VIM solutionsolutions
There's two solutions: one is via automating Ctrla keypress over a selection, second is via executing a pattern replacement with submatch(0)+1 over the selection. First the key automation.
Start by creating your list:
1. foo
2. bar 100%
3. kittens
4. eat cake
5. unicorns
6. rainbows
Insert an entry
1. foo
2. bar 100%
3. kittens
4. eat cake
4. sunshine
5. unicorns
6. rainbows
Position your cursor onto 4. sunshine and from command mode press shift + v, then shift + g . This is visual selection till the end of file. You can also move the cursor to the end of a block in the usual ways.
Press : to enter command mode, and you will see this: :'<,'> . Now type in the following:
norm Ctrl+V Ctrl+A
What Ctrl-v and ctrl-A do, is they allow you to enter "exact" key, so it will change into ^A , highlighted. This is basically saying for all lines selected, execute in normal mode keypress Ctrl-A , and Ctrl-A by default increments the number under cursor. You will see the numbers change
Solution in action:
Before
After
Another way would be to select everything from the first repeated number like before( Shiftv, then G ), and go into command mode to execute:
:'<,'>s/\v(^\d+)\./\=(submatch(0)+1).'.'/
