Python SDK for reporting exceptions, errors, and log messages to Rollbar.

Capabilities include:

• Sending messages and exceptions with arbitrary context

• Getting back aggregates

• Debugging production issues

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.

Importmagic is a Python library for automatically managing imports by finding unresolved symbols in Python code and their corresponding imports.

This package provides a versatile binary analysis platform with the ability to perform dynamic symbolic execution as well as various static analyses directly on binaries. As such, it can be used for all kinds of reverse engineering, vulnerability discovery, exploit generation, and software testing purposes.

This package provides a parse gdb machine interface output with Python.

Lazy object proxy is an object that wraps a callable but defers the call until the object is actually required, and caches the result of said call.

This Python library implements 3-way merge for text.

setuptools-rust is a plugin for setuptools to build Rust Python extensions implemented with PyO3 or rust-cpython.

The fastbencode Python package implements the bencode serialization format for storing and transmitting loosely structured data, originally used by BitTorrent.

The format can encode four different types of values: byte strings, integers, lists, and dictionaries (associative arrays). It's simple and unaffected by endianness,

This package includes both a pure-Python version and an optional C extension based on Cython. Both provide the same functionality, but the C version has significantly better performance.

This package provides n extension module for Click to register external CLI commands via setuptools entry-points.

This package provides python-vdf, a library for working with Valve's VDF text format.

language_data is a supplement to the langcodes module, for working with standardized codes for human languages. It stores the more bulky and hard-to-index data about languages, particularly what they are named in various languages.

arcp provides functions for creating arcp_ URIs, which can be used for identifying or parsing hypermedia files packaged in an archive or package, like a ZIP file. arcp URIs can be used to consume or reference hypermedia resources bundled inside a file archive or an application package, as well as to resolve URIs for archive resources within a programmatic framework. This URI scheme provides mechanisms to generate a unique base URI to represent the root of the archive, so that relative URI references in a bundled resource can be resolved within the archive without having to extract the archive content on the local file system. An arcp URI can be used for purposes of isolation (e.g. when consuming multiple archives), security constraints (avoiding "climb out" from the archive), or for externally identiyfing sub-resources referenced by hypermedia formats.

This package implements a functionality to cache on disk the result of expensive calculations. It was started as part of Pint, the Python units package.

This package provides an ANSI color text library for Python. It provides automatic coloring for dark or light terminals.
