Connect the existing progress_mode setting dropdown to the reader's
progress display. Four modes are now functional:
- pages: overall percent + page/location number (default, existing)
- chapter: chapter title + page X / Y within current section
- percentage: overall percent only
- time-left: percent + estimated time remaining via reading speed API
The progress display in the bottom bar is now clickable to cycle through
modes with immediate visual feedback. The settings dropdown is bound
with x-model for persistence. Reading speed is fetched once on init
from the backend reading-speed API for time-left estimates.
Regenerated all _templ.go files after running templ generate. Changes
include updated FileName references (relative path normalization) and
line number adjustments from the templ code generator.
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
Add fields to ReaderMetadata and ReadingProgress template types to support
KOReader-like progress display:
ReaderMetadata:
- TotalCharacters: from media item, used for estimated page calculation
- EstimatedPages: computed via sync.EstimatedPages()
ReadingProgress:
- Chapter: current chapter index from reading_progress
- ChapterProgress: within-chapter progress (0-100, multiplied from DB fraction)
- FormatGroup: item format for conditional display logic
These fields enable format-aware progress display (pages for comics/PDFs,
estimated pages for reflowable, percentage for all).
Reflowable ebooks (EPUBs) don't have inherent page numbers since layout
depends on device settings. Add an EstimatedPages() function that converts
total character count to an estimated print page count using the industry
standard of 1800 characters per page.
This provides a consistent, device-independent page count for progress
display (e.g., "Page 89 of 196" for a reflowable EPUB), matching how
KOReader and similar readers handle the same problem.
The DetectChapters function in reader.go was serializing chapter detection
results to JSON but then discarding the bytes with `_ = metadataBytes`
instead of writing them to the database. This meant chapter_metadata in
media_items was never populated, forcing re-detection on every request.
Replace the no-op discard with an actual UpdateMediaItemChapterMetadata()
call using the existing sqlc-generated query.
The media scanner never populated page_count or total_characters in
media_items, leaving progress display and reading position calculations
with no reliable data. This commit fixes data population for all formats:
Comics (CBZ/CBR/CB7/CBT):
- Add countArchiveImages() helper that walks archive entries and counts
image files (.jpg, .jpeg, .png, .gif, .webp)
- Call it during comic metadata merge to set metadata.PageCount
PDFs:
- Extract pdfInfo.PageCount from the pdfcpu library (already available
from PDFInfo call, just never used) and set metadata.PageCount
Reflowable EPUBs:
- Use book.AllChaptersText() to compute metadata.TotalCharacters
- Use book.ChapterCount() to set metadata.ChapterCount
Fixed-layout EPUBs (manga/comics in EPUB format):
- Merge .epub into the .cbz case in countArchiveImages since both are
ZIP archives with images
- Detect fixed-layout EPUBs via DetectFixedLayoutEPUB() in both the
Calibre sidecar path (mergeMetadata) and the no-sidecar path
(extractMetadata), counting images when fixed-layout is detected
Format group on creation:
- Remove the guard condition on UpdateMediaItemFormatGroup so that
format_group, is_reflowable, and has_fixed_layout are set immediately
for every new item (not just items with text data)
- Use DetectFixedLayoutEPUB() instead of hardcoding all .epub as
reflowable, correctly classifying fixed-layout EPUBs
Also pass PageCount to CreateMediaItem and add PageCount,
TotalCharacters, and ChapterCount fields to the MediaMetadata struct.
The web reader had all the infrastructure for progress persistence
(updateReadingProgress/getReadingProgress API functions, PUT/GET
endpoints, database queries) but the reader.ts never called them.
Changes:
- Add debounced (2s) saveProgress call on every relocate event that
PUTs percentage, current_page, total_pages, and epubcfi to the
existing /api/media-items/:id/progress endpoint
- Replace renderer.next() with view.init({ lastLocation }) to restore
the reader to the last saved position on load (CFI first, then
fraction fallback, then default first page)
- Pass savedPercentage and savedCfi from server-side progress data
through readerInitExpr config to the JS initReader function
- Add mediaItemId and saveTimeout to the Alpine data object
This fixes both the blank /progress page and the missing progress
section on book detail pages — both were empty because the
reading_progress table never received any data from the web reader.
Go's new() builtin takes a type and allocates a zero value — it cannot
wrap an expression. All instances of new(someExpression) were compile
errors. Replace each with a local variable assignment and address-of
operator.
Affected files:
- handlers/koreader.go: progress field pointers (Chapter, Page, etc.)
- handlers/kobo.go: pagesRemaining pointer
- handlers/queue.go: uuidPtrToString and timestamptzPtrToString helpers
- router/reader.go: bookmark pageNumber and chapterNumber pointers
- services/media_scanner.go: validation error message pointers
- services/worker.go: StartedAt and CompletedAt timestamps
- sync/offline.go: GetDeviceStatus return pointer
- tests/device_test.go: SyncEnabled and SyncFrequencyMinutes pointers
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.
