问题描述
假定当前缓冲区是一个打开供编辑的文件，则:e不显示E32: No file name.
Assuming the current buffer is a file open for edit, so :e does not display E32: No file name.
我想拉一个或全部:
- 文件名与状态行上显示的完全相同，例如
~\myfile.txt - 文件的完整路径，例如
c:\foo\bar\myfile.txt - 只是文件名，例如
myfile.txt
- The file name exactly as show on the status line, e.g.
~\myfile.txt - A full path to the file, e.g.
c:\foo\bar\myfile.txt - Just the file name, e.g.
myfile.txt

这会将文件名复制到 unmed寄存器，然后您可以使用较旧的p进行粘贴.当然，您也可以将其映射到键以便更快地使用.
this will copy the file name to the unamed register, then you can use good old p to paste it. and of course you can map this to a key for quicker use.
:nmap cp :let @" = expand("%")<cr>
您也可以将其用于完整路径
you can also use this for full path
:let @" = expand("%:p")
说明
Vim使用未命名寄存器来存储已删除或复制(被选中)的文本，同样，当您粘贴它时，它将从该寄存器中读取文本.
Vim uses the unnamed register to store text that has been deleted or copied (yanked), likewise when you paste it reads the text from this register.
使用let，我们可以使用:let @" = "text"将文本手动存储在寄存器中，但是我们也可以存储表达式的结果.
Using let we can manually store text in the register using :let @" = "text" but we can also store the result of an expression.
在上面的示例中，我们使用功能expand扩展通配符和关键字.在我们的示例中，我们使用expand('%')扩展当前文件名.我们可以将其修改为完整文件名的expand('%:p').
In the above example we use the function expand which expands wildcards and keywords. in our example we use expand('%') to expand the current file name. We can modify it as expand('%:p') for the full file name.
