在Vim命令行中增加一个数字
在普通模式下(在Vim中),如果光标在数字上,按Ctrl-A会将数字增加1.现在我想做同样的事情,但是从命令行。 具体来说,我想去某些行的第一个字符是数字,并增加它,即我想运行以下命令:
:g/searchString/ Ctrl-A
我尝试将Ctrl-A存储在一个宏(比如a
)中,并使用:g/searchString/ @a
,但出现错误:
E492:不是编辑器命令^ A
有什么建议么?
您必须使用normal
来在命令模式下执行正常模式命令:
:g/searchString/ normal ^A
请注意,您必须按Ctrl-VCtrl-A才能获得^A
字符。
除了CMS发布的:g//normal
技巧外,如果您需要使用更复杂的搜索来完成此操作,而不是在行首找到一个数字,则可以执行如下操作:
:%s/^prefix patternzsd+zepostfix pattern/=(submatch(0)+1)
作为解释:
:%s/X/Y " Replace X with Y on all lines in a file
" Where X is a regexp:
^ " Start of line (optional)
prefix pattern " Exactly what it says: find this before the number
zs " Make the match start here
d+ " One or more digits
ze " Make the match end here
postfix pattern " Something to check for after the number (optional)
" Y is:
= " Make the output the result of the following expression
(
submatch(0) " The complete match (which, because of zs and ze, is whatever was matched by d+)
+ 1 " Add one to the existing number
)
我相信你可以在命令行上用vim来做到这一点。 但是这里有一个替代方案,
$ cat file
one
2two
three
$ awk '/two/{x=substr($0,1,1);x++;$0=x substr($0,2)}1' file #search for "two" and increment
one
3two
three
