New features

• Advanced pagination features

  • Added the subline_by parameter for creating paragraph headers before each page group.
  • Enhanced group_by functionality with hierarchical value suppression within groups.
  • Implemented page context restoration for multi-page tables with group_by.

• Enhanced color system

  • Complete 657-color support with full r2rtf R package compatibility.

• Text conversion improvements

  • Text conversion (LaTeX to Unicode) enabled by default for all components.
  • Better handling of special characters and symbols.
  • Enhanced validation for text conversion operations.

• Table formatting

  • Added the as_table parameter for RTFFootnote and RTFSource components.
  • Auto-inheritance of col_rel_width from rtf_body to rtf_column_header.
  • Improved handling of table borders and footnote placement.

Architecture improvements

• Service-oriented architecture

  • Introduced dedicated service layer for complex operations.
  • Implemented strategy pattern for encoding (SinglePageStrategy, PaginatedStrategy).
  • Created RTFEncodingEngine for strategy orchestration.

• Code organization

  • Consolidated constants and eliminated magic numbers throughout the codebase.
  • Method decomposition and improved input validation.
  • Cleaner public interfaces with thorough error handling.

Dependency changes

• Removed numpy and pandas as hard dependencies.
• Moved pyarrow to development dependencies.
• Now uses narwhals for DataFrame abstraction.
• Prefer polars as the primary DataFrame interface.

Documentation

• Added vignette-style articles to document the new features.
• Reorganized API reference for better user experience.
• Renamed documentation files to use hyphens consistently.
• Updated all examples to use modern best practices.
• Fixed Polars DataOrientationWarning in documentation examples.

Testing

• Added single-page RTF tests with fixtures generated by r2rtf.
• Added extensive multi-page tests for the as_table feature.

rtflite 0.1.0

New features

• Introduced core RTF document components, such as RTFDocument, RTFPage, RTFTitle, RTFColumnHeader, and RTFBody. These classes establish the foundation for composing structured RTF documents with a text encoding pipeline. Use Pydantic for data validation.

• Implemented a LibreOffice-based document converter for RTF to PDF conversion with automatic LibreOffice detection mechanisms under Linux, macOS, and Windows.

Documentation

• Added an article on creating baseline characteristics tables.
• Integrated code coverage reports via pytest-cov into the documentation site.
