Codemod
Codemod 是一套用于执行结构化源代码转换的软件工具。它作为一个自动化代码库迁移工具，利用抽象语法树操作而非简单的正则表达式，在多个文件之间执行大规模重构。
该项目通过一个提供彩色差异的交互式转换界面脱颖而出，允许用户手动审查、接受或修改每个匹配项。它还支持分布式重构工作流，能够将代码库分割成指定的任务块，以便在多个贡献者之间分配迁移任务。
该工具集涵盖了脚本化转换逻辑、模式匹配搜索引擎以及基于扩展的文件过滤功能，以将操作限制在项目的特定子集中。
Features
- Automated Large-Scale Refactoring - Executes synchronized structural changes across an entire codebase using automated search and substitution.
- AST-Based Source Transformations - Provides the ability to modify source code by replacing abstract syntax tree nodes while preserving formatting.
- Automated Codebase Migration Tools - Provides a system for executing complex structural refactors with support for human oversight and task segmentation.
- Interactive Change Reviewers - Provides an interactive interface for verifying and selectively accepting code modifications before writing them to the filesystem.
- Automated Migration Codemods - Automates syntax updates and breaking change resolution across a project using scripted transformations.
- Source Code Transformation Engines - Provides an engine for defining custom scripts to automate search and replace operations based on code patterns.
- Structural Pattern Matching - Identifies specific code fragments using structural pattern matching based on AST bindings and regular expressions.
- AST-Based Refactorers - Programmatically modifies internal syntax trees to apply fixes and refactors across large codebases.
- Code Transformation Tools - Provides utilities for structural code modifications based on language grammars and AST manipulation.
- Custom Refactoring Logic - Allows defining specialized source code transformations through custom imperative JavaScript logic.
- Logical Pattern Substitution - Implements complex code changes that require logical scripts instead of basic regular expression replacements.
- Scripted Transformations - Supports custom scripting for performing sophisticated refactoring logic beyond simple regular expression substitutions.
- Interactive Code Editing - Offers an interactive editing experience with diff-style updates for guiding multi-step structural changes.
- Refactoring Task Segmentation - Enables dividing a codebase into manageable chunks based on directory paths to distribute migration tasks.
- Distributed Refactoring Workflows - Provides a workflow for dividing massive codebase cleanups among developers by segmenting files into assigned work blocks.
