Hi,

I am splitting Grammar in two files. Reason is my Grammar is quit large and i ma getting error like "The code for the static initializer is exceeding the 65535 bytes limit".
to resolve that error after searching in forum i found solution, on using
fragment = parser.antlr.XtextAntlrGeneratorFragment2 {
options = {
classSplitting = true
fieldsPerClass = "200"
methodsPerClass = "200"
}
}
in workflow will solve the problem. But after running the workflow i am getting exception like ''java.lang.IllegalStateException: The given EMF object already contains an adapter for CombinedGrammarMarker" .
FYI: I am using eclipse neon and xtext 2.10 .
I am attaching the files which will reproduce the problem.
My exception stacktrace looks like this -
25433 [main] ERROR mf.mwe2.launch.runtime.Mwe2Launcher - Problems running workflow org.xtext.example.mydsl.GenerateMyDsl:

Hi

You seem to be splitting for a reason for which you have already found a workaround, so why bother?

If you want multiple grammars you need multiple everything including multiple MWE2 XtextGenerators. Otherwise as you have observed you get duplication conflicts.

If your grammar has plausible layers, splitting may be a good idea.

QVTrelation.xtext extends QVTbase.xtext extends EssentialOCL.xtext extends Base.xtext, so it can be done, but each layer is treated as a distinct Xtext development with its own model layer and workflow.

Recent Xtext developments with modules may facilitate a vertical rather than horizontal split.

Regards

Ed Willink

Thanks for the quick reply..
Actually here my main concern is to get rid of error "The code for the static initializer is exceeding the 65535 bytes limit".
I checked ,even for single grammar file also and after adding
fragment = parser.antlr.XtextAntlrGeneratorFragment2 {
options = {
classSplitting = true
fieldsPerClass = "200"
methodsPerClass = "200"
}
} in mwe2 file, i am getting exception "java.lang.IllegalStateException: The given EMF object already contains an adapter for CombinedGrammarMarker".

Please test if the problem is still there in Xtext 2.17.1

Hi

I am using Eclipse Neon 3 . Will Neon 3 supports Xtext 2.17.1 ?
I am trying to install Xtext 2.17.1 ,it is showing can not perform operation and details like this--
Cannot complete the install because one or more required items could not be found.

That was not my question
No it's not supported (minimal tp is oxygen)
I want to know if the problem is still there in the latest Xtext

btw

adding XtextAntlrGeneratorFragment2 makes zero sense.
it is already there.

parserGenerator = {
debugGrammar = true
....
}

Did you configure the parser generator with your options as shown above instead
Of adding the fragment a second time

Hi

If you post a repro, we could possibly tell you what you have done wrong, rather than just guessing at possibilities.
