It works in batch mode, but syntax extensions must be given to camlp4
as cmo or cma files. Find attached your program and its two examples.
First compile your extension by:
      ocamlc -pp camlp4o -I +camlp4 -c my_extension.ml

And your two examples by:
      ocamlc -pp camlp4o -c my_file.ml
      ocamlc -pp camlp4o -c my_file2.ml

You can also pretty print the corresponding pure OCaml code, to see
what the syntax extension did, by:
      camlp4o pr_o.cmo my_file.ml
      camlp4o pr_o.cmo my_file2.ml
