Type tokens for ROS types

ROS Type Tokens

This is a small Python library that provides type tokens (objects that represent a type) for Robot Operating System built-in types and message types.

This library was initially developed as a utility of the HAROS framework, and is now distributed on its own.

What Is In The Box

This repository contains a Python package, and the respective source code, to create (manually or automatically) type tokens for the various ROS data types. Type tokens contain attributes not only of the type itself but also of any related subtypes. For example:

from rostypes import HEADER

HEADER.type_name    # 'std_msgs/Header'
HEADER.is_builtin   # True
HEADER.is_primitive # False
HEADER.is_message   # True
HEADER.constants    # {}
HEADER.fields       # {'seq': UINT32, 'stamp': TIME, 'frame_id': STRING}

assert HEADER.fields['seq'].is_number
assert HEADER.fields['stamp'].is_time
assert HEADER.fields['frame_id'].is_string

Installing

To install this package, make sure that you have Python 2.7 or greater. Simply run the command:

pip install ros-type-tokens
