Development Guidelines & Coding Standards - -### A. UI Development (Jetpack Compose) -- **Material 3:** The app uses Material 3. -- **Strings:** MUST use the **Compose Multiplatform Resource** library in `core:resources` (`stringResource(Res.string.your_key)`). For ViewModels or non-composable Coroutines, use the asynchronous `getStringSuspend(Res.string.your_key)`. NEVER use hardcoded strings, and NEVER use the blocking `getString()` in a coroutine. -- **Dialogs:** Use centralized components in `core:ui` (e.g., `MeshtasticResourceDialog`). -- **Alerts:** Use `AlertHost(alertManager)` from `core:ui/commonMain` in each platform host shell (`Main.kt`, `DesktopMainScreen.kt`). For global responses like traceroute and firmware validation, use the specialized common handlers: `TracerouteAlertHandler(uiViewModel)` and `FirmwareVersionCheck(uiViewModel)`. Do NOT duplicate inline alert-rendering logic or trigger alerts directly during composition. For shared QR/contact dialogs, use the `SharedDialogs(uiViewModel)` composable. -- **Placeholders:** For desktop/JVM features not yet implemented, use `PlaceholderScreen(name)` from `core:ui/commonMain`. Do NOT define inline placeholder composables in feature modules. -- **Theme Picker:** Use `ThemePickerDialog` and `ThemeOption` from `feature:settings/commonMain`. Do NOT duplicate the theme dialog or enum in platform-specific source sets. -- **Adaptive Layouts:** Use `currentWindowAdaptiveInfo(supportLargeAndXLargeWidth = true)` to support the 2026 Desktop Experience breakpoints. Prioritize **higher information density** and mouse-precision interactions for Desktop and External Display (Android 16 QPR3) targets. **Investigate 3-pane "Power User" scenes** (e.g., Node List + Detail + Map/Charts) using Navigation 3 Scenes, `extraPane()`, and draggable dividers (`VerticalDragHandle` + `paneExpansionState`) for widths ≥ 1200dp. -- **Platform/Flavor UI:** Inject platform-specific behavior (e.g., map providers) via `CompositionLocal` from `app`. - -### B. Logic & Data Layer -- **KMP Focus:** All business logic must reside in `commonMain` of the respective `core` module. -- **Platform purity:** Never import `java.*` or `android.*` in `commonMain`. Use KMP alternatives: - - `java.util.Locale` → Kotlin `uppercase()` / `lowercase()` or `expect`/`actual`. - - `java.util.concurrent.ConcurrentHashMap` → `atomicfu` or `Mutex`-guarded `mutableMapOf()`. - - `java.util.concurrent.locks.*` → `kotlinx.coroutines.sync.Mutex`. - - `java.io.*` → Okio (`BufferedSource`/`BufferedSink`). - - `kotlinx.coroutines.Dispatchers.IO` → `org.meshtastic.core.common.util.ioDispatcher` (expect/actual). -- **Shared helpers over duplicated lambdas:** When `androidMain` and `jvmMain` contain identical pure-Kotlin logic (formatting, action dispatch, validation), extract it to a function in `commonMain`. Examples: `formatLogsTo()` in `feature:settings`, `handleNodeAction()` in `feature:node`, `findNodeByNameSuffix()` in `feature:connections`, `MeshtasticAppShell` in `core:ui/commonMain`, and `BaseRadioTransportFactory` in `core:network/commonMain`. -- **KMP file naming:** In KMP modules, `commonMain` and platform source sets (`androidMain`, `jvmMain`) share the same package namespace. If both contain a file with the same name (e.g., `LogExporter.kt`), the Kotlin/JVM compiler will produce a duplicate class error. Use distinct filenames: keep the `expect` declaration in `LogExporter.kt` and put shared helpers in a separate file like `LogFormatter.kt`. -- **`jvmAndroidMain` source set:** Modules that share JVM-specific code between Android and Desktop apply the `meshtastic.kmp.jvm.android` convention plugin. This creates a `jvmAndroidMain` source set via Kotlin's hierarchy template API. Used in `core:common`, `core:model`, `core:data`, `core:network`, and `core:ui`. -- **Hierarchy template first:** Prefer Kotlin's default hierarchy template and convention plugins over manual `dependsOn(...)