IMPORTANT We are currently restructuring the ProB plug-in. After completion we will fix the documentation!

This page describes how to set up a development environment for ProB.

Downloading

Please download a fresh Eclipse Helios (3.6) for RCP Developer. We will assume that you work with a fresh copy of Eclipse in the following description. After downloading unzip it to a folder of your choice (just in case: avoid spaces inside the path).

Setup

Beside the default Eclipse, we require some additional plug-ins for Development:

1. Subclipse 1.6.x
   Install the Subclipse plugin, comprehensive instructions for installations are available from the http://subclipse.tigris.org/servlets/ProjectProcess?pageID=p4wYuA Subclipse Website]. If at some point you receive errors about a missing JavaHL you can switch to the SVNKit Interface in Preferences | Team | SVN or you can install JavaHL (Instructions http://subclipse.tigris.org/wiki/JavaHL). You can also use subversive from the Helios update site (but in this description we will assume you use subclipse).
2. Graphical Editing Framework (GEF)
   GEF can be obtained from the Helios update site. Open the Plugin_installation Facility (Help | Install New Software), select the Helios Update site and search for GEF. You might have to uncheck "Group items by category"
3. Mylyn Connector: Trac (optional)
   If you have read access to the ProB tickets you should install this connector. Like GEF it is available from the Helios update site (search for Trac).
4. Findbugs(optional)
   We strongly recommend to install and use the Findbugs plug-in. Instructions can be found on the Findbugs Website.

Also you can tweak the eclipse.ini file to improve performance. In particular you should increase the size of heap space! You should not use a value greater than your physical memory.

-XX:MaxPermSize=512M
-Xms512m
-Xmx2048m

I use the following additional parameters (no guarantee that they actually help):

-Xss1M
-server
-XX:+DoEscapeAnalysis
-XX:+UseConcMarkSweepGC
-XX:PermSize=256M

Download Rodin Sources

Download the file name rodin.*-dev.zip from the appropriate folder of the[Rodin Sourceforge Site]. Unzip this file to some folder (A good place is a folder named rodin inside your Eclipse installation)

Checkout sources

The sources are available using subversion from https://cobra.cs.uni-duesseldorf.de/prob/trunk/eclipse/

For ProB you need to check out

1. de.prob.core
2. de.prob.plugin
3. de.prob.ui

For BMotionStudio you additionally need de.bmotionstudio.gef.edito and de.prob.animationscript.runtime

Setup target platform

If you have unzipped the rodin dev zip into a folder named rodin inside your Eclipse installation dir you can open the file prob_target.target inside the de.prob.core project and click "Set as Target Platform".

Setup Mylyn

If you have access to the bugtracker tickets you should include them into your Eclipse installation. It is required to install Mylyn Connector Trac from the Helios installation site. Open the Task Repository View and create a new repository using the trac connector. Use http://cobra.cs.uni-duesseldorf.de/trac as the server url. Fill out the wizard as shown in the screenshot and click on validate settings.

Code Formatting

We use "Format on save" using the default Eclipse settings. You can enable it under Window -> Preferences -> Java -> Editor -> Save Actions (on Mac: Eclipse -> Preferences ...):

1. Enable "Perform the selected actions on save"
2. Enable "Format source code"
3. Enable "Organize imports"

The Prolog Sources

If you want to contribute to the Prolog part of ProB, if you want to extend the ProB API, or need them as reference, you need the Prolog sources which can be checked out from https://cobra.cs.uni-duesseldorf.de/prob/trunk/prolog/ using subversion (use, e.g., the command "svn co https://cobra.cs.uni-duesseldorf.de/prob/trunk/prolog/ ProB" to check out the sources). To compile the sources you need a SICStus Prolog licence.
