Attribute Redefinitions For Syntax Macros

Stc

----+++ Abstract

In many applications of translations it is desired to return to the
original input, for instance to report errors. More generally, there is
need for
a possibility to change the default behaviour of the translation. In this
talk, a technique is
presented to redefine attributes that are specified in the attribute
grammar of an
abstract data structure at run-time. For the implementation an
aspect-oriented
approach to attibute grammars is required. The obtained attribute
redefinition
technique is combined with a syntax
macro supporting compiler, which translates new concrete syntax to
existing abstract syntax.
