C# 4.0 preprocessor, lexer, and parser in Java

I have built this C# grammar to develop and perform a C# to KDM transformation, see https://github.com/ChristianWulf/CSharpKDMDiscoverer.

  • ANTLR: To compile the grammar files to your favorite language (here: Java)
  • (Optional) Eclipse with ANTLR Plug-In


Do not compile CSharp4Lexer.g because this would result in the error:

error(144): CSharp4Lexer.g:18:9: redefinition of header action

Instead, compile CSharp4PreProcessor.g which triggers the compilation of the CSharp4Lexer.g due to the import.


You also find the following example in the src/example/Main.java file.

String filename = ...
ANTLRFileStream stream = new ANTLRFileStream(filename);
Lexer lexer = new lang.csharp.CSharp4PreProcessorImpl(stream);
CommonTokenStream tokens = new CommonTokenStream(lexer);
CSharp4 parser = new CSharp4(tokens);
