- New Print::printJson() method reads image metadata and serializes it with nlohmann::ordered_json. - buildMetadatumJson() handles per-tag JSON construction - serializeMetadataJson() template filters containers by the same grep/key/unknown flags used by the existing printMetadata() path.
- TestJsonBasicStructure: validates top-level keys, per-tag field presence and types on DSC_3079.jpg - TestJsonFileNotFound: verifies correct stderr message and retval=255 for missing files - TestJsonWithGrepFilter: -g flag restricts tags to matching keys - TestJsonWithKeyFilter: -K flag limits output to exact key (ordered -K before -p j to work around printMode_=pmList side-effect at exiv2.cpp:394) - TestJsonWithGrepNoMatch: grep with no hits produces empty arrays - TestJsonIsValidJson: smoke test that stdout is parseable JSON
