ros2cd

ROS2 version of roscd command.

You can use this tool to go to the path where the source code of a ROS2 package is found.

Usage Instructions

Compile de Source Code:

$ gcc -c -Wall -Wshadow ros2ppr.c
$ gcc -o ros2ppr ros2ppr.o

These commands will have created an executable named ros2ppr (ros2 Package Path Resolution).

Move the executable to $PATH

Now, you have to put the executable created previously in one of the paths of the $PATH environment variable. For example: /usr/local/bin/.

Also, you can add a new path to the $PATH.

Source ros2cd.bash

Finally, you have to type source ros2cd.bash.

I recommend to move this file to your home, for example and add the next line to your .bashrc file:

source ros2cd.bash

Once time you have made these steps, you need to configure this tool

Configuration

This tool is prepared for reading its configuration from the next path: $HOME/.ros2cd/paths.txt.

So, you need to create this file. The content of this file must be all paths where you want that ros2cd look for the requested packages (one path per line). This is an example:

/home/user/ros2_ws/src
/home/user/second_ws/src
/opt/ros/foxy/share

That is all you need for using this tool!

Example:

$ ros2cd rviz2
