[ros-users] RFC: rosworkspace

[Ken Conley]

Along those lines, what if the setup.bash includes a ROS_WORKSPACE
environment variable?

It would enable:

 * no longer have to specify path in rosworkspace commands
 * integrate with roscd
 * do things like 'alias setup=source $ROS_WORKSPACE/setup.bash'

Alternate workflow:

$ source /opt/ros/unstable/setup.bash
$ rosworkspace init /tmp/work

# sets ROS_WORKSPACE=/tmp/work
$ source /tmp/work/setup.bash

# add multiple stacks to workspace
$ rosworkspace add navigation laser_pipeline

# requires update to rosbash
$ roscd workspace

# get released version of camera_drivers instead of devel
$ rosworkspace add camera_drivers --release

# add to a different workspace
$ rosworkspace add navigation --path=/tmp/other

# enable the other workspace
$ source /tmp/other/setup.bash

$ rosworkspace delete navigation
