----------------+++ Building Java Transformations with Stratego/XT

*Monday, October 23rd, from 13:30 to 17:00*

----------------+++ Abstract

This tutorial gives an overview of techniques for program transformation,
illustrated through the [[http://www.stratego-language.org][Stratego/XT]] program transformation
system. We explain the general architecture of transformation
systems, and how Stratego/XT is used to assemble such systems
from components. We introduce a set of ready made components
for Java transformation, and show how to program custom transformation
components using Stratego. In particular, we show how to
express local transformations using rewrite rules and strategies and
how context-sensitive transformations can be expressed easily using
dynamic rewrite rules. All techniques and language features are
illustrated with implementations of transformations on Java programs,
that show how to apply all introduced techniques in practice.

----------------+++ Level: Introductory

----------------+++ Required Knowledge
 
Basic understanding of compilers, parsing and program representation
using abstract syntax trees is an advantage, but we briefly summarize
the basics and ignore the technical details of parsing, since
we focus on application of program transformation to a particular
programming language, i.e. Java, for which all required parsing and
pretty-print support is already available.
