CHUCK HOUPT It's true that the top layer Cocoa UI is just a WebView, but underneath that is a local copy of the W3C Validator (and supporting libs and modules), running inside a simulated CGI environment. The setup is somewhat like a Dashboard Widget, in that the UI is mostly HTML, with scripts and libraries doing the work. The goal of Validator S.A.C. is to "port" the W3C Validator as cleanly and simply as possible. If you're interested in the details, take a look at the source, which is included with every copy (select Help > Show Source Code). (Version 0.5) |
