==================

This is an `OASIS TC Open Repository
<https://www.oasis-open.org/resources/open-repositories/>`__. See the
`Governance <#governance>`__ section for more information.

The STIX generator is a tool for generating random STIX content for prototyping
and testing. It uses a simple, sentence-like syntax for expressing what STIX
content to generate. This tool is provided in two forms: as a Jupyter notebook
and as a commandline tool.

For more information, see `the documentation <https://stix2-generator.readthedocs.io/>`__ on ReadTheDocs.

Jupyter Notebook
----------------

The `Jupyter notebook <https://jupyter.org/>`__ provides an interactive
environment to input generator syntax and view the generated content. To use
the notebook, install the generator's dependencies including the ``jupyter``
extras, and run Jupyter:

.. code-block:: bash

    pip install -e .[jupyter]
    jupyter nbextension install stix2viz --py
    jupyter nbextension enable stix2viz --py
    jupyter notebook

Open ``stix.ipynb`` in Jupyter to use the tool. Look at ``examples.ipynb`` for
documentation and examples of the syntax.

Commandline Tool
----------------

The commandline version of the tool reads prototyping language from a file, and
prints the generated objects to stdout.  If a bundle is selected, the bundle is
printed instead.

.. code-block::

    usage: build_stix.py [-h] [-b] [-e ENCODING] [-v] [--stix-version {2.0,2.1}]
                         [--extra-specs EXTRA_SPECS] [-m]
                         language-file

    Create STIX content from the STIX prototyping language

    positional arguments:
      language-file         The file containing STIX prototyping language

    optional arguments:
      -h, --help            show this help message and exit
      -b, --bundle          Create a bundle
      -e ENCODING, --encoding ENCODING
                            Encoding to use when reading text files, e.g. STIX
                            prototyping language, custom generator specifications,
                            etc. Default=utf-8
      -v, --verbose         Enable verbose diagnostic output. Repeat for increased
                            verbosity.
      --stix-version {2.0,2.1}
                            STIX version to use. Default=2.1
      --extra-specs EXTRA_SPECS
                            A JSON file with extra object generator
                            specifications. These will be merged with the built-in
                            specifications, and made available for use in
                            prototyping language content.
      -m, --minimize-refs   Minimize reference properties in generated objects
                            (*_ref and *_refs).

Caveats
-------

The tool generates random data for all properties, so it may be nonsensical but
will have the correct datatype or structure according to the STIX
specification.

The object generator currently only generates STIX 2.1 objects. The commandline
tool and some APIs will error out if any STIX version other than "2.1" is used.

Governance
----------
