I don't think Vim does have an understanding of functions. It knows about { or
} in the first column (the [[ and ][ motions which you're using in your
mapping).
Also, your example mapping:
onoremap if :<C-U>normal! [[vi{<cr>
On your example text:
template <typename Stream>
void do_read( Stream& stream, std::vector<char>& buf )
{
boost::asio::async_read(
stream, boost::asio::buffer( buf ), boost::bind( read_handler ));
stream.get_io_service().reset();
stream.get_io_service().run();
std::cout << "done" << std::endl;
}
Only selects 7 lines, unless there is a space character after the opening {.
...I see why.
I have 'selection' set to "exclusive". If I change it to "inclusive" then I get
8 lines.
Looking at WHAT gets copied with yif leads me to the following solution:
onoremap if :<C-U>normal! [[vi{h<cr>
This will work if 'selection' is set to "inclusive". If "exclusive" then you
need to leave off the h as you did before. If you want to make your mapping
generic you'll probably need to use an <expr> mapping which checks the value of
the 'selection' option.
