A tool to identify dependencies on python 2.
Project description
This is a tool for checking if your ROS package or its dependencies depend on python 2.
Install
This package works on Ubuntu and Debian, and it needs some packages installed on the system.
Install these if the default python is Python 2 (Ubuntu Bionic, Debian Stretch, etc).
$ sudo apt-get install python-apt $ sudo apt-get install python-rosdep-modules $ sudo apt-get install python-catkin-pkg-modules
Install these if the default python is Python 3 (Ubuntu focal, Debian Buster, etc).
$ sudo apt-get install python3-apt $ sudo apt-get install python3-rosdep-modules $ sudo apt-get install python3-catkin-pkg-modules
Then install from PyPI.org.
$ pip install py3-ready
If you would like to install from source then create a virtual environment with access to system packages.
$ cd py3-ready/ # Set up Python 2 virtual environment $ virtualenv --system-site-packages ssenv2 $ . ssenv2/bin/activate $ python setup.py develop $ deactivate # Set up Python 3 virtual environment $ python3 venv --system-site-packages ssenv3 $ . ssenv3/bin/activate $ python setup.py develop
Usage
All commands exit with code 1 if the package does depend on python 2, and 0 if does not. If any unrecoverable error occurs then the exit code is 2.
check-package
This checks if any dependency of a ROS package depends on python2. The command takes a name of a ROS package. The package must exist in a sourced workspace. Use –quiet to suppress warnings and human readable output.
$ py3-ready check-package catkin python-argparse did not resolve to an apt package /opt/ros/melodic/share/catkin depends on python
Passing –dot outputs the dependency graph in DOT format.
$ py3-ready check-package --quiet --dot catkin

By default this looks for dependencies on the debian package named python. Use –target to change this name.
$ py3-ready check-package --target python3 gazebo_ros 2>/dev/null /opt/ros/melodic/share/gazebo_ros depends on python3
check-rosdep
This uses rosdep and apt to check if a rosdep key recursively depends on python 2.
$ py3-ready check-rosdep python-sip rosdep key python-sip depends on python
Passing –dot outputs the dependency graph in DOT format. Use –quiet to suppress warnings and human readable output.

check-apt
This uses apt to check if a debian package recursively depends on python 2.

By default this looks for dependencies on the debian package named python. Use –target to change this name.
