2026-05-25T15:09:55+00:00

the resulting list has the correct license followed by one instance
of the symbol 'unknown-license!

tests: import: gem: Add test for unrecognized license identifiers.

2026-05-25T15:09:43+00:00

Exercises the map in 4f78d33f0 where every license
string is unrecognized, so the resulting package should have
(license (list unknown-license! unknown-license!)).

* tests/import/gem.scm (test-gibberish-licenses-json): New fixture.
  ("gem->guix-package with gibberish license identifiers"): New test.

import: gem: Use spdx-string->license for license lookup.

2026-05-25T15:09:12+00:00

Similar to what was done for the crate importer in 263a267b75.

* guix/import/gem.scm (string->license): Try spdx-string->license first,
  returning symbols instead of license objects.  Fall back
  to the existing hardcoded table for non-SPDX strings.
  (make-gem-sexp): Remove license->symbol calls;
  licenses are now symbols directly.
* tests/import/gem.scm (test-spdx-json): New fixture.
  ("gem->guix-package with SPDX license identifiers"): New test.

import: gem: Fix null at home-page.

2026-05-25T15:08:11+00:00

The RubyGems API returns "homepage_uri": null for gems with no homepage.
guile-json parses JSON null as the Guile symbol 'null', which passes
through into the generated package sexp as (home-page null)—an unbound
variable error at evaluation time.

* tests/import/gem.scm (test-no-homepage-json): New fixture.
  ("gem->guix-package, bald homepage_uri"): New test.
* guix/import/gem.scm (non-empty-string-or-false): New procedure.
  ()[home-page]: Use it.
* guix/import/utils.scm (non-empty-string-or-false):
  New exported procedure, moved to here...
* guix/import/gem.scm (non-empty-string-or-false): ...from here...
* guix/import/pypi.scm (non-empty-string-or-false): ...and here.
