# Task ID: 41
|
|
# Title: Implement Visual Task Dependency Graph in Terminal
|
|
# Status: pending
|
|
# Dependencies: None
|
|
# Priority: medium
|
|
# Description: Create a feature that renders task dependencies as a visual graph using ASCII/Unicode characters in the terminal, with color-coded nodes representing tasks and connecting lines showing dependency relationships.
|
|
# Details:
|
|
This implementation should include:
|
|
|
|
1. Create a new command `graph` or `visualize` that displays the dependency graph.
|
|
|
|
2. Design an ASCII/Unicode-based graph rendering system that:
|
|
- Represents each task as a node with its ID and abbreviated title
|
|
- Shows dependencies as directional lines between nodes (→, ↑, ↓, etc.)
|
|
- Uses color coding for different task statuses (e.g., green for completed, yellow for in-progress, red for blocked)
|
|
- Handles complex dependency chains with proper spacing and alignment
|
|
|
|
3. Implement layout algorithms to:
|
|
- Minimize crossing lines for better readability
|
|
- Properly space nodes to avoid overlapping
|
|
- Support both vertical and horizontal graph orientations (as a configurable option)
|
|
|
|
4. Add detection and highlighting of circular dependencies with a distinct color/pattern
|
|
|
|
5. Include a legend explaining the color coding and symbols used
|
|
|
|
6. Ensure the graph is responsive to terminal width, with options to:
|
|
- Automatically scale to fit the current terminal size
|
|
- Allow zooming in/out of specific sections for large graphs
|
|
- Support pagination or scrolling for very large dependency networks
|
|
|
|
7. Add options to filter the graph by:
|
|
- Specific task IDs or ranges
|
|
- Task status
|
|
- Dependency depth (e.g., show only direct dependencies or N levels deep)
|
|
|
|
8. Ensure accessibility by using distinct patterns in addition to colors for users with color vision deficiencies
|
|
|
|
9. Optimize performance for projects with many tasks and complex dependency relationships
|
|
|
|
# Test Strategy:
|
|
1. Unit Tests:
|
|
- Test the graph generation algorithm with various dependency structures
|
|
- Verify correct node placement and connection rendering
|
|
- Test circular dependency detection
|
|
- Verify color coding matches task statuses
|
|
|
|
2. Integration Tests:
|
|
- Test the command with projects of varying sizes (small, medium, large)
|
|
- Verify correct handling of different terminal sizes
|
|
- Test all filtering options
|
|
|
|
3. Visual Verification:
|
|
- Create test cases with predefined dependency structures and verify the visual output matches expected patterns
|
|
- Test with terminals of different sizes, including very narrow terminals
|
|
- Verify readability of complex graphs
|
|
|
|
4. Edge Cases:
|
|
- Test with no dependencies (single nodes only)
|
|
- Test with circular dependencies
|
|
- Test with very deep dependency chains
|
|
- Test with wide dependency networks (many parallel tasks)
|
|
- Test with the maximum supported number of tasks
|
|
|
|
5. Usability Testing:
|
|
- Have team members use the feature and provide feedback on readability and usefulness
|
|
- Test in different terminal emulators to ensure compatibility
|
|
- Verify the feature works in terminals with limited color support
|
|
|
|
6. Performance Testing:
|
|
- Measure rendering time for large projects
|
|
- Ensure reasonable performance with 100+ interconnected tasks
