2020-01-15 08:13:09 -0500 | marked best answer | get all the active namespaces rospy | roscpp In my project, multiple robots may be spawned both at launch and at runtime, each under a certain namespace. Generally, that is I need to programmaticaly retrieve a list of namespaces currently active from a node that is in the global namespace. That must be like that. So this leads me into thinking that there is a way to do so. I'm mostly using Python, but for this purpose only I would also be willing to use a C++ node. EDIT: I've marked what I would like to retrieve from the above piece of output. |
