destination 1.3.0

Installation

$ pip install -U destination

Thread Safety

Currently, destination is not thread safe. Hence, you should deepcopy instances or add a mutex lock before using dispatchers and rules in the other threads.

Usage

The default implementation of url parsing uses regular expressions. This is similar to Django and Tornado. You can create rules and dispatchers to resolve and parse your url using regular expressions set in the rules.

Generally, you should start with ReRule and Dispatcher. You can create a ReRule with the regular expression that is going to be used to parse (and possibly compose) the url, and an optional identifier to help you identify which rule is parsed, if an identifier is not provided or its value is set to None, the rule itself will be used as an identifier. A Dispatcher may be instantiated with no arguments as a storage of multiple rules. You can add or remove rules at any time.

ReSubDispatcher is a sub-dispatcher that can be added to a dispatcher as a rule. It uses regular expressions to chop off the part matched to the regular expression and dispatches the rest part to the rules added to it.

BaseRule and BaseDispatcher can be used to create custom rules and dispatchers.
