# Komikku – AI Agent Guide
|
||
|
||
Komikku is an Android manga reader (min SDK 26, target SDK 36, JVM 17 / Kotlin) forked from **Mihon** + **TachiyomiSY**. Stack: Jetpack Compose + Material3, Voyager navigation, SQLDelight, Injekt DI. `applicationId`: `app.komikku`.
|
||
|
||

|
||
|
||
## Module layout
|
||
|
||
| Module | Purpose |
|
||
|--------|---------|
|
||
| `app/` | UI (`eu.kanade.*`, `exh/`, `mihon/`), DI, workers, build variants |
|
||
| `domain/` | Use cases in `…/interactor/` (e.g. `GetManga`), models, repo interfaces |
|
||
| `data/` | SQLDelight DB, `*RepositoryImpl` (`tachiyomi.data.*`) |
|
||
| `core:common/` | Network (OkHttp), security, storage, shared utils |
|
||
| `core:archive/` | CBZ/archive reading with optional encryption |
|
||
| `core-metadata/` | Comic-info metadata parsing |
|
||
| `source-api/` / `source-local/` | Extension `Source` API + local source |
|
||
| `presentation-core/` | Shared Compose components |
|
||
| `presentation-widget/` | Home-screen Glance widget |
|
||
| `i18n/` | Mihon strings → `MR` (moko-resources) |
|
||
| `i18n-kmk/` | Komikku strings → `KMR` |
|
||
| `i18n-sy/` | TachiyomiSY strings → `SYMR` |
|
||
| `flagkit/` | Country-flag drawables |
|
||
| `telemetry/` | Firebase/Crashlytics (noop unless `-Pinclude-telemetry`) |
|
||
| `macrobenchmark/` | Macrobenchmark tests |
|
||
|
||
Dependency flow: `app` → `domain` → `source-api`; `data` implements `domain` repos.
|
||
|
||
Version catalogs: `gradle/libs.versions.toml`, `kotlinx.versions.toml`, `androidx.versions.toml`, `compose.versions.toml`, `sy.versions.toml`.
|
||

|
||
|
||
## Architecture
|
||
|
||
**DI** – `uy.kohesive.injekt` (not Hilt). Register in `AppModule.kt`, `DomainModule.kt`, `KMKDomainModule.kt`, `SYDomainModule.kt` via `addSingleton` / `addSingletonFactory`. Resolve with `Injekt.get<T>()` or `injectLazy<T>()`.
|
||
|
||
**UI & navigation** – [Voyager](https://voyager.adriel.cafe/): `Screen` in `eu.kanade.tachiyomi.ui.*`, composables in `eu.kanade.presentation.*`. Base type: `eu.kanade.presentation.util.Screen`. State via `rememberScreenModel { … }`; most models extend `StateScreenModel<State>` or bases like `SearchScreenModel`; some use plain `ScreenModel`. Prefer `screenModelScope` and `ioCoroutineScope`; use `launchIO` / `withIOContext` from `tachiyomi.core.common.util.lang`. `rememberCoroutineScope()` is fine in Compose; long-lived services may use their own `CoroutineScope`.
|
||
|
||
**Activities (not Voyager)** – `MainActivity` (shell), `ReaderActivity` + `ReaderViewModel`, `WebViewActivity`, `UnlockActivity`, OAuth login activities, `DeepLinkActivity`. Reader: `ReaderActivity.newIntent(context, mangaId, chapterId)`. Web: both `WebViewScreen` (Voyager) and `WebViewActivity.newIntent(...)`.
|
||
|
||
Example: `DeepLinkScreen` + `DeepLinkScreenModel` in `app/src/main/java/eu/kanade/tachiyomi/ui/deeplink/`.
|
||
|
||
**Domain / data** – One class per operation under `domain/…/interactor/` (verb names, not `*Interactor` suffix). Also `app/src/main/java/eu/kanade/domain/…/interactor/` for app-specific cases. Wire repos in `eu.kanade.domain.DomainModule.kt` (+ `KMKDomainModule`, `SYDomainModule`).
|
||
|
||
**Database** – SQLDelight in `data/src/main/sqldelight/tachiyomi/` (`.sq` queries, `migrations/*.sqm`). After schema changes add a new `.sqm` and often `// KMK` blocks in `.sq` / mappers. Regenerate: `./gradlew :data:generateSqlDelightInterface` (or any compile that touches `:data`).
|
||
|
||
**App preference migrations** – `app/src/main/java/mihon/core/migration/migrations/` (`mihon.core.migration.Migration`).
|
||
|
||
**Images** – Coil 3 (`coil3.*`, `context.imageLoader`). No Glide/Picasso.

