Hi all,
I am a beginner in XTEXT so sorry if my question is out of interest but I am really blocked...

I try to compile the grammar (see attached file) that seems correct.

But the workflow process (accessible from 'generate XTEXT artifacts' menu) doesn't stop (no line at the end of the process with the 'done' message).

Could you help me please?
Many thanks. Vincent

can you check something like

UnaryExpression:
(operator='+' operand=UnaryExpression
| operator='-' operand=UnaryExpression
| operator='++' operand=UnaryExpression
| operator='--' operand=UnaryExpression
| UnaryExpressionNotPlusMinus
);

UnaryExpressionNotPlusMinus:
{UnaryExpressionNotPlusMinus}
('~' unaryexpression=UnaryExpression
| primary=Primary);
