Bug 350776

Description Karsten Thoms 2011-06-30 03:56:02 EDT

In the generated formatter the following code is produced:
-----------------------------------------------------------------
// It's usually a good idea to activate the following three statements.
// They will add and preserve newlines around comments
//		c.setLinewrap(0, 1, 2).before(getGrammarAccess().getSL_COMMENTRule());
//		c.setLinewrap(0, 1, 2).before(getGrammarAccess().getML_COMMENTRule());
//		c.setLinewrap(0, 1, 1).after(getGrammarAccess().getML_COMMENTRule());
-----------------------------------------------------------------


Uncommenting these lines leads to uncompilable code, since getSL_CommentRule() is not defined for IGrammarAccess.

I propose to change the generator to inject the DSL's GrammarAccess and use this one.

-----------------------------------------------------------------
import com.google.inject.Inject;
import ....services.MyDslGrammarAccess;

public class MyDslFormatter extends AbstractDeclarativeFormatter {
	@Inject
	private MyDslGrammarAccess grammarAccess; 

	@Override
	protected void configureFormatting(FormattingConfig c) {
// It's usually a good idea to activate the following three statements.
// They will add and preserve newlines around comments
//		c.setLinewrap(0, 1, 2).before(grammarAccess.getSL_COMMENTRule());
//		c.setLinewrap(0, 1, 2).before(grammarAccess.getML_COMMENTRule());
//		c.setLinewrap(0, 1, 1).after(grammarAccess.getML_COMMENTRule());
	}
}
