UrlRewriter class

urw.rewrite( from, to , test )

Add a rule to the rewriter. If from is a String, the whole URL is treated as to. If it's a RegExp, URL.replace(from, to) is used instead. test should be a Function which will be called with the current urlRewriter as this and it's expected to return a Boolean indicating whether the current rule should be applied or not.

urw.unrewrite( from )

Undo a previous rewrite call.

urw.compute( url , info )

Transform a URL taking into account previously set rewrite rules. info will be used as the only argument of their test functions.

urw.format( url , query )

Add all query's enumerable properties and its respective values to the query part of provided URL, and set its fragment to fragment, returning the new decoded URL.

urw.take( event [, callback , ...args ] )

An equivalent of:

urw.on(event,function*(e,d){
  yield e.take();
  if(callback) callback(e,d,..args);
});

urw.capture( event [, callback , ...args ] )

An equivalent of:

urw.on(event,function*(e,d){
  yield e.capture();
  if(callback) callback(e,d,..args);
});