` graphs. Manual source-set wiring should be reserved for cases the template cannot model. -- **`expect`/`actual` restraint:** Prefer interfaces + DI for platform capabilities; use `expect`/`actual` for small unavoidable platform primitives. Avoid broad expect/actual class hierarchies when an interface-based boundary is sufficient. -- **Feature navigation graphs:** Feature modules export Navigation 3 graph functions as extension functions on `EntryProviderScope` in `commonMain` (e.g., `fun EntryProviderScope.settingsGraph(backStack: NavBackStack)`). Host shells (`app`, `desktop`) assemble these into a single `entryProvider` block. Do NOT define navigation graphs in platform-specific source sets. -- **Concurrency:** Use Kotlin Coroutines and Flow. -- **Dependency Injection:** Use **Koin Annotations** with the K2 compiler plugin (`koin-plugin` in version catalog). The `koin-annotations` library version is unified with `koin-core` (both use `version.ref = "koin"`). The `KoinConventionPlugin` uses the typed `KoinGradleExtension` to configure the K2 plugin (e.g., `compileSafety.set(false)`). Keep root graph assembly in `app`. -- **ViewModels:** Follow the MVI/UDF pattern. Use the multiplatform `androidx.lifecycle.ViewModel` in `commonMain`. Both `app` and `desktop` use `MeshtasticNavDisplay` from `core:ui/commonMain`, which configures `ViewModelStoreNavEntryDecorator` + `SaveableStateHolderNavEntryDecorator`. ViewModels obtained via `koinViewModel()` inside `entry` blocks are scoped to the entry's backstack lifetime and cleared on pop. -- **Navigation host:** Use `MeshtasticNavDisplay` from `core:ui/commonMain` instead of calling `NavDisplay` directly. It provides entry-scoped ViewModel decoration, `DialogSceneStrategy` for dialog entries, and a shared 350 ms crossfade transition. Host modules (`app`, `desktop`) should NOT configure `entryDecorators`, `sceneStrategies`, or `transitionSpec` themselves. -- **BLE:** All Bluetooth communication must route through `core:ble` using Kable. -- **Networking:** Pure **Ktor** — no OkHttp anywhere. Engines: `ktor-client-android` for Android, `ktor-client-java` for desktop/JVM. Use Ktor `Logging` plugin for HTTP debug logging (not OkHttp interceptors). `HttpClient` is provided via Koin in `app/di/NetworkModule` and `core:network/di/CoreNetworkAndroidModule`. -- **Image Loading (Coil):** Use `coil-network-ktor3` with `KtorNetworkFetcherFactory` on **all** platforms. `ImageLoader` is configured in host modules only (`app` via Koin `@Single`, `desktop` via `setSingletonImageLoaderFactory`). Feature modules depend only on `libs.coil` (coil-compose) for `AsyncImage` — never add `coil-network-*` or `coil-svg` to feature modules. -- **Dependencies:** Check `gradle/libs.versions.toml` before assuming a library is available. -- **JetBrains fork aliases:** Version catalog aliases for JetBrains-forked AndroidX artifacts use the `jetbrains-*` prefix (e.g., `jetbrains-lifecycle-runtime-compose`, `jetbrains-navigation3-ui`). Plain `androidx-*` aliases are true Google AndroidX artifacts. Never mix them up in `commonMain`. -- **Compose Multiplatform:** Version catalog aliases for Compose Multiplatform artifacts use the `compose-multiplatform-*` prefix (e.g., `compose-multiplatform-material3`, `compose-multiplatform-foundation`). Never use plain `androidx.compose` dependencies in common Main. -- **Room KMP:** Always use `factory = { MeshtasticDatabaseConstructor.initialize() }` in `Room.databaseBuilder` and `inMemoryDatabaseBuilder`. DAOs and Entities reside in `commonMain`. -- **QR Codes:** Use `rememberQrCodePainter` from `core:ui/commonMain` (powered by `qrcode-kotlin`) for generating QR codes. Do not use Android Bitmap or ZXing APIs in common code. -- **Testing:** Write ViewModel and business logic tests in `commonTest`. Use `Turbine` for Flow testing, `Kotest` for property-based testing, and `Mokkery` for mocking. Use `core:testing` shared fakes. -- **Build-logic conventions:** In `build-logic/convention`, prefer lazy Gradle configuration (`configureEach`, `withPlugin`, provider APIs). Avoid `afterEvaluate` in convention plugins unless there is no viable lazy alternative. - -### C. Namespacing -- **Standard:** Use the `org.meshtastic.*` namespace for all code. -- **Legacy:** Maintain the `com.geeksville.mesh` Application ID. - -## 4. Execution Protocol - -### A.

