I know these were working at some point in the recent past, but I just
rebuilt the grammar and found they don't compile.
The following causes 2 compile errors:
rule_name
scope
{
//int _is_float;
// index of the first token that is not part of this seq
// note that this means you need a >= instead of > in the
CanMatch____ semantic predicates'
// check for whether a token can belong in this sequence.
int _last_specifier;
}
@init
{
$rule_name::_last_specifier = -1;
}
Here are the two errors:
1. The grammar itself won't compile; the antlr tool returns
error 141: unknown dynamically-scoped attribute for scope rule_name:
_last_specifier
2. If you move int _last_specifier; above the line starting with
// index, then the grammar compiles, but you find the following line in
the generated code, causing it to not compile:
protected internal //int _is_float;
