Worked on the tauri-apps/tauri repository to enhance the Tauri CLI by adding support for TOML and JSON5 configuration files through the --config option. This involved updating the parsing logic and dependencies to accommodate the new formats, allowing users to define project configurations with greater flexibility. The implementation leveraged Rust for CLI development and configuration management, ensuring robust handling of both TOML and JSON5 files. Documentation was refreshed to include detailed usage examples and format specifications, streamlining the setup process for users and laying the groundwork for future expansion to additional configuration formats within the Tauri ecosystem.
