Hi,
I've been playing a lot with interact recently -- I *really* like it.
While attempting to develop a step-at-a-time example of Newton-Raphson,
a couple of things came to mind.
1. What do you think about a control that saves state between
interactions, but does not give you any visible control widgets?
I know you can save state using globals, but if this works without
too much trouble, it might be cleaner. In fact, I have an implementation
now that seems to work, that allows things like:
@interact
def _( a = save_state(i=0), b = ['Go'] ):
a.i += 1
print 'i=', a.i
'a' does not appear as an interactive widget.
Every time you press 'Go' you get the next number.
Only minor testing do far, so I don't know about all the repercusions...
2. What about a similar kind of thing, but gives you access to
all the controls, so perhaps your function could change
default values, reposition sliders, etc. Perhaps something
like
@interact
def _ ( f = sin(x), range=(0..20), controls=interact_controls() ):
...
controls['range'].set_value(...)
The value of controls could be a dictionary indexed by variable name ...
If this has any worth, I could attempt a proof-of-concept in a couple of
days.
cheers
