Hi guys, Gmail Notifr was originally written in RubyCocoa, which runs as a little NSStatusBar app and checks your gmail feeds at specified intervals. I started updating it to MacRuby last month. Most changes were just simply updating method_arg1_arg2 to method(arg1:arg2). Since this app saves account/password in Keychain, I also extracted the keychain access code to a separate project. Still have some difficulties on Security.framework's C methods. I also need to make the growl notification work later. I know many guys are interested in how to make menu bar (NSStatusBar) application so I guess this in progress project might help a little. The project repository is: https://github.com/ashchan/gmail-notifr , and the keychain access wrapper project is here: https://github.com/ashchan/macruby-keychain-wrapper . Regarding the C methods calling, the keychain wrapper has to access this API: SecKeychainItemModifyAttributesAndData It would be really great if anyone knows how to construct SecKeychainAttributeList and other necessary parameters for this API and offers some help. --- James Chen ashchan.com | @ashchan <http://twitter.com/ashchan>
