# Title: Implement PDF Generation for Project Progress and Dependency Overview
|
||
# Status: pending
|
||
# Dependencies: None
|
||
# Priority: medium
|
||
# Description: Develop a feature to generate a PDF report summarizing the current project progress and visualizing the dependency chain of tasks.
|
||
# Details:
|
||
This task involves creating a new CLI command named 'progress-pdf' within the existing project framework to generate a PDF document. The PDF should include: 1) A summary of project progress, detailing completed, in-progress, and pending tasks with their respective statuses and completion percentages if applicable. 2) A visual representation of the task dependency chain, leveraging the output format from the 'diagram' command (Task 70) to include Mermaid diagrams or similar visualizations converted to image format for PDF embedding. Use a suitable PDF generation library (e.g., jsPDF for JavaScript environments or ReportLab for Python) compatible with the project’s tech stack. Ensure the command accepts optional parameters to filter tasks by status or ID for customized reports. Handle large dependency chains by implementing pagination or zoomable image sections in the PDF. Provide error handling for cases where diagram generation or PDF creation fails, logging detailed error messages for debugging. Consider accessibility by ensuring text in the PDF is selectable and images have alt text descriptions. Integrate this feature with the existing CLI structure, ensuring it aligns with the project’s configuration settings (e.g., output directory for generated files). Document the command usage and parameters in the project’s help or README file.

# Test Strategy:
|
||
Verify the completion of this task through a multi-step testing approach: 1) Unit Tests: Create tests for the PDF generation logic to ensure data (task statuses and dependencies) is correctly fetched and formatted. Mock the PDF library to test edge cases like empty task lists or broken dependency links. 2) Integration Tests: Run the 'progress-pdf' command via CLI to confirm it generates a PDF file without errors under normal conditions, with filtered task IDs, and with various status filters. Validate that the output file exists in the specified directory and can be opened. 3) Content Validation: Manually or via automated script, check the generated PDF content to ensure it accurately reflects the current project state (compare task counts and statuses against a known project state) and includes dependency diagrams as images. 4) Error Handling Tests: Simulate failures in diagram generation or PDF creation (e.g., invalid output path, library errors) and verify that appropriate error messages are logged and the command exits gracefully. 5) Accessibility Checks: Use a PDF accessibility tool or manual inspection to confirm that text is selectable and images have alt text. Run these tests across different project sizes (small with few tasks, large with complex dependencies) to ensure scalability. Document test results and include a sample PDF output in the project repository for reference.

# Subtasks:
|
||
## 1. Research and select PDF generation library [pending]
|
||
### Dependencies: None
|
||
### Description: Evaluate available PDF generation libraries for Node.js that can handle diagrams and formatted text
|
||
### Details:
|
||
Compare libraries like PDFKit, jsPDF, and Puppeteer based on features, performance, and ease of integration. Consider compatibility with diagram visualization tools. Document findings and make a recommendation with justification.
|
||
|
||
## 2. Design PDF template and layout [pending]
|
||
### Dependencies: 72.1
|
||
### Description: Create a template design for the project progress PDF including sections for summary, metrics, and dependency visualization
|
||
### Details:
|
||
Design should include header/footer, progress summary section, key metrics visualization, dependency diagram placement, and styling guidelines. Create a mockup of the final PDF output for approval.
|
||
|
||
## 3. Implement project progress data collection module [pending]
|
||
### Dependencies: 72.1
|
||
### Description: Develop functionality to gather and process project data for the PDF report
|
||
### Details:
|
||
Create functions to extract task completion percentages, milestone status, timeline adherence, and other relevant metrics from the project database. Include data transformation logic to prepare for PDF rendering.
|
||
|
||
## 4. Integrate with dependency visualization system [pending]
|
||
### Dependencies: 72.1, 72.3
|
||
### Description: Connect to the existing diagram command to generate visual representation of task dependencies
|
||
### Details:
|
||
Implement adapter for the diagram command output to be compatible with the PDF generation library. Handle different scales of dependency chains and ensure proper rendering of complex relationships.
|
||
|
||
## 5. Build PDF generation core functionality [pending]
|
||
### Dependencies: 72.2, 72.3, 72.4
|
||
### Description: Develop the main module that combines data and visualizations into a formatted PDF document
|
||
### Details:
|
||
Implement the core PDF generation logic using the selected library. Include functions for adding text sections, embedding visualizations, formatting tables, and applying the template design. Add pagination and document metadata.
|
||
|
||
## 6. Create export options and command interface [pending]
|
||
### Dependencies: 72.5
|
||
### Description: Implement user-facing commands and options for generating and saving PDF reports
|
||
### Details:
|
||
Develop CLI commands for PDF generation with parameters for customization (time period, detail level, etc.). Include options for automatic saving to specified locations, email distribution, and integration with existing project workflows.
