Linting

Running roslint with catkin

Before merging into the main repository roslint is ran on all merge requests. Unless all errors are resolved the merge request will be rejected. To test if your changes would pass the roslint test locally:

• Add the following lines to your CMakelists.txt:

find_package(catkin REQUIRED COMPONENTS roslint ...)

roslint_python()  # pep8 linting
roslint_cpp()     # ROS wrapper of Google's cpplint

Your package.xml should include roslint as a build dependency:

<build_depend>roslint</build_depend>

• Build target roslint:

  • with catkin_make: catkin_make roslint_<package_name>

  • with catkin_tools: catkin build --no-deps <package_name> --make-args roslint_<package_name>

• If build fail copy and execute the gray line that looks something like the following to see more detailed errors:

cd <package_source_directory>; catkin build --get-env <package_name> | catkin env -si  /usr/bin/make roslint --jobserver-fds=6,7 -j; cd -

Running catkin_lint

You should also make sure that the catkin_lint tests pass; running it from the root of your catkin workspace you can run:

catkin_lint --strict --ignore CRITICAL_VAR_APPEND,LINK_DIRECTORY src/mas_domestic_robotics
