Hello every one :) I am glad to announce the version 1.0 of Spec which introduce a couple of nice features like: - 10 times faster - better semantic - better layout management You can load it in Pharo 1.4 by executing the following snippet: Gofer new url: 'http://ss3.gemstone.com/ss/Spec'; package: 'ConfigurationOfSpec'; load. (Smalltalk at: #ConfigurationOfSpec) perform: #loadDefault. In Pharo 2.0, Spec version 1.0 will be integrated soon :) In addition, we provide a TechReport about Spec[1] which presents: - an example of how to build a UI using Spec, and how to reuse existing widgets, - the public API of the basic widgets I would like to thank Johan Fabry and Stéphane Ducasse who both really helped me for this release :) Ben [1] http://hal.inria.fr/docs/00/70/80/67/PDF/SpecTechReport.pdf
