Glue:
print_endline (Ocs_print.string_of_ocs r)
where you need it, eg at the top of:
let ocs2flx sr r =
let sex = Ocs2sex.ocs2sex r in
(*
print_endline "OCS scheme term converted to s-expression:";
Sex_print.sex_print sex;
*)
let fresh = ref 1 in
let env = [] in
let flx = Flx_sex2flx.xstatement_t sr fresh env sex in
(*
print_endline "s-expression converted to Felix statement!";
print_endline (string_of_statement 0 flx);
*)
flx
which is in flx_parser. It's called by:
statement_star:
| statement_star statement
@{
let seq,sr,s = $2 in
(match s with Snull -> $1 | _ ->
let sseq,stmts = $1 in
let s' = ocs2flx sr s in
(max seq sseq, (s' :: stmts))),
[Keep_grammar true; Local_data (dyp.last_local_data)]
}
