       The Ideals project & Using clone detection for aspect mining.

   Time:    10:00
   Venue:   H220 (Nikhef)
   Speaker: Magiel Bruntink and Tom Tourwé
   Title:   The Ideals project & Using clone detection for aspect mining.

   The  Ideals project aims to develop a software desing methodology that
   realizes the structured composition of software from separate modules,
   while  handling  system-wide  interacting aspects of a problem domain.
   The  results  of the project are essential for the engineering of next
   generation  complex  embedded  systems. The anticipated results of the
   Ideals  project  are  new  methods  for  architecting,  analyzing, and
   implementing  systems  according  to  an 'aspect-oriented' philosophy.
   They  lead  to  a  higher  level  of separation of concerns and a more
   modular  implementation  of  systems. The proposed methods include the
   analysis and incremental renovation of existing software systems. ASML
   wafer  scanners  are  taken as a case study and act as drivers for the
   project.

   Clone  Detection:  Code  implementing a cross-cutting concern is often
   spread  over  many different parts of an application. Identifying such
   code  automatically  greatly improves both the maintainability and the
   evolvability  of  the application. First of all, it allows a developer
   to  more  easily find the places in the code that must be changed when
   the  concern  changes, and thus makes such changes less time consuming
   and  less  prone  to errors. Second, it allows a developer to refactor
   the  code,  so  that  it  uses  modern  and  more advanced abstraction
   mechanisms, thereby restoring its modularity.

   In  this  talk,  we  evaluate  the suitability of clone detection as a
   technique  for  the  identification of cross-cutting concerns. To that
   end,  we  manually  identify four specific concerns in an industrial C
   application,  and analyze to what extent clone detection is capable of
   finding  these  concerns.  We consider our results as a stepping stone
   toward an automated ``concern miner'' based on clone detection.

   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:
