A Henshin-Xtext-Adapter

An Xtext adapter for Henshin

The plugins in this repository allow Henshin modules, rules, nodes etc to be referenced directly from any Xtext-based language. To do this, you must:

1. Add uk.ac.kcl.inf.henshinsupport and org.eclipse.emf.henshin.model to the dependencies of your Xtext language plugin (and potentially your test plugin).
2. Add uk.ac.kcl.inf.henshinsupport.ui to the dependencies of your language's .ui plugin.
3. Add referencedResource = "platform:/resource/org.eclipse.emf.henshin.model/model/henshin.genmodel" to the StandardLanguage block in your .mwe2 file.
4. Add import "http://www.eclipse.org/emf/2011/Henshin" as henshin to your .xtext file.
5. Use [henshin::Module] etc in your grammar to reference Henshin meta-classes.

By default, links have no name in Henshin. To allow them to be referenced nonetheless, the plugins generate names following the grammar rule below:

LinkName :
	"[" ID "->" ID ":" ID "]"
;

The first ID is the name of the source node, the second the name of the target node, while the third is the name of the EReference. This naming scheme can be imported into any class in your own code by statically importing uk.ac.kcl.inf.util.henshinsupport.NamingHelper. In an Xtend class, it is recommended to import the class as an extension.
