/** * List Themes Command * * DESIGN PATTERNS: * - Command pattern with Commander for CLI argument parsing * - Async/await pattern for asynchronous operations * - Error handling pattern with try-catch and proper exit codes * * CODING STANDARDS: * - Use async action handlers for asynchronous operations * - Provide clear option descriptions and default values * - Handle errors gracefully with process.exit() * - Log progress and errors to console * - Use Commander's .option() and .argument() for inputs * * AVOID: * - Synchronous blocking operations in action handlers * - Missing error handling (always use try-catch) * - Hardcoded values (use options or environment variables) * - Not exiting with appropriate exit codes on errors */ import { print } from '@agiflowai/aicode-utils'; import { Command } from 'commander'; import { ListThemesTool } from '../tools/ListThemesTool'; interface ListThemesOptions { appPath?: string; } /** * List all available theme configurations from CSS files */ export const listThemesCommand = new Command('list-themes') .description( 'List all available theme configurations from CSS files configured in project.json style-system config', ) .option( '-a, --app-path <path>', 'App path to read theme config from project.json (e.g., "apps/my-app")', ) .action(async (options: ListThemesOptions): Promise<void> => { try { const tool = new ListThemesTool(); const result = await tool.execute({ appPath: options.appPath }); if (result.isError) { const firstContent = result.content[0]; const errorText = firstContent?.type === 'text' ? firstContent.text : 'Unknown error'; throw new Error(errorText); } const firstContent = result.content[0]; print.info(firstContent?.type === 'text' ? firstContent.text : ''); } catch (error) { print.error('Error listing themes:', error instanceof Error ? error.message : String(error)); process.exit(1); } });
