The CodeThis user script runs on all pages. It is very long, but it breaks down into six sections: - Utility functions
I hate that JavaScript strings don't have a startswith method. I hate that arrays don't have a contains method. Too many years programming in Python have spoiled me. The first few functions are just utility functions that make JavaScript behave the way I want it to, so I can spend the rest of the script writing code that comes naturally. - Feed parser
The PoorMansFeedParser is a quick-and-dirty parser for RSS and Atom feeds. Magic Line autodiscovers the feed for the current page by looking for specially marked <link> elements, and parses all the titles, links, and descriptions from the feed. This means I can find a page later that I never even visited. All I need to do is browse the front page of a weblog, and all the recent articles are added to my personal data store. (Magic Line caches feeds for 24 hours to avoid pummeling the server with every page view.) - FOAF parser
The FOAF RDF vocabulary is like a machine-readable about page. People can publish their name, biography, projects, and other personal information in a standard format that is easily parseable. The PoorMansFOAFParser mines FOAF files for metadata. This means I can find someone by name, even if I forget the URL. FOAF files are also autodiscoverable, with <link> elements in the <head> of the web page. - Parsing other page metadata
Author and keyword information can be hidden in <meta> elements. Tags and category keywords can be marked with <a rel="tag">. Links to friends can be marked with <a rel="friend"> (and lots of other variations). And of course there's always the page title, the page URL, and the referring page URL. - User interface
The Magic Line user interface (magicShow, magicHide, magicKeypress, magicSubmit, magicScrollResults, and magicHideResults) literally takes over the entire browser window and sets up a simple form for finding any page, based on any scrap of information we were able to discover. - Autocompletion
The magicSearch function does the actual autocompletion matching, searching through all the metadata in our private data store and prioritizing the best matches. Page URLs take precedence over other types of metadata, followed by page titles, people's names, article descriptions, tags and keywords, and referrer URLs.
