Hi,
please make sure that the runtime plugin for the definitions language
exports all its packages, esp. the package
org.xtext.example.definitions.services

Sebastian

Hi Sebastian,
When I generate the language code, I receive previously mentioned error for InternalUsagesParser class in org.xtext.example.usages.ui.contentassist.antlr.internal package. The error occures in the grammarAccess.getRuleAAccess() function call of the automatically generated ruleRuleA() function. Interestingly the project works without any problem. I write programs in the editor and I don't take any error, e.g. I can use overriding rule.
Could you possibly introduce me a solution to resolve this error?
Best regards

HI,
sorry i do not get it? i cannot teach you how to write java
import org.eclipse.xtext.GrammarUtil;
import org.eclipse.xtext.IGrammarAccess;
import org.eclipse.xtext.nodemodel.SyntaxErrorMessage;
import org.eclipse.xtext.parser.antlr.SyntaxErrorMessageProvider;
import com.google.inject.Inject;
public class MyDslSyntaxErrorMessageProvider extends SyntaxErrorMessageProvider {
public static final String USED_RESERVED_KEYWORD = "USED_RESERVED_KEYWORD";
@Inject
IGrammarAccess grammarAccess;
@Override
public SyntaxErrorMessage getSyntaxErrorMessage(IParserErrorContext context) {
if (context.getRecognitionException() != null
&& context.getRecognitionException().token != null) {
String unexpectedText = context.getRecognitionException().token
.getText();
if (GrammarUtil.getAllKeywords(grammarAccess.getGrammar())
.contains(unexpectedText)) {
return new SyntaxErrorMessage(
unexpectedText
+ " is a reserved keyword which is not allowed as Identifier",
USED_RESERVED_KEYWORD);
}
}
return super.getSyntaxErrorMessage(context);
}
}

Hi Christian,
My problem is to change default automatic validation error and warning messages and looking for a general solution how to do that.
I've got an example written in xtend-class (see below). I want to extend this code. For different or existing automatic validation error and warning messages I want to add custom messages. For example, I get for Cross-reference an error message ** Couldn't resolve reference to Name 'something' ** which is an automatic validation error, so I want to add or overide with my own code to get my error message something like that ** You cannot call 'something' **. Which functions do I need to realize that and where should I add this to existing keywords. I didn't have found enough sources to get this run, can you give me a hint how to realise it?
package org.xtext.example.mydsl1.ui;
import org.eclipse.xtext.GrammarUtil;
import org.eclipse.xtext.IGrammarAccess;
import org.eclipse.xtext.nodemodel.SyntaxErrorMessage;
import org.eclipse.xtext.parser.antlr.SyntaxErrorMessageProvider;
import com.google.inject.Inject;
public class MyDsl1SyntaxErrorMessageProvider extends SyntaxErrorMessageProvider {
public static final String USED_RESERVED_KEYWORD = "USED_RESERVED_KEYWORD";
@Inject
IGrammarAccess grammarAccess;
/* I want to change Cross Reference Default Error Message:Couldn't resolve reference to Name 'something'... in my own custom message */
@Override
public SyntaxErrorMessage getSyntaxErrorMessage(IParserErrorContext context) {
if (context.getRecognitionException() != null && context.getRecognitionException().token != null) {
String unexpectedText = context.getRecognitionException().token.getText();
if(GrammarUtil.getAllKeywords(grammarAccess.getGrammar()).contains(unexpectedText)) {
return new SyntaxErrorMessage( "is a reserved keyword which is not allowed as Identifier",USED_RESERVED_KEYWORD);//changed Automatic validation (mismatched input //'Hello' expecting RULE_ID)
}
}
return super.getSyntaxErrorMessage(context);
}
}

Could you please let us know how you solved the problem? I'm struggling with the same issue right now.
EDIT: I just figured out the solution. The plug-in of the super language needs to be added to the manifest.mf file of the .ide project of the sub language.