When switching libraries via TypeScript, renderBookCard() built book
cards as <div> elements with data-action="view-book" for event
delegation, but the click handler was commented out — making books
unclickable after any library switch. The SSR path used proper <a> tags.
Now renderBookCard() wraps cards in <a href="/media/{id}"> to match the
SSR BookCard template, so book links work identically regardless of
whether content was server-rendered or client-rendered.
Also removed the dead view-book handler code and viewBook() stub.
Additionally fixed a listener re-registration bug where the input and
library-select change listeners were nested inside the click callback,
causing them to be registered N times after N clicks. Moved them to
initDashboard() scope so they register exactly once.
The back link in ReaderChrome used literal curly braces inside the href
attribute string (href="/media-items/{ metadata.MediaItemID }") which
doesn't interpolate the variable in templ. Changed to use the correct
templ expression syntax: href={ "/media/" + metadata.MediaItemID }.
Also fixed minor formatting issues:
- Normalize whitespace in comment after closing div
- Collapse empty navigator-viewport div to single line
Remove hardcoded values for database/environment IDs (media_item_id,
library IDs, collection_id, user_id, etc.) and mark them as secret so
that changing them per machine won't keep syncing to git.
Cover image URLs with special characters like parentheses, #, ?, or
spaces would break because browsers interpret them as URL delimiters.
Apply url.PathEscape() per path segment in ResolveMediaURL so the
server can correctly resolve files like "Wonder Woman (2016) #001.cbz.cover.jpg".
Also adds a package doc comment and fixes the exported function comment.
Comic archive formats (.cbz, .cbr, .cb7, .cbt) and .kepub files were
falling through to the default case in extractMetadata(), which only
set the title from the filename. This meant ComicInfo.xml was never
parsed and no cover images were extracted for comics without a Calibre
metadata.opf sidecar file.
The fix adds dedicated switch cases:
- .cbz/.cbr/.cb7/.cbt: calls mergeMetadata() with nil, which triggers
existing ComicInfo.xml parsing (title, series, issue number, writer,
publisher, genre, reading direction, etc.) and cover image extraction
from the archive. Falls back to sidecar cover if no image is found.
- .kepub: treated the same as .epub since KEPUB is an EPUB variant,
enabling full metadata and cover extraction.
TestCollectionSearchLibraryFilter's 'invalid library_id' case was
expecting a 200 with empty results, but the search handler correctly
returns 404 when no results are found. The test also consumed the
response body for debug logging then tried to JSON-decode the same
body (causing EOF). Add expectedStatus field to the test struct and
return early when a specific non-200 status is expected.
Three issues fixed in processing_issues_test.go:
- Empty UUID: handler returns 400 (uuid.Parse rejects empty string), not 404.
Fix expectedStatus in both List and Stats validation tests.
- Path traversal: raw '../../' in URL creates extra path segments that don't
match the route. Use url.PathEscape so the string is treated as a single
path parameter, letting the handler reject it with 400.
- SQL injection: raw special characters (semicolons, quotes) caused
httptest.NewRequest to panic. url.PathEscape prevents the panic and the
handler rejects the decoded value via uuid.Parse.
- Remove unsupported 'audiobooks' library type from
TestProcessingIssuesDifferentLibraryTypes (only ebooks/comics/manga exist
in the database schema).
The setupTestServer() helper in test_helpers_test.go was not creating
a ProcessingIssuesHandler and not passing one to the router config,
causing a nil pointer dereference when any processing issues route was
hit during tests. Add handler creation and wire it into routerConfig
to match how cmd/server/main.go does it.
Both ListProcessingIssues and GetProcessingIssueStats were reading the
URL parameter 'libraryId', but the routes in internal/router/library.go
define the param as ':id'. This caused both endpoints to always fail with
an invalid library ID error since c.Param('libraryId') returns an empty
string that can't be parsed as a UUID.
Remove redundant type conversions that Go 1.26 makes unnecessary or that
were already no-ops:
- uuid.UUID(x.Bytes) → x.Bytes (uuid.UUID is [16]byte, same as pgtype UUID Bytes)
- pgtype.UUID{Bytes: [16]byte(u), Valid: true} → pgtype.UUID{Bytes: u, Valid: true}
- (*time.Time)(&x.Time) → &x.Time
- json.RawMessage(x) → x where x is already []byte
- []byte(stringVal) → stringVal where []byte is expected
- int()/int64()/byte() casts on values already of the target type
- Decompressor(fn) → fn (type is identical)
Handle previously ignored error returns:
- collections.go: check json.Unmarshal error in GetCollection
- conversion_service.go: check fileSize.Scan() error
- app_test.go: check app.Shutdown() error in benchmark
DismissAllResolved was calling ListSyncConflictsByUser which filters to
'unresolved' conflicts only, so it could never find the user_resolved or
bulk_resolved conflicts it was trying to delete. The query always returned
an empty set, making dismiss-all a no-op.
