createFontRowSizeResolver was reaching into TextLayoutEngine, which
internally called pretext's heavy layoutWithLines and then walked
per-grapheme cursors to build chars arrays. The resolver discarded all
that work and used only totalHeight.
Replace with direct prepare + layout from @chenglou/pretext — pretext
docs explicitly recommend layout() (not layoutWithLines) for the resize
hot path: pure arithmetic on cached segment widths, no canvas calls, no
string allocations.
Test spies on TextLayoutEngine.prototype.layout migrated to vi.mock-ed
pretext layout (pretext's ESM exports are frozen — vi.spyOn fails with
"Cannot redefine property").
TextLayoutEngine marked @deprecated since it has no remaining
consumers; slated for removal after a release cycle.
Both names were vague or overloaded:
- fontStore / FontStore -> fontCatalogStore / FontCatalogStore
Three font-related stores live in this slice; the new name names the
paginated catalog specifically.
- appliedFontsManager / AppliedFontsManager -> fontLifecycleManager /
FontLifecycleManager
"Applied" collided with the filter-side appliedFilterStore (different
meaning). The class actually orchestrates a load-use-evict lifecycle
with FontBufferCache + FontEvictionPolicy + FontLoadQueue
collaborators, so "Manager" is justified. Companion types file moved
alongside (appliedFonts.ts -> fontLifecycle.ts).
Directories, file basenames, factory (createFontStore ->
createFontCatalogStore), and the AppliedFontsManagerDeps interface all
renamed. All consumers (ComparisonView, SampleList, FontList,
FontApplicator, FontVirtualList, FilterAndSortFonts bindings,
createFontRowSizeResolver, mocks) updated.
The byId font fetch was a verb-oriented capability with a single
consumer driven by a feature need (materializing comparison picks).
That shape belongs at the feature layer, not on the entity.
Move:
- entities/Font/model/store/batchFontStore -> features/FetchFontsByIds/model/store/fontsByIdsStore
- Class BatchFontStore -> FontsByIdsStore
entities/Font retains the transport primitives (fetchFontsByIds,
seedFontCache) and the keyspace (fontKeys); the feature wraps them in
the reactive store. comparisonStore now imports FontsByIdsStore from
the new feature. The proxy API is imported via direct path so vi.spyOn
on the source module still observes the call.
Structural:
- Merge factory + singleton from lib/settingsManager and model/state into
one model/store/typographySettingsStore/ slice
- Drop now-empty lib/ and model/state/ directories
Semantic:
- Rename feature SetupFont -> AdjustTypography (the feature owns
continuous typography adjustment, not one-time font setup)
- Drop "Manager" from TypographySettingsManager -> TypographySettingsStore
(class + factory); singleton typographySettingsStore unchanged
All consumers (Character, Line, SampleList, SliderArea, FontSampler,
comparisonStore) updated. Public barrel signature changed: now exports
createTypographySettingsStore and type TypographySettingsStore.
The feature does not fetch fonts — that lives in \$entities/Font's
fontStore. It owns the user's filter selections, sort preference, and
search-by-name query that drive the listing. The new name describes what
it actually does.
Directory + every \$features/GetFonts import path updated; no symbol
renames in this commit.
The 'filters' + 'filterManager' pair didn't reveal the schema-vs-selection
split. Rename to reflect the actual roles:
- FiltersStore / filtersStore → AvailableFilterStore / availableFilterStore
- createFilterManager / FilterManager → createAppliedFilterStore / AppliedFilterStore
- filterManager singleton → appliedFilterStore
- mapManagerToParams → mapAppliedFiltersToParams
Directories and file basenames follow the new singleton names. Public
barrel signature updated; all consumers (Search, FontSearch, Filters,
FilterControls) point at the new identifiers.
Export createSortStore and FiltersStore so per-test instances can be
constructed without sharing singleton state. Add unit tests covering:
- sortStore: default + custom init, display→API value mapping, set()
idempotency, singleton shape
- filters: empty initial state, fetch population, single-call dedup,
error path, cached-fetch reuse across observers
Group each store with its tests under its own directory to match the
filterManager layout.
Dynamic import inside the vi.mock('$entities/Font') factory was missed
when batchFontStore was relocated into its own subdirectory in 1573950.
Restores the previously-failing comparisonStore test suite (9 tests) and
clears the lingering TS error in svelte-check.
Collapse the three duplicated getGroup/map/length-guard chains into a
single selectedIn helper. Drop the unnecessary `as string[]` casts —
Property<TValue extends string>.value already yields string at the call
site.
Add unit tests covering empty query, populated query, missing group,
empty group, single + multi selection, unknown group ids, and the
combined param shape.
Align the slice with the project-wide convention (entities/Font,
entities/Breadcrumb, features/ChangeAppTheme all use model/store/;
CLAUDE.md spec calls for store/). Move bindings, filters, and the
filterManager subdir out of the now-removed model/state/ directory.
Merge the factory previously in lib/filterManager/ with the singleton
previously in model/state/manager.svelte.ts into a single
model/state/filterManager/ slice. The factory builds stateful runes-backed
objects, so it belongs alongside the singleton in model/, not in lib/.
lib/ now contains only the pure mapManagerToParams transform.
Public barrel signature unchanged.
Move the filtersStore → filterManager.setGroups $effect.root out of
manager.svelte.ts into bindings.svelte.ts so all cross-store reactive
wiring for the feature lives in one place. manager.svelte.ts now only
constructs and exports the singleton.
Move the duplicated $effect blocks that mapped filterManager and sortStore
into fontStore params out of Search, FontSearch and FilterControls into a
single $effect.root in features/GetFonts/model/state/bindings.svelte.ts.
Consumers now bind to the manager/store directly; the bridge is installed
once via a side-effect import from the feature barrel.
