                           Grammars as Contracts

   Title:   Grammars as Contracts

   Joint work with Merijn de Jonge

   Component-based  development  of  language  tools  stands  in  need of
   meta-tool  support.  This support can be offered by generation of code
   -- libraries or full-fledged components -- from syntax definitions. We
   develop   a   comprehensive   architecture   for   such  syntax-driven
   meta-tooling  in which grammars serve as contracts between components.
   This architecture addresses exchange and processing both of full parse
   trees  and of abstract syntax trees, and it caters for the integration
   of  generated  parse  and pretty-print components with tree processing
   components.

   We  discuss  an  instantiation  of  the  architecture  for  the syntax
   definition   formalism   Sdf,  integrating  both  existing  and  newly
   developed  meta-tools that support Sdf. The ATerm format is adopted as
   exchange   format.  This  instantiation  gives  special  attention  to
   adaptability,  scalability,  reusability,  and  maintainability issues
   surrounding language tool development.

   The  programming environment meetings are a forum for the presentation
   and  discussion  of  new  ideas,  ongoing and finished work. A typical
   meeting  addresses  a subject in the area of programming environments,
   program  generation, algebraic specification, term rewriting, parsing,
   etc.  A presentation ideally takes between 45 and 90 minutes. Meetings
   taking  longer  than 45 minutes are interrupted by a coffeebreak. Most
   Thursdays,  a  meeting is held which starts at 10:00 am. in one of the
   rooms at CWI/WINS. Exceptionally, dates or times may change.

   The    program    of    the    meetings    is    available   on   WWW:
