Crate codemod_core 

codemod-core

Core engine for codemod-pilot: pattern inference, matching, and transformation.

This crate provides the fundamental building blocks for:

• Inferring code transformation patterns from before/after examples
• Scanning codebases for pattern matches
• Applying transformations with preview and rollback support
• Managing reusable codemod rules

Architecture

• pattern: Pattern inference, matching, and validation
• transform: Transformation application, conflict detection, and rollback
• scanner: Codebase scanning with parallel file processing
• rule: Codemod rule management and serialization
• language: Language adapter trait for tree-sitter integration
• error: Error types and result aliases
