%config TerminalInteractiveShell.xmode='Minimal' doesn't apply changes

[switowski]

Hi,

either I'm doing something stupid or the following way of setting the xmode doesn't seem to work:

%config TerminalInteractiveShell.xmode='Minimal'

It doesn't change the xmode (while just doing %xmode verbose works perfectly fine):

In [1]: %config TerminalInteractiveShell.xmode = 'Minimal'

I have also tried to change the setting of %config IPCompleter.backslash_combining_completions and this worked perfectly fine.

In the meantime you can just use the xmode magic, but yes we woudl need to hook things correctly to propagate the config change.
