[英]How to add a line after every few lines in vim
I wanted to add a line after every 3 lines in a file (having about 1000 lines) using vim editor. 我想使用vim编辑器在文件中每隔3行添加一行(大约1000行)。 Can someone help me out?
有人可以帮我吗?
Thanks, Alisha 谢谢,艾丽莎
there is a vim-specific regular expression to do that 有一个vim特定的正则表达式来做到这一点
:%s/.*\n.*\n.*\n/\0\r/g
Edit: if you want anything else than a new line, just put the text in front of the \\r (properly regex escaped, if it contains some regex characters) 编辑:如果你想要一个新行,只需将文本放在\\ r \\ n之前(正确的正则表达式转义,如果它包含一些正则表达式字符)
You can use a macro . 你可以使用宏 。 The complete process looks like:
完整的过程如下:
qq " start recording to register q (you could use any register from a to z)
o " insert an empty line below cursor
<Esc> " switch to normal mode
jjj " move the cursor 3 lines downward
q " stop recording
Then just move to the start line and type 1000@q
to execute your macro 1000 times. 然后只需移动到起始行并输入
1000@q
即可执行1000次宏。
" insert a blank line every 3 lines
:%s/\v(.*\n){3}/&\r
: .............. command
% .............. whole file
s .............. replace
/ .............. start pattern that we will replace
\v ............. very magic mode, see :h very-magic
(.*\n) ......... everything including the line break
{3} ............ quantifier
/ .............. start new pattern to replace
& .............. corresponds to the pattern sought in (.*\n)
\r ............. add line break

I would do this: 我会这样做:
:%s/^/\=(line(".")%4==0?"\n":"")/g
this works if your requirement changed to " * add a new blank line every 700 line *s" :) you just change the "4" 如果您的要求更改为“* 每700行 * s 添加一个新的空白行 ”,则此功能可用 :)您只需更改“4”
PS if I need do this, I won't do it in vim. PS如果我需要这样做,我不会在vim中这样做。 sed, awk, could do it much simpler.
sed,awk,可以做得更简单。
