Autocompletion in zsh failes

[Fildo7525]

When I used ros2 Foxy on Ubuntu 20.04 in zsh everything was ok. Now I changed to Ubuntu 22.04 and to Humble and the autocompletion is not working for ros2

Same issue?: ros2/ros2cli#534

However, for me Foxy/Galactic on 20.04 is spotty at best as well

I had the same issue that the current ticket describes (env: Ubuntu 22.04+Humble) and the solution came from the issue referenced by @mjbogusz. Thanks!

By adding these lines to .zshrc the argcompletion is succesfully enabled.

# argcomplete for ros2 & colcon
eval "$(register-python-argcomplete3 ros2)"
eval "$(register-python-argcomplete3 colcon)"

Note: If the registration fails, check whether your python environment has the argcomplete package installed.

@Fildo7525 @endrelaszlo @mjbogusz either of you guys, would you mind if trying ros2/rosidl#702 to see if the problem can be solved?

endrelaszlo your comment (https://github.com/endrelaszlo) worked. The only thing I would add is to put this lines before sourcing ros.

It also worked for me (Ubuntu 22.04 / Rolling), but only if I put it after sourcing ROS. So if somebody else runs into this issue, maybe try both options 🤷

This works for jazzy / ubuntu 24.04 with zsh

argcomplete for ros2 & colcon in zsh

eval "$(register-python-argcomplete ros2)"
eval "$(register-python-argcomplete colcon)"
