Hi! Since Chicken lacks a built-in module system, I'm playing with the syntax-case egg. I want to take an extension (say SRFI-39) and make that (or parts of it) available as a syntax-case module. It seems I have to use EXPORT-TOPLEVEL instead of the export list, since this doesn't work:
(module foo (append!) (require-extension srfi-1)) ===> Error: missing definition for export(s): (append!) This works: (module foo () (require-extension srfi-1) (export-toplevel append!)) So now, the question is what to do about syntax (i.e. macros). The syntax-case egg docs mention that EXPORT-TOPLEVEL doesn't support syntax. So how would I export a macro imported from an extension loaded with REQUIRE-EXTENSION? This doesn't work: (module spells.parameter (parameterize) (require-extension srfi-39) (export-toplevel make-parameter)) ===> Error: missing definition for export(s): (parameterize) Any ideas? Another thing that I noticed when using the syntax-case egg is that INCLUDEs are not relative to the file containing the module declaration, but I think they should be. So given a file "some/dir/modules.scm": (module foo (bar) (include "foo.scm")) Now running "csi -R syntax-case some/dir/modules.scm" should look in "some/dir" for foo.scm instead of the current directory. This is also what happens in mzscheme when using the INCLUDE syntax.