Fix the leading space in three SQL query name annotations (ListConflictsByUser,
ListAllConflictsByUserAndStatus, CheckForProgressConflicts) that prevented
sqlc from generating their Go functions. Regenerate the query code and swap
DismissAllResolved to use ListConflictsByUser (no status filter) — the
existing Go loop already filters by resolution_status.
The builder stage was previously bumped to Go 1.26 but the test-runner stage
remained on Go 1.25, causing 'go.mod requires go >= 1.26.0' errors during
test execution.
Go 1.26 introduced stricter validation of replace directives in dependency
go.mod files, which broke 'go install sqlc@latest' (sqlc v1.31.0 has replace
directives). Replace go install with a direct binary download from GitHub
releases, matching the existing kepubify download pattern.
Bump test-runner from golang:1.25-alpine to golang:1.26-alpine to match the
go.mod requirement.
Replace all unhandled resp.Body.Close() calls throughout the test suite:
- Deferred calls: replace 'defer VAR.Body.Close()' with a closure that explicitly
discards the error via 'defer func(Body io.ReadCloser) { _ = Body.Close() }(VAR.Body)'
- Immediate calls: replace 'VAR.Body.Close()' with '_ = VAR.Body.Close()'
Replace all unhandled json.NewDecoder(VAR.Body).Decode(&x) calls with error capture
and require.NoError assertion. Files using httptest.ResponseRecorder (collections_preview,
processing_issues) use 'err :=' declaration; suite-style tests (scanner_integration,
dashboard_integration) use s.T() instead of t.
Replace direct error equality check with errors.Is() in media_scanner_hash_test.
In analytics_test.go, improve defer patterns by capturing resp.Body as a named parameter
to avoid stale references, and add require.NoError() checks on all json.NewDecoder().Decode()
calls that were previously silently ignoring decode errors.
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)
Add the 'reading_mode' field with 'dark' | 'light' values to the
ReaderSettings TypeScript interface, preparing the frontend for a
dark/light reading mode toggle.
Two changes to EPUB metadata extraction:
1. Restructure extractMetadata so that fixed-layout detection and cover
extraction always run for EPUBs, even when extractEPUBMetadata returns
an error. Previously, a partial failure from the EPUB parser would skip
cover and format detection entirely, leaving books without covers.
2. Remove the language restriction (ja/jpn) from manga reading direction
detection. Manga tagged with 'manga' should default to RTL regardless
of the language metadata, since the tag is an explicit signal from the
user or metadata source.
In applyProgressResolution and applyResolution, currentPage and totalPages
were unconditionally read from existingProgress even when the preceding
query returned err (no rows). This caused a nil pointer dereference when
no existing reading progress existed for a media item. Now declare the
variables as zero-value pgtype.Int4 and only populate them from
existingProgress when err is nil.
Replace direct equality checks (err != pgx.ErrNoRows) with the idiomatic
errors.Is(err, pgx.ErrNoRows) pattern. This is the recommended Go practice
for error comparison as it correctly handles wrapped errors from error
chains, making the code more robust against future refactoring that might
wrap errors with fmt.Errorf and %w.
When opening a sevenzip archive, the init() method calls sr :=SevenZipReader()
but never checked if sr was nil before using it. This could cause a nil
pointer dereference when processing malformed or empty archives. Add an
explicit nil check returning errFormat early if the subreader is nil.
Also fixes a minor import grouping whitespace issue.
Replace the previous mock/httptest-based conflict tests with
integration tests that exercise the full HTTP stack against a live
test server with a real database. Changes include:
- Add shared test helpers (setupConflictTest, createTestConflict,
makeConflictData) to reduce boilerplate across test files
- Split monolithic TestConflictDetection and TestConflictsBulkOperations
into focused test functions per scenario
- Test conflict detection, bulk resolution (most_recent, highest_progress,
manual strategies), and edge cases (empty IDs, invalid UUIDs,
unauthorized access)
- Verify actual database state after resolution, not just HTTP response
Add table-driven tests for the conflict handler's source selection
methods: GetMostRecentSource, GetHighestProgressSource, and
GetEarliestSource. Covers cases where each device wins, ties, and
missing/invalid data.
strings.Title has been deprecated since Go 1.18 because it does not
handle Unicode properly. Replace it with cases.Title from
golang.org/x/text which correctly handles language-specific title
casing. Applied to breadcrumb generation and document title formatting.
Simplify pointer creation in media scanner validation messages and worker
job timestamps by using inline new() instead of local variable + address-of.
In media_scanner.go this cleans up three validation error message returns
(manga/comics library format checks). In worker.go it simplifies StartedAt
and CompletedAt timestamp assignments.
