Refactor app from novel reader to Pomodoro timer by AngKS · Pull Request #1 · even-realities/EH-InNovel

AngKS · 2026-02-14T18:39:36Z

Summary

This PR completely refactors the application from an e-book reader (InNovel) to a Pomodoro timer application. The core business logic, UI components, and data models have been replaced to support timer functionality instead of book reading.

Key Changes

Core State Management

Replaced book-related state (currentReadingBookId, readingFragments, etc.) with timer state (TimerState enum, remainingSeconds, selectedPreset)
Simplified AppUiState to focus on timer display: removed books, isFullScreenReading, audioEventDisplayLines
Added TimerPreset enum with predefined durations (5, 15, 25, 45 minutes)

Timer Logic

Implemented startTimer(), pauseTimer(), and resetTimer() functions with coroutine-based tick mechanism
Added selectPreset() to allow users to choose timer duration
Integrated timer display updates to glasses via pushTimerToGlasses() and updateTimerDisplay()
Timer state machine: IDLE → RUNNING → PAUSED/FINISHED

UI Components

Removed: BookItem, TextImageView, TextAudioView, ReadingDialog components
Added: TimerDisplay, TimerControls, PresetSelector, TimerHeaderCard (renamed from UserBookshelfCard)
Updated AppScreen to display timer controls and preset selection instead of book list
Simplified header to show user info and device status only

Data Models

Replaced BookModel and BookChapterModel with TimerPreset enum
Removed book-related event handlers (handleListItemEvent, handleTextItemEvent, handleSysItemEvent)
Removed audio event display logic

SDK Integration

Removed book loading from JSON (loadBooksFromJson(), defaultBooks())
Removed chapter reading functions (startReadingBook(), fullScreenReading(), updateChapterInfo())
Kept device status and EvenHubEvent observers but removed book-specific event handling
Added timer push to glasses display on initialization

Project Configuration

Updated app.json: package ID and app name changed to Pomodoro Timer
Updated settings.gradle.kts: root project name changed to PomodoroTimer
Updated HTML title and resources references
Added GitHub Actions workflow for building JS and Wasm bundles

Implementation Details

Timer uses Job and delay(1000) for 1-second ticks
Preset selector allows changing duration only when timer is IDLE
Timer state persists across pause/resume cycles
Display updates to glasses synchronized with timer state changes

- Add 5/15/30 min timer presets selectable via ring scroll (ListContainer) - Timer countdown displayed on glasses via TextContainer with 1s updates - Double-click toggles start/pause/reset via SysItemEvent handling - Compose UI: TimerDisplay, PresetSelector, TimerControls, TimerHeaderCard - GitHub Actions workflow for JS and Wasm production builds - Remove novel reader models, views, and books.json data https://claude.ai/code/session_01MTm41KGmtgFhjhGCWdRDjU

Pull request overview

This PR represents a complete application refactor from an e-book reader (InNovel) to a Pomodoro timer application. The transformation replaces all book-related functionality with timer-specific features while maintaining the core SDK integration for Even Realities glasses.

Changes:

Replaced book management (BookModel, chapters) with timer presets (5/15/30 minutes) and timer state machine (IDLE, RUNNING, PAUSED, FINISHED)
Refactored UI from book list/reading views to timer display with preset selector and control buttons
Updated glasses SDK integration to display timer and presets instead of books and chapters, with double-click gestures controlling timer state transitions

+    private fun handleListItemEvent(event: ListItemEvent) {
+        val index = event.currentSelectItemIndex ?: return
+        val presets = TimerPreset.values()
+        if (index in presets.indices) {
+            selectPreset(presets[index])
+        }
+    }


When a list item event is received (user selects a preset from the glasses), the selectPreset function is called which will silently fail if the timer is RUNNING. This could confuse users who try to change presets via the glasses while the timer is running. Consider handling this case explicitly to provide feedback or prevent the selection in the UI.

+    fun selectPreset(preset: TimerPreset) {
+        if (uiState.timerState == TimerState.RUNNING) return
        uiState = uiState.copy(
-            audioEventDisplayLines = (uiState.audioEventDisplayLines + line).takeLast(maxAudioEventDisplayLines)
+            selectedPreset = preset,
+            remainingSeconds = preset.seconds,
+            timerState = TimerState.IDLE,
        )
+        coroutineScope.launch { pushTimerToGlasses() }
    }


The selectPreset function only blocks changes when the timer is RUNNING but allows changes when PAUSED. However, when PAUSED, changing the preset will reset the timer to IDLE and reset remainingSeconds, losing any progress. This behavior may be unexpected for users. Consider either blocking preset changes when PAUSED or clearly documenting this behavior.

The file is renamed from BookModel.kt but still has that filename. It should be renamed to TimerPreset.kt or TimerModels.kt to accurately reflect its new purpose and content.

+        unsubscribeEvenHubEvent?.invoke()
+        unsubscribeEvenHubEvent = null
    }


The dispose() function is defined but never called. This means that when the app exits, the observers (unsubscribeDeviceStatus and unsubscribeEvenHubEvent) are not cleaned up, potentially causing memory leaks. Consider calling dispose() in a DisposableEffect or OnDispose callback in the App composable, or ensure it's called when exitTimer() is invoked.

Magic numbers are used throughout the glasses display layout (e.g., width: 130, height: 235, xPosition: 140, borderColor: 13, etc.). These values lack context and make the code harder to understand and maintain. Consider using named constants with descriptive names to explain what these dimensions and colors represent.

The PR description mentions presets of 5, 15, 25, and 45 minutes, but the actual implementation only includes 5, 15, and 30 minutes. This discrepancy should be addressed - either update the code to match the description, or update the description to match the implementation.

The package name remains "com.fzfstudio.eh.innovel" throughout the codebase but the application has been completely refactored from a novel reader to a Pomodoro timer. While this is outside the diff, it creates inconsistency - the package_id in app.json is correctly updated to "com.fzfstudio.pomodoro", but the source code package names don't match. Consider renaming the package structure to match the new application purpose.

The selectPreset function changes the timer state to IDLE even when it's already IDLE. While harmless, this triggers unnecessary state updates and coroutine launches. Consider only updating state if the preset actually changed.

+                )


The containerID values (1 and 2) and container names ("presets", "timer") are hardcoded in multiple locations. If these need to change, updates must be made in pushTimerToGlasses() and updateTimerDisplay(). Consider defining these as constants at the class level to improve maintainability.

+                updateTimerDisplay()


The updateTimerDisplay() function is called on every tick (every second) during timer operation. This creates SDK calls every second, which may impact performance and battery life on the glasses. Consider batching updates or only updating at key intervals, unless per-second updates are a hard requirement for the glasses display.
