Feature Request: Copy/Paste Lines by Range in Claude Code

Feature Request: Copy/Paste Lines by Range in Claude Code

Summary

Add ability to copy specific line ranges from files (e.g., lines 56-94) and paste them to target locations - a simple but powerful copy/paste function that could save significant development time. And also save millions of dollars on electricity consumption.

Proposed Implementation

Command Line Interface

# Copy lines 56-94 from source.py and insert at line 120 in target.py
claude copy source.py 56:94 target.py:120

# Copy to end of file
claude copy source.py 56:94 target.py:end

# Copy to clipboard for manual placement
claude copy source.py 56:94 --clipboard

Interactive Mode

claude> copy source.py 56:94
[Lines copied to buffer]
claude> paste target.py 120
[Lines inserted at specified location]

Use Cases

• Code Refactoring: Move functions/classes between files
• Template Creation: Copy common patterns to new files
• Documentation: Extract code examples for docs
• Testing: Copy production code for test scenarios
• Legacy Migration: Move code between old/new architectures

Business Impact

This basic functionality could streamline countless development workflows, reduce context switching between editors, and save substantial time across development teams.

Current Workaround

Manual copy/paste from external editors, but native Claude Code integration would be far more efficient and maintain the terminal-first workflow.

Technical Considerations

• Should respect file permissions and safety checks
• Could integrate with existing view and edit commands
• Maintains compatibility with current file editing workflows
