Assuming a simple Camlp4 parser that uses a ocamllex lexer wrapped in
a stream,
let rec parse_primary = parser
| [< 'INT n >] -> Int n
| [< 'FLOAT n >] -> Float n
| [< 'STRING n >] -> Str n
| [< 'TRUE >] -> Bool true
| [< 'FALSE >] -> Bool false
| [< >] -> raise (Stream.Error "unknown token when expecting an
expression.")
How do I report the error location?
Do I need to pass loc in with every token?
Then what happens in the error case where there's no token available?
Thanks, Joel
