2026-06-28Refactor over-length functions into ~30-line helpers (vr0)Paul Buetow
Pure, behavior-preserving refactor: extract _-prefixed helpers from six functions that exceeded the project's 50-line threshold, leaving each original as a thin orchestrator. Generated HTML, dry-run output, shuriken.json, EXIF cache behavior and the flush-grid layout are all byte-identical (full test suite green). Refactored: - _generation_metadata_json -> _generation_metadata_json_head + _generation_metadata_json_settings - print_dry_run_plan -> _print_dry_run_settings + _print_dry_run_files - _photo_exif_tooltip_text_from_values -> _collect_exif_tooltip_parts + _emit_exif_tooltip_parts - cached_photo_identify_output -> _rebuild_photo_identify_cache - render_album_pages -> _render_album_page (one page record) - append_preview_grid -> _roll_and_align_page_tiles + _emit_page_tiles (uniquely-named namerefs to avoid circular-nameref) Left intact (delicate errexit/trap management that must stay in one function scope, where a split would change semantics): source_template_file, refresh_splash, generate_staged, replace_dist_with_staging.

2026-06-28Centralize DIST_DIR-derived paths via working_dir/exif_cache_dir helpersPaul Buetow
The EXIF cache dir ($(dirname "$DIST_DIR")/cache/exif) was recomputed inline, byte for byte, in both cached_photo_identify_output (read/write) and clear_exif_cache (--force/--clean removal). The plain parent of DIST_DIR (dirname "$DIST_DIR") was likewise recomputed in metadata-cache and in action.source.sh's staging-artifact cleanup. Extract two helpers computed once from DIST_DIR: - working_dir() in config.source.sh (next to existing_parent_dir, the other DIST_DIR-parent resolver): plain `dirname "$DIST_DIR"`. - exif_cache_dir() in metadata-cache.source.sh (owns the EXIF cache): `working_dir()/cache/exif`. Route cached_photo_identify_output, clear_exif_cache, and clean_generation_staging_artifacts through them so the cache reader and the cleaner can never drift to different directories. Paths are byte-identical to the prior inline code (dirname semantics, cache/exif suffix, trailing-slash and relative/absolute handling all preserved). Stale "recompute the cache dir" comments removed; helpers document the path once. Add a unit test asserting the helpers agree and resolve beside dist for several DIST_DIR shapes. Broader DIST_DIR parameterization of leaf pipeline helpers was intentionally left out of scope (only the duplicated path computation is centralized here).

2026-06-27Fix src/shuriken.sh lib source list missing 5 modulesPaul Buetow
Running `bash src/shuriken.sh --generate ...` directly from a source checkout printed "command not found" for camera_label_from_make_model, photo_exif_values_to and cached_photo_identify_output for every photo, silently emptying EXIF tooltips/details and, with STATS_PAGE=yes, omitting the whole stats/ tree. The hand-maintained source list inside the SHURIKEN_LIB_SOURCES_BEGIN/END marker block had drifted from the authoritative Justfile LIB_SOURCES, missing metadata-label, metadata-cache, stats-aggregate, stats-render and stats-filter-album. `just build` replaces the marker block with LIB_SOURCES when generating bin/shuriken, so the installed binary and the bin-based test suite never noticed; only direct src execution was affected. - Add the 5 missing `source` lines to the marker block in the same order as Justfile LIB_SOURCES, so the two lists now match exactly. - Add tests/cli.sh case test_lib_sources_match_justfile_lib_sources that extracts the marker-block module names and asserts they equal the Justfile LIB_SOURCES (same set and order) to prevent future drift. - shellcheck --check-sourced now follows the 5 newly-sourced libs; suppress the cross-module nameref false positives (SC2178/SC2128/ SC2154) with explained directives and genuinely fix SC2004 (counts_ref[$key] -> [key]) and quote the TITLE default (${TITLE:-}). bin/shuriken changes only by these propagated lib edits; the marker-block source list it generates is unchanged.