Simplify pointer creation across kobo, koreader, and queue handlers by
replacing the two-step pattern (assign to local, then take address) with
inline new() calls. This reduces verbosity without changing behavior:
Before:
remaining := int(a - b)
pagesRemaining = &remaining
After:
pagesRemaining = new(int(a - b))
Covers page calculations, chapter/progress fields, UUID formatting,
and timestamp string conversions.
Replace the original 5-theme allowlist (light, sepia, dark, night,
high-contrast) with a richer 20-theme palette organized into tonal
families: neutrals (light, paper, slate, oled), warm tones (sepia,
parchment, warm, candlelight), cool tones (azure, sky, arctic, frost),
and evening tones (dusk, sunset, twilight, forest, moss, solarized).
The backend validator in UpdateSettings now accepts all 20 theme names,
and the frontend Tailwind build is updated to include the new theme CSS
variables and preflight reset.
- Remove Playwrite NZ Guides test font and all references (FONT_MAP,
FONT_FILES, reader-fonts.css, dropdown option, font files)
- Move settings panel from left sidebar to right sidebar (left sidebar
now only contains TOC)
- Move Restore Defaults button from top bar icon to a styled button
inside the settings panel, side by side with Done button
The paginator renders inside a sandboxed iframe that blocks @font-face
URL fetches. Fonts were never loading — all font-family rules fell back
to the generic 'serif' system font, making every reading font identical.
Fix: fetch font files on the parent page, create blob: URLs via
URL.createObjectURL(), and use those blob URLs in the @font-face rules
injected into the iframe via setStyles(). Blob URLs are always
same-origin with the creating document, so the sandboxed iframe can
access them with allow-same-origin.
Also added Playwrite NZ Guides as a test font for verifying font
switching works.
Fonts weren't loading because the paginator renders inside a sandboxed
iframe. @font-face declarations in the parent page's CSS are invisible
to the iframe's document. Even injecting @font-face rules via
setStyles() may not trigger font loading in sandboxed iframes.
Fix: inject a <link> to reader-fonts.css directly into the iframe's
document on each section load, so @font-face declarations are parsed
in the iframe's own document context where font-family rules can
reference them.
Also:
- Remove foliate-themes.css entirely (no longer needed)
- Set viewport background color directly via JS using THEME_COLORS map
- Remove reading theme CSS classes from viewport element
background: none on html/body exposed the iframe's default black
background in gaps around the content. Now uses background-color
matching the theme color, and stops forcing background on body *
which caused black bars around page margins.
The paginator renders book content inside a sandboxed iframe within a
closed shadow DOM. @font-face declarations from the parent page's
reader-fonts.css are NOT available inside the iframe's document context.
All font-family rules fell back to the generic 'serif' system font,
making every reading font look identical.
Fix: prepend all @font-face declarations (Literata, Crimson Pro,
Source Serif 4, EB Garamond, Libertinus Serif, Noto Serif, Charis SIL,
IBM Plex Serif) into the CSS string returned by getCSS(), so they're
injected into the iframe via renderer.setStyles().
Comic Sans MS is a system font not available on Linux. The cursive
fallback rendered as a script font, giving false negatives. All 8
loaded reading fonts are serif fonts loaded via @font-face, so they
intentionally look similar — font switching is confirmed working.
Studied grimmory-tools/grimmory's ebook-reader style.service.ts and adopted
their approach:
- Replace CSS custom property resolution (getComputedStyle) with a hardcoded
THEME_COLORS map containing concrete fg/bg/link values for all 18 themes
in both light and dark modes. No more variable resolution failures.
- Font family now targets body + body * with !important, overriding book CSS
on every element (matching grimmory's approach).
- Colors use grimmory's aggressive pattern:
html, body { color: ... !important; background: none !important; }
body * { color: inherit !important; background-color: ... !important; }
This forces reading theme colors on ALL book elements, overriding inline
styles and book stylesheets.
- Line height uses !important on p, li, blockquote, dd to override book CSS.
- Removed fragile getComputedStyle calls entirely. getCSS() now receives
themeName and themeMode parameters for direct color lookup.
- Add Comic Sans MS as a test font option to verify font switching works
- Add !important to background-color and color in getCSS() to prevent
book CSS from overriding user's reading theme colors
- Expand font size range from 12-24px to 10-40px, bump default to 18px
- Expand line height range from 1.0-2.5 to 0.8-3.0
- Add restoreDefaults() method that resets reading theme, font, size,
line height, and justify/hyphenate to sensible defaults
- Add ↩️ restore defaults button in top bar underneath the settings gear
Two root causes fixed:
1. Reading theme CSS variables were on document.body, leaking font/color
into chrome UI. Now scoped to #reader-viewport so chrome keeps its own
theme (system font, --text-primary colors) while the reading area uses
reading theme colors/background.
2. getCSS() never received font family, font size, or line height settings.
