使用 Vim 的持久撤消功能？

Vim 7.3 中的新功能之一是“持久撤消”，它允许在退出缓冲区时将撤消树保存到文件中。

不幸的是，我还没有完全能够正确启用它，或者我一定是错误地使用了它。这是我到目前为止所尝试的：

我将以下内容添加到 ~/.vimrc

set undofile                " Save undos after file closes
set undodir=$HOME/.vim/undo " where to save undo histories
set undolevels=1000         " How many undos
set undoreload=10000        " number of lines to save for undo

之后，我应该能够打开任何文件，编辑它，然后保存关闭它，当我再次打开它时，我应该能够撤消/重做，就好像我从未离开过一样。不幸的是，情况似乎并非如此，因为没有写入任何撤消文件。

注意：

我在 Win 7 上使用来自 Vim without Cream 项目的 Vim 7.3。持久撤消已内置。
$HOME/.vim/undo 存在于我的文件系统上

One of the new features in Vim 7.3 is 'persistent undo', which allows for the undotree to be saved to a file when exiting a buffer.

Unfortunately, I haven't quite been able to get it properly enabled, or I must be using it wrong. Here's what I've tried so far:

I added the following to ~/.vimrc

set undofile                " Save undos after file closes
set undodir=$HOME/.vim/undo " where to save undo histories
set undolevels=1000         " How many undos
set undoreload=10000        " number of lines to save for undo

After this, I supposedly should be able to open any file, edit it, then save-close it, and when I open it again I should be able to undo/redo as if I'd never left. Unfortunately, this doesn't seem to be the case, as no undofile is ever written.

Notes:

I'm on Win 7 using Vim 7.3 from the Vim without cream project. Persistent undo is baked-in.
$HOME/.vim/undo exists on my file system

将其放入 .vimrc 中以创建一个 undodir（如果它不存在）并启用持久撤消。在 Windows 和 Linux 上进行了测试。

" Put plugins and dictionaries in this dir (also on Windows)
let vimDir = '$HOME/.vim'

if stridx(&runtimepath, expand(vimDir)) == -1
  " vimDir is not on runtimepath, add it
  let &runtimepath.=','.vimDir
endif

" Keep undo history across sessions by storing it in a file
if has('persistent_undo')
    let myUndoDir = expand(vimDir . '/undodir')
    " Create dirs
    call system('mkdir ' . vimDir)
    call system('mkdir ' . myUndoDir)
    let &undodir = myUndoDir
    set undofile
endif

Put this in your .vimrc to create an undodir if it doesn't exist and enable persistent undo. Tested on both Windows and Linux.

" Put plugins and dictionaries in this dir (also on Windows)
let vimDir = '$HOME/.vim'

if stridx(&runtimepath, expand(vimDir)) == -1
  " vimDir is not on runtimepath, add it
  let &runtimepath.=','.vimDir
endif

" Keep undo history across sessions by storing it in a file
if has('persistent_undo')
    let myUndoDir = expand(vimDir . '/undodir')
    " Create dirs
    call system('mkdir ' . vimDir)
    call system('mkdir ' . myUndoDir)
    let &undodir = myUndoDir
    set undofile
endif

我在我的 _gvimrc 中尝试了这个：

" Persistent undo
try 
    set undodir=C:\vim\undodir
    set undofile
catch
endtry

当我删除 try-catch 括号时，它开始按照广告工作，因此：

" Persistent undo
set undodir=C:\vim\undodir
set undofile

我必须创建该目录。

I tried this in my _gvimrc:

" Persistent undo
try 
    set undodir=C:\vim\undodir
    set undofile
catch
endtry

It started working as advertised when I deleted the try-catch bracket, thus:

" Persistent undo
set undodir=C:\vim\undodir
set undofile

I had to create the directory.

我想 $HOME 并不像宣传的那样工作。

在我的系统上， :echo $HOME 显示 H:\，但 : e $HOME/ 表示：~/ 文件名无效。

你可以尝试用绝对路径看看是否能解决这个问题

现在可以按预期工作： file.txt 在 Windows 7 上的 Vim 7.4 缓冲区中打开， :setlocal undofile，然后保存对缓冲区的更改，以及撤消文件 .file.txt.un~ 会同时创建，因为 :set undodir? 报告“undodir=”。默认情况下 - 即无需手动指定。您还可以在模型行中 :set undofile 。
