The Developer Support provides resources for developing plug-ins for the Rodin Platform.

Rodin Platform Overview

Getting Started

Architecture of the Rodin Platform

Rodin Platform Core

Event-B User Interface

The Event-B User Interface of the Roding Platform has two major components that are concerned with either modelling in Event-B or proving properties of models.

Apart from these are more minor components.

Event-B Component Library

Event-B models and all proof-related information are stored in the Rodin database. The syntax of the mathematical notation, that is, expressions, predicates, and assignments, are maintained in an abstract syntax tree. Abstract syntax trees are manipulated by means of a class library that can be used independently of Eclipse. They are saved in the database in human-readable form as Unicode character strings. Event-B constructs, such as contexts and machines, are not represented as abstract syntax trees. They are stored and retrieved directly from the database (by contrast, mathematical formulas need additional parsing). Well-formedness of Event-B constructs is verified by a static checker. The static checker has two main purposes: (1) it generates error messages for ill-formed constructs, and (2) it filters well-formed parts of components to be subjected to proof obligation generation. The proof obligation generator uses those parts of constructs that are well-formed and generates proof obligations from them. Finally, the proof manager attempts to prove proof obligations and maintains existing proofs associated with proof obligations. The proof manager works automatically and interactively. When new proof obligations have been generated it attempts to discharge them automatically. If it does not succeed, it permits interactive proof (by means of the proving user interface).

Extending Rodin

Useful Hints

Version Control

All sources of the core Rodin platform (and of some plug-ins) are managed under version control in SourceForge. The repository currently used is Subversion and can be accessed using URL https://rodin-b-sharp.svn.sourceforge.net/svnroot/rodin-b-sharp.




A Plug-in developed for the Rodin Platform will normally consist of a collection of eclipse 'plugin' projects and a single eclipse 'feature' project. The feature project contains branding information such as logo's icons and licensing details. It is also used to identify your Plug-in so that users can install it. To build your Plug-in use an eclipse 'site' project. This will build the jar files for your plugin projects and a jar for your feature. See eclipse documentation for more details.

Now you need to make your Plug-in available for users to install via the Main Rodin Update site (which comes built-in to the Rodin platform).

First upload your jar files onto the Sourceforge uploads area and then create a new release in the FRS (Admin-file releases). Note that you should include a zip of the complete source projects to comply with Sourceforge rules. You must not repeat files that have not changed. Sourceforge does not allow you to upload multiple copies of the same jar file. The Feature jar will take care of unchanged plugin jars and use the existing links. Only new jars should be included in a particular release. See here for details:- http://alexandria.wiki.sourceforge.net/File+Release+System+-+Offering+Files+for+Download

Finally, the update site must be updated to redirect the update requests to the files on the FRS. (Currently this is done by Colin Snook on request - see Rodin developers page for contact details).
