Register variables in a dynamic reconfigure server and run the server on the fly. No more .cfg files and CMakeLists.txt tinkering!
Example:
import rospy
from ddynamic_reconfigure_python.ddynamic_reconfigure import DDynamicReconfigure
def dyn_rec_callback(config, level):
rospy.loginfo("Received reconf call: " + str(config))
return config
if __name__ == '__main__':
rospy.init_node('test_ddynrec')
# Create a D(ynamic)DynamicReconfigure
ddynrec = DDynamicReconfigure("example_dyn_rec")
# Add variables (name, description, default value, min, max, edit_method)
ddynrec.add_variable("decimal", "float/double variable", 0.0, -1.0, 1.0)
ddynrec.add_variable("integer", "integer variable", 0, -1, 1)
ddynrec.add_variable("bool", "bool variable", True)
ddynrec.add_variable("string", "string variable", "string dynamic variable")
enum_method = ddynrec.enum([ ddynrec.const("Small", "int", 0, "A small constant"),
ddynrec.const("Medium", "int", 1, "A medium constant"),
ddynrec.const("Large", "int", 2, "A large constant"),
ddynrec.const("ExtraLarge", "int", 3, "An extra large constant")],
"An enum example")
ddynrec.add_variable("enumerate", "enumerate variable", 1, 0, 3, edit_method=enum_method)
# Start the server
ddynrec.start(dyn_rec_callback)
rospy.spin()Try the example with rosrun ddynamic_reconfigure_python example.py. Run rosrun rqt_reconfigure rqt_reconfigure to play with the values.
You also have a couple of examples using it inside of a class in the scripts folder.
