如何连接添加分隔符的行? [英] How to join lines adding a separator?

问题描述

命令J连接行.
命令gJ连接删除空格的行

The command J joins lines.
The command gJ joins lines removing spaces

是否还有一个命令来连接线，在线之间添加分隔符?

Is there also a command to Join lines adding a separator between the lines?

示例:

输入:

text
other text
more text
text

我想做什么:
-选择这4行
-如果开始时有空格和/或EOL，请删除它们
-连接线之间添加分隔符'//'

What I want to do:
- select these 4 lines
- if there are spaces at start and/or EOL remove them
- join lines adding a separator '//' between them

输出:

text//other text//more text//text

推荐答案

您可以为此使用:substitute，并在\n上进行匹配:

You can use :substitute for that, matching on \n:

:%s#\s*\n\s*#//#g

但是，这也会在末尾追加分隔符(因为该范围的最后一行也有换行符).您可以手动删除该标记，或者指定c标志并在最后一个标记之前退出替换，或者将范围缩小一个，而将:join缩小到最后一个标记:

However, this appends the separator at the end, too (because the last line in the range also has a newline). You could remove that manually, or specify the c flag and quit the substitution before the last one, or reduce the range by one and :join the last one instead:

:1,$-1s#\s*\n\s*#//#g|join
