I meant this relative to the types declarations. I want to exploit this documented behaviour (from "chicken type"): If library code is used with `import` and a `.types` file of the same name exists in the extension repository path, then it is automatically consulted. This allows code using these libraries to take advantage of type-information for library definitions. So, for now I will: generate a ".types" file for each module; concatenate them into a single ".types" file; install the global resulting file along with the shared library. Two questions: 1. Is there a way to print to stderr the list of consulted ".types" files? I do not see such an option in: http://wiki.call-cc.org/man/5/Using%20the%20compiler 2. Let's assume the relevant ".types" files are loaded; with the following pseudo code: is the type specification of "the-func" used by the program? (module (the-sub-module) () (import (scheme) (chicken type)) (: the-func (fixnum -> fixnum)) (define (the-func N) N)) (module (the-module) () (import (only (chicken module) reexport)) (reexport (the-sub-module))) (module (the-program) () (import (the-module)) (the-func 123)) TIA -- Marco Maggi _______________________________________________ Chicken-users mailing list Chicken-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-users
