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

Tony, hi

ok, thanks.  I can use 0 v $ y.  But V y is handy/quick ...

Inside of vim its all great, V works perfectly - its just I wanted to automatically remove the last newline from "* if possible, 

so that a V y and then outside of vim paste doesn't have the extra newline.

I just wondered if I could regex trim the last newline of "* or of "a and put it into "*

thanks always for your help,

-m

When yanking linewise, what you get is lines, and each of them has a
proper end-of-line. This way, when you paste it, it will be pasted
linewise, with line breaks between it and whatever happens before and
after it.

To yank without an end-of-line at the end, yank characterwise from the
first character of the first desired line (or from the first character
you want to yank even if it is in the middle of a line) to the last
character you want to yank. This way, if you paste in the middle of a
line, you won't get line breaks before and after the pasted text.

Tony.
