- Updated README with new configuration details.
Fixed OpenAI Chat Completions for codex
- Added handling for OpenAI-compatible providers during client reload.
- Implemented client unregistration for old clients during reload.
- Improved logging for detailed client reload insights.
Expand `AuthDir` handling to support tilde (`~`) for home directory resolution
- Added logic to replace `~` with the user's home directory in `AuthDir`.
- Prevents errors when using `~` in configuration paths.
- Introduced retry counter with a configurable ` RequestRetry ` limit in all handlers.
- Enhanced error handling with specific HTTP status codes for switching clients.
- Standardized response forwarding for non-retriable errors.
- Improved logging for quota and client switch scenarios.
- Modularized handlers into dedicated packages (`gemini`, `claude`, `cli`) for better structure.
- Centralized `ErrorResponse` and `ErrorDetail` types under `handlers` package for reuse.
- Updated all handlers to utilize the shared `ErrorResponse` model.
- Introduced specialization of handler structs (`GeminiAPIHandlers`, `ClaudeCodeAPIHandlers`, `GeminiCLIAPIHandlers`) for improved clarity and separation of concerns.
- Refactored `getClient` logic with additional properties and better state management.
Refactor `translator` package by modularizing code for `claude` and `gemini`
- Moved Claude-specific logic (`PrepareClaudeRequest`, `ConvertCliToClaude`) to `translator/claude/code`.
- Moved Gemini-specific logic (`FixCLIToolResponse`) to `translator/gemini/cli` for better package structure.
- Updated affected handler imports and method references.
Add comprehensive package-level documentation across key modules
- Introduced detailed package-level documentation for core modules: `auth`, `client`, `cmd`, `handlers`, `util`, `watcher`, `config`, `translator`, and `api`.
- Enhanced code readability and maintainability by clarifying the purpose and functionality of each package.
- Aligned documentation style and tone with existing codebase conventions.
Refactor API handlers and translator modules for improved clarity and consistency
- Standardized handler struct names (`GeminiAPIHandlers`, `ClaudeCodeAPIHandlers`, `GeminiCLIAPIHandlers`, `OpenAIAPIHandlers`) and updated related comments.
- Fixed unnecessary `else` blocks in streaming logic for cleaner error handling.
- Renamed variables for better readability (`responseIdResult` to `responseIDResult`, `activationUrl` to `activationURL`, etc.).
- Addressed minor inconsistencies in API handler comments and SSE header initialization.
- Improved modularization of `claude` and `gemini` translator components.
Standardize configuration field naming for consistency across modules
- Renamed `ProxyUrl` to `ProxyURL`, `ApiKeys` to `APIKeys`, and `ConfigQuotaExceeded` to `QuotaExceeded`.
- Updated all relevant references and comments in `config`, `auth`, `api`, `util`, and `watcher`.
- Ensured consistent casing for `GlAPIKey` debug logs.
- Introduced `Watcher` for monitoring updates to the configuration file and authentication directory.
- Integrated file watching into `StartService` to handle dynamic changes without restarting.
- Enhanced API server and handlers to support client and configuration updates.
- Updated `.gitignore` to include `docs/` directory.
- Modified go dependencies to include `fsnotify` for the file watcher.
