Re: substitute() regex trim last newline from register ?

Tim, hi

ok, awesome.

I think this works now -

"aygv<Esc>:let @* = substitute(@a, "\\_s\\+$", "", "")<CR>

thx so much!

Pretty sure you're 99% of the way there:

 let @+ = substitute(@a, '\n\+$', '', '')

If you want all potential trailing whitespace (spaces, tabs, and
newlines)

 let @+ = substitute(@a, '\_s\+$', '', '')

should do the trick.
