🔧 Technical Implementation

CLI Architecture Enhancement

// New CLI structure with --config support
#[derive(Parser, Debug)]
struct Cli {
    /// Path to a custom configuration file
    #[arg(long)]
    config: Option<String>,
    // ... other fields
}

// Enhanced service initialization
async fn run_offline_command(command: Command, config_path: Option<&str>) -> Result<()> {
    let service = if let Some(config_path) = config_path {
        TuiService::new_with_config_file(config_path).await?
    } else {
        TuiService::new().await?
    };
    // ... rest of implementation
}

Service Integration

impl TuiService {
    /// Initialize a new TUI service with a custom configuration file
    pub async fn new_with_config_file(config_path: &str) -> Result<Self> {
        // Logging initialization
        terraphim_service::logging::init_logging(
            terraphim_service::logging::detect_logging_config(),
        );

        // Device settings and config loading
        let device_settings = DeviceSettings::load_from_env_and_file(None)?;
        let mut config = ConfigBuilder::new_with_id(ConfigId::File(config_path.to_string()))
            .build()?;

        match config.load().await {
            Ok(config) => Ok(Self { config, device_settings }),
            Err(e) => {
                config.create_default().await?;
                Ok(Self { config, device_settings })
            }
        }
    }
}
