OK, I've had another look, and I still can't see how to do this, so I would appreciate a hint. I have updated my repo to add a launcher script, but again this only works with files that have a #lang line. As I said before, I have worked out how to parse a file without a #lang line (just pass it to my language's read-syntax), but I can't work out how to turn that into a module and execute it. I guess I need something like dynamic-require that takes a syntax-object and an expander module or #%begin-module macro as arguments? -- https://rrt.sc3d.org -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
