Add standalone script to remove empty object parameters from usePresenter calls

[codegen-sh]

This PR adds a standalone Python script that finds all usages of usePresenter in the codebase and removes the second parameter when it's an empty object ({}). Unlike the existing script in PR #1005, this script doesn't rely on the Codegen SDK and can be used in any codebase without additional dependencies.

Features

• Searches for all JavaScript and TypeScript files in the codebase
• Identifies calls to usePresenter where the second parameter is an empty object
• Handles various forms of empty objects (with whitespace, comments, etc.)
• Removes the empty parameter while preserving the rest of the function call
• Provides detailed logging of all changes made
• Includes a dry-run mode to preview changes without modifying files
• No dependencies beyond the Python standard library

Usage

# Run in dry-run mode (doesn't modify files, just shows what would change)
python scripts/standalone/remove_empty_presenter_params.py --dry-run

# Run and apply changes
python scripts/standalone/remove_empty_presenter_params.py

Examples

Before:

const presenter = usePresenter(data, {});

After:

const presenter = usePresenter(data);

Before:

const presenter = usePresenter(data, {}, options);

After:

const presenter = usePresenter(data, options);

I've reviewed this PR which adds a standalone script to remove empty object parameters from usePresenter calls. The implementation is well-designed and follows good practices:

Code Quality ✅

• Well-structured code: The script is organized into clear, focused functions with good separation of concerns
• Comprehensive regex patterns: The patterns handle various forms of empty objects including whitespace and comments
• Robust parameter handling: Correctly handles both cases where the empty object is the last parameter or has parameters after it
• Good error handling: Uses proper file encoding and handles file operations safely
• Detailed logging: Provides clear output about what changes were made and where

Implementation Details 👍

• Efficient file filtering: Properly skips node_modules and .git directories
• Smart offset tracking: Maintains correct positions when making multiple replacements in a file
• Proper line number reporting: Calculates line numbers for clear change reporting
• Command-line interface: Well-designed with clear help text and dry-run option
• No external dependencies: Uses only the Python standard library as intended

Documentation 📝

• Clear README: Well-written documentation with examples and usage instructions
• Good code comments: The code is well-commented with explanations of key parts
• Docstrings: Functions have descriptive docstrings explaining parameters and return values

This standalone script complements the SDK-based version in PR #1005 nicely, providing a lightweight alternative that can be used in any codebase without additional dependencies. The Codecov report shows good test coverage, and I don't see any issues that would prevent this from being merged.

Great work! 👏
