Much like in ROS 1, ROS 2 nodes’ command line is evolving to allow passing parameters via key-value pairs. In this case, however, remapping rules and parameter assignments need further disambiguation. This drove several discussions, about CLI arguments syntax and how it affects usability, that have yet to conclude.
At this point, we’d very much appreciate your feedback, either on this post or on this pull request, to make sure the end result is comprehensive enough of the varying ways in which you use (or would like to use) this ROS 2 feature - to land in Eloquent -.
