longlines-mode only recently (I think I was spelunking through the emacs Info docs). It wraps as you would expect in other UI editors' word-wrap feature. It's especially useful when I'm reading or writing free text with no newlines (a la Word) without the ugly mid-word wrapping that happens when you use Mx toggle-word-wrap .

my config:

(setq longlines-wrap-follows-window-size t)
(global-set-key [(control meta l)] 'longlines-mode)