Development Guidelines & Coding Standards - -### A. UI Development (Jetpack Compose) -- **Material 3:** The app uses Material 3. -- **Strings:** MUST use the **Compose Multiplatform Resource** library in `core:resources` (`stringResource(Res.string.your_key)`). For ViewModels or non-composable Coroutines, use the asynchronous `getStringSuspend(Res.string.your_key)`. NEVER use hardcoded strings, and NEVER use the blocking `getString()` in a coroutine. -- **Dialogs:** Use centralized components in `core:ui` (e.g., `MeshtasticResourceDialog`). -- **Alerts:** Use `AlertHost(alertManager)` from `core:ui/commonMain` in each platform host shell (`Main.kt`, `DesktopMainScreen.kt`). For global responses like traceroute and firmware validation, use the specialized common handlers: `TracerouteAlertHandler(uiViewModel)` and `FirmwareVersionCheck(uiViewModel)`. Do NOT duplicate inline alert-rendering logic or trigger alerts directly during composition. For shared QR/contact dialogs, use the `SharedDialogs(uiViewModel)` composable. -- **Placeholders:** For desktop/JVM features not yet implemented, use `PlaceholderScreen(name)` from `core:ui/commonMain`. Do NOT define inline placeholder composables in feature modules. -- **Theme Picker:** Use `ThemePickerDialog` and `ThemeOption` from `feature:settings/commonMain`. Do NOT duplicate the theme dialog or enum in platform-specific source sets. -- **Adaptive Layouts:** Use `currentWindowAdaptiveInfo(supportLargeAndXLargeWidth = true)` to support the 2026 Desktop Experience breakpoints. Prioritize **higher information density** and mouse-precision interactions for Desktop and External Display (Android 16 QPR3) targets. **Investigate 3-pane "Power User" scenes** (e.g., Node List + Detail + Map/Charts) using Navigation 3 Scenes, `extraPane()`, and draggable dividers (`VerticalDragHandle` + `paneExpansionState`) for widths ≥ 1200dp. -- **Platform/Flavor UI:** Inject platform-specific behavior (e.g., map providers) via `CompositionLocal` from `app`. - -### B. Logic & Data Layer -- **KMP Focus:** All business logic must reside in `commonMain` of the respective `core` module. -- **Platform purity:** Never import `java.*` or `android.*` in `commonMain`. Use KMP alternatives: - - `java.util.Locale` → Kotlin `uppercase()` / `lowercase()` or `expect`/`actual`. - - `java.util.concurrent.ConcurrentHashMap` → `atomicfu` or `Mutex`-guarded `mutableMapOf()`. - - `java.util.concurrent.locks.*` → `kotlinx.coroutines.sync.Mutex`. - - `java.io.*` → Okio (`BufferedSource`/`BufferedSink`). - - `kotlinx.coroutines.Dispatchers.IO` → `org.meshtastic.core.common.util.ioDispatcher` (expect/actual). -- **Shared helpers over duplicated lambdas:** When `androidMain` and `jvmMain` contain identical pure-Kotlin logic (formatting, action dispatch, validation), extract it to a function in `commonMain`. Examples: `formatLogsTo()` in `feature:settings`, `handleNodeAction()` in `feature:node`, `findNodeByNameSuffix()` in `feature:connections`, `MeshtasticAppShell` in `core:ui/commonMain`, and `BaseRadioTransportFactory` in `core:network/commonMain`. -- **KMP file naming:** In KMP modules, `commonMain` and platform source sets (`androidMain`, `jvmMain`) share the same package namespace. If both contain a file with the same name (e.g., `LogExporter.kt`), the Kotlin/JVM compiler will produce a duplicate class error. Use distinct filenames: keep the `expect` declaration in `LogExporter.kt` and put shared helpers in a separate file like `LogFormatter.kt`. -- **`jvmAndroidMain` source set:** Modules that share JVM-specific code between Android and Desktop apply the `meshtastic.kmp.jvm.android` convention plugin. This creates a `jvmAndroidMain` source set via Kotlin's hierarchy template API. Used in `core:common`, `core:model`, `core:data`, `core:network`, and `core:ui`. -- **Hierarchy template first:** Prefer Kotlin's default hierarchy template and convention plugins over manual `dependsOn(...)