Sixth Stratego User Days

May 2 - 4, 2005
Utrecht University
Utrecht, The Netherlands

Scope

The Stratego User Days are a yearly meeting of Stratego/XT developers and users. Topics include

• The state of the Stratego language and toolset
  • Ongoing developments
  • Plans and requirements for the future
• Development tools and implementation techniques for transformation systems
  • Compilers, interpreters, documentation generation
  • Transformation components and their composition
  • Deployment issues
  • Benchmarking transformations and transformed programs
  • Extensibility of transformation systems
• Strategies for ...
  • Data-flow optimizations
  • Partial evaluation
  • Typechecking
  • Compilation
  • etc.
• Language-specific transformation systems
  • C, C++, Java, XML, Haskell, Koala, ...
• Methods for design and development of transformation systems
  • Tutorials
  • Experience reports

Format

The meeting has a workshop format with talks, but also plenty of time will be reserved for discussions, code inspections, demonstrations, and time to meet individually. A walk through the woods around the campus is usually part of the deal as well.

Based on experiences from previous years, there are two types of attendees; new Stratego programmers interested in a basic tutorial, and advanced Stratego programmers and researchers interested in the cutting edge. To accomodate both types, the 2006 meeting will consist of a tutorial day and a technical program.

Tutorial

The tutorial day (on Monday) will consist of a basic introduction into Stratego and XT in the morning, and a series of tutorial talks about recent developments in the afternoon. Potential topics include

• Stratego language
  • Rules and strategies
  • Redesigned dynamic rules (including dependent dynamic rules)
• Architecture of transformation systems
  • Language-specific libraries
  • Transformation tool composition

It would be good to know well in advance who will attend the tutorial so that we can adjust the material to the audience.

Technical Program

The other (one or) two days are intended for a technical program consisting of 30 or 45 min talks about topics from the list above or other topics of interest to the Stratego/XT community. These talks will be accompanied by short papers (4 pages), which will be published in a Utrecht University technical report.

Call for Contributions and Participation

We invite everyone interested in program transformation and Stratego/XT to attend the meeting and possibly to make a contribution to the meeting in the form of a talk or demonstration.

Contributions

If you would like to give a talk or demonstration please send a short paper (at most 4 pages) to visser+sud05@cs.uu.nl before March 15 2004, but preferably earlier. If you are in doubt whether a certain topic would be of interest to the meeting, don't hesitate to get in touch via the same email address.

Participation

From Monday, May 2 to Wednesday, May 4, 2005 we meet at Utrecht University so that everyone interested in Stratego/XT can get up to date with current developments, and get an overview of ongoing activities. This is a good opportunity for Master's students to see what is going on in the program transformation project.

A fee to cover the expenses of coffee and lunch may be necessary. Usually we go out for dinner at night, which is at your own expense. Please register as soon as possible, but before April 1, 2005, so that we can make reservations for room, lunch and dinner by sending an email to visser+sud05@cs.uu.nl. If you are coming from outside and need accomodation, you can consult the list of recommended hotels of the department.
