hcs-utils 1.3rc2

My personal library collecting some useful snippets.

About

This is my personal collection of snippets that I use in multiple projects. Each one feels a bit to small to merit it’s own library.

So what does it include?

• memoize decorator (caching)

• a storage class wrapping a dict.

• unittest assert functions.

• Functions for handling large JSON documents.

• list_dir(path) –> (dirnames, filenames)

• PID file locking

• A synchronization decorator