The settings UI (dropdowns, sliders) saved values but they were never
injected into the book's shadow DOM. Now getCSS() accepts all four
settings and generates proper CSS rules for them.
Changes:
- Wrap foliate-view in #reader-viewport div (absolute positioned between
chrome bars)
- getCSS() reads computed style from #reader-viewport, not document.body
- getCSS() params expanded: fontFamily, fontSize, lineHeight, justify,
hyphenate (removed unused 'spacing')
- Added FONT_MAP to translate setting keys to CSS font-family values
- applyTheme() targets #reader-viewport instead of document.body
- Removed dead #reader-viewport typography rules from foliate-themes.css
(shadow DOM doesn't inherit outer styles), kept only background-color
- Position foliate-view with absolute inset-x-0 top-[52px] bottom-[52px]
so book content renders between the fixed header and footer bars instead
of behind them
- Confirmed removal of foliate-themes.css base typography was correct:
body color now comes from chrome theme's --text-primary (light for
dark chrome themes like tokyo-night)
Two fixes:
1. Remove base typography block from foliate-themes.css. The html/body
rules were unlayered CSS that overrode the chrome theme's layered
body styles, causing dark reading theme text colors (--reader-text)
to apply to the outer chrome UI on dark backgrounds. These styles
are only meant for the shadow DOM, which getCSS() already handles.
2. Move missing typography rules (img, blockquote, a, p orphans/widows)
into getCSS() so the shadow DOM still gets them.
3. Add sun/moon emoji indicators to the light/dark toggle switch.
Add explicit light/dark mode toggle switch to the reading theme settings.
The reading mode defaults based on the chrome theme (dark chrome themes
like tokyo-night default to dark reading mode).
- Add readingMode property to readerShell Alpine component
- Add toggleReadingMode() method that toggles dark class on body
- Add detectChromeDarkMode() to infer default from chrome theme
- Update applyTheme() to add/remove dark class and persist reading_mode
- Add toggle switch UI in settings panel (blue pill style, next to
Reading Theme heading)
- Add reading_mode to default settings in settings-manager
Books were failing to load because foliate-js fetches the file URL
without auth headers, getting rejected by JWT middleware. Also,
reading themes were not being applied because getCSS() didn't
inject background/text colors into the book iframe.
- Fetch book file with Bearer token, pass as File (not URL) to
view.open() so foliate-js can detect format via filename extension
- Add reading theme class to body so foliate-themes.css activates
the correct --reader-bg/--reader-text CSS variables
- Update getCSS() to read theme colors from outer page and embed
them in the iframe CSS string (background-color, color, link
color, selection color)
- Fix Alpine.start() deadlock: move call outside the alpine:init
listener so Alpine actually initializes
- Remove unused tocItem from relocate handler destructuring
- Replace apiGet/apiPut with direct fetch in settings-manager to
fix /api prefix mismatch (reader routes are at /readers/*, not
/api/readers/*)
The foliate-view custom element had no height, causing its shadow DOM
content to collapse to 0px. Books were loading but invisible.
- Add h-screen overflow-hidden to body for full viewport height
- Add block w-full h-full to foliate-view element
- Replace flex-grow with Tailwind grow class on progress slider
- Remove #progress-slider CSS rule from inline style block
(replaced by Tailwind grow utility)
Update NewDevDBSetup collection to create Ebook, Comic, and Manga
libraries with separate IDs (ebook_library_id, comic_library_id,
manga_library_id) instead of a single library_id.
- Fix CreateComicLibrary and CreateMangaLibrary to use correct
names, descriptions, and types instead of duplicating Ebook values
- Update NewDB.sh to run the full setup sequence: register user,
create all three libraries, add folders, then scan all
- Add AddEbookLibraryFolder, AddComicLibraryFolder, and
AddMangaLibraryFolder requests with per-type subfolder paths
- Add ScanAllLibraries request using bru.sendRequest() to scan
each library sequentially via the /api/scanner/scan endpoint
- Update Get Libraries (Admin) to save all three library IDs
- Update List Media Items requests to use ebook_library_id
- Rename library_id to ebook_library_id in Create Library and
Add Library Folder requests
- Add comic_library_id and manga_library_id to environment
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.
Update all library API request files to the current Bruno format
with proper settings blocks, updated sequence numbers, and cleaner
YAML formatting.
Add NewDevDBSetup collection with requests for creating comic, ebook,
and manga libraries, user registration, and folder configuration to
speed up development environment setup.
