I am trying to work out some way to make rcdefaults() work with the traited
config. Along the way, I discovered this in mplconfig:
class mathtext(TConfig):
cal = T.Trait("['cursive']", mplT.FontPropertiesHandler())
rm = T.Trait("['serif']", mplT.FontPropertiesHandler())
tt = T.Trait("['monospace']", mplT.FontPropertiesHandler())
it = T.Trait("['serif'], style='oblique'",
mplT.FontPropertiesHandler())
bf = T.Trait("['serif'], weight='bold'", mplT.FontPropertiesHandler())
sf = T.Trait("['sans-serif']", mplT.FontPropertiesHandler())
use_cm = T.true
fallback_to_cm = T.true
I dont think that will work. One of the highlights of the new config files is
that when a file says:
[mathtext]
rm = ['serif', 'sans-serif']
you actually get a list, not a string, to pass to
mplT.FontPropertiesHandler(). I discovered the code by trying to do this:
rcParams.update(rcParamsDefault)
Another thing about T.Trait to keep in mind:
T.Trait("['cursive']", mplT.FontPropertiesHandler())
"['cursive']" is the default value and is *not validated*. Nor is it
necessarily an allowed value. For example:
T.Trait('small', 'medium', 'large')
'small' is the default value, but any future attempt to set that trait
to 'small' will fail. Only items following the default are allowed.
T.Trait('small', 'small', 'medium', 'large')
Now 'small' is a valid setting.