|
||
## Komikku-specific work
|
||
|
||
- New user-facing strings: **`KMR`** in `i18n-kmk/src/commonMain/moko-resources/base/`. Shared/upstream: **`MR`** (`i18n`). SY-only: **`SYMR`** (`i18n-sy`).
|
||
- Do not edit locale `strings.xml` in `i18n/` or `i18n-sy/` except when syncing upstream; translations via [Weblate](https://hosted.weblate.org/engage/komikku-app/).
|
||
- Komikku code/DI: search `// KMK` (e.g. `KMKDomainModule`, `HideCategory`, library-update errors).
|
||
- Prefs: `eu.kanade.domain.*.service.*Preferences` (e.g. `SourcePreferences.relatedMangas()`).
|
||
|
||
---
|
||
|
||
## Extensions & sources
|
||
|
||
- Catalog sources: installable APK extensions (not in this repo).
|
||
- In-repo: delegated sources and metadata in `exh/` (E-Hentai, NHentai, MangaDex, `exh/recs/`).
|
||
- `source-api`: `eu.kanade.tachiyomi.source.*` — avoid breaking extension ABI.
|
||
|
||
---
|
||
|
||
## Build & CI
|
||
|
||
Build types: `debug` (`.dev`), `release`, `releaseTest` (`.rt`), `foss` (`.foss`), `preview` (`.beta`, CI default), `benchmark`.
|
||
|
||
Gradle `-P` flags (`buildSrc/.../BuildConfig.kt`):
|
||
|
||
| Flag | Effect |
|
||
|------|--------|
|
||
| `include-telemetry` | Firebase Analytics + Crashlytics |
|
||
| `enable-updater` | In-app update checker |
|
||
| `disable-code-shrink` | Skip R8 minification |
|
||
| `include-dependency-info` | Dependency metadata in APK |
|
||
|
||
```bash
|
||
./gradlew spotlessApply # format (CI: spotlessCheck)
|
||
./gradlew assemblePreview # main CI/dev APK
|
||
./gradlew assemblePreview -Pinclude-telemetry -Penable-updater # full upstream CI build
|
||
./gradlew testReleaseUnitTest # CI unit tests (or ./gradlew test for all modules)
|
||
./gradlew installDebug # device install
|
||
./gradlew :data:generateSqlDelightInterface # after .sq / .sqm changes
|
||
```
|
||
|
||
JDK **17**.
|
||
|

|
||
|
||
## Fork-origin markers
|
||
|
||
Preserve inline blocks when editing:
|
||
|
||
```kotlin
|
||
// KMK --> … // KMK <-- Komikku
|
||
// SY --> … // SY <-- TachiyomiSY
|
||
// EXH --> … // EXH <-- E-Hentai / exh (existing); prefer KMK for new Komikku-only code
|
||
```
|
||
|
||
Package roots: `eu.kanade.tachiyomi.*` (legacy UI), `tachiyomi.*` (domain/data), `mihon.*` (Mihon upstream), `exh.*` (enhanced sources).
|
||
|
||
---
|
||
|
||
## Tests
|
||
|
||
- Unit tests: `domain/src/test/`; app: `app/src/test/.../MigratorTest.kt`. No broad UI test suite.
|
||
|
||
---
|
||
|
||
## Conventions
|
||
|
||
- **Logging** – Prefer `xLogE()` / `xLog()` helpers from `exh.log` for Komikku code, Mihon uses `logcat { }` from `tachiyomi.core.common.util.system`. Avoid raw `android.util.Log`.
|
||
- **Formatting** – Spotless + ktlint (`buildSrc/.../mihon.code.lint.gradle.kts`).
|
||
- **Fork edits** – New Komikku features inside `// KMK` islands; keep `// SY` / `// EXH` blocks intact when merging upstream.
