Special Grammar not supported
See original GitHub issueThe Special Grammar is not supported. If I try the simple example matcher (m = r.sub.Name in (r.obj.Admins)
), I get an error:
com.googlecode.aviator.exception.ExpressionSyntaxErrorException: Syntax error: unexpect token 'in', maybe forget to insert ';' to complete last expression at 13, lineNumber: 1, token : [type='variable',lexeme='in'],
while parsing expression: `
r_sub.Name in^^^
