radical.utils 0.7.10

Shared code and tools for various Radical Group (http://radical.rutgers.edu) projects.

This Python package contains shared code and tools for various [Radical Group](http://radical.rutgers.edu) projects. Sometimes we call it the Radical Kitchen Sink.

The radical.utils package contains the following things:

• A [URL class](https://github.com/saga-project/radical.utils/blob/master/radical/utils/url.py) (A SAGA-compliant url parser class)

• A [Plugin manager](https://github.com/saga-project/radical.utils/blob/master/radical/utils/plugin_manager.py) (A simple yet flexible plugin manager and loader)

• A [Config parser](https://github.com/saga-project/radical.utils/tree/master/radical/utils/config) (Config file reader writeer parser)

• A [Logger](https://github.com/saga-project/radical.utils/tree/master/radical/utils/logger) (Support for color log output and tracing)

• An [Object cache](https://github.com/saga-project/radical.utils/blob/master/radical/utils/object_cache.py) (Well, an object cache)

• A [Type checking module](https://github.com/saga-project/radical.utils/blob/master/radical/utils/signatures.py) (Type checking for python call signatures)

• A [Singleton metaclass](https://github.com/saga-project/radical.utils/blob/master/radical/utils/singleton.py) (Implements the Sigleton pattern)

• A [Thread wrapper](https://github.com/saga-project/radical.utils/blob/master/radical/utils/threads.py) (A thin convenience wrapper around threading.Thread)

• A [Call tracer](https://github.com/saga-project/radical.utils/blob/master/radical/utils/tracer.py) (Support for call tracing / debugging)

• A [‘which’ function](https://github.com/saga-project/radical.utils/blob/master/radical/utils/which.py)(Simliar to the ‘which’ command line tool)

The package should in general be compatible with Python 2.6.
