vim / NERDtree / Folding - 它能记住折叠的状态吗？
有没有办法让 NERDtree 在从一个缓冲区切换到另一个缓冲区时记住折叠的状态？
这是我完整的 .vimrc：
set ignorecase
set scs
let perl_fold=1
hi Folded cterm=bold ctermfg=yellow ctermbg=lightblue
set modeline
cabbr N NERDTree
这是我所观察到的：
- 启动 NERDTree
- 选择一个文件并使用空格键在新缓冲区中打开它（所有折叠都关闭）
- 在缓冲区中打开一些折叠
- C-w w 返回 NERDTree
- 选择另一个文件，使用空格键打开它
- C-w w 回到 NERDTree
- 选择第一个文件，按空格键
我原来打开的折叠现在关闭了。 我正在编辑 perl 文件，因此 perl_fold=1 有效。 我希望当我从一个文件跳到另一个文件时能够记住折叠的状态。
Is there a way to make NERDtree remember the state of folds when switching from buffer to buffer?
Here the my complete .vimrc:
set ignorecase
set scs
let perl_fold=1
hi Folded cterm=bold ctermfg=yellow ctermbg=lightblue
set modeline
cabbr N NERDTree
Here is what I am observing:
- start NERDTree
- select a file and use spacebar to open it in a new buffer (all folds are closed)
- open some folds in the buffer
- C-w w back to NERDTree
- select a different file, use spacebar to open it
- C-w w back to NERDTree
- select the first file, hit spacebar
The folds I had opened originally are now closed.
I am editing perl files,so the perl_fold=1 is in force.
I'd like the state of the folds to be remembered as I bounce around from file to file.

您确定
不管怎样，NERDTree 与你的缓冲区内容或状态无关，它只是一个文件浏览器。
如果没有某种机制来保持缓冲区的状态，当您打开新文件时，您的折叠就会丢失。幸运的是，您可以将
set hide添加到您的 .vimrc 中。使用它，缓冲区会保留下来，直到您使用
:bd显式删除它们为止。这意味着，通过使用 NERDTree 或使用:b返回到之前的文件时，您仍然保留折叠。Vim wiki 有 nice 有关缓冲区的页面。
Are you sure about the
<Space>mapping? I don't see it listed in NERDTree's help.Anyway, NERDTree has nothing to do with your buffers content or state, it's only a file explorer.
Without some mechanism to keep state of your buffers your folds are lost when you open a new file. Luckily you can add
set hiddento your .vimrc.With it buffers are kept around until you explicitly delete them with
:bd. This means that you still have your folds when going back to your previous file, either by using NERDTree or by using:b <Tab>.The Vim wiki has nice pages about buffers.
