What's New in Rodin 2.6?

  • General changes
    • The Rodin Editor that is part of the Rodin core platform since version 2.4 has been improved for a better modelling experience.
      Please look at its dedicated wiki page and its user guide.
    • Bug fixes and code consolidation.
  • Changes for plugin-developers
    • Formula specialization The AST now supports formula, type, and type environment specialization.
      The Specialisation object is to be retrieved from FormulaFactory#makeSpecialization() and then completed. See org.eventb.core.ast.ISpecialization for more details.
      Specialization is a good choice for the developer who wants to get a copy of a formula where given types and even free identifiers have been replaced (e.g. "instantiated").

Requirements - Compatibility

  • Configurations supported (and for which binaries are provided)
    • Linux 32-bit
    • Linux 64-bit
    • Windows 32-bit
    • Windows 64-bit
    • Mac 64-bit
  • You need to have a Java JRE (6.0 or later) installed on your computer. The Rodin product will not work with a previous version. To run Rodin 64-bit, you need a 64-bit JRE.
  • To enhance your proving experience, the eclipse font settings (size, aspect...) are available from the preferences (General > Appearance > Colors and Fonts > Rodin). These settings allow you to modify the properties set on the Event-B Keyboard Text Font which is used in many views of the Proving UI. However, to enjoy these functionnalities, you need to install the Brave Sans Mono font on your system. You can download this font from the link here.
  • Linux: the internal browser does not work with xulrunner-2.0 (for instance, it causes the welcome page to display a link instead of a html page and the Pretty Printer does not work); xulrunner-1.9.x must be installed.
  • Linux 64-bit:
package ia32-libs (and its dependencies) must be installed.
  • Windows 64-bit:
Atelier B provers work more slowly; it can cause ML to not automatically discharge some sequents that it discharges on windows 32-bit, due to its timeout. A workaround is to download a custom profile: DefaultAuto_ML800, then Window > Preferences > Event-B > Sequent Prover > Auto/Post Tactic > Profiles (tab) > Import..., point to the downloaded file, 'Select All' profiles (there are 2), OK. Then in 'Auto/Post Tactic' tab, select 'Default Auto Tactic Profile (ML 800)' profile for auto-tactics. It is the same as the 'Default Auto Tactic Profile', except ML has a longer timeout (800 ms). You can of course change this timeout by editing the 'ML (800)' profile.
We have not noticed this problem for Linux 64-bit, nor for other platforms; however if you do, the same workaround applies.

Since Rodin is continuously maintained, several unsoundness bugs which have been encountered were investigated and fixed. However, despite the total commitment of our teams to insure the soundness of the platform, some unexpected and unknown soundness issues could remain. We would be grateful if you would report these issues to the development mailing list.
