Doctools

Provides tools to assist with generating documentation for SSVC decision points.

Writes the following files for each decision point: - a json example that can be used in the decision point documentation

Examples

To generate the documentation for the decision points, use the following command:

python -m ssvc.doctools --overwrite --jsondir ./tmp/json_out`

To regenerate the existing docs, use the following command:

python -m ssvc.doctools --overwrite --jsondir data/json

with EnsureDirExists(dir):
    assert os.path.exists(dir)
