AI Integration Plugin Development Guide

Build Commands

• ./gradlew build - Build the entire project
• ./gradlew test - Run all tests
• ./gradlew test --tests "com.didalgo.intellij.chatgpt.chat.metadata.UsageAggregatorTest" - Run a specific test class
• ./gradlew test --tests "*.StandardLanguageTest.testDetection" - Run a specific test method
• ./gradlew runIde - Run the plugin in a development IDE instance
• ./gradlew runPluginVerifier - Verify plugin compatibility with different IDE versions
• ./gradlew koverReport - Generate code coverage report

Code Style Guidelines

• Package Structure: Use com.didalgo.intellij.chatgpt as base package
• Imports: Organize imports alphabetically; no wildcards; static imports last
• Naming: CamelCase for classes; camelCase for methods/variables; UPPER_SNAKE_CASE for constants
• Types: Use annotations (@NotNull, @Nullable) consistently; prefer interface types in declarations
• Error Handling: Use checked exceptions for recoverable errors; runtime exceptions for programming errors
• Documentation: Javadoc for public APIs; comment complex logic; keep code self-explanatory
• Testing: Write unit tests for all business logic; integration tests for UI components
• Architecture: Follow IDEA plugin architecture patterns; use services for global state

Coding Patterns

• Use ChatGptBundle for internationalized strings
• Leverage IntelliJ Platform APIs when possible instead of custom implementations
• Use dependency injection via constructor parameters rather than service lookups
