This Python library provides a recursive descent parser with backtracking and memoization (a.k.a. packrat parser). Arpeggio grammars are based on PEG formalism. Arpeggio's main use is a foundation for a toolchain for DSL development but it can be used for all sorts of general purpose parsing.

This package provides facilities for working with VCS repositories in Python.

CppHeaderParser is a pure python module that will parse C++ header files and generate a data structure representing the class .

Cairocffi is a CFFI-based drop-in replacement for Pycairo, a set of Python bindings and object-oriented API for cairo. Cairo is a 2D vector graphics library with support for multiple backends including image buffers, PNG, PostScript, PDF, and SVG file output.

LibCST parses Python source code as a CST tree that keeps all formatting details (comments, whitespaces, parentheses, etc). It's useful for building automated refactoring (codemod) applications and linters. LibCST creates a compromise between an Abstract Syntax Tree (AST) and a traditional Concrete Syntax Tree (CST). By carefully reorganizing and naming node types and fields, LibCST creates a lossless CST that looks and feels like an AST.

Kazoo is a Python client library for the Apache Zookeeper distributed application service. It is designed to be easy to use and to avoid common programming errors.

Dictdiffer is a Python module that helps you to diff and patch dictionaries.

doit is an automation tool that brings the power of build-tools to execute any kind of task.

A task describes some computation to be done (actions), and contains some extra meta-data. The actions can be external programs or Python functions. A single task may define more than one action. doit uses the task’s meta-data to:

• cache task results

• correct execution order

• parallel execution

• powerful dependency system

A pure-python universal errors-and-erasures Reed-Solomon Codec, based on the tutorial at Wikiversity. This is a burst-type implementation, so that it supports any Galois field higher than 2^3, but not binary streams.

This package is a simple RTF tokenizer.

This package contains a small collection of test tool plugins for nose2 and flake8.

A library to identify devices (phones, tablets) and their capabilities by parsing (browser/HTTP) user agent strings.

This package provides handy routines for dealing with text, such as wrapping, substitution, trimming, stripping, prefix and suffix removal, line continuation, indentation, comment processing, identifier processing, values parsing, case insensitive comparison, and more.

PYHDF4 is a python wrapper around the NCSA HDF version 4 library, which implements the SD (Scientific Dataset), VS (Vdata) and V (Vgroup) API’s. NetCDF files can also be read and modified. It is a successor of Python-HDF4 which is a fork of pyhdf.

This package implements a functionality for time taking using context managers.

ipyparallel is a Python package and collection of CLI scripts for controlling clusters for Jupyter. ipyparallel contains the following CLI scripts:

1. ipcluster - start/stop a cluster

2. ipcontroller - start a scheduler

3. ipengine - start an engine

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

The Python FTP server library provides a high-level interface to write efficient, scalable and asynchronous FTP servers with Python. It is the most complete RFC-959 FTP server implementation available for Python, and has the following traits:

• It is lightweight, fast and scalable.

• It uses the sendfile(2) system call for uploads.

• It uses epoll, kqueue and select to handle concurrency asynchronously.

• It supports FTPS (RFC-4217), IPv6 (RFC-2428), Unicode file names (RFC-2640) and MLSD/MLST commands (RFC-3659).

• It has a flexible system of authorizers able to manage both virtual and real users.

Pooch manages your Python library's sample data files: it automatically downloads and stores them in a local directory, with support for versioning and corruption checks.

This package contains codecs for transliterating ISO 10646 texts into best-effort representations using smaller coded character sets (ASCII, ISO 8859, etc.).

NumPy is a large library used everywhere in scientific computing. That's why breaking backwards-compatibility comes at a significant cost and is almost always avoided, even if the API of some methods is arguably lacking. This package provides drop-in wrappers "fixing" those.

This package provides the complete NumPy documentation in the Texinfo, and HTML formats.

This is a package for matrices describing the affine transformation of the plane.

Annoy is a C++ library with Python bindings to search for points in space that are close to a given query point. It also creates large read-only file-based data structures that are mmapped into memory so that many processes may share the same data.
