[英]What is the purpose of the ‘:list’ and ‘:print’ commands in Vim?
Not looking for the help file, more for the motivation why would one use these commands?不寻找帮助文件,更多的是寻找为什么要使用这些命令的动机?
I don't recall ever using :list
in over a dozen years of Vim use.我不记得在Vim使用的十几年中使用过
:list
。
:print
I use often in this form: :print
我经常以这种形式使用:
:g/re/p
Where re
is a regular expression.其中
re
是一个正则表达式。 Handy for seeing where a string appears in a file without having to move through it.方便查看字符串在文件中出现的位置,而无需遍历它。
:list
looks neat, though. :list
看起来很整洁。 Perhaps I should :s/p/l/
in the previous command.也许我应该在前面的命令中使用
:s/p/l/
。 :-) :-)
I use :print
occasionally when I want to print only a chunk of code.当我只想打印一段代码时,我偶尔会使用
:print
。 If you have a block of text being visually selected, the command will operate only on what is selected.如果您在视觉上选择了一块文本,则该命令将仅对所选内容进行操作。
The :list
command does the same thing, but makes an effort to output things like control characters in a more readable fashion. :list
命令做同样的事情,但努力使 output 以更易读的方式控制字符。
I think those are simply old Ex commands, originating from the original vi.我认为这些只是旧的 Ex 命令,源自原始的 vi。 It's useful if you use Ex mode often (see
:help Ex-mode
).如果您经常使用 Ex 模式,这很有用(请参阅
:help Ex-mode
)。 But I use them very seldom.但我很少使用它们。
