NOTE(allen): Things I learned from this experiment.
|
|
|
|
First of all the batch edits aren't too bad, but I think
|
|
there could be a single system that I run that through that
|
|
knows how to build the batch edit from slightly higher level
|
|
information. For instance the idea in point 2.
|
|
|
|
Secondly I definitely believe I need some sort of "mini-buffer"
|
|
concept where a view sends commands so that things like
|
|
pasting still work. Then the contents of the "mini-buffer"
|
|
can be used to complete the edits at all cursor points.
|
|
This doesn't answer all questions, because somehow backspace
|
|
still wants to work for multi-lines even when the "mini-buffer"
|
|
is emtpy. Such a system would also make it possible to send
|
|
paste commands and cursor navigation to interactive bars.
|
|
|
|
Thirdly any system like this will probably not want to
|
|
operate through the co-routine system, because that makes
|
|
sending these commands to the "mini-buffer" much more
|
|
difficult.
|
|
|
|
Fourthly I desperately need some way to do multi-highlighting
|
|
multi-cursor showing but it is unclear to me how to do that
|
|
conveniently. Since this won't exist inside a coroutine
|
|
what does such an API even look like??? It's clear to me now
|
|
that I may need to start pushing for the view routine before
|
|
I am even able to support the GUI. Because that will set up the
|
|
system to allow me to think about the problem in more ways.
|
|
|
|
Finally I have decided not to pursue this direction any more,
|
|
it just seems like the wrong way to do it, so I'll stop without
|
|
doing multi-cursor for now.
