在记事本中将内容中的多个空行折叠为一行

Question

Is there a way in Notepad++ to collapse multiple empty lines in content to a single line?

For example, from this:

Line0
Line1


Line2



Line3

Line4
Line5

to this:

Line0
Line1

Line2

Line3

Line4
Line5

I would like to run a replacement on a folder with "Find In Files" function; is there a way to be able to do it?

Answer 1

[\r\n]{2,}

You can replace by \\n or \\n\\n .See demo.

use (?:\\r\\n){2,} for notepadd ++
