As it was the case in ROS 1, ROS 2 nodes allow configuration via command line arguments to a certain degree. I personally prefer to do this in rosh as I find it easier to tab-complete and also read the arg specs. I had considered the suggestion above of passing log-level arguments down to individual nodes. Create package and file Let's create a package for testing in RDS by typing the following command. As an example, to assign a string value foo to a parameter string_param for some_node and a string value bar to that same parameter string_param but for another_node upon running some_ros_executable that contains both, one may execute: Wildcards can be used for node names and namespaces as described in Remapping Names. rosconsole provides eight different types of logging statements, at 5 different verbosity levels, with both printf- and stream-style formatting. As an example, to set a global logging level to DEBUG for some_ros_executable, one may execute: ros2 run some_package some_ros_executable --ros-args --log-level DEBUG Loggers can be set using the --log-level option as well: rosrun allows you to run an executable in an arbitrary package without having to cd (or roscd) there first.

It's a very valuable set of tools that ROS developers use on a daily basis. rosparam enables getting and setting parameter server values from the command-line using YAML-encoded text. Create a project in ROS Development Studio (ROSDS) ROSDS helps you follow our tutorial in a fast pace without dealing without setting up an environment locally. From the last example, it looks like this: Slightly upsetting, from my understanding you cannot pass the Node name making it more elegant: Stop using the same := operator for parameter assignments and name remapping rules and introduce additional operators e.g. As an example, to assign an enclave path /foo/bar one may execute: As is, this enclave assignment applies to each and every Domain Participant that some_ros_executable spawns unless explicitly ignored in code or overridden via security environment variables. The ROS graphical tools often require additional dependencies before they can be used, such as graphviz and Python GTK. Alternatively we could have some special handling for --ros-args in ros2 launch, but that would need to be a more carefully thought out feature, ideally not just passing these args to all node entries in the launch file, but instead having the ability to target it to specific nodes (in the case of dynamically loaded component nodes) and/or executables.

Usage: roscd locationname [/subdir] This config file explicitly sets the logging level to DEBUG for the map_server package. --ros-args applies to ROS 2 nodes only.You may pass it to ros2 run solely because it parses none of it and forwards it all to the underlying process.. Having said that, currently this can be achieved by explicitly declaring a launch argument and then using that argument to set launch_ros.actions.Node . rostopic and rosservice, may also be used to further scope remapping rules. This option takes a single configuration file, whose format depends on the actual external logging library being used. In exchange, it makes argument extraction slightly more difficult as all options must be known ahead of time, whereas --ros-args-based namespacing can achieve the same with a couple rules. The LogLevel specifies the minimum level to log for selected categories. You may pass it to ros2 run solely because it parses none of it and forwards it all to the underlying process.
