rqt_dep's Issues

display package info from different distro?

From @scpeters on March 8, 2016 0:46

We are approaching releasing season for ROS K, and a common question is which packages are blocking the release of other packages. The rqt_dep tool is great for visualizing package dependencies. It would be great if we could use this tool to visualize which packages have been released into a new ROS distro, to identify the blockages.

In discussing this in the past, a known complicating factor is that dependencies may change from one ROS distro to the next, so this can be an ill-posed problem in some cases.

Most of the time, though, the dependencies don't change from one distro to the next. As a first step, I would load rqt_dep with the most recently released ROS distro (jade at the moment) and would like to select another distro from a drop-down combo-box and then colorize the graph.

Any hints are welcome.

Crash in rqt_dep

I ran the program from the console; and it crashed, after I randomly selected a few checkboxes without having anything inside the package name field. This is the error message:

Show non ROS package

AFAIUC currently rqt_dep only shows ROS package (or catkin package to be more precise?). It'd be nice if it shows non ROS packages in addition.

I assume traversing packages is done by rospkg functionality, which uses information in package.xml where non-catkin package dependencies can be listed up. Since rospkg can return non-catkin? package names by e.g. RosPack.get_rosdeps, we should be able to add this functionality.

Note I don't think rospkg can find the dependency of non-catkin packages.

This doesn't have to be done in ROS ecosystem (although so far I haven't found other tools that visualize dependency tree well), but because implementation might not be that hard, I think it's worthwhile feature.
