# JSONPatch

JSONPatch is an Elixir implementation of the JSON Patch format,
described in [RFC 6902](http://tools.ietf.org/html/rfc6902).

Examples:

    iex> JSONPatch.patch(%{"a" => 1}, [
    ...>   %{"op" => "add", "path" => "/b", "value" => %{"c" => true}},
    ...>   %{"op" => "test", "path" => "/a", "value" => 1},
    ...>   %{"op" => "move", "from" => "/b/c", "path" => "/c"}
    ...> ])
    {:ok, %{"a" => 1, "b" => %{}, "c" => true}}

    iex> JSONPatch.patch(%{"a" => 22}, [
    ...>   %{"op" => "add", "path" => "/b", "value" => %{"c" => true}},
    ...>   %{"op" => "test", "path" => "/a", "value" => 1},
    ...>   %{"op" => "move", "from" => "/b/c", "path" => "/c"}
    ...> ])
    {:error, :test_failed, ~s|test failed (patches[1], %{"op" => "test", "path" => "/a", "value" => 1})|}
