Adding/generating content automatically in Vim

Question

I have a huge list of numbers and I would like to add content on the end of each line. It's something like this:

Before:

After:

A couple of points:

I know that :range s/oldpattern/newpattern/ will substitute the oldpattern by the new one.
I know that for i in range(begin, end) | something | endfor can generate those extra numbers.

However, I don't know if it's possible to combine them to do what I want (or if there's a different way to do it). Does anybody knows how can I add those extra values automatically? I'm quite sure that it's possible using Vim, but I don't know how.

You can do this by visually selecting the area then typing

:s/$/\=', '.(line('.')-line("'<")+1)<CR>

(range is added automatically when you type : from visual mode). Visual mode is needed to get line("'<") thing, if you are fine with typing line number in place of it use any range.

I'd do

:%!nl
:%s/\v^\s*(\d+)\s+(.*)$/\2, \1/g

nl will (by default) skip numbering empty lines

Or as a oneliner

:exec "%!nl"|%s/\v^\s*(\d+)\s+(.*)$/\2, \1/g

Note that nl does not number blank lines, so it may be necessary to use nl -ba, depending on the desired behavior.

:%!awk '{print $0", "NR}'

or

:%!perl -lpe '$_.=", $."'
