Comment:
Hello,
> As I said, that is not desirable here since we might change the viewer
depending on UI capabilities.
>
> There should be some framework for keyword options, especially for
plottig options, that can deal with this. But right now we have nothing
better than passing dictionaries around, so we can't easily validate if
'''some''' viewer uses an argument or not.
We do not have to validate it in this function. Here is an example
{{{
def viewerA(some_option=4):
print "Plot with some_option={}".format(some_option)
def viewerB(some_other_option=4):
print "Plot with some_other_option={}".format(some_other_option)
def plot(viewer="A",**args):
r"""
Plot an object with the selected viewer.
All other options are forwarded to the actual viewer. See their
documentation for more information.
"""
if viewer=="A":
viewerA(**args)
elif viewer=="B":
viewerB(**args)
else:
raise ValueError("viewer must be A or B")
}}}
As you can see no verification is done in the generic 'plot'. Then,
everything works as expected:
{{{
sage: plot("A",some_option=4)
Plot with some_option=4
sage: plot("B",some_other_option=4)
Plot with some_other_option=4
sage: plot("A",some_other_option=4)
...
TypeError: viewerA() got an unexpected keyword argument
'some_other_option'
}}}
