I am working as a Software Engineer at Google. I received a PhD in Computer Science from the Software Composition Group of the University of Bern. I am an active open-source developer.

Projects

I am involved in Seaside, a framework for developing sophisticated web applications in Smalltalk. I maintain the OmniBrowser framework, the Refactoring Engine and various other development tools. Some projects I am the author of are:

  • PetitParser, a dynamic parser framework (also available for Java and Dart).
  • Builder, build and test Smalltalk images from Jenkins.
  • Helvetia, language embedding without breaking tools.
  • Gofer, work with groups of package in Monticello.
  • Magritte, a generic self-described meta-model.
  • Pier, an extensible object-oriented content management system.
  • jQuery and jQueryUI for Seaside, change the way you program Javascript.
  • Scriptaculous, let Seaside applications fly Web 2.0 style.
  • Comet, HTTP server push extension for Seaside.
  • SqueakSource, a Smalltalk source code repository.

    In a previous post I described the basic principles of PetitParser and gave some introductory examples. In this blog post I am going to present a way to define more complicated grammars. We continue where we left off the last time, with the expression grammar. Writing parsers as a script as we did in the previous post can be cumbersome, especially...
