Allow `sentence=True` in NestedCompleter #1400

Open mmatthebi opened 3 years ago

mmatthebi commented 3 years ago

Given a complete dict like 

{ 'a': { 'b.c.d' } }

for NestedCompleter does not allow completing after typing a b., because the WordCompleter for b. doesn't use sentence=True.

Is it possible to have sentence=True as a default or a configuration option?

A problem I encountered (probably caused by missing sentence=True in NestedCompleter too) is that, in addition to not completing after the first non-letter character, it shows wrong completions.

for example, consider this dict

{
    '/an-option': {'on', 'off'},
    'an-strange-option': {'yes', 'no'},
    'another-option': {'some', 'nested', 'option'}
}

writing / on prompt will show /an-option as expected... but writing /an do not show /an-option and shows instead an-strange and another, and this does not occur in WordCompleter when called with sentence=True.
