Re: remove all except pattern

Hi,

Thank you for replying.

I use this command to put all matches on a new line:
:let @a=""<CR>:%s//\=setreg('A', submatch(0), 'l')/g<CR>:%d _<CR>:put
a<CR>:0d _<CR>

I can't find out how to keep them on the same line.

I tried this command:
%s/\(^\|\(hello\)\@<=\).\{-}\($\|hello\)\@=//g

It works with text but not with p.e. emails:
it removes the last character of every email. I tried many things to
change the command but I suppose I don't understand enough about
vimscript to find the solution.

Regards, R.
