List processing and remove by regex issue

[shabbysquire]

Not sure if a bug...

In list processing > remove by regex, I use \W (capital w), which is opposite of \w which match any alpha-numeric character, digit, or underscore.

\W wipes out all my data in the list - alpha-numeric.

Slightly related; how do I regex all empty lines in list by regex? I've used: \f \n \r \s \t, but none of them deletes the empty lines.

Thanks.

It's not bug. Any space or \n \r will count within \W

Try ^\s*$

Tried to delete empty lines with all above regex, and ^\s*$, but nothing works.

Now have to write to file using: list processing > add text (no issues with spaces).

Attach your file that you bind where this regexp doesnt work
