How to expand/collapse a diff sections in Vimdiff?
提问by TCSGrad
I've started using vimdiff today, and wanted to do some of the things that I've taken for granted on Windows based diff editors (like expand/collapse a diff section, have full file expansion/only diffs with 3 context lines above or below, etc.). I currently know only the following commands :
我今天开始使用 vimdiff，并且想做一些我在基于 Windows 的差异编辑器上认为理所当然的事情（例如展开/折叠差异部分，具有完整的文件扩展/仅具有 3 个以上上下文行的差异或下面等等）。我目前只知道以下命令：
Keyboard Shortcuts:
键盘快捷键：
do- Get changes from other window into the current window.
dp- Put the changes from current window into the other window.
]c- Jump to the next change.
[c- Jump to the previous change.
CTRL+W, w- Switch to the other split window (CTRL+W, CTRL+Wdoes the same thing, in case you let go of the CTRLkey a bit later)
do- 从其他窗口获取更改到当前窗口。
dp- 将当前窗口的更改放入另一个窗口。
]c- 跳转到下一个更改。
[c- 跳转到上一个更改。
CTRL+ W, w- 切换到另一个拆分窗口（CTRL+ W, CTRL+W做同样的事情，以防你CTRL稍后松开键）
Could someone point me to the right direction so I could replicate similar features?
有人可以指出我正确的方向，以便我可以复制类似的功能吗？
It would be nice if I could expand/collapse lines around the diffs, for example.
例如，如果我可以在差异周围展开/折叠线，那就太好了。

Aside from the ones you mention, I only use frequently when diffing the following:
除了你提到的那些，我只在区分以下内容时经常使用：
:diffupdate:diffu-> recalculate the diff, useful when after making several changes vim's isn't showing minimal changes anymore. Note that it only works if the files have been modified inside vimdiff. Otherwise, use::eto reload the files if they have been modified outside of vimdiff.
:set noscrollbind-> temporarily disable simultaneous scrolling on both buffers, reenable by:set scrollbindand scrolling.
:diffupdate:diffu-> 重新计算差异，在进行多次更改后，vim 不再显示最小更改时很有用。请注意，只有在 vimdiff 中修改了文件时，它才有效。否则，请使用：:e如果在 vimdiff 之外修改了文件，则重新加载文件。
:set noscrollbind-> 暂时禁用两个缓冲区上的同时滚动，重新启用:set scrollbind和滚动。
Most of what you asked for is folding: vim user manual's chapter on folding. Outside of diffs I sometime use:
您要求的大部分内容是折叠：vim 用户手册关于折叠的章节。在差异之外，我有时会使用：
zo-> open fold.zc-> close fold.
zo-> 打开折叠。zc-> 关闭折叠。
But you'll probably be better served by:
但您可能会得到更好的服务：
zr-> reducing folding level.zm-> one more folding level, please.
zr-> 减少折叠级别。zm-> 请再折叠一层。
or even:
甚至：
zR-> Reduce completely the folding, I said!.zM-> fold Most!.
zR-> 完全减少折叠，我说！。zM-> 折叠最！。
The other thing you asked for, use n lines of folding, can be found at the vim reference manual section on options, via the section on diff:
您要求的另一件事，使用 n 行折叠，可以在vim 参考手册的 options 部分找到，通过diff 部分：
set diffopt=<TAB>, then update or addcontext:n.
set diffopt=<TAB>，然后更新或添加context:n。
You should also take a look at the user manual section on diff.

Actually if you do Ctrl+W W, you won't need to add that extra Ctrl. Does the same thing.
实际上，如果您这样做Ctrl+W W，则无需添加额外的Ctrl. 做同样的事情。

我发现令人讨厌的是，一个文件的 MySQL 关键字是小写的，而另一个大写的则显示几乎所有其他行的差异

ctrl + w, w as mentioned can be used for navigating from pane to pane.
前面提到的 ctrl + w, w 可用于在窗格之间导航。
Now you can select a particular change alone and paste it to the other pane as follows.Here I am giving an eg as if I wanted to change my piece of code from pane 1 to pane 2 and currently my cursor is in pane1
现在您可以单独选择一个特定的更改并将其粘贴到另一个窗格中，如下所示。在这里我给出一个例子，好像我想将我的一段代码从窗格 1 更改为窗格 2，目前我的光标在窗格 1 中
Use Shift-v to highlight a line and use up or down keys to select the piece of code you require and continue from step 3 written below to paste your changes in the other pane.
Use visual mode and then change it
1 click 'v' this will take you to visual mode 2 use up or down key to select your required code 3 click on ,Esc' escape key 4 Now use 'yy' to copy or 'dd' to cut the change 5 do 'ctrl + w, w' to navigate to pane2 6 click 'p' to paste your change where you require
使用 Shift-v 突出显示一行并使用向上或向下键选择您需要的代码段，然后从下面编写的第 3 步继续将您的更改粘贴到另一个窗格中。
使用视觉模式，然后改变它
1 单击“v”这将带您进入可视模式 2 使用向上或向下键选择您需要的代码 3 单击 ,Esc' 转义键 4 现在使用 'yy' 复制或 'dd' 剪切更改 5 执行 ' ctrl + w, w' 导航到 pane2 6 单击“p”将更改粘贴到您需要的位置
