Howard Lewis Ship discusses how to add extend class functionality at runtime via meta-programming for Java using Tapestry Plastic.
Jean Baptiste Evain presents the reflection and metaprogramming tools provided by Mono: Mono.Reflection, Mono.Linq.Expressions, and Mono.Cecil.
In this presentation from the JVM Languages Summit 2008, Mads Torgersen discusses LINQ, declarative programming and metaprogramming in C#, examples of LINQ syntax and usage, lazy evaluation of LINQ queries, extension methods, lambda expressions, LINQ-to-SQL, LINQ expressions and metaprogramming, expression trees, how the .Net Dynamic Language Runtime (DLR) works, PLINQ, and the future of the DLR.
Giles Bowkett captures the heart and soul of the RubyFringe conference as he demonstrates his revolutionary Archaeopteryx MIDI generator. He delivers an eloquent, highly politicized call to action in a career-defining presentation that is raucously hilarious yet unnerving in its practicality.
Jay Fields presents his concept of Business Natural Languages (BNL). BNLs are a type of Domain Specific Language, designed to be readable by any subject matter expert, which allows to create maintainable specifications and documentation. The example language is shown using Ruby.
Ever wonder just how Rails declarations such as "has many" and "belongs_to" work? Ever wished you could write your own code that worked the same way? It turns out that this style of programming, often called metaprogramming, is easier than you might think. In this talk we'll see how Ruby's open classes, compile-time execution, and full meta-object model make it easy to write your own extensions.
