Mechanism to query current config #9
Description
The :Glaive command makes it handy to update flag values, but we currently don't have a user-level interface for checking current flag values (calling functions like :echo maktaba#plugin#Get('someplugin').Flag('someflag') doesn't count as a user-level interface).
Many vim commands like :set, :let, :command, :map, etc. have a no-arg version that spits out the current config. Glaive should adopt a convention like this to let people query/explore their plugin config.
This could entail a :Glaive command to list all flags and their values by plugin, a :Glaive SOMEPLUGIN command to list flags for an individual plugin, and :Glaive SOMEPLUGIN SOMEFLAG to show the current value of an individual flag.
