Before this change, using define-maybe along define-configuration with the no-serialization syntactic keyword would result in the following warning: warning: possibly unbound variable `VARIABLE-NAME' This change introduces the define-maybe/no-serialization variant that does away with defining a serialization helper procedure, which makes it possible to avoid the above warning. * gnu/services/configuration.scm (define-maybe/no-serialization): New syntax. (define-maybe-helper): New procedure. (define-maybe): Define syntax using the above procedure. * tests/services/configuration.scm (tests): Fix module name. (custom-number-serializer): Do not print to standard output. (maybe-number?, serialize-maybe-number): New procedures defined via the define-maybe macro. (config-with-maybe-number): New configuration. (serialize-number): New procedure. ("maybe value serialization"): New test. (maybe-string?): New procedure defined via the define-maybe/no-serialization macro. (config-with-maybe-string/no-serialization): New configuration. ("maybe value without serialization no procedure bound"): New test. |
