This package provides a hatch plugin for fetching a version from a package.json file.

This package provides a port of node.js's EventEmitter to python. Additionally, it includes a number of subclasses useful for implementing async and threaded programming in python, such as async/await.

Logfury is a tool for python library maintainers. It allows for responsible, low-boilerplate logging of method calls.

The stack_data Python library extracts data from stack frames and tracebacks. Is can be used to display more useful tracebacks than the default.

This package implements a Python port of the JavaScript mdurl.

This package implements a preferred system exit codes as defined by sysexits.h. This library is inspired by Rust's exitcode.

Python library for TLV encoding and decoding. Represents type and length by one byte each, hence the name tlv8.

This package provides helper functions for injecting a conda environment into the current python environment (by modifying sys.path, without actually changing the current python environment).

Cyclopts is a modern, easy-to-use command-line interface (CLI) framework that aims to provide an intuitive & efficient developer experience.

This package provides a pure-python port of J. Helly's read_eagle.

Factory_boy is a fixtures replacement based on thoughtbot’s factory_girl. As a fixtures replacement tool, it aims to replace static, hard to maintain fixtures with easy-to-use factories for complex object. Instead of building an exhaustive test setup with every possible combination of corner cases, factory_boy allows you to use objects customized for the current test, while only declaring the test-specific fields.

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 a quick single file library for easily adding evaluatable expressions into python projects. Say you want to allow a user to set an alarm volume, which could depend on the time of day, alarm level, how many previous alarms had gone off, and if there is music playing at the time.

Markupsafe provides an XML/HTML/XHTML markup safe string implementation for Python.

This package provides an implementation of chunked, compressed, N-dimensional arrays for Python.

Astor is designed to allow easy manipulation of Python source via the Abstract Syntax Tree.

Prompt-Toolkit is a library for building interactive command line interfaces in Python. It's like GNU Readline but it also features syntax highlighting while typing, out-of-the-box multi-line input editing, advanced code completion, incremental search, support for Chinese double-width characters, mouse support, and auto suggestions.

CairoSVG is a SVG converter based on Cairo. It can export SVG files to PDF, PostScript and PNG files. The main part of CairoSVG is a SVG parser, trying to follow the SVG 1.1 recommendation from the W3C. Once parsed, the result is drawn to a Cairo surface that can be exported to qvarious formats: PDF, PostScript, PNG and even SVG.

This package is a port of Python's built-in functools.lru_cache function for asyncio. To better handle async behaviour, it also ensures multiple concurrent calls will only result in 1 call to the wrapped function, with all awaits receiving the result of that call when it completes.
