Description

This PR addresses issue #53 by integrating the existing PDF export functionality into the main Harmony API. The PDF export functionality was already fully implemented and comprehensively tested, but not exposed through the main API. This change completes the integration, allowing users to create human-readable PDF reports with statistics, graphics, and professional formatting.

Changes:

• Added imports for generate_pdf_report, generate_harmony_pdf_report, and generate_basic_harmony_report from services.export_pdf_report
• Included graceful fallback with helpful error messages if PDF dependencies are not installed
• Makes the comprehensive PDF export feature accessible to end users through the main harmony module
• No new third-party dependencies added to requirements (existing functionality uses fpdf2, matplotlib, seaborn)

Fixes #53

Type of change

• New feature (non-breaking change which adds functionality)
• Bug fix (non-breaking change which fixes an issue)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Requires a documentation revision

Testing

The PDF export functionality is already comprehensively tested with extensive unit tests in tests/test_export_pdf_report.py. These tests cover:

• Original function backward compatibility
• Enhanced PDF generation with and without graphics
• Error handling and edge cases
• Statistics calculation
• Graceful fallback when dependencies unavailable
• Large dataset performance
• Multiple output formats

All existing tests continue to pass. The change only adds imports to expose existing functionality.

Test Configuration

• Library version: 1.0.7
• OS: Cross-platform (tested on multiple systems via existing CI)
• Toolchain: Python 3.8+

Checklist

• My PR is for one issue, rather than for multiple unrelated fixes.
• My code follows the style guidelines of this project. I have applied a Linter (recommended: Pycharm's code formatter) to make my whitespace consistent with the rest of the project.
• I have performed a self-review of my own code
• I have commented my code, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation
• My changes generate no new warnings
• I have added tests that prove my fix is effective or that my feature works (existing comprehensive tests)
• New and existing unit tests pass locally with my changes
• Any dependent changes have been merged and published in downstream modules
• I have checked my code and corrected any misspellings
• The Harmony API is not broken by my change to the Harmony Python library (no breaking changes)
• I add third party dependencies only when necessary. No new dependencies added in this PR.
• If I introduced a new feature, I documented it - the feature is already documented in the existing implementation

Additional Context

This change enables users to call PDF export functions directly after importing harmony:

import harmony

# Match instruments
instruments = [harmony.example_instruments["CES_D English"], harmony.example_instruments["GAD-7 Portuguese"]]
match_response = harmony.match_instruments(instruments)

# Generate PDF report (now available in main API)
harmony.generate_harmony_pdf_report(match_response, instruments, "report.pdf", include_graphics=True)

The implementation includes graceful error handling, so users who don't have PDF dependencies installed will receive clear installation instructions.…init_.py

This commit addresses issue #53 by integrating the existing PDF export functionality into the main Harmony API.

Changes:

• Added imports for generate_pdf_report, generate_harmony_pdf_report, and generate_basic_harmony_report from services.export_pdf_report
• Included graceful fallback with helpful error messages if PDF dependencies are not installed
• Makes the comprehensive PDF export feature accessible to end users through the main harmony module

The PDF export functionality was already fully implemented and tested, but not exposed through the main API. This change completes the integration, allowing users to create human-readable PDF reports with statistics, graphics, and professional formatting as requested in issue #53.

Description

Please include a summary of the change and which issue is fixed. Please also include relevant context. List any dependencies that are required for this change. Ideally we avoid introducing any new third party dependencies in requirements.txt and pyproject.toml unless absolutely necessary, because this makes the project more susceptible to breaking whenever a third party library is updated.

Fixes # (issue)

Type of change

Please delete options that are not relevant.

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Requires a documentation revision

Testing

Please describe the tests that you ran to verify your changes. Provide instructions so we can reproduce. Please also list any relevant details for your test configuration

• Test A
• Test B

Since the Harmony Python package is used by the Harmony API (which is itself used by the R library and the web app), we need to avoid making any changes that break the Harmony API. Please also run the Harmony API unit tests and check that the API still runs with your changes to the Python package: https://github.com/harmonydata/harmonyapi

Test Configuration

• Library version:
• OS:
• Toolchain:

Thanks so much @DHANUSHRAJA22 ! I tried the PDF report and it's pretty cool
