I just published a new library that automatically creates all implicit conversions and extension functions for the Android SDK.
The gist: It iterates android.jar to find all classes with single-abstract-methods. For each of these methods, an implicit conversion is created for a function to the class type. Once all the conversions have been generated, the android.jar is iterated again to find all usages of these classes. For each of these usages which takes these SAM classes as a single argument, an extension function is generated (by removing any prefixed 'set' and suffixed 'Listener') from the name. Any () => A function becomes => A for by-name usage instead. Implementation: Mostly using asm and a little bit of java reflection where I got stuck, a little bit of canned buggery where I got stuck even more. The technique should be applicable to any other library used on android to generate simple extensions like these. What it looks like: Generated code: https://gist.github.com/pfn/b4dc88b80e846f1fbac1 github: https://github.com/pfn/android-conversions Use it from sbt: libraryDependencies += "com.hanhuy.android" %% "scala-conversions" % "1.0" Hope this helps anyone that's been wanting something like this. -- You received this message because you are subscribed to the Google Groups "scala-on-android" group.
