 Ring logger
This weekend, I had an urge to catch up on one of the umpteen projects that I’d like to start, so I attacked a ring logger.
Basically, a ring logger, keeps the log messages in a ring buffer, which can be dumped when interesting circumstances arrise.
The particularité of this one is that it’s pure javascript, and dumps as a ‘POST’ request to a url. This allows for much improved debugging of js-rich web pages, whilst not filling up the web browsers memory with useless logs.
It depends on ToutouJS but doesn’t have a lot of calls, so it should be easilly portable if anyone finds the need.
 Usage
First off, you have to include the relevent files:
Then you just log away (the mores the better):
js.ring_log.log(js.ring_log.DEBUG,'Test','Test message');
Finally, to retrieve your log, ie dump the buffer:
js.ring_log.dump();
Et voila!
For testing purposes, the logger is pre-configured to call a script log.php in the same directory as it is in, and has a buffer size of 10, both parameters changeable in the source. The different parts of the log messages are seperated by a ‘splitter’, by default ‘==|==’, this is also configurable.
js.ring_log.requestUri='log.php'; js.ring_log.log_data_size=10; js.ring_log.splitter='==|==';
And that’s just about it, hope you find it usefull 
Update: forgot to add the .tgz, oups :$
