Re: [ros-users] ROS 1.3.0 Released

Hi Daniel,

Diamondback is not due until February, so there are several months in
which rosjava can be migrated forward before a 'stable' release lands.
My understanding is that the maintainers will try to migrate rosjava
forward, but I do not wish to make promises on their behalf as they
are external contributors.

Judging from efforts with roscpp and roslisp, it should not be a
significant effort to perform this rewrite (<1 week of effort). Josh
cleaned up the Python libraries a bit when he did the roscpp
generators, so there's a good starting point (i.e. use genmsg_cpp.py
or genmsg_lisp.py, do *not* use genmsg_py.py as a starting point).
Given that there is a pre-existing message generator to compare
outputs against, it might be a task that you could take on.

regards,
Ken
