Sphinx Extension to add the drawio directive to include draw.io diagrams.

Important: This extension is in development and not all features will work as advertised or at all.

The drawio-desktop package does not run without an x-server (e.g. when in a CI environment), see this issue. The workaround is to install xvfb-run and set the drawio_headless config to True.

1. python3 -m pip install sphinxcontrib-drawio
2. In your sphinx config:

extensions = [
    "sphinxcontrib.drawio"
]

3. Add the binary to $PATH. For Windows add C:\Program Files\draw.io and on Linux add /opt/draw.io/.
4. (required for drawio_headless) sudo apt install xvfb

These are the available options and their default values.

drawio_output_format = "png" # from ["png", "jpg", "svg"]
drawio_binary_path = "/path/to/draw.io-binary"
drawio_headless = False

.. drawio:: example.drawio
    :format: png
    :alt: An Example
    :align: center
    :page-index: 0

If any other of the draw.io CLI tool's options are wanted, please file an issue.
