Build instructions

git clone https://github.com/lazystone/digpro.git
cd digpro
./gradlew clean build

# Run application
java -jar build/libs/digpro-0.0.1-SNAPSHOT.jar

Notes

• You can use mouse to move over the map(drag&drop it).
• There is not any tests but there isn't much business logic either.
• Method which is used to filter out visible locations is simple, for bigger datasets something like kd-trees should be used.
• Things like locations URL and auto-reload frequency should be moved to application properties rather than to be hard-coded, but I'm out of time now.
• ViewPort coordinates are stored as fields in MapCanvas, but more correct way is to send them as parameters from mouseDragged to refresh method to avoid possible inconsistency(again out of time to fix this).

Native build

• For better Swing support use https://bell-sw.com/pages/downloads/native-image-kit/#nik-24-(jdk-24)
• Install additional libraries: https://www.graalvm.org/latest/getting-started/linux/#prerequisites-for-native-image-on-linux
• Build normal java application: ./gradlew build
• Generate reachability metadata(for a native build): java -agentlib:native-image-agent=config-output-dir=src/main/resources/META-INF/native-image -jar build/libs/digpro-0.0.1-SNAPSHOT.jar and use application as much as possible.
• Build: ./gradlew nativeCompile
