Comment (by vbraun):
Also, the *handled* options should have their value checked, and not just
fail when they are in the process of being drawn on the screen.
The right solution imoh is by introducing infrastructure for "option
dictionaries with validation". I made a simple version for the display
preferences, for example
{{{
sage: from sage.repl.rich_output.preferences import DisplayPreferences
sage: d = DisplayPreferences(text='latex')
sage: d
Display preferences:
* graphics is not specified
* text = latex
sage: d.text
'latex'
sage: d.text = 'coocoo'
---------------------------------------------------------------------------
ValueError Traceback (most recent call
last)
<ipython-input-12-45e65af2b5e2> in <module>()
----> 1 d.text = 'coocoo'
/home/vbraun/Code/sage/local/lib/python2.7/site-
packages/sage/repl/rich_output/preferences.pyc in setter(self, prefs,
value)
230 if value not in allowed:
231 raise ValueError('value must be unset (None) or one of
{0}, got {1}'
--> 232 .format(allowed, value))
233 setattr(prefs, self.underscore_name, value)
234
ValueError: value must be unset (None) or one of ('plain', 'ascii_art',
'latex'), got coocoo
sage: d.heyhey
---------------------------------------------------------------------------
AttributeError Traceback (most recent call
last)
<ipython-input-13-2956b69fb951> in <module>()
----> 1 d.heyhey
AttributeError: 'DisplayPreferences' object has no attribute 'heyhey'
}}}
