rosjson: rosjson

rosjson is a Python library for converting ROS messages to JSON (JavaScript Object Notation) representation.

Homepage: http://ros.org/wiki/rosjson

rosjson is a simple ROS message to JSON converter.

ROS messages are represented as a dictionary, where each field is a ROS message field. The conversion of types is as follows:

• primitive types { integers, floats, booleans, strings } -> JSON primitives
• time, duration -> JSON float (time in seconds)
• arrays -> JSON lists
• message -> JSON dictionary

Code API

rosjson has only 2 API methods, which are equivalent for converting messages. The rosjson.ros_message_to_json() constrains the type to a rospy.Message instance, whereas rosjson.value_to_json() will convert any valid rospy type.

rosjson.value_to_json(val)
