Documentation

Documenting source code

Generally, all code should be documented using docstrings in a format suitable for extraction. Docstrings in JavaScript should follow the JSDoc format. For general conventions about docstrings in Python, take a look at PEP 257. As for the docstring format, RST (reStrucuredText) style should be used, like in the following example:

def foo(param_a, param_b=None):
    """Brief description in one line.

    Longer description and additional information, if necessary. Here we could also
    include an example or anything else that RST allows us to do:

    .. code-block:: python3

        # An example on how to call the function.
        foo(1, param_b=2)

    :param param_a: Description of param_a.
    :param param_b: (optional) Very long description of an optional param_b that may
        take up multiple lines.
    :return: Description of return value.
    :raises Exception: If something went wrong.
    """

Building the documentation

The source files of the documentation can be found in docs/source. Generating HTML or other output from those files requires Sphinx, which should be installed already, as well as make. If make is missing, it can be installed using the following command:

sudo apt install make

Afterwards, the documentation can be built using:

make -C docs/ html

The generated documentation can then be found inside the build/html directory:

firefox docs/build/html/index.html
