Hi,
I am writing a small parser in ocaml, using ocamlyacc. I need to define 2 start symbols in my file parser.mly, but I don't know how to use them. The name of the 2 start symbols are "main"and "main2". I know how to use one start symbol, as here(taken form "calc.ml"):
let _ =
try
let in_channel = open_in "lines.txt" in
let lexbuf = Lexing.from_channel in_channel in
while true do
let result = HorsParser.main HorsLexer.token lexbuf in
Hors.print_pair_list result;
done
with HorsLexer.Eof ->
exit 0
but I don't know how to call the function "HorsParser.main2".
I want to parse a part of the file "lines.txt" using the rule "main", and then, the other part of the file using "main2". Is this possible?
I tried to call "HorsParser.main2", but I got a "Parsing.parse_error".
Thanks,
Ligia
