文件编辑：AI辅助代码修改

​

​

File editing in Claude Code isn't just about changing text—it's a carefully orchestrated pipeline designed to handle the complexities of AI-assisted code modification:

在 Claude Code 中，文件编辑不仅仅是更改文本——它是一个精心编排的管道，旨在处理 AI 辅助代码修改的复杂性：

class FileEditingPipeline { static async executeEdit( tool: EditTool, input: EditInput, context: ToolContext ): Promise<EditResult> { const validation = await this.validateEdit(input, context); if (!validation.valid) { return { success: false, error: validation.error }; } const prepared = await this.prepareEdit(input, validation.fileState); const result = await this.applyEdit(prepared); const verified = await this.verifyEdit(result, input); return verified; } private static fileStates = new Map<string, FileState>(); interface FileState { content: string; hash: string; mtime: number; encoding: BufferEncoding; lineEndings: '\\n' | '\\r\\n' | '\\r'; isBinary: boolean; size: number; } }

class FileEditingPipeline { static async executeEdit( tool: EditTool, input: EditInput, context: ToolContext ): Promise<EditResult> { const validation = await this.validateEdit(input, context); if (!validation.valid) { return { success: false, error: validation.error }; } const prepared = await this.prepareEdit(input, validation.fileState); const result = await this.applyEdit(prepared); const verified = await this.verifyEdit(result, input); return verified; } private static fileStates = new Map<string, FileState>(); interface FileState { content: string; hash: string; mtime: number; encoding: BufferEncoding; lineEndings: '\\n' | '\\r\\n' | '\\r'; isBinary: boolean; size: number; } }

Why Multiple Tools Instead of One Universal Editor?

为什么使用多个工具而不是一个通用编辑器？

Each tool provides specific guarantees that a universal editor couldn't maintain while remaining LLM-friendly.

每个工具提供特定的保证，而通用编辑器在保持 LLM 友好的同时无法维持这些保证。

The most critical challenge in file editing is the line number prefix problem:

文件编辑中最关键的挑战是行号前缀问题：

const readOutput = ` 1 function hello() { 2 console.log('Hello, world!'); 3 } `; const wrongOldString = "2...
