Allows to change the log level at compile time.

Sorts the maps as per the sort specs (compile time or runtime).

sort specs can be implicit, explicit or mixed:

• [:dob, :name] - implicit ≡ [asc: :dob, asc: :name]
• [:dob, desc: :name] - mixed ≡ [asc: :dob, desc: :name]
• [asc: :dob, desc: :name] - explicit

Examples

iex> require MapSorter
iex> people = [
...>   %{name: "Mike", likes: "movies" , dob: ~D[1992-04-15]},
...>   %{name: "Mary", likes: "travels", dob: ~D[1992-04-15]},
...>   %{name: "Ann" , likes: "reading", dob: ~D[1992-04-15]},
...>   %{name: "Ray" , likes: "cycling", dob: ~D[1977-08-28]},
...>   %{name: "Bill", likes: "karate" , dob: ~D[1977-08-28]},
...>   %{name: "Joe" , likes: "boxing" , dob: ~D[1977-08-28]},
...>   %{name: "Jill", likes: "cooking", dob: ~D[1976-09-28]}
...> ]
iex> fun = & &1
iex> MapSorter.log_level(:info) # :debug → debug messages
iex> sorted = %{
...>   explicit: MapSorter.sort(people, asc: :dob, desc: :likes),
...>   mixed:    MapSorter.sort(people, [:dob, desc: :likes]),
...>   runtime:  MapSorter.sort(people, fun.([:dob, desc: :likes]))
...> }
iex> MapSorter.log_level(:info) # :info → no debug messages
iex> sorted.explicit == sorted.mixed and
...> sorted.explicit == sorted.runtime and
...> sorted.explicit