2026-06-24Split album-metadata.source.sh into focused modules (6r0)Paul Buetow
album-metadata.source.sh aggregated six unrelated concerns. Move each along its existing seam (pure mechanical move, no logic changes): - EXIF presentation (photo_exif_details_html, tooltip helpers, the _photo_exif_values_to wrapper) stays in album-metadata.source.sh, which is now EXIF-presentation only. - File counting (count_files, count_incoming_images, count_tree_files) -> image.source.sh, which already owns incoming_image_files; count_incoming_images is a direct wrapper of it. - Tarball naming (tarball_name_plan, generated_tarball_name) -> archive.source.sh, which already owns tarball()/resolve_tar_opts. - Generation metadata + JSON (_collect_generation_metadata, _generation_metadata_json, write_generation_metadata) -> new generation-metadata.source.sh. - Dry-run (dry_run, collect_dry_run_*, print_dry_run_plan) -> new dry-run.source.sh. - clear_exif_cache -> metadata-cache.source.sh, next to the cache primitive cached_photo_identify_output. LIB_SOURCES (Justfile + src/shuriken.sh): insert generation-metadata and dry-run right after album-metadata, before album-render/album. They depend on image, archive, template and metadata-cache (all earlier or runtime-only calls), and are consumed by the album coordinator and the dry-run CLI action, which come later. bin/shuriken regenerated via just build. File-header comments updated to reflect the new homes. just test, just shellcheck, just check-generated and git diff --check all pass. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
2026-06-24Promote single canonical identify-stream EXIF parser into metadata-cache (8r0)Paul Buetow
The `identify -verbose` EXIF-line regex and its array-fill loop were duplicated in three places that had already drifted: album-metadata's photo_exif_details_html and _photo_exif_values_to (exif: only) and stats-aggregate's _stats_parse_identify_stream (exif: plus a native Geometry -> __geometry path). Promote one canonical parser, photo_exif_values_to, into metadata-cache.source.sh next to its sibling cache primitive cached_photo_identify_output. It reads an identify stream from stdin and fills a nameref associative array; it is a strict superset of all three former sites (bare exif: tag keys plus the synthetic __geometry key). - stats accumulate_photo_stats now calls photo_exif_values_to (stdin); _stats_parse_identify_stream is removed. - album _photo_exif_values_to is a thin wrapper that pipes cached_photo_identify_output through the canonical parser. - album photo_exif_details_html consumes the same parser and skips the __geometry key it does not display. metadata-cache is sourced before both consumers in LIB_SOURCES, so the canonical parser is available at use time. Regenerated bin/shuriken via `just build`. Added test_shared_identify_parser_returns_exif_and_geometry asserting one parse yields both an exif: key and __geometry.

2026-06-17pn0 decouple stats from album internalsPaul Buetow
Stats reached directly into album-module internals: the private global ALBUM_VIEW_PAGE_BY_PHOTO and the EXIF cache reader cached_photo_identify_output. Introduce a clean boundary, behaviour and generated HTML byte-identical. - Promote the EXIF identify cache primitive (cached_photo_identify_output plus its private helpers photo_cache_signature and print_cached_photo_identify_output) out of album-metadata.source.sh into a new shared src/lib/metadata-cache.source.sh, sourced before both album and stats (right after metadata-label in LIB_SOURCES). It is a low-level metadata primitive used by both consumers, so it no longer belongs to album internals. Signature/behaviour unchanged. - Add album_view_page_for_photo accessor in album-render.source.sh as the documented public API; keep ALBUM_VIEW_PAGE_BY_PHOTO as the album's private backing store. stats-filter-album.source.sh now calls the accessor instead of indexing the global, so a change to album page naming/caching stays contained in the album module. - Add test_album_stats_decoupling_boundary asserting the accessor returns the backing-store value and that the assembled bin/shuriken keeps the cache primitive in the shared module and no longer indexes the global from the stats filter section. Existing stats/album tests unchanged. Verified: 3-image fixture (STATS_PAGE=yes, fixed seed) diff -r of stashed original vs new build is byte-identical across all 47 dist files (only the inherent generated_at timestamp normalized). just test, just shellcheck, just check-generated and git diff --check all pass.
