These are shim packages for ros_gz
that redirect executable calls to the related ros_gz
executable.
These require ros_gz
to be installed though, but are set up to depend on ros_gz
.
This allows users to do either of these and get equivalent behavior:
ros2 run ros_gz parameter_bridge [...]
ros2 run ros_ign parameter_bridge [...] # Will emit deprecation warning
Additionally, installed files like launch files, message interfaces etc. are duplicated versions of the ones in ros_gz
(but renamed as appropriate), and point to ros_gz
dependencies as well (e.g. launch files pointing to ros_gz
nodes.)
