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.
