ddynamic_reconfigure

ROS2 port of the ddynamic_reconfigure ROS1 package in order to facilitate a smooth transition from ros1 to ros2. Not everything is ported but the API should be more or less consistent for a relative easy port of your ros1 app to ros2.

If you are looking for a dedicated solution, it might be better to check out alternatives, e.g. https://github.com/PickNikRobotics/generate_parameter_library

Example

$ ros2 run ddynamic_reconfigure fake_dynamic_reconfigure_server 
double_test 0
double_range_test (0..10) 2
int_test 0
bool_test 0
str_test
