[antlr-interest] Generate AST from C runtime

[Sergiy Dubovik]

Hei,

Could someone help me to generate AST from a grammar using C with a minimum
amount of C code?
I just want to get a pointer to an AST root. I don't need tree walker. I
have a grammar which generates nice AST in AntlrWorks.
Can I have the same from C? Isn't it so that Antlr generates AST if I
specify options=AST;?


pANTLR3_UINT8 fileName = (pANTLR3_UINT8) "example.rpp";

    pANTLR3_INPUT_STREAM input = antlr3FileStreamNew(fileName, ANTLR3_ENC_8BIT);

    pRppLexer lexer = RppLexerNew(input);

    pANTLR3_COMMON_TOKEN_STREAM tokenStream =
antlr3CommonTokenStreamSourceNew(ANTLR3_SIZE_HINT,
TOKENSOURCE(lexer));

    pRppParser parser = RppParserNew(tokenStream);

     RppParser_prog_return prog;

    prog = parser->prog(parser);
