Terminal I/O enables ROS nodes to communicate with external terminal sessions.
Terminal I/O is built using catkin. Type the commands below on a terminal window to create a catkin workspace, clone the repository and build the sources:
$ mkdir -p ~/catkin_ws/src
$ cd ~/catkin_ws/src
$ catkin_init_workspace
$ git clone https://github.com/xperroni/terminal_io.git
$ cd ..
$ catkin_make
First, the terminal_server process must be started in a terminal session, for example:
$ rosrun terminal_io terminal_server
It may also be possible to automatically create a new terminal window and start the server on it as part of a launch file. The details will vary depending on the environment, though; see the project's launch folder for an example on KDE.
Once the server is on, a ROS process can use a terminal_io::Terminal object to communicate to it, printing text or reading back user input. See the include/terminal_io/terminal.h header file for details.
