Yet another collection of Python utility functions

Project description

Pyng is a collection of Python utility functions I’ve written over the years, and that I keep wishing were available everywhere. Sadly, in many cases I’ve simply pasted copies of individual functions as needed. But no more!

It’s organized as follows:

  • commands: decorator to automatically build an argparse.ArgumentParser by decorating functions you want to expose as script subcommands

  • dicts: dict subsets, dict searching

  • exc: manipulate exceptions, e.g. reraise, retry

  • genio: generator-based file I/O, loosely related to Java file streams

  • graph: filter DAG represented as dict of (key, otherkeys)

  • iters: generic iterator functionality, akin to itertools

  • out: construct a file-like output object to wrap a specified sink function, with buffer_lines as a useful example and syslogger as a practical use case

  • relwalk: os.walk() filtered to produce pathnames relative to the starting directory

  • replacefile: filter a text file in-place

  • timing: time-related utilities, e.g. duration() to produce a human-friendly description of a specified interval and ProgressTimer to abstract ETA computations

  • tk: Tkinter utilities, e.g. prompt for a single password or construct a prompt dialog from (description, type) tuples

  • toposort: topological sort of DAG represented as dict of (key, otherkeys)

In addition…

  • ProgressBar provides experimental progress-bar support for a long- running console script, from self-overwriting console messages through wxPython, zenity, Tkinter. This is very much a work in progress, though functional subsets have been successfully used.

Please see the individual docstrings for more information.
