🐛 Change Type Classification: Bug Fix

This PR addresses a configuration issue with version file management - the .gitignore was configured to ignore src/ragas/_version.py but the file was tracked in git, causing version conflicts.

Code Review

✅ Positive Aspects

1. Correct Problem Identification: The issue was properly identified - src/ragas/_version.py should indeed be auto-generated and ignored in git
2. Clean Solution: Removing the tracked file and relying on the existing gitignore entry is the right approach
3. Consistent with Build System:
   • pyproject.toml:125 specifies version_file = "src/ragas/_version.py"
   • setuptools_scm will auto-generate this file during build
   • The gitignore entry at line 170 correctly excludes this auto-generated file

🔍 Technical Analysis

Version Handling Architecture:

• Project uses setuptools_scm for dynamic versioning (pyproject.toml:35 - dynamic = ["version"])
• Version is imported with fallback in src/ragas/__init__.py:10-12:

  try:
      from ._version import version as __version__
  except ImportError:
      __version__ = "unknown version"

• This graceful fallback ensures the package works even when _version.py doesn't exist

GitIgnore Configuration:

• Line 170: src/ragas/_version.py - correctly ignores the main package version
• Line 171: experimental/ragas_experimental/_version.py - handles experimental package
• Line 87: exclude = ["*.ipynb", "*/_version.py"] - ruff also excludes version files from linting

🎯 Change Assessment

Impact: ✅ Low Risk

• No functional changes to code logic
• Removes build artifact that shouldn't be tracked
• Maintains version handling through setuptools_scm

Testing Considerations: ✅ Well Covered

• The fallback mechanism in __init__.py handles missing version files
• Build system will regenerate the file when needed
• No breaking changes expected

💡 Recommendations

1. Verification: After merge, confirm that:

   • python -c "import ragas; print(ragas.__version__)" works correctly
   • Version displays properly instead of "unknown version"

2. Build Process: The version file will be auto-generated during:

   • Package installation (pip install)
   • Development setup (pip install -e .)
   • Build process (python -m build)

🔒 Security & Best Practices

• ✅ No security concerns
• ✅ Follows Python packaging best practices
• ✅ Aligns with setuptools_scm conventions
• ✅ Maintains clean git history by removing build artifacts

Summary

This is a well-executed fix for a common Python packaging issue. The change correctly removes a build artifact from version control while maintaining proper version handling through the established build system. The implementation is clean, safe, and follows best practices.

Recommendation: ✅ Approve and merge
