Morfx Demo

Interactive demonstration of Morfx AST transformations with real code modifications.

Features

• Real transformations: Actual file modifications using morfx tools
• Auto backup/restore: Safe demo environment with automatic cleanup
• Multi-language support: Go, PHP, JavaScript, TypeScript
• Visual diffs: Clear before/after comparisons
• Interactive mode: Step through transformations or run all

Usage

# Run interactive demo
go run ./demo/cmd run

# Run specific scenario
go run ./demo/cmd run --scenario go-query

# List available scenarios
go run ./demo/cmd list

Demo Scenarios

• go-query: Query functions with 'User' pattern
• php-replace: Replace updateEmail method
• js-insert: Insert validation function
• ts-delete: Delete deprecated function

How it Works

1. Backup: Creates temporary backup of all sample files
2. Transform: Applies real morfx transformations to actual files
3. Display: Shows before/after diffs with syntax highlighting
4. Restore: Automatically restores original files
5. Repeat: Ready for next demonstration

The demo uses the morfx tools available in this project to perform actual AST transformations on real code files, providing a realistic demonstration of the system's capabilities.
