How can I ignore some folders in my ROS_PACKAGE_PATH?
I have a folder in which is in my ros workspace which has ~300GB of data spread over many subfolders. And because of this, every single ROS node takes an age to start up (including roscore).
I moved all the data into an external folder not in my ROS_PACKAGE_PATH and everything started up quickly as before.
Now, I have to decide between changing the way the code works or finding a simple way to ignore packages on my ROS_PACKAGE_PATH. Is there something similar to a ROS_NOBUILD flag for this?
