Re-Markor is a modern, cross-platform port of the original Markor project. It preserves the core philosophy—plain text files, offline-first workflow, and no account lock-in—while leveraging Kotlin Multiplatform (KMP) to bring a unified experience to Android, iOS, and the web.

• 📝 Markdown-First: Fast editing with live preview and syntax highlighting.
• 🌍 Multiplatform: Shared business logic and UI across Android, iOS, JVM, and Web (Wasm).
• 🌐 Web Demo: Run Markor in the browser via Compose Multiplatform for Web.
• 📂 Local-First: Your data stays on your device in plain text files.
• 🏷️ Smart Organization: Pinned notes, archive, labels, trash, and recents.
• 🎨 Modern UX: A complete redesign using Material 3 and Compose Multiplatform.
• 🖼️ Asset Aware: Built-in support for images and attachments within your notes.

This project is a showcase of modern Kotlin Multiplatform development:

• UI: Compose Multiplatform (Material 3)
• Database: Room (KMP)
• Dependency Injection: Koin
• Navigation: Navigation 3
• Preferences: DataStore (KMP)
• Concurrency: Kotlinx Coroutines
• Serialization: Kotlinx Serialization
• Images: Coil3 (KMP)
• Theming: Material Kolor (Dynamic Color)

The project follows a standard KMP layout:

• shared/: The heart of the app. Contains common UI (Compose), business logic, and data layers (Room, DataStore).
• app/: Android-specific entry point and resources.
• iosApp/: iOS-specific Xcode project and Swift entry point.
• webApp/: Wasm browser entry point for the GitHub Pages demo.
• metadata/: App store metadata and screenshots.

• JDK 17 or higher.
• Android Studio (Koala or newer) with the KMP plugin.
• Xcode 15+ (for iOS development).
• CocoaPods (if applicable) or Swift Package Manager.

./gradlew :app:installFlavorDefaultDebug

1. Open iosApp/iosApp.xcodeproj in Xcode.
2. Select a simulator or device.
3. Click Run.

Alternatively, via CLI:

./gradlew :shared:embedAndSignAppleFrameworkForXcode

./gradlew :webApp:wasmJsBrowserDevelopmentRun

Production build:

./gradlew :webApp:wasmJsBrowserDistribution

Simulate the CI build locally before pushing:

./scripts/simulate-web-ci.sh

Deploy manually (after vercel login or with a token):

./scripts/verify-web-deploy.sh --ci
VERCEL_TOKEN=... VERCEL_ORG_ID=... VERCEL_PROJECT_ID=... ./scripts/deploy-web-vercel.sh

Pushes to master run .github/workflows/deploy-web-vercel.yml, which builds the wasm bundle and deploys to Vercel. Add these repository secrets:
