I am terrible at writing vim regular expressions. Whenever I write one to do a substition, it never works the first time because I inevitably end up writing something Perl instead of vim. I fare a lot better when doing a simple search because I have incsearch turned on and I can see in real-time whether my pattern matches.
Is there a way I can have the s command act like / (performing an incremental search) while I am attempting to write a proper pattern?
I’m not sure but I think there is not a way to do it. By the way, I use a little trick to speed up my substitutions. If you do something like:
on the command line Vim will use your latest search. So, it’s not exactly what you need but still a way to increase a bit your speed doing substitutions.
