How to use Grammar to Ecore Generator
This article describes the steps involved in the generation of .genmodel, .ecore and Java from a grammar file using Gymnast, Emfatic and Grammar2Ecore frameworks.
Initial conditions
- Eclipse plug-in project with a sample grammar file (in this example, SVG.ast) exists as shown in Figure 1.
- JavaCC or Antlr can be used as Parser Generators.
- srcGymnast (in Figure 1) is the source folder to which Gymnast runtime core plug-in is added manually. Please refer "Bugzilla entry 233805"
 |
- Dependent Plug-ins are added in the MANIFEST.MF file. Hence right clicking on the grammar file shows options like 'Generate .genmodel and Java', 'Generate .genmodel' etc. Refer Figure 2.

Steps for Grammar to Java converstion
This section describes the steps involved in the conversion of grammar file to Java code, along with the generation of .genmodel and .ecore. Pproblems like compilation errors, missing files etc., may occur at some of the steps in the grammar to Java conversion process. These problems are documented in Grmr2JavaReport, along with the possible workarounds/solutions.
Step 1: Generate AST
From the context menu of the grammar file,
