Usage

This shard monkey patch JSON::Any, YAML::Any and CON::Any to extend them by adding this following methods, which are equivalent for those fround in Hash and Array.

The main difference is the argument, which accept an Enumerable which represents a path in the document.

The available methods are:

#[](path : Enunerable)

#[]?(path : Enumerable

#[]=(path : Enumerable)

#delete(path : Enumerable)

Example

require "dynany/json"

json = JSON.parse %({"hash": {"array": ["first", "second"]}})
json[["hash", "array", 1]]       # => "second"
json.delete ["hash", "array", 1] # => {"hash" => {"array" => ["first"]}}
json[["hash", "array", 1]]?      # => nil