` graphs. Manual source-set wiring should be reserved for cases the template cannot model. -- **`expect`/`actual` restraint:** Prefer interfaces + DI for platform capabilities; use `expect`/`actual` for small unavoidable platform primitives. Avoid broad expect/actual class hierarchies when an interface-based boundary is sufficient. -- **Feature navigation graphs:** Feature modules export Navigation 3 graph functions as extension functions on `EntryProviderScope` in `commonMain` (e.g., `fun EntryProviderScope.settingsGraph(backStack: NavBackStack)`). Host shells (`app`, `desktop`) assemble these into a single `entryProvider` block. Do NOT define navigation graphs in platform-specific source sets. -- **Concurrency:** Use Kotlin Coroutines and Flow. -- **Dependency Injection:** Use **Koin Annotations** with the K2 compiler plugin (`koin-plugin` in version catalog). The `koin-annotations` library version is unified with `koin-core` (both use `version.ref = "koin"`). The `KoinConventionPlugin` uses the typed `KoinGradleExtension` to configure the K2 plugin (e.g., `compileSafety.set(false)`). Keep root graph assembly in `app`. -- **ViewModels:** Follow the MVI/UDF pattern. Use the multiplatform `androidx.lifecycle.ViewModel` in `commonMain`. Both `app` and `desktop` use `MeshtasticNavDisplay` from `core:ui/commonMain`, which configures `ViewModelStoreNavEntryDecorator` + `SaveableStateHolderNavEntryDecorator`. ViewModels obtained via `koinViewModel()` inside `entry` blocks are scoped to the entry's backstack lifetime and cleared on pop. -- **Navigation host:** Use `MeshtasticNavDisplay` from `core:ui/commonMain` instead of calling `NavDisplay` directly. It provides entry-scoped ViewModel decoration, `DialogSceneStrategy` for dialog entries, and a shared 350 ms crossfade transition. Host modules (`app`, `desktop`) should NOT configure `entryDecorators`, `sceneStrategies`, or `transitionSpec` themselves. -- **BLE:** All Bluetooth communication must route through `core:ble` using Kable. -- **Networking:** Pure **Ktor** — no OkHttp anywhere. Engines: `ktor-client-android` for Android, `ktor-client-java` for desktop/JVM. Use Ktor `Logging` plugin for HTTP debug logging (not OkHttp interceptors). `HttpClient` is provided via Koin in `app/di/NetworkModule` and `core:network/di/CoreNetworkAndroidModule`. -- **Image Loading (Coil):** Use `coil-network-ktor3` with `KtorNetworkFetcherFactory` on **all** platforms. `ImageLoader` is configured in host modules only (`app` via Koin `@Single`, `desktop` via `setSingletonImageLoaderFactory`). Feature modules depend only on `libs.coil` (coil-compose) for `AsyncImage` — never add `coil-network-*` or `coil-svg` to feature modules. -- **Dependencies:** Check `gradle/libs.versions.toml` before assuming a library is available. -- **JetBrains fork aliases:** Version catalog aliases for JetBrains-forked AndroidX artifacts use the `jetbrains-*` prefix (e.g., `jetbrains-lifecycle-runtime-compose`, `jetbrains-navigation3-ui`). Plain `androidx-*` aliases are true Google AndroidX artifacts. Never mix them up in `commonMain`. -- **Compose Multiplatform:** Version catalog aliases for Compose Multiplatform artifacts use the `compose-multiplatform-*` prefix (e.g., `compose-multiplatform-material3`, `compose-multiplatform-foundation`). Never use plain `androidx.compose` dependencies in common Main. -- **Room KMP:** Always use `factory = { MeshtasticDatabaseConstructor.initialize() }` in `Room.databaseBuilder` and `inMemoryDatabaseBuilder`. DAOs and Entities reside in `commonMain`. -- **QR Codes:** Use `rememberQrCodePainter` from `core:ui/commonMain` (powered by `qrcode-kotlin`) for generating QR codes. Do not use Android Bitmap or ZXing APIs in common code. -- **Testing:** Write ViewModel and business logic tests in `commonTest`. Use `Turbine` for Flow testing, `Kotest` for property-based testing, and `Mokkery` for mocking. Use `core:testing` shared fakes. -- **Build-logic conventions:** In `build-logic/convention`, prefer lazy Gradle configuration (`configureEach`, `withPlugin`, provider APIs). Avoid `afterEvaluate` in convention plugins unless there is no viable lazy alternative. - -### C. Namespacing -- **Standard:** Use the `org.meshtastic.*` namespace for all code. -- **Legacy:** Maintain the `com.geeksville.mesh` Application ID. - -## 4. Execution Protocol - -### A.

Pin where possible for reproducibility. - - **Desktop runners:** Reusable CI uses `ubuntu-latest` for the `build-desktop` job in `.github/workflows/reusable-check.yml`; release packaging matrix remains `[macos-latest, windows-latest, ubuntu-24.04, ubuntu-24.04-arm]`. -- **CI JVM tuning:** `gradle.properties` is tuned for local dev (8g heap, 4g Kotlin daemon). CI workflows override via `GRADLE_OPTS` env var to fit the 7GB RAM budget of standard runners: `-Xmx4g` Gradle heap, `-Xmx2g` Kotlin daemon, VFS watching disabled, workers capped at 4. -- **KMP Smoke Compile:** Use `./gradlew kmpSmokeCompile` instead of listing individual module compile tasks. The `kmpSmokeCompile` lifecycle task (registered in `RootConventionPlugin`) auto-discovers all KMP modules and depends on their `compileKotlinJvm` + `compileKotlinIosSimulatorArm64` tasks. -- **`mavenLocal()` gated:** The `mavenLocal()` repository is disabled by default to prevent CI cache poisoning. For local JitPack testing, pass `-PuseMavenLocal` to Gradle. -- **Terminal Pagers:** When running shell commands like `git diff` or `git log`, ALWAYS use `--no-pager` (e.g., `git --no-pager diff`) to prevent the agent from getting stuck in an interactive prompt. -- **Text Search:** Prefer using `rg` (ripgrep) over `grep` or `find` for fast text searching across the codebase. - -### C. Documentation Sync -Update documentation continuously as part of the same change. If you modify architecture, module targets, CI tasks, validation commands, or agent workflow rules, update the relevant docs (`AGENTS.md`, `.github/copilot-instructions.md`, `GEMINI.md`, `docs/agent-playbooks/*`, `docs/kmp-status.md`, and `docs/decisions/architecture-review-2026-03.md`). - -## 5. Troubleshooting -- **Build Failures:** Check `gradle/libs.versions.toml` for dependency conflicts. -- **Missing Secrets:** Check `local.properties`. -- **JDK Version:** JDK 21 is required. -- **Configuration Cache:** Add `--no-configuration-cache` flag if cache-related issues persist. -- **Koin Injection Failures:** Verify the KMP component is included in `app` root module wiring (`AppKoinModule`). \ No newline at end of file +See [AGENTS.md](AGENTS.md) for architecture, conventions, execution protocol, and coding standards. +See [docs/agent-playbooks/README.md](docs/agent-playbooks/README.md) for version baselines and task recipes. diff --git a/build-logic/convention/src/main/kotlin/AndroidApplicationConventionPlugin.kt b/build-logic/convention/src/main/kotlin/AndroidApplicationConventionPlugin.kt index 88ad8350f..3e4ea135f 100644 --- a/build-logic/convention/src/main/kotlin/AndroidApplicationConventionPlugin.kt +++ b/build-logic/convention/src/main/kotlin/AndroidApplicationConventionPlugin.kt @@ -44,7 +44,10 @@ class AndroidApplicationConventionPlugin : Plugin { vectorDrawables.useSupportLibrary = true } - testOptions.animationsDisabled = true + testOptions { + animationsDisabled = true + unitTests.isReturnDefaultValues = true + } buildTypes { getByName("release") { diff --git a/build-logic/convention/src/main/kotlin/AndroidLibraryConventionPlugin.kt b/build-logic/convention/src/main/kotlin/AndroidLibraryConventionPlugin.kt index 3a0dfd7ca..cf3ae81db 100644 --- a/build-logic/convention/src/main/kotlin/AndroidLibraryConventionPlugin.kt +++ b/build-logic/convention/src/main/kotlin/AndroidLibraryConventionPlugin.kt @@ -39,7 +39,10 @@ class AndroidLibraryConventionPlugin : Plugin { extensions.configure { configureKotlinAndroid(this) defaultConfig.testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner" - testOptions.animationsDisabled = true + testOptions { + animationsDisabled = true + unitTests.isReturnDefaultValues = true + } defaultConfig { // When flavorless modules depend on flavored modules (like :core:data), diff --git a/core/ble/src/androidMain/kotlin/org/meshtastic/core/ble/KablePlatformSetup.kt b/core/ble/src/androidMain/kotlin/org/meshtastic/core/ble/KablePlatformSetup.kt index e5033a3c9..e9928f8d5 100644 --- a/core/ble/src/androidMain/kotlin/org/meshtastic/core/ble/KablePlatformSetup.kt +++ b/core/ble/src/androidMain/kotlin/org/meshtastic/core/ble/KablePlatformSetup.kt @@ -45,7 +45,10 @@ internal actual fun PeripheralBuilder.platformConfig(device: BleDevice, autoConn internal actual fun createPeripheral(address: String, builderAction: PeripheralBuilder.() -> Unit): Peripheral = com.juul.kable.Peripheral(address.toIdentifier(), builderAction) +/** ATT protocol header size (opcode + handle) subtracted from MTU to get the usable payload. */ +private const val ATT_HEADER_SIZE = 3 + internal actual fun Peripheral.negotiatedMaxWriteLength(): Int? { val mtu = (this as?

Consider writing additional custom `SceneStrategy` implementations for specialized layouts (e.g., three-pane "Power User" scenes) as the Navigation 3 Scene API matures. ## Decision diff --git a/docs/decisions/testing-consolidation-2026-03.md b/docs/decisions/testing-consolidation-2026-03.md index 1535ef3f8..06612cc4f 100644 --- a/docs/decisions/testing-consolidation-2026-03.md +++ b/docs/decisions/testing-consolidation-2026-03.md @@ -15,142 +15,24 @@ - along with this program.

This consolidates testing dependencies and keeps the module dependency graph clean. +Each KMP module independently declared scattered test dependencies (`junit`, `mockk`, `coroutines-test`, `turbine`), leading to version drift and duplicated test doubles across modules. -## Design Principles +## Decision -### 1. Lightweight Dependencies Only -``` -core:testing -├── depends on: core:model, core:repository -├── depends on: kotlin("test"), kotlinx.coroutines.test, turbine, junit -└── does NOT depend on: core:database, core:data, core:domain -``` +Created `core:testing` as a lightweight shared module for test doubles, fakes, and utilities. It depends only on `core:model` and `core:repository` (no heavy deps like `core:database`). All modules declare `implementation(projects.core.testing)` in `commonTest` to get a unified test dependency set. -**Rationale:** `core:database` has KSP processor dependencies that can slow builds. Isolating `core:testing` with minimal deps ensures: -- Fast compilation of test infrastructure -- No circular dependency risk -- Modules depending on `core:testing` (via `commonTest`) don't drag heavy transitive deps +## Consequences -### 2. No Production Code Leakage -- `:core:testing` is declared **only in `commonTest` sourceSet**, never in `commonMain` -- Test code never appears in APKs or release JARs -- Strict separation between production and test concerns - -### 3.
