Rob's suggestion of using the export should do what you want:

PolyML.export("noprint-poly", (fn () => (PolyML.print_depth 0; PolyML.Compiler.prompt1 := ""; PolyML.Compiler.prompt2 := ""; PolyML.rootFunction ())) );

Then you can run to make the new ml binary: cc -o empty-top-level-poly noprint-poly.o -lpolymain -lpolyml or if you use a mac: cc -o empty-top-level-poly noprint-poly.o -lpolymain -lpolyml -segprot POLY rwx rwx

And finally you have your version of poly that doesn't output anything by default: ./noprint-poly -q

Having said all that, I don't think this is the way to go about building an http server with poly. Instead you probably want to write your own dedicated protocol for handling IO on a port using sockets.

another question: any way to support the GNU readline library under the SML system for user interaction?
