Macaroons, like cookies, are a form of bearer credential. Unlike opaque tokens, macaroons embed caveats that define specific authorization requirements for the target service, the service that issued the root macaroon and which is capable of verifying the integrity of macaroons it receives.

Macaroons allow for delegation and attenuation of authorization. They are simple and fast to verify, and decouple authorization policy from the enforcement of that policy.

Redo provides various means to add seamless ability to retry to any Python callable.

Psycopg is a PostgreSQL database adapter for the Python programming language. Its main features are the complete implementation of the Python DB API 2.0 specification and the thread safety (several threads can share the same connection). It was designed for heavily multi-threaded applications that create and destroy lots of cursors and make a large number of concurrent INSERTs or UPDATEs.

Psycopg 2 is mostly implemented in C as a libpq wrapper, resulting in being both efficient and secure. It features client-side and server-side cursors, asynchronous communication and notifications, COPY TO/COPY FROM support. Many Python types are supported out-of-the-box and adapted to matching PostgreSQL data types; adaptation can be extended and customized thanks to a flexible objects adaptation system.

Psycopg 2 is both Unicode and Python 3 friendly.

smartpants can perform the following transformations:

1. Straight quotes ( " and ' ) into "curly" quote HTML entities

2. Backticks-style quotes (``like this'') into "curly" quote HTML entities

3. Dashes (-- and ---) into en- and em-dash entities

4. Three consecutive dots (... or . . .) into an ellipsis entity

Besides being used in web development, CSS is also the way to stylize Qt-based desktop applications. However, Qt's CSS has a few variations that prevent the direct use of SASS compiler.

The purpose of this tool is to fill the gap between SASS and Qt-CSS by handling those variations.

This package provides typing stubs for colorama.

This Python library implements several JSON specs, like JSON Schema, JSON Reference and JSON Pointer.

Jsonschema is an implementation of JSON Schema for Python.

This is a PEP 561 type stub package for the ujson package. It can be used by type-checking tools like mypy, PyCharm, pytype etc. to check code that uses ujson.

immutabledict is an immutable wrapper around dictionaries. It implements the complete mapping interface and can be used as a drop-in replacement for dictionaries where immutability is desired.

This package provides a minimalistic evaluator of Python expression using the ast module.

cattrs is an Python library for structuring and unstructuring data. cattrs works best with attrs classes, dataclasses and the usual Python collections, but other kinds of classes can also be supported by manually registering converters.
