Rodin Platform 1.3 Release Notes
From Event-B
What's New in Rodin 1.3?
- General Interface
- Error log view is now available among the other General views. It is accessible through Window > Show view > Error Log and shows the contents of the log file. This provides very useful informations to developers for correcting bugs, and is intended to be copy/pasted by users when posting bug reports.
- Modelling
- Unified creation of new projects and event-B components. Whatever the way a "New" action is triggered ("File > New" in menubar, button in the toolbar, context menu or buttons in the "Event-B Explorer", etc.), the same wizard is used.
- Easier renaming of modelling element labels. The "Rename" menu replaces the "Refactor" menu. Label prefixes can now be customized either globally (workspace scope) or locally (project scope).
- See also: Customize Prefixes
- Building
- Direct children processing only. Project subfolders and their contents are now considered non Rodin contents. As a consequence, models placed in subfolders are not checked for errors and no POs are generated for them.
- Proving
- A new "Replay Proof" command. A new "Proof Replay" command that tries to prove undischarged POs by reusing older proofs of these POs, when they exist. In former releases, it happened that one opened an undischarged PO and it was immediately proved. Then one had to manually go through all undischarged POs, just to see them in turn be proved. The "Proof Replay on Undischarged POs" command does it in a single step. It is accessible by a right-click in the Event-B Explorer.
- See also: Proof Obligation Commands
- The simplification rewrites reasoner version has been incremented. As this reasoner is extensively used by auto provers, many proofs will be marked as broken after cleaning projects, but correct ones will replay successfully.
- NewPP. Changed the name displayed in proofs to "NewPP" to avoid ambiguity with "PP". It used to be displayed as "Predicate Prover".
- Changes for plugin-developers
- Added the origin of predicates in proofs. The origin of a predicate is its corresponding IAxiom, IInvariant, ... It can be fetched by predicate.getSourceLocation().getOrigin() where predicate is a hypothesis or goal of a proof sequent. Note: it works for root sequents only.
- Knowing nature of proof obligations. The nature of a proof obligation (Theorem, Well-Definedness, Invariant Preservation, ...) can be known from a IPOSequent.
- See IPOGNature and IPOSequent#getPOGNature().
- NewPP Plug-in. The newPP tactic has been published. See PPCore#newPP()
- Added ExplorerPlugin#getSelectedStatuses(). Added a function ExplorerPlugin#getSelectedStatuses() to get currently selected POs.
- Extensible pretty print. It is now possible to extend the pretty print page with the same kind of mechanism used to extend the structured editor.
- See also: Extending the Pretty Print Page
Requirements
- It is recommended to run the Rodin platform with a Java 1.5 Runtime Environment.
- Only a 32-bit version of the Rodin platform is provided. Some optional libraries dedicated to 32-bit support may be required in order to run it on a 64-bit OS. Moreover, you will have to install a 32-bit Java Virtual Machine (JVM), and then to set the -vm option to make sure that Rodin is run with the correct JVM.
- eg. /usr/local/rodin/rodin -vm /usr/lib/jvm/ia32-java-1.5.0-sun/bin/java (You have to adjust paths to your system.)

Known Issues
- Early releases of XULRunner 1.9.1 may cause an SWT exception that prevents from opening an editor (as well as any browser-based ui component). More recent releases fix this bug (works fine with xulrunner-1.9.1.7). Alternatively, it is possible to specify XULRunner path to point to 1.9.0: edit "rodin.ini" and add the following line:
-Dorg.eclipse.swt.browser.XULRunnerPath=/usr/lib/xulrunner-1.9.0.14
where "/usr/lib/xulrunner-1.9.0.14" must be replaced with your actual XULRunner 1.9.0 installation directory.
- A warning like the following one is displayed to the standard output when platform starts on GNOME desktop:
(rodin:17254): GLib-WARNING **: g_set_prgname() called multiple times
- It's a GNOME bug, referenced at: [[1]]
- The error log shows the following problem:
org.osgi.framework.BundleException: The bundle could not be resolved. Reason: Missing Constraint: Import-Package: org.eclipse.equinox.internal.util.event; version="1.0.0" at org.eclipse.osgi.framework.internal.core.AbstractBundle.getResolverError(AbstractBundle.java:1313) ...
- It's an Eclipse 3.5 bug. Information found there: [[2]]
