Rodin Platform 3.3 Release Notes
What's New in Rodin 3.3?
Rodin 3.3 is mainly a corrective version of the Rodin platform which solves stability and usability issues, especially concerning the Theory plug-in.
Here is a short overview of the newly implemented or fixed features.
Better support for the Theory plug-in
We have vastly improved the support for the Theory plug-in, which will allow to finally have a workable Theory plug-in compatible with Rodin 3.x.
Improved interactive proving
The Generalized Modus Ponens reasoner no longer considers hidden hypotheses. This avoids leading the proof to a dead-end.
The interface to external provers has been improved. Now, most mathematical extensions are translated to the external prover (e.g. as an uninterpreted function). This improves the rate of automated proofs when using theories.
Better proof reuse
When a proof has become uncertain (colored in purple), the Rodin platform tries harder to salvage it by rebuilding a similar sound proof. This is particularly useful when restoring projects proved with an old version of Rodin (typically 2.x).
Partial and total surjection shortcuts
Now, one can use the following shortcuts to enter the symbols for surjections:
- partial surjection: +>> and +->>
- total surjection: ->> and -->>
Rule Details view gets refreshed
In some circumstances, the Rule Details view would not refresh in a timely fashion. One had to select another proof tree node, and then again the first node to trigger a refresh. Now, the view gets refreshed consistently as soon as the proof rule on the selected node changes.
Changes for plug-in developers
Rodin 3.3 is built on top of Eclipse 4.6.2 (Neon), which requires Java 8. This shall not be an issue normally (Java is upward compatible), but can cause some glitch in places where code depends on the order of elements in a HashMap traversal, since the hashing algorithm is different.
AST plug-in
The AST parser now supports infix binary relational predicates specified by the Theory plug-in. This allows to define new predicates looking like a = b.
The ISpecialization class of the Event-B AST has been strengthened to detect more error cases (cases where the specialization would produce ill-typed formulas). It is thus not 100 % compatible with Rodin 3.2. But this should not be an issue in general.
Event-B UI
The Rodin Math font is not loaded anymore during the startup of the Event-B UI plugin (this could cause deadlock). It is now loaded lazily and plug-ins that wish to use this font must call
RodinKeyboardUIPlugin.getDefault().ensureMathFontIsAvailable()
from the UI thread before attempting to load this font.
Rodin Editor
The enabling conditions for Rodin editor actions has changed from
fr.systerel.editor.definition.inRodinEditor
to
fr.systerel.editor.definition.editableStructuralMode
which is more precise (and works around a bug in the previous condition).
Installing
Downloading
Upgrading from a previous version of Rodin 3.x
The recommended way to upgrade is to download the platform afresh. It is possible that one could upgrade using the Eclipse mechanism, but we did not tested it.
Requirements - Compatibility
- Configurations supported (and for which binaries are provided)
- Linux 32-bit
- Linux 64-bit
- Windows 32-bit
- Windows 64-bit
- Mac OS X 64-bit
- You need to have a Java JRE (8 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 64-bit:
- package 'libc6-amd64:i386' must be installed, in particular in order to run external prover binaries
- depending on the distribution, you could instead need these packages: lib32z1 lib32ncurses5 lib32bz2-1.0
- 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.
