Putting that in your command gives an empty output (it removes the
emails).
Ah...with that context, I might try to approach the problem
differently. If you don't mind newlines being added when more
than one email was on the same line, I might do something like
:%s/\([A-Z0-9+_.-]\+@\([A-Z0-9-]\+\.\)\+[A-Z]\{2,6}\)/\r&\r/g
:v/^\([A-Z0-9+_.-]\+@\([A-Z0-9-]\+\.\)\+[A-Z]\{2,6}\)$/d
The first one puts each email address alone on a line, and the
second one deletes all lines that don't have an email address on
them. Given your example, one might also have to add "\c" to
your pattern to make it case-insensitive (your regexp only finds
uppercase email addresses).
If you need to keep emails on the same line back together,
it might take a little more work.
I can't find out how to keep them on the same line.
(reordering to the preferred interleaved-reply format)
My 2-pass could be modified something like a multiple-pass,
generically written as something like
1) :%s/^.\{-}\(<pattern>\)/\r- \1\r/
2) :v/^- <pattern>/s/<pattern>/\r&\r/g
3) :v/<pattern>/d
4) :v/^- /-j
5) :%s/^- /
where
1) pulls the first match in each line, deletes the stuff before
the match, prefixes it with something unique (using "- " here)
2) on all the non-prefixed lines, do the previous step to put
each match on its own (non-prefixed) line
3) delete the lines that don't match the pattern, leaving just
matching lines (with the first-matches having prefixes)
4) on lines without prefixes, join to the previous line
5) strip the prefix back off
For your email example, that would be:
:%s/^.\{-}\([A-Z0-9+_.-]\+@\([A-Z0-9-]\+\.\)\+[A-Z]\{2,6}\)\c/\r-
\1\r
:v/^-
\([A-Z0-9+_.-]\+@\([A-Z0-9-]\+\.\)\+[A-Z]\{2,6}\)\c/s/\([A-Z0-9+_.-]\+@\([A-Z0-9-]\+\.\)\+[A-Z]\{2,6}\)\c/\r&\r/g
:v/\([A-Z0-9+_.-]\+@\([A-Z0-9-]\+\.\)\+[A-Z]\{2,6}\)\c/d
:v/^- /-j
:%s/^- /
There might be some way to do it in fewer steps, but if you need
something right now, that should work.
