Doctools

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

Writes the following files for each decision point: - a markdown table that can be used in the decision point documentation - a json example that can be used in the decision point documentation - a markdown file that builds an insert using mkdocs tabs to switch between the markdown description and the json example

Examples

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

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

To regenerate the existing docs, use the following command:

python -m ssvc.doctools --overwrite --outdir docs/_generated/decision_points --jsondir data/json/decision_points

EnsureDirExists

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