Add the following to your grammar to override the default insert/delete behavior:
| Code Block |
|---|
@members {
protected Object recoverFromMismatchedToken(IntStream input,
int ttype,
BitSet follow)
throws RecognitionException
{
throw new MismatchedTreeNodeExceptionMismatchedTokenException(ttype, (TreeNodeStream)input);
}
}
|
and now you get
| No Format |
|---|
line 3:714 extraneousmismatched input '3' expecting ';' tree=(FUNC_DEF (FUNC_HDR int foo) (BLOCK (VAR_DEF int i) (= i 3) <mismatched token: [@19,41:41='3',<12>,3:14], resync=i = 3> 3)) |
ANTLR deleted shows the extraneous token. Later, I'll add an automated way to engage this selectively when it's safe to do so (no refs in code/AST stuff): http://www.antlr.org/browse/ANTLR-213mismatched token in the tree now; it didn't recover as it did before.
