DRY Refactor

Ask the user for the file or directory to refactor. Support multiple files if a directory is provided.

Process

Work through these steps in order, making a separate commit for each extraction:

1. Extract simple helper methods (strings, calculations, parsing)

- Identify duplicated logic - Extract to focused method with clear name - Remove duplicated code immediately after extraction - Commit the extraction

1. Extract complex methods with parameters

- Find similar code blocks with variations - Extract with parameters to handle variations - Remove duplicated code immediately after extraction - Commit the extraction

1. Apply design patterns when beneficial

- Template Method, Strategy, etc. for structural duplication - Only when it improves readability/maintainability - Avoid over-engineering or premature abstraction - Remove duplicated code immediately after extraction - Commit the extraction

After EACH extraction:

• Run tests automatically
• If tests fail, revert the change immediately
• If tests pass and using IDE refactoring tool, commit: . r <description>
• If tests pass but manual refactoring, commit: ^ r <description>
• Remove the now-duplicated code in the same commit

Output

• If no duplication found, report "No duplication found"
• Otherwise provide brief summary at end (e.g., "Extracted 4 methods, removed 3 duplicated blocks")

Commit Format

Use Arlo's Commit Notation (ACN):

• . r extract saveToDatabase method - IDE refactoring or provably safe
• ^ r extract validation logic - Manual refactoring validated by tests
