Hi,
is there a way (possibly in Python) to call the command line command rosmsg show from code, passing as an argument the name of the message/service and getting an object representing the message/the class with the message structure? I know that some commands can be called from rospy (as rostopic list, for example), but I can't find how to run rosmsg.
The command line tool calls a single function ( https://github.com/ros/ros_comm/blob/... ) which you can call directly in Python.
You could also call any API which is using behind this directly, e.g. rosmsg_cmd_show ( https://github.com/ros/ros_comm/blob/... ).
Great, that was exactly what I was searching for, although I thought messages were managed in a more object-oriented like structure. Anyway, that worked perfectly. Thanks!

What do you really want to achieve? This sounds like an xy-problem
I need to build instances of all the ros messages and services in a KB, so I need to understand which are all the messages/services being published, and which re their structures in terms of submessages/primitive types.
