I am trying to provide id mapping for our web editor context for things such as detecting whether a region is hoverable or not. From my reading I figured the place to do this was with AntlrTokenToAttributeIdMapper and not HighlightingCalculator. However I have run into multiple issues implementing this. All of my files for this live in my dsl.ide package. First i created this class:

@Singleton
class STAntlrTokenToAttributeIdMapper extends DefaultAntlrTokenToAttributeIdMapper 

 override protected calculateId(String tokenName, int tokenType) 
 println("Calculating id for " + tokenName)
 

Then I bound it in my dslIdeModule:

def Class<? extends DefaultAntlrTokenToAttributeIdMapper> bindDefaultAntlrTokenToAttributeIdMapper() 
 return STAntlrTokenToAttributeIdMapper
 

Upon doing a jettyRun, I got this error on startup:

No implementation for org.eclipse.xtext.parser.antlr.ITokenDefProvider annotated with @com.google.inject.name.Named(value=org.eclipse.xtext.ui.editor.contentassist.antlr.internal.Lexer.HIGHLIGHTING) was bound.
 while locating org.eclipse.xtext.parser.antlr.ITokenDefProvider annotated with @com.google.inject.name.Named(value=org.eclipse.xtext.ui.editor.contentassist.antlr.internal.Lexer.HIGHLIGHTING)
 for parameter 0 at org.eclipse.xtext.ide.editor.model.TokenTypeToStringMapper.setTokenDefProvider(TokenTypeToStringMapper.java:30)
 at org.eclipse.xtext.ide.editor.model.TokenTypeToStringMapper.setTokenDefProvider(TokenTypeToStringMapper.java:30)
 at org.eclipse.xtext.service.MethodBasedModule.configure(MethodBasedModule.java:57)

Following the guidance provided on the xtext forum here. I added this to my runtime module:

def void configureHighlightingTokenDefProvider(Binder binder) 
 binder.bind(ITokenDefProvider).annotatedWith(Names.named("org.eclipse.xtext.ui.editor.contentassist.antlr.internal.Lexer.HIGHLIGHTING")).to(AntlrTokenDefProvider);

This caused my runtime error to go away but I am still never hitting the calculateId method in my token mapper. Am I doing my bindings correctly, using the right class for my purpose, or is there some other configuration I am missing?

EDIT1: It seems like it would be easy enough to do this in my HighlightingCalculator which I am already using to provide syntax highlighting. Would there be any reason not to use it instead of the antlrTokenToAttributeIdMapper?

EDIT2: I made the suggested change for my binding to

def void configureHighlightingTokenDefProvider(Binder binder) 
 binder.bind(ITokenDefProvider).annotatedWith(Names.named(LexerIdeBindings.HIGHLIGHTING)).to(AntlrTokenDefProvider);
 

But I am still not hitting my mapping class

something like

class MyDslIdeModule extends AbstractMyDslIdeModule 

 def Class<? extends DefaultAntlrTokenToAttributeIdMapper>
bindDefaultAntlrTokenToAttributeIdMapper() 
 MyDslAntlrTokenToAttributeIdMapper
 

 def void configureHighlightingTokenDefProvider(Binder binder) 
 binder.bind(ITokenDefProvider).annotatedWith(Names.named(LexerIdeBindings.HIGHLIGHTING)).to(
 AntlrTokenDefProvider);
 

should work
