Two ways of doing this sort of thing are:
This will add a newline and four spaces of "indent" before every matched
\) around the search expression
/foo/ capture the match into a group, and then the
\1 uses the captured group in the replacement. This obviously isn't necessary for simple values of
You can also do this with the
:global commands. For example the following command will indent all lines that match the regexp
/foo/ and add a line above them:
This works similar to a
:substitute command, but instead of making a substitution, it applies the normal mode operations indent (
>>) followed by add a line above (
O) to each matching line.
You can adjust the normal mode commands to perform different operations as necessary.

I'm a little unclear on precisely what you're trying to achieve, but if the goal is to e.g. turn this:
^^^^ <- one level of indent
I'd do so with the following two commands:
If, for some reason, you need to add a specific number of spaces that doesn't match your shiftwidth settings, you could instead do:
^^^^ <- type four spaces after the `i`
In practice, for the specific case mentioned above, I'd probably have used a recursive macro:
qqq: Clear out the
q register. Necessary for recursive macros,
qq: Start recording in the
/;[^$]<cr>: Find the first semi-colon not followed by a newline,
:left<cr>: Remove any existing indentation (to remove automatic indentation),
>>: Add one level of indent,
na<cr><esc>: Jump back to the semi-colon,
q: Finish recording,
@q: Run the macro.
You could also record a macro that runs on a single line and then apply it to every line with the global command.
The macro versions look complicated written down, but because they just use normal editing commands recording them comes naturally (with a bit of practice) and using them is a lot faster than it looks.
