Description
We have a wide variety of packages and modules in Python that help build commandline tools in different ways. One of the more recent contenders is 'click'. It uses a very intuitive approach to create simple CLIs as well as complex ones. In this talk, I will introduce building CLIs with 'click' and illustrate some of its advantages.
Abstract
As developers, we spend a lot of time trying to automate task that we have to
carry out repeatedly. A likely result is a little (or not so little)
commandline tool that supposedly makes our lives easier.
The Python standard library and as well as the wider community have come up
with a wide range of packages that make it easier and quicker to write a
Python script that can handle arguments and options.
My personal experience is that they are good, but not great...until I came
across `click` a tool written by Armin Ronacher. It's just beautiful to work
with and create simple, yet powerful, commandline tools.
In this talk, I will take a look at the landscape of Python packages that help
building commandline tools such as `argparse` and `docopt`. I will then
introduce `click` and illustrate some of the benefits over its alternatives
before looking at a concrete example to show some of its main features.
