This package provides various tools to supplement packaging Python releases.

The cysignals package provides mechanisms to handle interrupts (and other signals and errors) in Cython code, using two related approaches, for mixed Cython/Python code or external C libraries and pure Cython code, respectively.

This package is a fork from the retry package, but with some of added community-sourced features. It provides an easy to use, but functional decorator for retrying on exceptions.

This package provides a Python library for controlling Linux capabilities and attributes, similar to the prctl syscall.

psutil (Python system and process utilities) is a library for retrieving information on running processes and system utilization (CPU, memory, disks, network) in Python. It is useful mainly for system monitoring, profiling and limiting process resources and management of running processes. It implements many functionalities offered by command line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap.

This package outputs version information for modules loaded in the current session, Python, and the OS.

This package provides a Python library intended to make color math, color scales, and color space conversion easy. It has support for:

1. Color scales

2. Color ranges

3. Color blending

4. Brightening/darkening colors

5. Saturating/desaturating colors

6. Conversion to/from multiple color spaces.

Requests-File is a transport adapter for use with the Requests Python library to allow local file system access via file:// URLs.

This package provides a python module for generating random strings of various types. It could be useful for fuzz testing, generating dummy data, or other applications. It has no dependencies outside the standard library.

This package provides a Python library to perform a 3-way merge between strings, based on diff-match-patch. This library performs merges at a character level, as opposed to most VCS systems, which opt for a line-based approach.

This package provides a fast markdown parser in pure Python.

This plugin enables git-like did-you-mean feature in Click.

Copydetect is a tool to detect likely instances of plagiarism based on the winnowing algorithm. It takes a list of directories as input and generates an HTML report displaying copied slices as output.

The calver package is a setuptools extension for automatically defining your Python package version as a calendar version.

This package provides a python client for the Valkey key-value store, forked from redis-py.

This package provides a library for extracting, transforming and loading tables of data. It can read from and write to databases or files in multiple formats, including:

• python objects

• delimited files

• pickle files

• text/XML/JSON/HTML files

• python I/O streams

• Excel XLS/XLSX files

• HDF5 files

Radon is a Python tool which computes various code metrics. Supported metrics are:

• raw metrics: SLOC, comment lines, blank lines, &c.

• Cyclomatic Complexity (i.e., McCabe’s Complexity)

• Halstead metrics (all of them)

• the Maintainability Index (a Visual Studio metric)

FontTools/TTX is a library to manipulate font files from Python. It supports reading and writing of TrueType/OpenType fonts, reading and writing of AFM files, reading (and partially writing) of PS Type 1 fonts. The package also contains a tool called “TTX” which converts TrueType/OpenType fonts to and from an XML-based format.

This package provides a helper module to develop special remotes for git-annex. AnnexRemote implements the line-based external special remote protocol of git-annex, while leaving the behavior of the remote up to the user.

MessagePack is a fast, compact binary serialization format, suitable for similar data to JSON. This package provides CPython bindings for reading and writing MessagePack data.

This package implements a functionality to deal with RabbitMQ Streams using asyncio.

It is designed and implemented with the following qualities in mind:

• asynchronous Pythonic API with type annotations

• use of AMQP 1.0 message format to enable interoperability between RabbitMQ Stream. clients

• auto reconnection to RabbitMQ broker with lazily created connection objects

Support of many RabbitMQ Streams broker features:

• publishing single messages, or in batches, with confirmation

• subscribing to a stream at a specific point in time, from a specific offset, or using offset reference

• stream message filtering

• writing stream offset reference

• message deduplication

• integration with AMQP 1.0 ecosystem at message format level

Natsort lets you apply natural sorting on lists instead of lexicographical. If you use the built-in sorted method in python on a list such as [a20, a9, a1, a4, a10], it would be returned as [a1, a10, a20, a4, a9]. Natsort provides a function natsorted that identifies numbers and sorts them separately from strings. It can also sort version numbers, real numbers, mixed types and more, and comes with a shell command natsort that exposes this functionality in the command line.

This package provides Python modules that abstract many formats of Debian-related files, such as:

• Debtags information;

• debian/changelog files;

• packages files, pdiffs;

• control files of single or multiple RFC822-style paragraphs---e.g. debian/control, .changes, .dsc;

• Raw .deb and .ar files, with (read-only) access to contained files and meta-information.

swagger_spec_validator provides a library for validating Swagger API specifications.
