   Dear colleagues,

   The PEM Tomorrow is in F013 at the UvA, not in M280!

                   The Police Files -- JJForester applied

   Date:    24.01.02
   Time:    10:00
   Venue:   F.013 (UVA)
   Speaker: Tobias Kuipers and Joost Visser
   Title:   The Police Files -- JJForester applied

   Part I: Recent developments regarding JJForester

   Since  the  previous  PEM  on  JJForester  (14.12.2000), this tool has
   undergone  many  changes  and has made a new friend: JJTraveler. While
   JJForester  is  responsible for generating Java class hierarchies from
   SDF  grammars,  JJTraveler  supplies  a  library  of  generic  visitor
   combinators   that  can  be  used  to  implement  operations  on  such
   hierarchies.  A  full  update on the features and capabilities of both
   JJs will be presented.

   Part II: Application of JJForester for system analysis

   At  the  Software  Improvement  Group (SIG), JJForester and JJTraveler
   have   been  deployed  for  the  development  of  analysis  tools,  in
   particular  for  the  Dutch  police.  During  this  project, practical
   lessons  have  been  learned  about  applying  GLR parsing and visitor
   combinator  programming  to  program  understanding  problems.  Expect
   creamy  details  on  bug chasing, work-arounds, performance penalties,
   grammar brittleness, and more.

   Finally  we will present a list of discussion points regarding the use
   of "CWI technology" at SIG.

   Have a nice day.

   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:
