Cement CLI Application Framework v2 Beta

Cement2 is an advanced CLI Application Framework for Python, and a complete rewrite of Cement version 0.x/1.x. Its goal is to introduce a standard, and feature-full platform for both simple and complex command line applications as well as support rapid development needs without sacrificing quality.


Cement2 Core features include (but are not limited to):

  • Core pieces of the framework are customizable via handlers/interfaces
  • Extension handler interface to easily extend framework functionality
  • Config handler supports parsing multiple config files into one config
  • Argument handler parses command line arguments and merges with config
  • Log handler supports console and file logging
  • Plugin handler provides an interface to easily extend your application
  • Hook support adds a bit of magic to apps and also ties into framework
  • Handler system connects implementation classes with Interfaces
  • Output handler interface renders return dictionaries to console
  • Cache handler interface adds caching support for improved performance
  • Core library and extensions have zero external dependencies*
  • Extensions with external dependencies packaged separately
  • Controller handler supports sub-commands, and nested controllers
  • 98% Nose test coverage
  • Extensive Sphinx documentation
  • Tested on Python 2.6, 2.7, 3.1, and 3.2

Available Extensions includes:

  • JSON output handler extension (adds –json option)
  • YAML output handler extension (adds –yaml option)
  • ConfigObj config handler extension replaces ConfigParser
  • Daemon extension handles background processes (adds –daemon option)
  • Genshi output handler extension provides Text Templating
  • Memcached cache handler extension provides easy caching

Note that argparse is required as an external dependency for Python < 2.7 and < 3.2. Some extensions rely on external dependencies.
