Condition parser in Elixir

CondParser

CondParser reads conditions like (':foo' or ("toto" == true AND (12 != 13 OR false))) and true and transform them either in an ast with parse/1, or in json with to_json/1.

Ast looks like this:

{:and_op,
  {:or_op, ":foo",
    {:and_op,
      {:eq_op, "toto", true},
      {:or_op,
        {:not_eq_op, 12, 13},
        false
      }
    }
  },
  true
}

Json looks like this:

{
  "left": {
    "left": ":foo",
    "op": "or",
    "right": {
      "left": { "left": "toto", "op": "eq", "right": true },
      "op": "and",
      "right": {
        "left": { "left": 12, "op": "not_eq", "right": 13 },
        "op": "or",
        "right": false
      }
    }
  },
  "op": "and",
  "right": true
}
