Overview

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
