Hi, I tried writing some macros to help with my programming but there are some things I don't get. How would I go about writing the following kind of macro?
(outer-macro (inner-macro foo 1 2 3)) The intent is for the inner-macro to generate a form that the outer-macro is able to see and parse. These two macros don't have anything to do with each other, except they happen to clash in this regard, and their use should be orthogonal. As I understand it, expansion goes so that outer-macro is expanded first. And that means it sees the syntax (inner-macro foo 1 2 3) and not the form inner-macro would expand to later. So outer-macro can't see the syntax inner-macro will produce. Unless, I am perhaps able to control the expansion from the outer-macro and have it expand all its contents before going on with its own work. How would I go about with this? I tried simple use of expand-syntax but I run into problems of not being able to see the inner-macro in the environment where outer-macro does the expand. Another meta level I suppose. (errors are along the lines of "expand: unbound identifier in module (in the transformer environment, which does not include the macro definition that is visible to run-time expressions)" and "expand: unbound identifier in module (in phase 1, transformer environment)") I may be doing something foolish This is the first time I am writing a macro that needs to parse something from syntax that happens to have macros in it too. -Markku _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
