Vim：如何滚动光标线呢？

Question

Two windows in a split windows view of Vim can be bound to each other for scrolling by setting :set scrollbind for both of them. After this is done, if I scroll down the cursor in one windows, the other windows scrolls down along with it.

But, the cursors in the two windows are not bound to each other. I have used :set cursorline to highlight the current line on which the cursor is present. How do I make the highlighted cursorline to scroll simultaneously in the other window too?

Answer 1

I don't use this myself, and I may be missing the point, but

:set cursorbind

seems to do exactly what you want.

Answer 2

I just encountered the same situation (with only two windows to compare), and what I did was:

:set cursorbind
:set scrollbind
:set cursorline

and then

:map <Down> j<C-w><C-w><C-w><C-w>
:map <Up> k<C-w><C-w><C-w><C-w>

This causes every press on the up or down arrows to switch back and forth between the windows once, which updates the cursor position on the other window (You can :redraw!<CR> instead of the ugly window switching but that looks bad when moving too fast). Of course, there are many ways to move between lines without the arrows, so this is far from perfect.

However, since this is not a main mode of work for me, useful primarily for comparing files on which diff is too complicated to look at for whatever reason, I find this setting to be practically good enough.

Answer 3

I came up with this solution when I wanted to do a "cross-window column tracking" in a vimdiff session (in additional to "cross-window row tracking"). Probably this would solve your problem as well.

First enable cursorcolumn , cursorbind , cursorline and scrollbind on each window.

:windo set cursorcolumn | set cursorbind | set cursorline | set scrollbind

Then map the hjkl motion keys to update the cursor position for each movement.

:nmap h h:let curwin=winnr()<CR>:keepjumps windo redraw<CR>:execute curwin . "wincmd w"<CR>
:nnoremap j j:let curwin=winnr()<CR>:keepjumps windo redraw<CR>j:execute curwin . "wincmd w"<CR>
:nmap k k:let curwin=winnr()<CR>:keepjumps windo redraw<CR>:execute curwin . "wincmd w"<CR>
:nmap l l:let curwin=winnr()<CR>:keepjumps windo redraw<CR>:execute curwin . "wincmd w"<CR>

Answer 4

I found this page in the vim documentation thought you might find it helpful: http://vimdoc.sourceforge.net/htmldoc/scroll.html#scroll-binding

Sometimes I find that straight from the horses mouth is the best.

Answer 5

I made a tiny change to cychoi 's answer . Remap h,j,k,l in the diff mode and remove a 'j' hit in cychoi 's original mapping:

if &diff
  au VimEnter * windo set cursorcolumn | set cursorbind | set cursorline | set scrollbind
  nmap h h:let curwin=winnr()<CR>:keepjumps windo redraw<CR>:execute curwin . "wincmd w"<CR>
  nmap j j:let curwin=winnr()<CR>:keepjumps windo redraw<CR>:execute curwin . "wincmd w"<CR>
  nmap k k:let curwin=winnr()<CR>:keepjumps windo redraw<CR>:execute curwin . "wincmd w"<CR>
  nmap l l:let curwin=winnr()<CR>:keepjumps windo redraw<CR>:execute curwin . "wincmd w"<CR>
endif

I think this setting is good for CSV line-by-line diff.
