Kvaesitso is a production-grade, search-focused Android launcher and home-screen replacement. The app aggregates local and cloud content - apps, contacts, calendar events, files, locations, websites, Wikipedia articles, calculator results, and unit conversions - through a unified `SearchService`, then presents results in a Jetpack Compose UI with configurable widgets, themes, gestures, and plugin-backed data sources. It ships a ContentProvider-based plugin SDK that lets third-party packages extend search, weather, calendar, contact, file, and location providers. Cloud integration includes Nextcloud/ownCloud file search, multiple weather providers (Met.no, BrightSky, OpenWeatherMap), OpenStreetMap/Overpass location lookup, and a Material You-style color engine for theming. Architecturally this is a large modular monorepo with 40+ Gradle modules layered into `app`, `core`, `data`, `services`, `libs`, and `plugins`. Dependencies are wired with Koin; persistence uses Room with 30+ schema versions and hand-written migrations plus DataStore; concurrency is Kotlin coroutines and Flow; the UI is Compose/Material3. Primary entry points are `LauncherActivity`, `AssistantActivity`, the settings activities, and the plugin SDK. The codebase demonstrates strong separation of concerns, repository-per-domain organization, and a substantial library of custom Compose components for settings, bottom sheets, drag-and-drop, widgets, and animations. Despite active maintenance and nightly CI, drift signals exist: reflection into hidden `StatusBarManager` for global actions, many deprecated compatibility fields and migrations, hardcoded web/feed blocklists, and several external API integrations that can change without notice. The strongest, most reusable pieces are isolated algorithms and parsers: fzf-style fuzzy matching, OSM opening-hours parsing, searchable string normalization, and map tile rendering. These are genuinely extractable and would transfer cleanly to other search or geodata projects.
The LLM identified 4 files worth highlighting for reuse:
Pure-Kotlin port of fzf's scoring algorithm for subsequence matches. It ranks contiguous matches above scattered ones, boosts prefix matches, and includes a dedicated unit test suite. No Android framework dependencies, making it directly reusable in any search or autocomplete system.
Parses OpenStreetMap `opening_hours` syntax into a structured schedule model, handling day ranges, time windows, holidays, week-number exceptions, and mixed rules. It has focused tests and stays isolated from Android framework code, making it valuable to geodata applications that display venue hours.
Wraps ICU transliteration to produce a normalized, accent-insensitive string index for search, with per-thread caching to avoid repeated initialization costs. This solves a common multilingual search problem and can be extracted as a standalone normalization utility.
Implements a slippy-map tile composable with tile-coordinate and tile-range math, pan/zoom handling, cache-friendly image loading, and theming. It isolates map rendering from the launcher search UI and can be reused in any Android Compose app needing a lightweight OpenStreetMap-style tile viewer.
