Note: this package is under heavy development and breaking changes are to be expected.

Welcome to Thermite, a CLI generator

What are the main things that this package provides.

• run any python function or class that has type annotations
• Use docstrings as the source of help
• not require changing the signature of existing functions to customize
• allow for classes as parameter annotations in functions that will be translated into grouped options
• Allow for custom classes to be used as type annotations.
• provides the possibility to change the defaults in the CLI by using YAML or JSON definitions (an easy way to use configuration files with CLIs)
• provides a plugin-interface to extend functionality (e.g. the help itself is just a plugin)

Installation

The package is available on pip, so can be installed with

pip install thermite

Getting started

For any function, class or instance, just use

from thermite import run
