Typelets is a Python typing utility module designed to augment some of the types provided in Python and third-party libraries. It was built to help develop Review Board, our premier code review product from Beanbag, and we're making it available for use in other projects.

This includes general Python additions, including:

• typelets.funcs: Typing for general keyword arguments in functions.

• typelets.json: Typing for JSON structures, and for application-defined data that can be serialized to JSON.

• typelets.runtime: Utilities for run-time type checking.

• typelets.symbols: Symbols for marking types as unset/unsettable.

Plus typing useful for Django developers:

• typelets.django.auth: Types for accepting users.

• typelets.django.forms: Types for forms and form fields.

• typelets.django.json: Types for Django's JSON serialization.

• typelets.django.models: Types for working with Django models.

• typelets.django.strings: Types for localized strings.

• typelets.django.urls: Types for URL management.

To install typelets, run:

$ pip install typelets

Typelets follows semantic versioning, meaning no surprises when you upgrade.

See the Typelets documentation for usage.

Typelets is available under the MIT license.

Contributions to Typelets can be made on our Review Board server at https://reviews.reviewboard.org/.
