Same pattern as core/ble: absent from the configuration graph by default (repo's org.gradle.isolated-projects=true forbids a second project registering wasmJs without this gate, per the earlier finding on the web-target branch). Unlike core/ble, core:common has no native-only dependency, so no source-set hierarchy split is needed here -- just the target plus a wasmJsMain actual for each existing expect (next commit).
:core:common
Overview
Targets: Android · JVM (Desktop) · iOS
The :core:common module contains low-level utility functions, extensions, and common data structures that do not depend on any other Meshtastic-specific modules. It is designed to be highly reusable across the project.
Key Components
1. util package
Contains general-purpose extensions and helpers:
- Coroutines: Helpers for structured concurrency and Flow transformations.
- Time: Utilities for handling timestamps and durations, plus
DateFormatterfor display dates. - Exceptions: Standardized exception types for common error scenarios.
NumberFormatter: Locale-aware number formatting (pre-format floats before Compose display).UrlUtils/CommonUri: URL helpers and a multiplatform URI abstraction.
2. MetricFormatter.kt
Centralized utility for display strings — temperature, voltage, current, percent, humidity, pressure, SNR, RSSI. Ensures consistent unit spacing and formatting across all UI surfaces.
3. BuildConfigProvider.kt
An interface for accessing build-time configuration in a multiplatform-friendly way.
