Python
Wildcard Subscriber
>>> from ros_wild import Subscriber
# subscribe to all Log topics
>>> sub = Subscriber(r"/rosout.*")
>>> sub.subscribed_topics
['/rosout', '/rosout_agg']
# unsubscribe from all topics
>>> sub.unregister_all()
>>> sub.subscribed_topics
[]
# resubscribe to topics
>>> sub.reload_topics()
>>> sub.subscribed_topics
['/rosout', '/rosout_agg']
Register Callback
>>> from ros_wild import Subscriber
>>> from std_msgs.msg import Bool, String
>>> def callback_bool(msg):
>>> print("bool is {}".format(msg.data))
>>> def callback_string(msg):
>>> print("string is {}".format(msg.data))
# subscribe without callback
>>> sub = Subscriber(r".+")
>>> print("Subscribed topics are {}".format(sub.subscribed_topics))
Subscribed topics are ['/bool/01', '/rosout', 'rosout_agg', '/string/01']
# register callback
>>> sub.register_callback(Bool, callback_bool)
>>> sub.register_callback(String, callback_string)
>>> print("Topics with callback are {}".format(sub.topics_with_callback))
Topics with callaback are ['/bool/01', '/strings/01']
Wildcard Publisher
The code below will publish Log message to /rosout and /rosout_agg topics.
>>> import rospy
>>> from ros_wild import Publisher
>>> from rosgraph_msgs.msg import Log
# publish to all topics
>>> rospy.init_node("test")
>>> pub = Publisher(".*", queue_size=1)
>>> pub.published_topics
['/rosout', '/rosout_agg', '/tf', ... ]
>>> pub.publish(Log(msg="this is test message"))
