Eclipse version

You need the RCP/Plug-in Developers 3.5 version of Eclipse available at http://www.eclipse.org/downloads/ to run Rascal.

Please note that:

• Rascal really needs the RCP/Plug-in Developers 3.5 version of Eclipse, do not try it with other versions
• Rascal only runs on 32-bit Java with 32-bit Eclipse
• Rascal needs a JDK because it uses the Java compiler, so please download a JDK, not just a JRE.
• For MacOSX, Cocoa version only
• You need to set the stacksize of Eclipse using -vmargs -Xss8m

Required Eclipse plugins

You first need to install the IMP analysis and IMP IDE runtime features from http://download.eclipse.org/technology/imp/updates/:

• Start Eclipse.
• Select Help -> Install New Software.
• Add http://download.eclipse.org/technology/imp/updates/ as software site and be patient since this site may be slow.
• Select the IMP analysis feature and the IMP IDE runtime->IMP runtime plugin (not the whole feature is needed).
• Select Next (several times) and accept the software license.
• Once these plugins have been installed, restart Eclipse.

Installing Rascal

The Eclipse update site for Rascal is: http://www.rascal-mpl.org/updates:

• Repeat the steps given above but now with http://www.rascal-mpl.org/updates as software site.
• Again, be patient since a lot of (meta) data has to be downloaded.

We currently only release alpha versions of Rascal, which are subject to frequent changes.
