Ⅳ. 文档说明

If you want 'undofile' only for certain files, you will notice that 'undofile' cannot be set in a modeline, or once the buffer is loaded (because an existing undo file will not be loaded then).  Bram suggests to use a BufReadPre autocmd which sets 'undofile' before the buffer is loaded.  This script does the steps for you.

Usage:

:SetUndoFile[!]

  execute :setlocal undofile, install a BufReadPre autocmd for the current file name and also maintain a plugin file "plugin/undofile_autocmds.vim" that enables all such autocmds at next startup of Vim.

  This means you can execute this command once for the current file and then never ever again -- FIRE AND FORGET ;)

  The plugin file (if not found in the runtimepath) is stored in the first directory of the runtimepath (which must contain a "plugin" folder).  Older Vims will ignore the plugin.

  With [!], ignore if 'undofile' is already set.

:UnsetUndoFile

  opposite of :SetUndoFile.  Does :setlocal noundofile, removes the autcommand and the autcommand entry from "plugin/undofile_autocmds.vim"; finally it executes :DelUndoFile.

:DelUndoFile

  delete the undofile for the current buffer.  Fails silently.
