launch file parameters that have curly braces
I am using ROS Melodic.
How can I set a parameter in a launch file that resembles a yaml syntax like this:
scan: {sensor_frame: base_scan, data_type: LaserScan, topic: scan, marking: true, clearing: true}
I know that generally, when there are parameters like:
SOMETHING:
key: value
foo: bar
it's sufficient to do <param name="SOMETHING/key" value="value" />
, but I don't think it's the same for the curly braces, or is it?
