Expression Language function request: NOT
« on: December 22, 2020, 05:24:18 pm »

Hi Matt,
Can you please add a Not() function? The exclamation mark only works inside an if(), and I suppose that's a fluke.
It's useful to negate Regex mode 0 which returns 0 or 1, for instance, and other bool functions.

Rules:
Not(0) = 1
Not(1) = 0
Not() = 1     (empty value or whitespace)
Not(anythingElse) = 0

Thanks, and happy holidays!

I've struggled with this sort of thing occasionally too. This would be useful. +1

I'll point out that this functionality does already exist in the Math() function, but it would be nice to have it independently, as we already do with And() and Or().

Good idea.  I'll see if I can knock it off when I'm back.

Thanks :)
