Implement Human-Readable Table Formatter for String Analysis Results

[unclesp1d3r]

Overview

This issue tracks the implementation of a human-readable table formatter that displays string analysis results in a sorted, well-aligned tabular format. This formatter will provide users with an intuitive way to review extracted strings from binary analysis.

Context

The string analyzer needs a user-friendly output format for interactive use and manual review. While JSON and other machine-readable formats serve automation needs, developers and security researchers require a clean, sorted table view to quickly identify patterns, assess results, and make informed decisions during binary analysis workflows.

Requirements

• Requirement ID: 6.2
• Blocked by: Output Formatting Framework (must be implemented first)
• Task ID: stringy-analyzer/human-readable-output

Proposed Solution

Implementation Details

1. Create src/output/human.rs module

   • Implement a HumanFormatter struct that implements the output formatter trait
   • Integrate with the output formatting framework

2. Table Formatting Features

   • Sort strings alphabetically or by other relevant criteria (offset, length, type)
   • Implement proper column alignment for readability
   • Support configurable column widths based on terminal size
   • Handle special characters and escape sequences properly
   • Provide headers for columns (e.g., Offset, Type, Value, Encoding)

3. Display Capabilities

   • Format extracted strings in a clean tabular layout
   • Support optional filtering (by string type, length, etc.)
   • Implement pagination for large result sets (optional enhancement)
   • Add summary statistics (total strings found, types breakdown)

Technical Approach

• Use Rust crate like prettytable-rs or comfy-table for table rendering
• Implement sorting using standard library sort methods with custom comparators
• Ensure UTF-8 handling for various string encodings
• Make formatter configurable via command-line flags or config file

Acceptance Criteria

• src/output/human.rs module created and integrated
• Table displays with proper column alignment and headers
• Results are sorted (default: alphabetically by string value)
• Special characters are properly escaped/displayed
• Unit tests cover:
  • Table formatting with various input sizes
  • Sorting functionality
  • Column alignment edge cases
  • Special character handling
• Documentation includes usage examples
• Integration with CLI argument parsing

Testing Requirements

• Unit tests for formatter implementation
• Integration tests with sample binary analysis output
• Edge case testing (empty results, very long strings, special characters)
• Performance testing with large result sets (>10k strings)

Dependencies

• Output Formatting Framework (blocking)
• Table rendering crate (e.g., comfy-table)
• CLI argument parsing framework

Related Issues

• Prerequisite: Output Formatting Framework implementation
• Future enhancement: Support for color-coded output based on string classification

Labels

• area:analyzer - Core analyzer functionality
• type:enhancement - New feature
• lang:rust - Rust implementation
• needs:tests - Requires comprehensive test coverage
• priority:medium - Important for v0.1 usability

## Requirements

- **Requirement ID**: 6.2
- **Blocked by**: Output Formatting Framework (must be implemented first)
- **Task ID**: stringy-analyzer/human-readable-output

## Proposed Solution

### Implementation Details

1. **Create \`src/output/human.rs\` module**
   - Implement a \`HumanFormatter\` struct that implements the output formatter trait
   - Integrate with the output formatting framework

2. **Table Formatting Features**
   - Sort strings alphabetically or by other relevant criteria (offset, length, type)
