Visual Studio Code - delete all blank lines - regex

Question

I spent some time trying to figure out how to delete all blank lines in Visual Studio Code and I can't get it working. Anybody knows how to do it please?

If I search for ^$ while typing it in search field VSC does find the blank lines (completely blank lines, means no white spaces) but it doesn't remove them when I hit Replace All. It does nothing:

For blank lines with spaces ^\s+$ Search works, but it does not remove them. What it does is it replaces them with a blank line without spaces :))

It must be I am doing something wrong. I just can't figure out what is it. Anybody knows? Thanks.

Answer 1

For those who might be interested - what worked for me in version 1.3.1 (and still works in 1.33.1) to delete blank lines I used ctrl+h (find and replace) alt+r (Use regular expression)

In find box then:

\n\n

In replace box:

\n

This should make two consecutive end of line signs into one.

If you need to replace more empty lines (more than two) at once, you can use following regular expression in find box:

\n+

If you need to replace also empty lines with whitespaces, then you need to use following regular expression in find box:

\n+\s*\n

VS code is using javascript regular expressions
