I am writing an article on metaprogramming and have several questions on Groovy. I would thank any help with them.
1. Is there any example in which @GroovyASTTransformationClass takes an array with more than one element? Something like this: @Retention(RetentionPolicy.SOURCE) @Target([ElementType.TYPE]) @GroovyASTTransformationClass( [FirstTransformation, SecondTransformation] ) @interface MyAnnot { } I could not find one. If this is possible, I suppose that a single annotation can apply transformations in several compiler phases. 2. Suppose I want to use the annotation WithLogging of http://groovy-lang.org/metaprogramming.html#developing-ast-xforms All I have is the Groovy compiler, a .exe file. What do I do? The general question is: how the Groovy compiler finds a **local** AST transformation class? For global transformation the page above says Compiled classes that implement global transformations are in a JAR added to the classpath of the compiler and contain service locator file META-INF... But for local transformations, there is no such observation.
