Qamar KMP Libraries

Multiplatform Quran stack built from the legacy QamarOld assets. Modules:

quran-core: SQLDelight schema + bundled Arabic text/page map (quran.db, arabic.json, quran_paged.json) and platform drivers.
quran-transliteration: Loads transliteration JSON (KK/EN/RU) with JsonTransliterationProvider.
quran-translations: Translation metadata + manager contracts (downloads TBD).
quran-api: Public QuranApi facade on top of the core DB, transliteration, and translations.
quran-search: Thin search helper delegating to QuranApi.
quran-audio: Reciters list, audio URL resolution (config/templates), and Quran-Audio Project pure helpers for apps that store reciter by name/address (see below).
quran-tajweed: Tajweed (recitation rules) detection: input Arabic verse text, output List<TajweedSpan> (start, end, rule). Platform-agnostic; use with verse text from QuranApi or any source. Rules: MAD, GHUNNA, QALQALA, IQLAB, IDGHAM, IKHFA, HAMZAT_WASL, MAD_HEY, ONE_MAD, MADDAH.
prayer-core: Multiplatform prayer time calculation engine (ported from QamarOld). Works on Android, iOS, JS, Desktop. Supports multiple calculation methods (MWL, ISNA, Egypt, Makkah, etc.), Asr (Shafii/Hanafi), high-latitude adjustments, and timezone resolution (device default or Android CSV-based).

Installation

Add the dependencies to your build.gradle.kts:

dependencies {
    // Core database and models
    implementation("io.github.maqsats:quran-core:1.0.0")
    
    // Public API
    implementation("io.github.maqsats:quran-api:1.0.0")
    
    // Translations
    implementation("io.github.maqsats:quran-translations:1.0.0")
    
    // Transliteration
    implementation("io.github.maqsats:quran-transliteration:1.0.0")
    
    // Search
    implementation("io.github.maqsats:quran-search:1.0.0")
    
    // Audio (reciters, URL resolution, Quran-Audio Project pure helpers)
    implementation("io.github.maqsats:quran-audio:1.0.0")
    
    // Tajweed (recitation rules: spans for coloring)
    implementation("io.github.maqsats:quran-tajweed:1.0.0")
    
    // Prayer times (KMP: Android, iOS, JS, Desktop)
    implementation("io.github.maqsats:prayer-core:1.0.0")
}

For Kotlin Multiplatform projects, add the appropriate platform-specific dependencies as needed.

Data generation (already run)

Source data comes from /Users/maqsat/StudioProjects/QamarOld/app/src/main:

Arabic & transliterations: res/values/arabic.xml, translit*.xml
Page map: assets/databases/qurankz.db
Translation metadata: assets/translations.json

Regenerate artifacts if the source changes:

cd /Users/maqsat/StudioProjects/qamar-kmp-libraries
python3 tools/generate_quran_db.py
# Copies are expected at:
# quran-core/src/commonMain/resources/{databases/quran.db,arabic.json,quran_paged.json}
# quran-transliteration/src/commonMain/resources/translit_{en,ru,kk}.json
# quran-translations/src/commonMain/resources/translations.json

Quick usage

// Platform-side: create driver (Android requires Context)
val driver = DatabaseFactory(context).createDriver()
val db = QuranDatabase(driver)

val api = DefaultQuranApi(
    database = db,
    translationManager = null, // wire in later
    transliterationProvider = JsonTransliterationProvider(context)
)

val verse1 = api.getVerse(1, 1)
val page1 = api.getPage(1)
val search = api.searchArabic("بسم")

// Tajweed: get spans for coloring verse text (use verse.arabicText from API)
verse1?.let { v -> TajweedApi.getTajweedSpans(v.arabicText) }
// Platform applies color per span.rule (MAD, GHUNNA, QALQALA, IQLAB, IDGHAM, IKHFA, etc.)

Passing `platformContext`

Pass the same platformContext to all resource/database-backed components:

DatabaseFactory(platformContext)
JsonTransliterationProvider(platformContext)
TranslationMetadataSource(platformContext)

Target	What to pass	Notes
Android	`context.applicationContext`	Required. `DatabaseFactory` throws if value is not an Android `Context`.
iOS	`null`	Current implementation reads from `NSBundle.mainBundle`; `platformContext` is not used.
Desktop (JVM)	`null`	Current implementation loads bundled resources via classpath; `platformContext` is not used.
JS (Browser/Node)	`null`	Current implementation does not use `platformContext`.

Recommended shared initializer:

suspend fun createQuranApi(platformContext: Any?): QuranApi {
    val driver = DatabaseFactory(platformContext).createDriver()
    val db = QuranDatabase(driver)
    val transliteration = JsonTransliterationProvider(platformContext)

    return DefaultQuranApi(
        database = db,
        translationManager = null,
        transliterationProvider = transliteration
    )
}

Usage per target:

// Android
val api = createQuranApi(context.applicationContext)

// iOS / Desktop / JS
val api = createQuranApi(null)

Tajweed (quran-tajweed)

Input: Arabic verse string (e.g. from QuranApi.getVerse(1, 1)?.arabicText). Output: List<TajweedSpan>(start, end, rule). Apply your own colors/spans per TajweedRule on Android (ForegroundColorSpan), Compose (SpanStyle), or iOS (NSAttributedString).

val verse = api.getVerse(1, 1)?.arabicText ?: ""
val spans = TajweedApi.getTajweedSpans(verse)
spans.forEach { (start, end, rule) -> /* apply color for rule */ }

Prayer times (prayer-core)

Use a platform-specific TimeZoneProvider (all use the device's default time zone):

// Android / iOS / JS / Desktop: device timezone
val tzProvider = DefaultTimeZoneProvider() // or AndroidTimeZoneProvider() / IosTimeZoneProvider() / JsTimeZoneProvider() / JvmTimeZoneProvider()

val api = PrayerTimeApi(timeZoneProvider = tzProvider)
api.withCalculator { calculationMethod = CalculationMethod.MWL; timeFormat = TimeFormat.TIME_24 }

val date = DateComponents(2025, 6, 15)
val times = api.getPrayerTimes(date, latitude = 51.5074, longitude = -0.1278)
// times.fajr, times.sunrise, times.dhuhr, times.asr, times.sunset, times.maghrib, times.isha

val monthTimes = api.getPrayerTimesForMonth(2025, 6, 51.5074, -0.1278)

On Android/iOS/JS/Desktop, use DateComponents(year, month, day) (1-based month). On JVM/Android you can use calendar.toDateComponents() from the platform extension.

Notes / TODO

JS resource loading is stubbed; wire a bundler/loader for arabic.json, quran_paged.json, and transliteration JSON.
Translation downloads/storage are contract-only; needs implementation backed by the metadata + downloaded DB files.
iOS resource loading assumes the bundled files are retained in the app target.
