Implementation Reference

• src/handlers/other-operations.js:587-856 (handler)

  Core implementation of the `handleGitAttributes` function, which handles list, get, and set actions for the .gitattributes file in a Git repository.
  export async function handleGitAttributes({ repo_path, action, pattern = "", attribute = "", }) { try { const attributesPath = path.join(repo_path, ".gitattributes"); switch (action) { case "list": // Check if .gitattributes exists if (!(await fs.pathExists(attributesPath))) { return { content: [ { type: "text", text: JSON.stringify( { success: true, attributes: [], message: ".gitattributes file does not exist", }, null, 2 ), }, ], }; } // Read and parse .gitattributes const content = await fs.readFile(attributesPath, "utf8"); const lines = content .split("\n") .filter((line) => line.trim() && !line.startsWith("#")); const attributes = lines.map((line) => { const parts = line.trim().split(/\s+/); return { pattern: parts[0], attributes: parts.slice(1), }; }); return { content: [ { type: "text", text: JSON.stringify( { success: true, attributes: attributes, }, null, 2 ), }, ], }; case "get": if (!pattern) { return { content: [ { type: "text", text: JSON.stringify( { error: "Pattern is required for get action" }, null, 2 ), }, ], isError: true, }; } // Check if .gitattributes exists if (!(await fs.pathExists(attributesPath))) { return { content: [ { type: "text", text: JSON.stringify( { success: true, pattern: pattern, attributes: [], message: ".gitattributes file does not exist", }, null, 2 ), }, ], }; } // Read and find pattern const getContent = await fs.readFile(attributesPath, "utf8"); const getLines = getContent.split("\n"); const matchingLines = getLines.filter((line) => { const parts = line.trim().split(/\s+/); return parts[0] === pattern; }); if (matchingLines.length === 0) { return { content: [ { type: "text", text: JSON.stringify( { success: true, pattern: pattern, attributes: [], message: `No attributes found for pattern '${pattern}'`, }, null, 2 ), }, ], }; } // Parse attributes const patternAttributes = matchingLines .map((line) => { const parts = line.trim().split(/\s+/); return parts.slice(1); }) .flat(); return { content: [ { type: "text", text: JSON.stringify( { success: true, pattern: pattern, attributes: patternAttributes, }, null, 2 ), }, ], }; case "set": if (!pattern) { return { content: [ { type: "text", text: JSON.stringify( { error: "Pattern is required for set action" }, null, 2 ), }, ], isError: true, }; } if (!attribute) { return { content: [ { type: "text", text: JSON.stringify( { error: "Attribute is required for set action" }, null, 2 ), }, ], isError: true, }; } // Check if .gitattributes exists, create if not if (!(await fs.pathExists(attributesPath))) { await fs.writeFile(attributesPath, ""); } // Read current content const setContent = await fs.readFile(attributesPath, "utf8"); const setLines = setContent.split("\n"); // Check if pattern already exists const patternIndex = setLines.findIndex((line) => { const parts = line.trim().split(/\s+/); return parts[0] === pattern; }); if (patternIndex !== -1) { // Update existing pattern const parts = setLines[patternIndex].trim().split(/\s+/); // Check if attribute already exists if (!parts.includes(attribute)) { parts.push(attribute); setLines[patternIndex] = parts.join(" "); } } else { // Add new pattern setLines.push(`${pattern} ${attribute}`); } // Write back to file await fs.writeFile( attributesPath, setLines.filter(Boolean).join("\n") + "\n" ); return { content: [ { type: "text", text: JSON.stringify( { success: true, message: `Set attribute '${attribute}' for pattern '${pattern}'`, pattern: pattern, attribute: attribute, }, null, 2 ), }, ], }; default: return { content: [ { type: "text", text: JSON.stringify( { error: `Unknown attributes action: ${action}` }, null, 2 ), }, ], isError: true, }; } } catch (error) { return { content: [ { type: "text", text: JSON.stringify( { error: `Failed to manage git attributes: ${error.message}` }, null, 2 ), }, ], isError: true, }; } }
• src/server.js:656-683 (schema)

  Input schema definition for the 'git_attributes' tool, specifying parameters like repo_path, action, pattern, and attribute.
  { name: "git_attributes", description: "Manage git attributes for files.", inputSchema: { type: "object", properties: { repo_path: { type: "string", description: "The path to the local Git repository", }, action: { type: "string", description: "Action (get, set, list)", default: "list", enum: ["get", "set", "list"], }, pattern: { type: "string", description: "File pattern", }, attribute: { type: "string", description: "Attribute to set", }, }, required: ["repo_path", "action"], }, },
• src/server.js:920-920 (registration)

  Registration of the 'git_attributes' handler in the server's handlersMap, mapping the tool name to its implementation function.
