records: Support custom 'this' identifiers.

2019-03-30T10:08:39Z

This lets record users choose an identifier other than 'this-record'. * guix/records.scm (make-syntactic-constructor): Add #:this-identifier. [wrap-field-value]: Honor it. (define-record-type*): Add form with extra THIS-IDENTIFIER and honor it. * tests/records.scm ("define-record-type* & thunked & inherit & custom this"): New test.

records: Allow thunked fields to refer to 'this-record'.

2019-03-25T22:37:06Z

* guix/records.scm (this-record): New syntax parameter. (make-syntactic-constructor)[wrap-field-value]: When F is thunked, return a one-argument lambda instead of a thunk, and parameterize THIS-RECORD. (define-record-type*)[thunked-field-accessor-definition]: Pass X to (real-get X). * tests/records.scm ("define-record-type* & thunked & this-record") ("define-record-type* & thunked & default & this-record") ("define-record-type* & thunked & inherit & this-record"): New tests.

records: Make 'report-duplicate-field-specifier' available at expansion-time.

Fixes a regression in 'guix pack -R' introduced with commit c2dcff41c2e47f5f978f467864d5ed7829939884. The imported modules of 'c-compiler' would be compiled in this order: first (guix records), then (guix search-paths). Consequently, 'report-duplicate-field-specifier' would be reported as unbound while compiling (guix search-paths), leading to a build failure. * guix/records.scm (report-invalid-field-specifier) (report-duplicate-field-specifier): Move within 'eval-expand'.

records: Detect duplicate field initializers.

2019-01-22T22:04:05Z

* guix/records.scm (report-duplicate-field-specifier): New procedure. (make-syntactic-constructor): Call it. * tests/records.scm ("define-record-type* & duplicate initializers"): New test. Co-authored-by: Mark H Weaver

records: Adjust to test changes in 'record-abi-mismatch-error'.

2018-08-31T15:26:56Z

Fixes a test failure introduced in de5cbd4a38a33e0412f1c481fe8e01a871dc13e5. * guix/records.scm (abi-check): Refer to TYPE in an unquoted context so we get at the RTD. * tests/records.scm ("ABI checks"): Adjust 'catch' handler to changes in the 'record-abi-mismatch-error' arguments.

records: Adjust 'record-abi-mismatch-error' arguments.

2018-08-29T21:32:01Z

Previously, 'display-error' (as used by 'warn-about-load-error', for instance) would be called with a wrong number of arguments when a 'record-abi-mismatch-error' was caught: warning: failed to load '(gnu tests install)': Backtrace: [...] ERROR: In procedure display-error: Wrong number of arguments to # Now you get warnings and error reports as intended: warning: failed to load '(gnu tests install)': In procedure abi-check: : record ABI mismatch; recompilation needed warning: failed to load '(gnu tests ssh)': In procedure abi-check: : record ABI mismatch; recompilation needed * guix/records.scm (print-record-abi-mismatch-error): Remove. Remove top-level call to 'set-exception-printer!'. (abi-check): Use arguments as expected by 'display-error'.

records: Make a couple of procedures available at expansion time.

2018-05-31T16:13:08Z

* guix/records.scm (current-abi-identifier, abi-check): Wrap in 'eval-when'.

records: Insert record type ABI checks in constructors.

2018-05-23T08:21:02Z

* guix/records.scm (print-record-abi-mismatch-error): New procedure. : Add 'set-exception-printer!' call. (current-abi-identifier, abi-check): New procedures. (make-syntactic-constructor): Add #:abi-cookie parameter. Insert calls to 'abi-check'. (define-record-type*)[compute-abi-cookie]: New procedure. Use it and emit a definition of the 'current-abi-identifier' for TYPE. * tests/records.scm ("ABI checks"): New test.

records: Use 'make-struct/no-tail'.

2017-12-01T17:47:34Z

* guix/records.scm (make-syntactic-constructor): Use 'make-struct/no-tail' as 'make-struct' is deprecated as of 2.2.3.

guix: records: Add match-record.

2017-11-05T14:21:53Z

* guix/records.scm: New syntax-rule. Signed-off-by: Ludovic Courtès
