----+++ Title:   Concrete Syntax For Objects --- Domain-Specific Language Embedding and Assimilation without Restrictions 

----+++ Note

Martin has talked about this subject before (see ConcreteSyntaxForObjects). This time though, it will be a try-out of his [[http://www.oopsla.org/2004/ShowPage.do?id=Home][OOPSLA]] presentation for next week. The presentation will take about 30 minutes.

----+++ Abstract

Application programmer's interfaces give access to domain knowledge 
encapsulated in class libraries without providing the appropriate 
notation for expressing domain composition. Since object-oriented 
languages are designed for extensibility and reuse, the language 
constructs are often sufficient for expressing domain abstractions at 
the semantic level. However, they do not provide the right abstractions 
at the syntactic level. In this talk we will present [[http://www.stratego-language.org/Stratego/MetaBorg][MetaBorg]], a method 
for providing concrete syntax for domain abstractions to application 
programmers. The method consists of embedding domain-specific languages 
in a general purpose host language and assimilating the embedded domain 
code into the surrounding host code. Instead of extending the 
implementation of the host language, the assimilation phase implements 
domain abstractions in terms of existing APIs leaving the host language 
undisturbed. Indeed, [[http://www.stratego-language.org/Stratego/MetaBorg][MetaBorg]] can be considered a method for promoting 
APIs to the language level. The method is supported by proven and 
available technology, i.e., the syntax definition formalism SDF and the 
program transformation language and toolset Stratego/XT. We illustrate 
the method with applications in three domains: code generation, XML 
generation, and user-interface construction.
