Hello bg,
For describing the subsets you want, why not use as a bottom representation
something more connected with clojure datastructures?
Like
set literal => set of sibling keys
Vector => path to an inner key
Map => I see no usage for maps right now
Your example could then become:
#{[:name]
[:email]
[:adress #{:city :state}]
[:spouse #{:name [:address #{:city :state}]}
I don't have an implementation to offer, but as I see it, it could be some
kind of superset of get-in, extending its syntax, if you will.
What about that ?

Hi,
I have a problem wherein I need to select subsets of a given map;
think about select-keys, but with arbitrary nesting.
For example, consider this map -
(def my-map {:name "John Doe"
:email "[email protected]"
:address {:house "42"
:street "Moon St."
:city "San Francisco"
:state "CA"
:zip 76509
:mobile "+188888888"}
:ssn "123456"
:spouse {:name "Jane Doe"
:ssn "654321"
:relation :wife
:address {:house "42"
:street "Moon St."
:city "Atlanta"
:state "GA"
:zip 76509
:mobile "+188888888"}}})
>From the above map, I want to extract this sub-map -
{:spouse {:name "Jane Doe", :address {:state "GA", :city "Atlanta"}},
:name "John Doe",
:email "[email protected]",
:address {:state "CA", :city "San Francisco"}}
What would be a good way to express this sub-map so that I can pass it
on to a function?
I am thinking about something like this -
[:name :email {:address [:city :state]} {:spouse [:name {:address
[:city :state]}]}]
Example implementations are also welcome.
Regards,
BG
