Rodin Platform 2.4 Release Notes

What's New in Rodin 2.4?

From this release on, the Rodin platform is also provided for 64-bit Windows and Linux OSes.

• Modelling

Rodin Editor: the Rodin Editor is now part of the Core Platform as the default editor for machines and contexts. The older structured editor is still there though.

• Building

proper build: the builder now systematically deletes temporary files (*.bcm_tmp and alike); these files were a source of many troubles in further builds

• Proving

Type Environment View: this new view shows the type environment for the current node of the proof (free identifiers and their type). It is accessible through "Window > Show View > Type Environment"

Proof Simplification: once proofs are complete, they can be automatically simplified, by removing unneeded steps (mostly: unused inference by post tactic); this feature is however disabled by default, you can enable it by "Window > Preferences > Event-B > Sequent Prover > Simplify complete proofs when saving"

Auto Tactic: a new tactic combinator 'Attempt after Lasso' is available in Auto Tactic profile editor.

Import/export profiles: from the tactic preference page, profiles can be exported and imported to/from the file system

Preference Scope: the shortcut to Auto Tactic Preference in Proof Control now indicates whether the current project has specific tactic settings or uses the global workspace settings

• Changes for plugin-developers

switch to Eclipse 3.7.1 (no impact expected)

new XProver API: external prover providers can now extend XProverReasoner2 along with the ISimpleSequent framework. ProcessMonitor also provides a wrapCommand method to properly handle external prover process interruption.

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.

Installing

Upgrading from Rodin 2.3.x

Note: if you installed the Rodin Editor in Rodin 2.3, you have to uninstall it before upgrading to Rodin 2.4. The Rodin Editor is now part of Rodin 2.4 and it will be installed during the upgrade.

Use rodin-2.4-repo.zip:

• download archive rodin-2.4-repo.zip
• launch Rodin 2.3.x
• Help > Install New Software... > Add... > enter a name (for instance "Rodin 2.4") then

Archive... > select the rodin-2.4-repo.zip archive

Mac users may have to use Local... then point to archive root directory, in case the archive was automatically unzipped

• set options in the bottom of the page:

• check
  • "Show only the latest versions of available software"
  • "Hide items that are already installed"
• uncheck
  • "Group items by category"
  • "Contact all update sites..."

the central area should now list many entries

• select "Rodin Platform", click "Next"

a message informs "Your original request has been modified. See the details."

"Rodin Platform" is already installed, so an update will be performed instead.

• click Next, accept license, finish and restart

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.
