Vim - move rest of line to new line above

How does one get from

int lel = 123; // this is a comment
               ^

to 

// this is a comment
int lel = 123;

preferably when starting in insert mode, and with the right indentation?

My current way of doing it is C-c l d$ O C-c p, but as my auto-indent isn't perfect, the inserted line in not indented at all.

I think some editors use space+enter or something for this (at least I think I've seen it).

Is this possible in vim by default?

New answer:

d^o<c-u><esc>p

Figured it out. This was one of my early attempts, but in the form <esc>d^o<esc>p, which has the problem that the inserted line gets a comment leader. <c-u> fixes that.

d^o<c-u><c-o>p

is of course useful if one wants to stay in Insert mode.

Earlier answer:

This solution works, but the answer by Randy Morris is better.

Suggested key sequence:

<esc>mpa<cr><esc>dd`pP`pa

(Where p can be replaced with any other mark.)

This means <esc> enter Normal mode, mp mark current position as p, a enter Insert mode, <cr> break the line and put the comment on the next line at the correct indentation, <esc> go to Normal mode, dd delete line, `p go to the marked position, P put the deleted line before the current line, `p go to the marked position, a go to Insert mode. To avoid wearing your fingers out, map it:

:inoremap <F2> <esc>mpa<cr><esc>dd`pP`pa

The indentation will not be correct if the comment is at the end of a line that increases or decreases indentation.

Simpler sequence that will not work on the last line in the buffer

To perform this operation on a line that isn't the last line in the buffer, the following will do. With the cursor on the first slash, in Insert mode: <cr><esc>ddkPjA.

The <cr> breaks the line and puts the comment at the correct indentation, <esc> go to Normal mode, dd delete line, k go to previous line, P put the deleted line before the current line, jA to end up in Insert mode where you were when you started.

To map it:

:inoremap <F2> <cr><esc>ddkPjA

I would probably use 

DO<c-r>"

D deletes to the end of line. O opens the line above in insert mode (with the correct indentation). <c-r>" pastes the part that was deleted with D.

(This ends in insert mode)

Still not a very pretty answer, but assuming the cursor is where the "^" is above, another option would be:

d0=:puEnter

  • d0 deletes til the beginning of the line.
  • = reindents over the next motion.
  • :pu short for :put
  • Enter to run the command.
