Comment(by jason):
P.S. I can see why having
{{{
@interact
def plotfunction(f=input_box('x^2')):
print f
}}}
produce x^2 in the input box would be good too, though. There are lots of
types in Sage for which repr does not give you back a string that can be
used to reconstruct the object. For example, I believe that after the
patch,
{{{
@interact
def plotfunction(f=input_box(RIF(3.2,3.4))):
print f
}}}
will produce an input box that has "3.3?" in it (without quotation marks).
Of course, this is nonsense. For that reason, I can see changing how
default values are handled to allow:
{{{
@interact
def plotfunction(f=input_box('RIF(3.2,3.4)')):
print f
}}}
to produce an input box with "RIF(3.2,3.4)" (without quotation marks) in
it. This means that to make an input box containing a string (with
quotation marks), you'll have to do something like:
{{{
@interact
def plotfunction(f=input_box("'my string'")):
print f
}}}
(i.e., double-quote your string).
