Merge the current line with the line above in Vim

Question

I have a pretty long list, like so:

itemOne
itemTwo
,itemThree
itemFour
itemFive
,itemSix
,itemSeven

Each line that starts with a comma needs to be merged with the line above, like so:

itemOne
itemTwo,itemThree
itemFour
itemFive,itemSix,itemSeven

How can I do this?

Answer 1

一种有效的方法是使用以下:global命令：

:g/^,/-j!

Answer 2

你可以这样做：

:%s/\n,/,/g

Answer 3

Try this substitution:

:%s#\n\ze,##

Explanation:

• %s# begin a substitution on all lines.
• \\n match the newline character.
• \\ze, set the end of the match before the comma so the comma will not be replaced.
• ## replace with nothing (to remove the newline character).
