Code Generation on the JVM: Writing Code that Writes Code

“The Pragmatic Programmer” admonished us all to “write code that writes code”: use code generators to increase productivity and avoid duplication. Today's language communities have clearly caught on, as more and more frameworks generate code at compile or runtime. This session covers Project Lombok, Cofoja, Spring Roo, GContracts, Groovy++, and more. We'll reviews the different approaches, including examples of how and why we'd want to do this. Come see how these frameworks are using things like Java and Groovy AST Transformations, AspectJ intertype definitions, and ASM bytecode generators. You'll get an in-depth look at language tools and production deployed AST Transforms and code generators. Audience: developers searching for cutting edge solutions to increasing team velocity.
