To build this you need to install

• make
• graphviz

With venv

# activate the venv
python3 -m venv ros2doc

# activate venv
source ros2doc/bin/activate

# install required packages
pip install -r requirements.txt -c constraints.txt

# deactivate the venv
(ros2doc) deactivate

For development we currently use Noble as our build platform. And all python versions are pinned in the constraints file to make sure that things are reproducible. To upgrade the system validate that things are working and then use pip freeze > constraints.txt to lock in the versions to upgrade.

For local testing of the current tree use:

make html

sensible-browser build/html/index.html

To test building the multisite version deployed to the website use:

make multiversion

sensible-browser build/html/rolling/index.html

NB: This will ignore local workspace changes and build from the branches.
