While a verb like cd can easily be contributed to the ros2cli tools the question is what should the semantic of that command be? In ROS 1 when using the devel space it brought you to the source folder of a package. In ROS 2 there is no concept of a devel space and after installing a package there is no correlation to the source space anymore. So the only possible location to switch to would be the install prefix of the package or the location where the package manifest is (in the subfolder share/<pkgname> in the install space). I am just not sure how useful that would be...

It has not been implemented yet. It is likely that we will implement a command like that since many people find it useful. The underlying capabilities are definitely available from ament. (Try src/ament/ament_tools/scripts/ament.py list_packages ./src)

A contribution of a verb cd for the ros2 command would be appreciated. This is probably an easy way to get involved if anyone is interested.

I will see what I can do and if it makes sense to do it.
