How to work on a stack's trunk

If you are a developer and want to work on the trunk branch of a stack, you can check out the trunk of that particular stack, and use latest for every other stack.

To check out the trunk:

svn co https://code.ros.org/svn/ros-pkg/stacks/mystack/trunk ~/ros/mystack

Set your ROS_PACKAGE_PATH so that the stack that you are working on is *first*, e.g.

export ROS_PACKAGE_PATH=~/ros/mystack:~/ros/pkgs
