Hi,

I would like to use the antlrParam flag in an MWE2 file to pass the "-Xconversiontimeout" parameter to ANTLR during compilation, as described here as an example: 20000frames.blogspot.com/2010/09/dealing-with-could-not-even-do-k1-for.html

I am currently using the org.eclipse.xtext.generator.parser.antlr.ex.rt.AntlrGeneratorFragment fragment, which does not accept this parameter.

Is this feature still available in Xtext2, perhaps using another fragment? I tried org.eclipse.xtext.generator.parser.antlr.XtextAntlrGeneratorFragment, which accepted
antlrParam = "-Xconversiontimeout" antlrParam = "30000" but did not seem to take it into account: "reason: timed out (>1000ms)"

On a related note: what is the difference between org.eclipse.xtext.generator.parser.antlr.ex.rt.AntlrGeneratorFragment and org.eclipse.xtext.generator.parser.antlr.XtextAntlrGeneratorFragment?

Regards.

Actually, by using the proper syntax, org.eclipse.xtext.generator.parser.antlr.ex.rt.AntlrGeneratorFragment accepts the option:

fragment = org.eclipse.xtext.generator.parser.antlr.ex.rt.AntlrGeneratorFragment {
	antlrParam = "-Xconversiontimeout" antlrParam = "10000"
	options = {
		classSplitting=true
		...

Sorry for the noise.

Still, my PS stands: what is the difference between org.eclipse.xtext.generator.parser.antlr.ex.rt.AntlrGeneratorFragment and org.eclipse.xtext.generator.parser.antlr.XtextAntlrGeneratorFragment?

Regards.
