Example
Vim macros can also be recursive. This is useful for when you need to act on every line (or other text object) till the end of the file.
To record a recursive macro, start with an empty register. (A register can be emptied using q<register>q.)
Choose a consistent starting point on each line to start and finish.
Before finishing recording, invoke the macro itself as the last command. (This is why the register must be empty: so it'll do nothing, as the macro doesn't exist yet).
Example, given the text:
line 1
line 2
line 3
foo bar
more random text
.
.
.
line ???
In normal mode, with the cursor on the first line and a empty register a, one could record this macro:
qaI"<Esc>A"<Esc>j@aq
Then with a single invocation of @a, all the lines of the file would be now inside double quotes.
