Regular expression: easier "find empty lines"

[Stefan]

The RegEx ^$ find empty lines.

But to replace them by nothing (to delete empty lines)
you have to search for line enders too: ^$\r\n

Other editor delete empty lines just simply by
Find: ^$
Replace:

I guess they add those EOL char at there own, without user access???
Maybe you want to do the same. Just if you once rewrite your regex engine, please think about this behavior.

Hello Stefan,

I think reason for such "non-standard" behavior, is same as problems with greedy search - I am trying to emulate text stream from array of single lines.

So probably when I would fix problem with greedy search, this would also gone. But I would check any way, and if it is easy would implment it with current logic (if this would no require big changes).

Thanks for suggestion

Hi once more,

which other editors you mean? I have tested several (EditPlus, Notepad++) but none of them works as you have described, but does it like hippoedit (mostly).

So now I am not sure, that this is a good solution... Because it is not standard and can be a surprise for user

    right now all editors i test didn't support this. 
Perhaps this was an dream only, because it is logically ?

Only VIMs :g/^$/ d and SEDs "/^$/d" (and perhaps PERL) do that.

So i was wrong, sorry.
