Editing that way seem is bass ackwards -- probably more code
would needed to interface with readline than just implementing
it in ed. As a one line version requires just line movement
commands, there is no reason why you can't use full power of
vi through a narrow window - such as d} to delete to the end
of para and have the next line dispayed. Readline wouldn't
help there. And readline weighs in @ 28K LOC to ed's 3.5K (on
plan9 it is under 1.6K).
I think what Ralph wants is something like
"LINES=1 vi"
but without clearing the screen so that commands that
are cursor relative can work. rlwrap and readline don't
edit the current line in the file, only the command input.
OK, that I can understand. It's ages since I played with
readline, but I think you can preload the buffer it works on
(bash does that, no?) so ed + readline could be made to work
that way. I already have too many side projects on my plate, or
I'd try it. :-)
Ditto!
