What's New in Rodin 2.1?

  • General Interface
Improved general platform performance. One of the main task of the scheduled future work, concerning the maintenance and evolution of Rodin, is to increase the platform's performances. Investigation has started and some early enhancements are already part of this release which affect the overall performance of the platform.
See: Rodin Performances
General Platform Performances
New mechanism for automatic tactics preferences. It is now possible to define profiles (e.g. ordered lists) of tactics to be used in post or automatic tactics at both workspace and/or project level. Exported projects contain the profiles defined at project level.
See: How to use it and the page on the work done about Preferences for the automatic tactics
  • Proving
New automatic rewriting rules. Over 150 automatic rewriting rules have been added, making it easier to discharge proof obligations.
See: All_Rewrite_Rules
New proving interface. The proving interface now uses other graphical components to enhance the interactive proving performance and avoid bugs related to large model proving.
Display hypotheses and search for hypotheses is now at least up to 10 times faster!

Rodin Proof Editor Performances

Requirements

  • 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.
  • Configuration
    • Only a 32-bit version of the Rodin platform is provided for PCs
    • Only a 64-bit version of the Rodin platform is provided for MAC

Disclaimer

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.
