A library that provides a heuristic type inference algorithm for Jinja2 templates.

>>> from jinja2schema import infer, to_json_schema
>>> s = infer('{{ (x.a.b|first).name }}')
>>> s
{'x': {'a': {'b': [{'name': <scalar>}]}}

>>> s = infer('''
... {% for x in xs %}
...   {{ x }}
... {% endfor %}
''')
>>> s
{'xs': [<scalar>]}
>>> to_json_schema(s)
{
    'type': 'object',
    'required': ['xs'],
    'properties': {
        'xs': {
            'type': 'array'
            'title': 'xs',
            'items': {
                'title': 'x',
                'anyOf': [
                    {'type': 'string'},
                    {'type': 'number'},
                    {'type': 'boolean'},
                    {'type': 'null'}
                ],
            },
        }
    }
}
