ros2 command line autocomplete interface

edit

Hello everyone!

I'm going through the ROS2 tutorials and I've bumped against this in the topic and service pages. I'm trying to publish a message and use autocomplete to get a template of the .srv call. Good old ROS1 would create a valid cmd line field.

But in ros2 I get:

$ ros2 service call /spawn turtlesim/srv/Spawn x:\ 5.0\
y:\ 5.0\
theta:\ 0.0\
name:\ \'\'\ 
Traceback (most recent call last):

           ^

In fact, the tutorials themselves suggest using JSON syntax, which the autocomplete doesn't provide.

Am I missing something here or it's a known omission?

Thanks!
