[sean2077]

Overview

This PR modernizes the jsonpath-python project with significant improvements to infrastructure, features, and bug fixes.

Major Changes

🏗️ Infrastructure Modernization

• Migrate from setup.py to pyproject.toml with uv package manager
• Add GitHub Actions CI/CD workflows (testing, linting, automated releases)
• Configure semantic-release for automated versioning and changelog generation
• Add pre-commit hooks with ruff for code quality
• Reorganize test structure (test/ → tests/)

✨ New Features

• Update Function ([FEAT] Update Function #12): Add JSONPath.update() method to modify JSON data using JSONPath expressions
  • Support both static values and callback functions
  • Handle complex paths including filters, slices, and recursive descent
• Enhanced Filter Support (Contains and =~ operators for filtering #13): Add in operator and regex matching (=~) in filter expressions

🐛 Bug Fixes

• is it possible to filter NULLs? #9: Fix field extractor to filter out missing keys
• Not possible to compare str and int when sorting #10: Raise JSONPathTypeError on mixed type sorting attempts
• incorrect output when using filters at leaf #15: Fix filters with bracket notation returning empty results
• Can't do filter using fields between single quotes #16: Support quoted keys in filters and paths
• False positive errors #17: Resolve false positive errors and parsing bugs
• 建议优化PATH的格式 #7: Modernize project structure and fix path output

📚 Documentation

• Add "Why jsonpath-python?" section to README
• Document update function usage
• Clarify feature comparisons with other libraries
• Update examples and improve clarity

Breaking Changes

None - This is backward compatible.

Testing

• All existing tests pass
• Added comprehensive test coverage for new update function
• Added test cases for bug fixes
