2023-10-07services: configuration: Use transducers within serialize-configuration....Introduces 'base-transducer', a SRFI-171 based transducer that can be used as a starting point for writing custom configuration record serializing procedures. This also fixes the symbol maybe-value serialization test case. * gnu/services/configuration.scm (empty-serializer?): New predicate. (base-transducer, tfilter-maybe-value): New procedure. (serialize-configuration): Adapt to use base-transducer. * gnu/services/telephony.scm (jami-account->alist): Use transducers to skip fields that are unserializable or whose field maybe-value is unset. * tests/services/configuration.scm: Remove test-expect-fail.

2023-04-02services: configuration: Add user-defined sanitizer support....This changes the 'custom-serializer' field into a generic 'extra-args' field that can be extended to support new literals. Within extra-args, the literals 'sanitizer' and 'serializer' allow for user-defined sanitization and serialization procedures respectively. The 'empty-serializer' was also added as a literal to be used as before. To prevent confusion between the new “explicit” style of specifying a sanitizer, and the old “implicit” style, the latter has been deprecated, and a warning is issued if it is encountered. * gnu/services/configuration.scm (define-configuration-helper): Rename 'custom-serializer' to 'extra-args'. Add support for literals 'sanitizer', 'serializer' and 'empty-serializer'. Rename procedure 'field-sanitizer' to 'default-field-sanitizer' to avoid syntax clash. Only define default field sanitizers if user-defined ones are absent. (normalize-extra-args): New variable. (<configuration-field>)[sanitizer]: New field. * doc/guix.texi (Complex Configurations): Document the newly added literals. * tests/services/configuration.scm: Add tests for the new literals.

(config-with-maybe-symbol): New configuration. ("symbol maybe value serialization, unspecified"): New test. Reported-by: Attila Lendvai <attila@lendvai.name> Maxim Cournoyer
2022-08-01services: configuration: Step back from *unspecified*....Fixes <https://issues.guix.gnu.org/56799>. This partially reverts 8cb1a49a3998c39f315a4199b7d4a121a6d66449. Rationale: *unspecified* cannot be serialized thus used as a G-Expression input, which is problematic/inconvenient when using deeply nested records. As an example, jami-service-type was broken when using partially defined <jami-account> records. * gnu/services/configuration.scm (define-maybe-helper): Check against the 'unset symbol. (normalize-field-type+def): Adjust value to 'unset. (define-configuration-helper): Use 'unset as the default value thunk. * gnu/services/file-sharing.scm (serialize-maybe-string): Check against the 'unset symbol. (serialize-maybe-file-object): Likewise. * gnu/services/messaging.scm (define-all-configurations): Use 'unset as value. (raw-content?): Check against 'unset symbol. (prosody-configuration)[http-max-content-size]: Default to 'unset. [http-external-url]: Likewise. [mod-muc]: Likewise.

2022-06-24services: configuration: Report the location of field type errors....Previously field type errors would be reported in a non-standard way, and without any source location information. This fixes it. * gnu/services/configuration.scm (configuration-field-error): Add a 'loc' parameter and honor it. Use 'formatted-message' instead of plain 'format'. (define-configuration-helper)[field-sanitizer]: New procedure. Use it. Use STEM as the identifier of the syntactic constructor of the record type. Add a 'sanitize' property to each field. Remove now useless STEM macro that would call 'validate-configuration'. * gnu/services/mail.scm (serialize-listener-configuration): Adjust to new 'configuration-field-error' prototype. * tests/services/configuration.scm ("wrong type for a field"): New test. * po/guix/POTFILES.in: Add gnu/services/configuration.scm. Ludovic Courtès
2022-06-15services: configuration: Use *unspecified* instead of 'disabled....Use *unspecified* as a marker for field values that have not been set. Rationale: 'disabled may easily clash with user values for boolean fields, is confusing (i.e. its meaning is *not* boolean false, but unspecified) and it also passes silently through the symbol? predicate of a field of type symbol. * gnu/services/configuration.scm (configuration-missing-default-value): Renamed from configuration-no-default-value. (define-maybe-helper): Use *unspecified* instead of 'disabled, and make the default value optional. * gnu/home/services/desktop.scm (home-redshift-configuration): Change (maybe-xyz 'disabled) to maybe-xyz. * gnu/services/authentication.scm (nslcd-configuration): Likewise. * gnu/services/cgit.scm (repository-cgit-configuration): Likewise. * gnu/services/file-sharing.scm (serialize-maybe-string) (serialize-maybe-file-object): Use 'unspecified?' instead of (eq? val 'disabled). * gnu/services/messaging.scm (raw-content?): Likewise. (ssl-configuration): Change (maybe-xyz 'disabled) to maybe-xyz. (prosody-configuration): Likewise. * gnu/services/file-sharing.scm (transmission-daemon-configuration): Likewise. * gnu/services/messaging.scm (define-all-configurations): Use *unspecified* instead of 'disabled'. * gnu/services/networking.scm (opendht-configuration): Likewise. * gnu/services/pm.scm (tlp-configuration): Likewise. * gnu/services/telephony.scm (jami-account): Likewise.

2022-06-15services: configuration: Support (field1 maybe-number "") format....As opposed to explicitly using 'disabled as value, or using the (field1 (maybe-number) "") format. It's mostly the work of Maxime Devos shared under #54674, with some modifications by Attila Lendvai. * gnu/services/configuration.scm (normalize-field-type+def): New function. (define-configuration-helper) (define-configuration): Support new field format. * tests/services/configuration.scm (config-with-maybe-number->string): New function.

2021-06-29services: configuration: Allow specifying prefix for serializer names....Sometimes two configurations might have the same types for their field values, but the values might be serialized in two completely different ways (e.g. because the two programs have different configuration languages). An example of this would be the ‘serialize-boolean’ procedure in (gnu services mail) and (gnu services getmail). They both serialize a boolean value, but because the Dovecot’s configuration language has a different syntax to the configuration language for Getmail, two different procedures have to be defined. One way to workaround this would be to specify custom serializers for many fields in order to separate the serialization of the values that have the same type but serialize in different ways. This could get very tedious, especially if there are many configurations in the same module. Another way would be to move one of the configurations to its own module, like what was done with (gnu services getmail). However, this would mean that there would be multiple modules containing configurations for related programs, e.g. we have (gnu services mail) and (gnu services getmail), it doesn’t make much sense to keep the Getmail configuration in its own module. This patch will allow one to write something like this: (define-configuration foo-configuration (bar (string "bob") "Option bar.") (prefix bar-)) and the value of the ‘bar’ field would be serialized using a procedure named ‘bar-serialize-string’ instead of just ‘serialize-string’. * gnu/services/configuration.scm (define-maybe-helper): Accept ‘prefix’ argument for using serializer with custom prefix. (define-maybe): Pattern match on ‘prefix’ literal. (define-configuration-helper): Accept ‘prefix’ argument for using serializer with custom prefix. (define-configuration): Pattern match on ‘prefix’ literal. * tests/services/configuration.scm ("serialize-configuration with prefix"): New test.

2021-05-17services: configuration: Add a define-maybe/no-serialization syntax....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. Maxim Cournoyer
