Grandalf is a Python package made for experimentations with graphs drawing algorithms. It is written in pure Python, and currently implements two layouts: the Sugiyama hierarchical layout and the force-driven or energy minimization approach. While not as fast or featured as graphviz or other libraries like OGDF (C++), it provides a way to walk and draw graphs no larger than thousands of nodes, while keeping the source code simple enough to tweak and hack any part of it for experimental purpose. With a total of about 1500 lines of Python, the code involved in drawing the Sugiyama (dot) layout fits in less than 600 lines. The energy minimization approach is comprised of only 250 lines!

Grandalf does only 2 not-so-simple things:

• computing the nodes (x,y) coordinates (based on provided nodes dimensions, and a chosen layout)

• routing the edges with lines or nurbs

It doesn’t depend on any GTK/Qt/whatever graphics toolkit. This means that it will help you find where to draw things like nodes and edges, but it’s up to you to actually draw things with your favorite toolkit.

Retrying is a general-purpose retrying library to simplify the task of adding retry behavior to just about anything.

Features:

• Generic Decorator API.

• Specify stop condition (i.e. limit by number of attempts).

• Specify wait condition (i.e. exponential backoff sleeping between attempts).

• Customize retrying on Exceptions.

• Customize retrying on expected returned result.

This package provides support for the APA style within pybtex.

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

Miniboa is a simple, asynchronous, single-threaded, poll-based Telnet server.

This package provides a library for communicating with the GA4GH Task Execution API.

Python logging made (stupidly) simple

This package provides liblabjackusb, a USB library for low-level communication with the U3, U6, UE9, Digit, T4 and T7 LabJack data acquisition instruments. A udev rule is also included to allow unprivileged users to communicate with the instruments via USB.

This package provides a decorator for adding multiple argument dispatching to functions. The decorator creates a multimethod object as needed and registers the function with its annotations.

This package provides procedures for quickly writing configurable applications and daemons.

PyZMQ is the official Python binding for the ZeroMQ messaging library.

Pyphen is a pure Python module to hyphenate text using existing Hunspell hyphenation dictionaries.

Amply allows you to load and manipulate AMPL/GLPK data as Python data structures.

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 provides tools for computing deep differences and searching of any Python object/data. Recreate objects by adding adding deltas to each other.

autocommand is library to automatically generate and run simple argparse parsers from function signatures.

This package provides a plugin for Setuptools for revision control with Git.

This package provides a build hook plugin for Hatch to automatically bs generate a manual page from an ArgumentParser object, using argparse-manpage by Pavel Raiskup.

This package provides a Python progressbar library to provide visual (yet text based) progress to long running operations.

This package implements a CAN matrix object in Python which describes the CAN-communication and its needed objects such as board units, frames, signals, and values. It also includes two command-line tools (canconvert and cancompare) for converting and comparing CAN databases.

This library helps to redirect sys.stdout to a stream or a file while executing some piece of code, including C code running within a Python process.

This module is a pure Python port of jgm's commonmark.js, a Markdown parser and renderer for the CommonMark specification, using only native modules.

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.

This package provides a UTF-8 compatible encoding future_fstrings, which performs source manipulation. It decodes the source bytes using the UTF-8 encoding and then rewrites Python 3.6 style f strings.
