Some time ago I start creating a list of google queries (Bugle) people could use to hunt bugs in source code available in the web. The project started before Google Code Search, so the only way to point to source code was using the Filetype and ? * . operators which worked pretty well. After a couple of months Google announced the Code Search service and the accompanied API which made things much more interesting. Using the new Google service people can supply full regular expression when searching and pinpoint to Bugs a bit more accurately.
Anyway, to cut a long story short, utilising jQuery, Google Code Search API and Bugle, I created an automated version of the Bugle project which looks as close as possible to a desktop based source code review tool.
To demonstrate Bugle Automated I will be looking for bugs in Samba. The first step is to add the package you want to inspect in the Scan field, as you can see below there is Auto Complete functionality available suggesting possible packages while you type a name.
