# Install system dependencies, namely a very barebones ROS setup.
before_install:
  - sudo sh -c "echo \"deb http://packages.ros.org/ros/ubuntu $ROS_CI_DESKTOP main\" > /etc/apt/sources.list.d/ros-latest.list"
  - wget http://packages.ros.org/ros.key -O - | sudo apt-key add -
  - sudo apt-get update -qq
  - sudo apt-get install -y python-catkin-pkg python-rosdep python-wstool ros-$ROS_DISTRO-catkin lcov
  - source /opt/ros/$ROS_DISTRO/setup.bash
  # Prepare rosdep to install dependencies.
  - sudo rosdep init
  - rosdep update
  - pip install --user cpp-coveralls

# Create a catkin workspace with the package under integration.
install:
  - sudo apt-get install -y -qq lcov
  - mkdir -p ~/catkin_ws/src
  - cd ~/catkin_ws/src
  - catkin_init_workspace
  # Create the devel/setup.bash (run catkin_make with an empty workspace) and
  # source it to set the path variables.
  - cd ~/catkin_ws
  - catkin_make
  - source devel/setup.bash
  # Add the package under integration to the workspace using a symlink.
  - cd ~/catkin_ws/src
  - ln -s $CI_SOURCE_PATH .

# Install all dependencies, using wstool first and rosdep second.
# wstool looks for a ROSINSTALL_FILE defined in the environment variables.
before_script:
  # source dependencies: install using wstool.
  - cd ~/catkin_ws/src
  - wstool init
  - if [[ -f $ROSINSTALL_FILE ]] ; then wstool merge $ROSINSTALL_FILE ; fi
  - wstool up
  # package depdencies: install using rosdep.
  - cd ~/catkin_ws
  - rosdep install -y --from-paths src --ignore-src --rosdistro $ROS_DISTRO

# Compile and test (mark the build as failed if any step fails). If the
# CATKIN_OPTIONS file exists, use it as an argument to catkin_make, for example
# to blacklist certain packages.
#
# NOTE on testing: `catkin_make run_tests` will show the output of the tests
# (gtest, nosetest, etc..) but always returns 0 (success) even if a test
# fails. Running `catkin_test_results` aggregates all the results and returns
# non-zero when a test fails (which notifies Travis the build failed).
script:
  - source /opt/ros/$ROS_DISTRO/setup.bash
  - cd ~/catkin_ws
  - catkin_make $( [ -f $CATKIN_OPTIONS ] && cat $CATKIN_OPTIONS )
  # Run the tests, ensuring the path is set correctly.
  - source devel/setup.bash
  - catkin_make run_tests && catkin_test_results

# Generate code coverage, other artifacts
