Project description
Demo | Documentation | GitHub | PyPI
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'}
],
},
}
}
}More examples can be found at the demo page.
