Implementation Reference
- src/index.ts:514-583 (handler)Registration and inline handler for the get_theme_example tool. Includes schema validation for theme_name and logic to retrieve theme code examples using exact or fuzzy matching from the code examples directory.server.tool( "get_theme_example", "Get code for a React Native theme", { theme_name: z.string().describe("Theme Name"), }, async ({ theme_name }) => { if (!theme_name) { return { content: [ { type: "text", text: "Theme name not specified", }, ], }; } try { // First try exact match const result = getExampleContent("theme", theme_name); if (result.error) { // Try to find by fuzzy match const themesDir = path.join(CODE_EXAMPLES_DIR, "react-native", "theme"); const closestMatch = findClosestMatch(themesDir, theme_name); if (closestMatch) { const fuzzyResult = getExampleContent("theme", closestMatch); return { content: [ { type: "text", text: fuzzyResult.content?.[0] ?? fuzzyResult.error ?? "Error: No content available", }, ], }; } else { return { content: [ { type: "text", text: `Theme ${theme_name} not found`, }, ], }; } } return { content: [ { type: "text", text: result.content?.[0] ?? result.error ?? "Error: No content available", }, ], }; } catch (err) { console.error(`Error getting theme example ${theme_name}:`, err); return { content: [ { type: "text", text: `Error getting theme example: ${err}`, }, ], }; } }, );
- src/index.ts:65-83 (helper)Core helper function used by get_theme_example to load and return the content of a specific example file from the react-native subcategory directory.function getExampleContent(subcategory: string, filename: string): { content?: string[]; path?: string; error?: string } { const searchDir = path.join(CODE_EXAMPLES_DIR, "react-native", subcategory); const filePath = findFileInSubdirectories(searchDir, filename); if (!filePath || !fs.existsSync(filePath)) { return { error: `Example ${filename} not found` }; } try { const content = fs.readFileSync(filePath, 'utf8'); return { content: [content], path: path.relative(BASE_DIR, filePath) }; } catch (err) { console.error(`Error reading example ${filename}:`, err); return { error: `Error reading example ${filename}` }; }
- src/index.ts:87-108 (helper)Helper function for fuzzy matching filenames in a directory that contain the search name, used when exact match fails in get_theme_example.function findClosestMatch(directory: string, searchName: string, extensions: string[] = ['.js', '.jsx', '.ts', '.tsx']) { if (!fs.existsSync(directory)) return null; let closestMatch = null; for (const ext of extensions) { const files = glob.sync(`${directory}/**/*${ext}`); for (const filePath of files) { const fileName = path.basename(filePath); const fileNameNoExt = path.basename(fileName, path.extname(fileName)); if (fileNameNoExt.toLowerCase().includes(searchName.toLowerCase())) { closestMatch = fileNameNoExt; break; } } if (closestMatch) break; } return closestMatch;
