I am using xcore, and trying to create my own validator class.
If there is a problem with the config, I want to display an error message like this:
File name(line number): error message

The File name can be taken from the resource's URI, but I did not find any method that will give me the line number in the file where the resource is configured. How do I get the line number?

hi you have to calculate the line number from the node model. see org.eclipse.xtext.validation.DiagnosticConverterImpl.getLocationData(Diagnostic)

what i dont get is: why dont you simply use xtexts validator infrastructure and let xtext do the job for you

I don't mainly rely on the input from the xtext grammar, I have to do some preprocessing before I can check for the validity, thus, I created my own validator.
Or is it possible to use the xtext validator after doing some preprocessing?
