it's easy stuff actually :) It works like this: I modified the viper-prefix-arg-com function to introduce 4 new commands: da di ca ci. These commands will read-char to get motion command.
Yes, this is a very good way to do it. It means more objects can be easily added without any more mucking around in `viper-prefix-arg-com'. Anyway, I mailed Michael Kifer and asked if there was a way to avoid redefining `viper-prefix-arg-com', and he replied he couldn't think of one. So until the original function is redesigned, which will probably not happen any soon, I think we can hold on to the present approach. :) What now remains is copying commands, `yiw', `yas', etc., and visual commands like `viw' and `vas'. The former requires updating `viper-prefix-arg-com' with entries for `vimpulse-yi' and `vimpulse-ya', while the latter is just a matter of writing commands for moving the cursor. For example, `vas' moves the cursor one sentence forward if it's at the end of the selection, and one sentence backward if it's at the beginning. I think this illustrates another point, incidentally: the power of vi comes from the multitude of ways of combining very basic commands, but implementing those combinations requires lots and lots of code. Therefore I think building vimpulse.el on top on Viper, rather than implementing Vim emulation from scratch, is the better approach.
