Regex for # and text between # and trailing whitespace

Question

I am trying to get regex for:

• Get "#" and all text between "#" and trail ending "\t"(whitespace).

So far I have:

/#[a-zA-Z0-9]\t/

This seems wrong? What can I do to fix it?

Answer 1

If by whitespace you mean actual whitespace (that is spaces, tabs, etc), then this does it:

/#\S+/

^{(\S is equivalent to [^\s])}

If you however meant tabs, when you wrote whitespace, then this:

/#[^\t]+/
