How is operator precedence implemented in ANTLR? I'm using the XText/Antlr package at the moment. Edit: I did what sepp2k suggested, and operator precedence works now, but stuff like 3 +* also work now. The operators are basically "falling through" the tree. Also, I tried the C grammar on ANTLR's website and the same thing happened in ANTLRworks. Anyone know what the issue is? BinaryExpression: 'or'? AndOp; //or op AndOp: 'and'? ComparisonOp; ComparisonOp: ('>'|'<'|'>='|'<='|'=='|'~=')? ConcatOp; ConcatOp: '..'? AddSubOp; AddSubOp: ('+' | '-')? MultDivOp; MultDivOp: ('*' | '/')? ExpOp; ExpOp: '^'? expr=Expression;
