vim - Editing read-only file on GVim

Question

Is there any way to edit read-only file on GVim?

If you use vim on console, sudo vim /path/to/file enables you to edit the read-only file. How can I edit it on already-opened MacVim window?

If you open :tabnew /path/to/file then edit it, and try to save it, then the error occurs saying xx is read-only (add ! to override). However, when you try to save it by :w!, the error still occurs saying xx Can't open file for reading.

I know, if you first change the permission of the file and edit it, and then reverts its permission, then you can edit it successfully... But I don't want to bother doing such a tedious thing...

Thanks.

Answer 1

MacVim 带有mvim一个命令行包装器，它允许您从命令行启动 MacVim GUI，$ mvim filename并在您的 shell 中直接启动 MacVim CLI 可执行文件$ mvim -v filename。

两者都可以很好地工作，sudo因此您可以完美地在新的 MacVim 窗口中以写入权限$ sudo mvim filename打开，或者在当前的 MacVim 窗口中执行相同的操作。filename$ sudo mvim --remote filename

更改权限/所有者：

:!chown myuser %
:!chmod +w %

sudo或使用管道编写：

:w !sudo tee %

如果你发现这个技巧tee太难记/太难输入，还有SudoEdit 插件，它定义了一个方便的:SudoWrite命令。