The string_to_array call in detect_fixed_layout_epub() had an extra
closing parenthesis after the '<img' delimiter, causing a SQL syntax
error that prevented the database container from initializing:
IF array_length(string_to_array(opf_content, '<img')), 1) - 1 > 50
Fixed to:
IF array_length(string_to_array(opf_content, '<img'), 1) - 1 > 50
Update the reader template to support dynamic configuration and manga metadata:
templates/reader_templ.go:
- Remove direct foliate-js/view.js script tag (integrated into reader.js)
- Add foliate-themes.css stylesheet for theming support
- Update initReader() call to accept configuration object with:
- mediaItemId: Unique media item identifier
- title: Media item title
- enablePanelDetection: Boolean for comic/manga panel detection
- libraryType: Media type for reader initialization
- formatGroup: Format category (ebook, comic, manga)
- mangaType: Manga subtype for specialized handling
- readingDirection: RTL/LTR/vertical reading direction
- Simplify theme to always use tokyo-night (theme handled in JS)
These changes enable the reader to dynamically configure itself based on
media item metadata, supporting enhanced manga reading features and
panel detection for comic formats.
Remove large dependencies that are not actively used in the codebase:
- jszip: Unused ZIP processing library
- pdfjs-dist: PDF rendering (handled by external library)
- @techstark/opencv-js: Computer vision operations
- @tensorflow/tfjs: TensorFlow.js machine learning framework
- @tensorflow-models/coco-ssd: COCO-SSD object detection model
These dependencies were related to experimental features that have been
replaced or moved to external processing. Removing them significantly
reduces bundle size and simplifies the dependency tree.
Retain only actively used dependencies like htmx, chart.js, lunr,
and the @bookhoard/foliate-js fork with panel detection support.
Apply Go 1.18+ language features and modern style:
internal/services/collection_service.go:
- Use map[string]any instead of map[string]interface{} (Go 1.18+)
- Use range clause with single variable for iteration-only loops
- Replace if-else chains with switch statements for better readability
- Remove explicit type initialization for zero values
internal/services/filters.go:
- Add Err prefix to custom error variable for error naming convention
internal/router/library.go:
- Use cfg.ProcessingIssuesHandler instead of local processingIssuesHandler variable
- Ensures proper dependency injection through router config
These changes follow current Go best practices and improve code readability.
Add frontend route /admin/libraries/:id/issues to display processing issues
management page for a specific library.
internal/router/frontend.go:
- Register GET /admin/libraries/:id/issues with admin middleware
- Fetch processing issue stats from database
- List processing issues for the library
- Convert database models to template types
- Render AdminProcessingIssues template with issues and stats
This provides the admin UI for viewing and managing processing errors that
occur during media scanning and import workflows.
Wire up the ProcessingIssuesHandler throughout the application:
cmd/server/main.go:
- Remove obsolete commented-out getTemplateUserWithTheme function
- Instantiate ProcessingIssuesHandler with database queries
- Add handler to router Config (with field alignment cleanup)
internal/router/router.go:
- Add ProcessingIssuesHandler field to router Config struct
- Reformat Config struct for better field alignment
This enables the processing issues API endpoints for listing and getting
statistics about issues within libraries, integrated with the admin UI.
Fix ResolveProcessingIssue and DeleteProcessingIssue methods to use proper
parameter structs instead of individual arguments.
Changes:
- ResolveProcessingIssue: Use database.ResolveProcessingIssueParams struct
with ID and MediaItemID fields instead of separate arguments
- DeleteProcessingIssue: Wrap issueID in pgtype.UUID struct
- Use map[string]any instead of map[string]interface{} for JSON responses
These changes align with the sqlc-generated database interface and ensure
type-safe parameter passing to the database layer.
Add admin_processing_issues_templ.go template for managing processing issues
in the admin dashboard. This template provides:
- List view of all processing issues with filtering by severity
- Issue details display (file path, error type, description)
- Actions to resolve or dismiss issues
- Integration with the ProcessingIssuesHandler API endpoints
This UI enables administrators to monitor and address processing errors that
occur during media scanning and import workflows.
Add ProcessingIssueData and IssueStats types to templates/types.go for use
in the processing issues management UI. These types support:
- ProcessingIssueData: Individual issue details including ID, media item,
file path, format, issue type, severity, and timestamps
- IssueStats: Aggregated counts of issues by severity (error, warning, info)
These types enable the admin UI to display processing issues from the database
and provide statistics for the issues dashboard.
Add Go package documentation comments to clarify the purpose and scope of:
- internal/handlers/: HTTP request/response handlers for authentication,
libraries, media items, reading, collections, dashboards, devices,
analytics, and system features
- internal/services/: Core business logic layer including media scanning,
library management, search, analytics, and conversion services
These doc comments improve code discoverability and help developers understand
the architectural separation between HTTP handling (handlers) and business
logic (services).
Remove READER_REFACTOR_MODULARIZATION_AND_PAGINATION.md as the modularization
and pagination refactoring has been completed and integrated into the codebase.
This document outlined:
- Modular reader architecture by format (reflowable, pdf, comic, manga)
- Page-based pagination using word count estimation
- CFI-based progress tracking for reflowable formats
- Format-agnostic UI components
The implementation has been completed, so this design document is no longer needed.
