Is it possible to sum which result as 2 by using regexp and writing
the result line below all lines checked ?
Well, you can sum them in pure vim with either of the following
(depending on whether your vim was built with +float so you'd
have to check your :ver output) one-liners (if they line-break,
rejoin them)
:let tot=0|g/\d\+\%(\.\d\+\)\=/let
tot+=str2float(matchstr(getline('.'), '\d\+\%(\.\d\+\)\='))
or if it wasn't built with +float you can still sum integers:
let tot=0|g/\d\+\=/let tot+=matchstr(getline('.'), '\d\+')
You can then use "tot" for whatever you want (inserting into the
file, just echoing it, using it as a count later on, whatever)
