git show old version of file in editor
提问by kodu
I figured out I can show old versions of a file using 'git log filename' to show the commits, and then use 'git show commit-id:filename' for the old version. But it just puts it in less.
我发现我可以使用 'git log filename' 显示文件的旧版本来显示提交，然后使用 'git show commit-id:filename' 来显示旧版本。但它只是把它放在更少的地方。
I would like to be able to view this in emacs, so I can navigate as I'm used to and so that there is syntax highlighting. I found out I can't set the git core.pager to emacs since emacs cannot read from stdin.
我希望能够在 emacs 中查看它，这样我就可以按照我习惯的方式进行导航，这样就可以突出显示语法。我发现我无法将 git core.pager 设置为 emacs，因为 emacs 无法从 stdin 读取。
Does anyone know how I could do this? Or do you have another good way of checking old versions of files?
有谁知道我怎么能做到这一点？或者你有另一种检查旧版本文件的好方法吗？

Using the following Vim command, one can view a previous version of a file without having to cleanup anything afterward.
使用以下 Vim 命令，您可以查看文件的先前版本，而无需事后清理任何内容。
git show commit-id:filename | vim - -n
Explanation: The dash argument of the vim command makes vim load whatever comes in from standard input. The -n option suppresses the creation of swap files.
说明：vim 命令的 dash 参数使 vim 加载来自标准输入的任何内容。-n 选项禁止创建交换文件。
