How to Automatically Source devel/setup.zsh After Activating ros_env Environment?

[desstiony]

I'm working with ROS and have set up my development environment using mamba activate ros_env. However, I find myself repeatedly sourcing devel/setup.zsh every time I activate the environment to ensure that ROS packages are properly sourced in my shell. Is there a way to automate the sourcing of devel/setup.zsh upon activating the ros_env environment?

• Operating System: ubuntu22.04
• ROS Version: noetic
• Shell: Zsh

I do not know if it is a failproof method, but what we typically do in my lab is to manually add an activation script with the package activation scripts of the conda environment, something like:

echo "source $(pwd)/devel/setup.zsh" > "${CONDA_PREFIX}/etc/conda/activate.d/choose_unique_name_for_this_prefix_activate.sh"
chmod +x "${CONDA_PREFIX}/etc/conda/activate.d/choose_unique_name_for_this_prefix_activate.sh"

However, after disk the deactivate of your conda environment will not properly work anymore.
