<div dir="ltr"><div>There are a lot of details to get right in processing a module. To really get them all right, use get-module-code from syntax/modcode. Here's an example that produces expanded syntax rather than a compiled bytecode expression, if that's what you want: #lang racket (require racket/runtime-path syntax/modcode) (define-runtime-path code "code.rkt") (syntax->datum (get-module-code code #:compile expand)) </div>Put your file to expand in "code.rkt" in the same directory as that program. Obviously you can change the code to produce some other path instead, as needed, but define-runtime-path worked for a quick example. <div> </div></div><div class="gmail_extra"> <div>Carl Eastlund</div> <div class="gmail_quote">On Fri, Jun 14, 2013 at 4:32 PM, Vincent St-Amour <<a href="mailto:stamourv@ccs.neu.edu" target="_blank">stamourv@ccs.neu.edu</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Ah, right, sorry about that.
