Software

Tested with Ubuntu 20

Requirements

Use Sourcetrail with ROS

1. Build your workspace with the required cmake flag

Building your workspace with -DCMAKE_EXPORT_COMPILE_COMMANDS=ON which will create a file compile_commands.json in your build/<pkg> directory containing all compiler calls.

colcon build --cmake-args -DCMAKE_EXPORT_COMPILE_COMMANDS=ON

2. Add the project to sourcetrail

See images below

Install requirements

sudo apt-get install python3-pymodbus (maybe python2 also works, but I didn't check)

Run

Server Code

(see modbus_server.py)

Client code

(see modbus_client.py)

Create coverage for pytest using ROS

How is this working with unittests?

	Set options for better exclude by adding a file src/<package_name>/CMakeGraphVizOptions.cmake with
	```
	set(GRAPHVIZ_EXTERNAL_LIBS FALSE)
	set(GRAPHVIZ_IGNORE_TARGETS "gtest;gmock;unittest;integrationtest")
