[ROS2] What is the "rqt --force-discover" option meaning?
Hello, experts. My environment is Ubuntu 18, ROS2 Crystal.
I installed the rqt-graph plugin to debugging. But, I can't find out the plugin on rqt-gui. In normal case, It should to be on "Plugins->introspection->Node Graph".
After $ rqt ---force-discover
, it is working now.
Further, other plugins come out on "Plugins" tap.
What is the "rqt --force-discover" option meaning?
The description, written on the rqt usage guide, said below.
"--force-discover force a rediscover of plugins"
Do you explain "rediscover" progress meaning?