Added comprehensive integration tests for the new processing issues API
endpoints that track EPUB format mismatches in manga/comics libraries.
Test Coverage:
- Authentication & authorization (no auth, invalid auth, non-admin, admin)
- Input validation (malformed UUIDs, path traversal, SQL injection attempts)
- Response structure validation (fields, types, content-type)
- Cross-library isolation (ensures issues don't leak between libraries)
- All library types (ebooks, comics, manga, audiobooks)
- Edge cases and error conditions
Endpoints Tested:
- GET /api/libraries/:id/issues/list - Lists unresolved processing issues
- GET /api/libraries/:id/issues/stats - Returns error/warning/info counts
Test Implementation:
- 522 lines, 9 test functions, 30+ subtests
- Uses setupTestServer() helper for server setup
- Uses setupDeviceTest() helper for library creation
- Follows PROJECT_GUIDELINES.md requirements
- Table-driven tests with t.Run() for comprehensive coverage
- Tests all three user contexts: no user, regular user, admin
This ensures the processing issues feature is properly tested before
integration with the media scanner service.

- Support tracking format mismatches and other processing problems
- Unique constraint on media_item_id and issue_type to prevent duplicates
Remove unused Epubcfi and Percentage fields from UpdateReadingProgressParams
struct to align with the new foliate-js based reader implementation.
The foliate-js library handles CFI tracking and percentage calculation
internally, so these parameters are no longer needed in the update API.
The reader now relies on foliate-js's built-in progress tracking mechanisms.
This change aligns the database layer with the foliate-js integration completed
in commit c7a9098 (feat: Replace foliate-js submodule with npm git dependency).
Changes:
- Remove Epubcfi field from UpdateReadingProgressParams struct
- Remove Percentage field from UpdateReadingProgressParams struct
- UpdateReadingProgress function now uses simplified parameter set
This document provides a complete, phased implementation plan for:
- Enabling manga EPUBs in manga library (not just CBZ/CBR)
- Detecting fixed-layout EPUBs vs reflowable EPUBs
- Processing issue tracking for format mismatches
- Universal panel detection for manga and comics libraries
- Smart panel detection that works for PDF comics but not PDF ebooks
Key features:
- All changes follow existing code patterns with exact line numbers
- 9 implementation phases in correct dependency order
- Code-around context for every change (before/after)
- Testing checklist and rollback plan
- Database schema changes, scanner enhancements, new handlers, frontend updates
Panel detection logic:
- Manga library + fixed_layout/comic_archive → panel detection ON
- Comics library + fixed_layout/comic_archive → panel detection ON
- Ebooks library + any format → panel detection OFF
- Comics library + PDF → panel detection ON
- Ebooks library + PDF → panel detection OFF
Implementation addresses the constraint that manga EPUBs live in /manga/
directory physically but must be filtered to only show fixed-layout EPUBs
in the manga library (not reflowable novels).
This is a planning document only - no code changes yet.
Migrate from git submodule to npm package management for better
developer experience and simplified deployment.
Changes:
- Add @bookhoard/foliate-js from GitHub fork
(john-okeefe/foliate-js#bookhoard-panel-detection)
- Update vite alias to point to node_modules instead of vendor
- Delete .gitmodules (no submodules tracked)
- Remove scripts/setup-git-hooks.sh (no longer needed)
- Delete web/vendor/foliate-js/ submodule directory
- Remove sc-commit git alias (submodule-specific)
Benefits:
- Standard npm workflow (npm install / npm update)
- No authentication issues for end users (public GitHub)
- Simpler deployment (npm ci in containers)
- foliate-js protected in node_modules (AI won't rewrite)
- Independent project management
- Cleaner git history
Technical details:
- Import remains unchanged: import "foliate-js/view.js"
- Vite alias maps "foliate-js" to "/node_modules/@bookhoard/foliate-js"
- Build verified working (reader.js includes foliate-js)
- Package installed from git branch: bookhoard-panel-detection
- Add chmod +x to ensure pre-push hook is executable after creation
- Add global git alias 'sc-commit' for committing to all submodules at once
- Improve user feedback with detailed explanation of installed components
- Better code organization with clearer comments
This makes the setup script more robust by ensuring the hook has proper permissions and provides a convenient command for bulk submodule commits.
This script installs a pre-push hook that prevents pushing commits when submodules have uncommitted changes, helping avoid accidental commits with dirty submodule states.
The hook checks all submodules for uncommitted changes before allowing a push, protecting against pushing incomplete work that includes submodule modifications.
- Add web/static/*.mjs to ignore compiled JavaScript modules
- Add web/static/text_layer_builder*.css for PDF.js text layer CSS files
- Add web/static/annotation_layer_builder*.css for PDF.js annotation layer CSS
These files are generated during the PDF.js build process and should not be tracked in version control.
