Subject: PEM - Pieter Olivier -  2.11.00

   Dear colleagues,
   
   I invite you to the PEM talk on next thursday. Pieter Olivier will
   describe his API generation from syntax definitions tools. This is
   joint work with Hayco de Jong.

                   API generation from SDF specifications
                                      
   Date:     2.11.00
   Time:    10:00
   Venue:   M2.79, CWI
   Speaker: Pieter Olivier
   Title:   API generation from SDF specifications

   Tools that operate on terms parsed over some language defined in SDF
   are often quite vulnerable to changes in the SDF definition. We
   propose an API generation mechanism that makes it possible to code
   these tools at a higher level of abstraction: instead of working on
   the concrete syntax represented in AsFix, these API's work more or
   less on the level of the abstract syntax.
   
   In this PEM, we will present in some detail how we transform an
   annotated SDF specification into a full fledged C API that can be used
   both in 'efficient' and 'safe' mode. We will also discuss the
   possibility of generating API's for other languages (Java, Asf+Sdf,
   ...), and we will discuss some issues related to the development of
   the new Meta-environment and related tools.
   
   Groetjes,
   
   Jurgen Vinju

   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:
