Toolsuite for running ROS environments directly from python code, without any specific requirements outside of usual python
Toolsuite for running ROS environments directly from python code, without any specific requirements outside of usual python.
This is a pure python package, to be installed in your system, in order to allow easy ROS access from your python environment.
To install it:
sudo pip install -i https://testpypi.python.org/pypi pyros_setup
To run the self tests, using entry_points defined in setup.py:
OR using the python package directly:
python -m pyros_setup
OR using nosetests specifically:
It can also be used from source inside a catkin workspace in the same way. The workspace act as a virtual environment (using https://github.com/asmodehn/catkin_pure_python). This is useful for development along with ROS packages:
$ catkin_make $ source devel/setup.bash $ python -m pyros_setup $ pyros_setup $ nosetests pyros_setup
However it is also usable by catkin from source for ease of development and compatibility testing.
Basically it allows you to do this:
try: import rospy import roslaunch import rosgraph import rosnode except ImportError: # if ROS environment is not setup, we emulate it. import pyros_setup pyros_setup = pyros_setup.delayed_import_auto(base_path=os.path.join(os.path.dirname(__file__), '..', '..', '..', '..', '..', '..')) import rospy import roslaunch import rosgraph import rosnode
A ROS package WILL NOT be provided, since there is no simple and clean way to turn a pure python package into a catkin package. If you want to depend on pyros-setup, you should use the rosdep pip dependency mechanism.
Note: If you know any easier / less tricky / more pythonic way of handling dynamic imports, let me know!
