Though not mentioned much in the tulip discussion, tkinter is a third
'T' package with its own event loop. (And by the way, I associate
'tulip' with 'Floriade', with 10s of thousands of tulips in bloom. It
was a +++ experience. But I suppose it is too cute for Python ;-)
Yesterday, tk/tkinter expert Kevin Walzer asked on python-list how to
(easily) read a pipe asynchonously and post the result to a tk text
widget. I don't know the answer now, but is my understanding correct
that in the future a) there should be a tk loop adapter that could
replace the default tulip loop and b) it would then be easy to add i/o
events to the tk loop?
My personal interest is whether it will some day be possible to re-write
IDLE to use tulip so one could edit in an edit pane while the shell pane
asynchronously waits for and displays output from a 'long' computation.*
It would also be nice if ^C could be made to work better -- which is to
say, take effect sooner -- by decoupling key processing from socket
reading. I am thinking that IDLE could be both a simple test and
showcase for the usefulness of tulip.
*I currently put shell and edit windows side-by-side on my wide-screen
monitor. I can imagine putting two panes in one window instead.
