Hello.

The init method of the SyntacticSequencer class of my language exceeds the 65535 bytes limit and does not compile. The method is short, it contains 63 lines of code. Some of the lines though are exceptionally long.

What approach would you suggest to reduce the size of the method? Perhaps if I split some grammar rules into sub-rules the method might get shorter. I do not understand how the grammar structure relates to the serializer code.

The method creates member objects of type AbstractElementAlias. Some of the members have very lengthy names. One for example is 16400 characters long.

I found the reason why XText produces that huge method. For some grammar rules, I want to parse the source but do not need the result of the rule. I would call the rule from some other one without assigning the result to a variable. And this is why the serializer became huge. For each rule I did not store the result in the produced EMF object, the serializer code would increase. By naming the results, the generated serializer shrinked from 2MB to few KB and it compiles fine.