Create minimal Alpine.js integration for foliate-js reader. This file
serves as the entry point that imports foliate-js and provides basic
navigation controls.
Implementation:
1. Import foliate-js/view.js:
- Registers <foliate-view> custom element globally
- Makes foliate reader functional when element is added to DOM
- No explicit EPUB imports needed (foliate detects format automatically)
2. Alpine.js integration:
- Create readerShell data object for UI state management
- Provide nextPage() and previousPage() methods for button controls
- Methods access <foliate-view> custom element's API (next(), prev())
- Simple, functional approach (no OOP, follows project guidelines)
3. Init placeholder:
- initReader() method for future initialization logic
- Currently just logs for debugging
- Will be extended with theme switching, progress sync, etc.
Design Choices:
- Follow project guidelines: No classes, functional/procedural style
- Use Alpine.js for UI state (consistent with rest of application)
- Defer book loading to foliate's internal format detection
- Minimal footprint: Only what's needed to make <foliate-view> work
Next Steps (Future Commits):
- Theme switching logic (apply CSS custom properties)
- Progress sync to API (listen to foliate's relocate event)
- Book loading integration (open book path, handle CFI locations)
- Settings persistence (save theme, font, spacing preferences)
File: web/src/reader/reader.ts (31 lines)
- Clean separation: Foliate handles rendering, Alpine handles UI state
- Type-safe with @ts-ignore for foliate custom element API access
Add comprehensive reading theme system with 18 themes organized into 5 categories.
All themes include light and dark mode variants, optimized for readability and
eye comfort during long reading sessions.
Theme Categories:
1. Classic Reading (6 themes)
- Light, Paper, Sepia, Parchment, Warm, Candlelight
- Time-tested, comfortable for general reading
2. Sky & Atmosphere (4 themes)
- Azure, Sky, Arctic, Frost
- Open, airy, contemplative feel with blue tones
3. Sunset & Warmth (3 themes)
- Dusk, Sunset, Twilight
- Warm, energizing colors for evening reading
4. Nature & Earth (3 themes)
- Forest, Moss, Slate
- Grounded, natural, calming greens and grays
5. High Performance (2 themes)
- OLED, Solarized
- Optimized for specific use cases (battery saving, precision design)
Theme Features:
- All themes pass WCAG AAA contrast standards (7:1 ratio)
- Each theme has light and dark mode variants
- CSS custom properties for dynamic theme switching
- Optimized color temperatures for different lighting conditions
- Inspired by best practices from e-readers (Kindle, Kobo) and community projects (Grimmory)
Design Principles:
- Readability first: Avoid pure black on pure white (causes eye strain)
- Color temperature: Warm tones for evening, cool tones for daytime focus
- Typography support: Works seamlessly with 9 bundled libre fonts
- Progressive enhancement: Themes work without JavaScript
File: web/static/foliate-themes.css (301 lines)
- CSS custom properties for each theme variant
- Typography base styles (font-family, font-size, line-height, margins)
- Link, selection, and image handling styles
- Orphan/widow prevention for better text flow
Update Vite configuration to support foliate-js library integration:
1. Add import alias for foliate-js:
- Maps 'foliate-js' imports to web/vendor/foliate-js submodule
- Allows clean imports: import { View } from 'foliate-js/view.js'
2. Update build target to ESNext:
- Change from 'es2020' to 'esnext' to support top-level await
- Required by foliate-js pdf.js which uses top-level await
- ES2022+ support is excellent in all modern browsers (Chrome 112+, Firefox 115+, Safari 16.4+)
These changes enable Vite to bundle foliate-js into reader.js without
requiring a separate build step for the library.
Remove 60+ files from the old reader implementation that relied on
CSS columns pagination, which was fundamentally broken. This includes:
- Comic/Manga format handlers (panel detection, reading direction)
- PDF rendering, bookmarks, annotations, outlines
- Reflowable content pagination (EPUB, FB2, TXT, HTML parsers)
- UI components (gestures, keyboard shortcuts, panel dock system)
- Core navigation and state management
The old implementation used CSS columns for EPUB pagination, but this
approach is fundamentally incompatible with horizontal book layouts
because CSS columns fill vertically first, then wrap horizontally.
This causes only 1 column to be created instead of the expected 92+.
This cleanup prepares the codebase for foliate-js integration, which
uses JavaScript-driven pagination with CFI-based positioning that
actually works for book reading.
Files removed:
- formats/: comic/, manga/, pdf/, reflowable/ (65 files)
- parsers/: EPUB, FB2, TXT, HTML (4 files)
- ui/: gestures, keyboard shortcuts, panel dock, progress tracker (8 files)
- core/: parser-manager, reader-navigation, reader-services, reader-state (4 files)
- reader-shell.ts: Main reader orchestrator (565 lines)
Total: 9,361 lines removed
Reader functionality will be restored via foliate-js integration.
