    gawk libraries for XML, PostgreSQL,...

    Dynamically loaded extension libraries for GNU AWK

    The gawkextlib project provides several extension libraries for gawk (GNU AWK), as well as libgawkextlib containing some APIs that are useful for building gawk extension libraries. These libraries enable gawk to process XML data, interact with a PostgreSQL database, use the GD graphics library, and perform unlimited precision MPFR calculations. These extensions work with GNU AWK version 4.1.1 or later. We have created a framework for packaging gawk extensions, and we welcome further contributions. Recent additions include haru, redis, and select for I/O multiplexing.

    tqdm

    tqdm

    A Fast, Extensible Progress Bar for Python and CLI

    tqdm is a fast, extensible progress bar for Python and CLI that enables you to see the progress of your loops in a clear and smart way. Simply wrap any iterable with tqdm(iterable), and sit back and watch that progress meter go! tqdm can be wrapped around any iterable, or executed as a module with pipes. Just by inserting tqdm (or python -m tqdm) between pipes will pass through all stdin to stdout while printing progress to stderr. tqdm does not require any dependencies, has a very low overhead and uses smart algorithms to predict the remaining time and skip unnecessary iteration displays. It works on just about any platform, console or in a GUI, as well as IPython/Jupyter notebooks.
