Fix two bugs in progress display across book detail, progress page, reader,
and sync modal templates:
1. Percentage was stored as 0.0-1.0 fraction but displayed as-if 0-100
(showing 0.5% instead of 50%). Multiply by 100 at the data source in
both GetAllProgress and GetAllProgressData handlers, and in the reader
route's ReadingProgress construction.
2. Progress bar width was never evaluated — { expr } inside style=".."
was rendered as literal text by templ, resulting in 0% width bars for
all items. Fixed by using templ's style={ expr } attribute syntax
which evaluates the Go expression (uses SanitizeStyleAttributeValues).
Also add format-aware progress display:
- Reader template: shows "45% · Page 89/196" for reflowable (estimated
pages), "127/342" for comics/PDFs (actual pages)
- Progress page: shows "Page X of Y (est.)" for reflowable, "X / Y"
for fixed layout
- Add FormatGroup and EstimatedPages to ProgressWithMedia struct
- Remove hardcoded totalPages=200 fallback in progress handler (now 0)
- Add fmt import to progress.templ for string formatting
The reader failed to load comics and manga (and any file with special
characters in its path) for two reasons:
1. FileURL was built with raw fmt.Sprintf instead of ResolveMediaURL,
so characters like '#' in paths (e.g. 'Annual #2') were interpreted
as URL fragments, truncating the path and causing 404s.
2. The Alpine x-init expression used raw string interpolation for config
values, so apostrophes in paths (e.g. "I'll Use My Appraisal Skill")
broke JavaScript parsing with 'Unexpected identifier'.
Fix by using utils.ResolveMediaURL for proper URL path encoding and
json.Marshal for the initReader config to safely escape all special
characters.
Replace direct error equality checks (err == pgx.ErrNoRows, err != http.ErrServerClosed)
with the idiomatic errors.Is() function throughout handlers, services, middleware, and app
startup. This correctly handles wrapped error chains.
Also replace a raw type assertion (*HTTPError) with errors.AsType[*HTTPError]() in the
error handler middleware for consistency.
Additionally, rename shadowed variables for clarity:
- sidecar.go: config -> sidecarConfig, systemConfig (shadowed package-level vars)
- media_scanner.go: uuid -> uuidString (shadowed the uuid package import)
Major rewrite of the web reader to properly interface with
@bookhoard/foliate-js, replacing the abandoned panel-detection
architecture with direct pan and zoom support built into the
foliate-js FixedLayout renderer.
Template (reader.templ):
- Fix critical bug: x-init config was using literal strings
'{ readerData.X }' inside a quoted attribute, which templ
treated as raw text and never interpolated. Values were never
actually passed to JavaScript. Now uses fmt.Sprintf() with
templ's expression attribute syntax ={ }.
- Pass fileUrl from server so foliate-js can open books directly.
- Redesign bottom bar with foliate-js parity: left/right navigation
buttons, progress slider with tick marks, and zoom controls
(zoom out, percentage display, zoom in, magnifier, pan/select
mode toggle for PDFs).
- Remove panel editor button and enablePanelDetection config.
- Add SVG icon styles for consistent reader controls.
Go types (templates/types.go):
- Expand ReaderMetadata with FormatGroup, MangaType,
ReadingDirection, FileURL, and LibraryID fields needed by
the reader frontend.
Router (internal/router/reader.go):
- Populate new ReaderMetadata fields from database values.
- Construct FileURL from library ID and file path for the
/uploads/library-{id}/* file serving route.
Reader JS (reader.ts):
- Full rewrite modeled on foliate-js Reader class, adapted for
Alpine.js. Opens books via view.open(fileUrl), accesses
view.renderer for zoom/pan/navigation, and wires up keyboard
shortcuts (+/-/0 for zoom, arrows for nav, Escape for magnifier).
- Uses view.isFixedLayout instead of importing FixedLayout class,
avoiding a TypeScript module resolution issue with the Vite alias.
Settings manager (settings-manager.ts):
- Remove dependency on deleted ReaderContext event bus.
- Export loadSettings/saveSettings/syncSettings directly as
standalone async functions.
Cleanup:
- Delete reader-context.ts and reader-events.ts (over-engineered
event system replaced by direct function calls).
- Remove panel_zoom_enabled from ReaderSettings type.
- Fix function signatures in reader.go (c echo.Context -> c *echo.Context)
- Replace non-existent UserHasLibraryAccess with GetUserVisibleLibraries pattern
- Implement SSR reader route in router/reader.go with proper access control
- Add inline library access checking following existing codebase patterns
- Fix ReadingProgress struct to use LastReadAt instead of CreatedAt/UpdatedAt
- Ensure all reader endpoints use consistent library access validation
This provides the backend foundation for the reader feature with proper
access control and SSR rendering capabilities.
