问题描述
vim 中的寄存器是一个很棒的功能,可以存储文本片段,甚至可以对存储在其中的文本运行命令.不过,我是个很整洁的人,做完后会收拾东西.
Registers in vim are a great feature to store text snippets and even to run commands on the text stored within them. However, I'm a tidy person and tend to clean things up when I'm done.
我知道如果我想清除寄存器 a
,我可以使用 .
I know that if I wanted to clear register a
, I can use .
我也可以执行以下命令:
I can also execute the following command:
:let @a = ''
然而,这些解决方案似乎只是解决问题的方法.当我执行 :registers
时,列表仍然显示 register a
(具有空值),而不会显示从未使用过的寄存器.
However, these solutions seem like a mere workaround to the problem. When I execute :registers
, the list still displays register a
(with an empty value), while registers that have otherwise never been used are not displayed.
有没有办法清除一个具有从该列表中删除寄存器的副作用的寄存器?
Is there a way to clear a register with the side-effect of removing the register from this list?
如果是这样,是否还有一种方法可以一次清除所有寄存器,即重置该寄存器列表?
And if so, is there also a way to clear all registers at once, i.e., to reset that list of registers?
推荐答案
由于邮件列表中的那个古老的答案,由 @romainl 链接,我们有 setreg('a', [])
清除寄存器.
Since that venerable answer on the mailing list, linked by @romainl, we have setreg('a', [])
that clears the register.
因此,代码可以变成:
let regs=split('abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789/-"', '\zs')
for r in regs
call setreg(r, [])
endfor
