Base Index

Production-Grade Code Intelligence Platform

Base Index is a high-performance code indexing and analysis platform designed for extremely large codebases. It provides intelligent file indexing, complexity analysis, and visual insights through a modern web interface.

🚀 Key Features

Core Indexing Engine

• Handles millions of files - Tested with 1M+ files
• Parallel processing - 4-16 configurable workers for maximum throughput
• Incremental indexing - 10-100x faster on subsequent runs (only processes changed files)
• Memory efficient - Chunked processing keeps memory bounded regardless of codebase size
• Zero external dependencies - Uses only Python stdlib
• High performance - 1,000-10,000 files/second throughput

Industry-Grade Reporting 🆕

• SARIF reports - Static Analysis Results Interchange Format v2.1.0
• ISO/IEC compliance - ISO 25010 Quality, ISO 5055 Maintainability
• Quality metrics - Modularity, Reusability, Analyzability, Testability
• Data science exports - CSV, JSON Lines, statistical summaries
• Standards compliant - OWASP, CWE, international quality standards
• Enterprise ready - Compatible with GitHub Security, Azure DevOps, GitLab

Visual Intelligence

• Beautiful Angular UI - Modern, responsive dashboard
• Multiple view modes - Grid, Tree, and Heatmap visualizations
• Complexity analysis - Color-coded by complexity level (Low/Medium/High)
• File type distribution - Visual breakdown of codebase composition
• Real-time statistics - Total files, size, lines of code, and more

Developer Experience

• 3-line integration - Easy to add to any automation
• CLI support - Can run standalone from command line
• Export capabilities - JSON, CSV, JSON Lines, SARIF formats
• Persistent caching - Instant recovery with auto-save/load
• Content hashing - SHA256 for accurate change detection

🔧 Quick Start

Installation

# Clone the repository
git clone https://github.com/Artifact-Virtual/MAOS.git
cd MAOS

# Install Python dependencies (optional, for file watching)
pip install -r requirements.txt

Python CLI Usage

Basic indexing:

from base_index import BaseIndexer

# Create indexer
indexer = BaseIndexer("/path/to/codebase")

# Run indexing
stats = indexer.index()

# Print results
print(f"Indexed {stats['total_files']:,} files")
print(f"Total size: {stats['total_size']/(1024**2):.2f} MB")
print(f"Duration: {stats['duration']:.2f}s")

Advanced configuration:

indexer = BaseIndexer(
    root_dir="/massive/codebase",
    workers=16,                      # More workers for large codebases
    chunk_size=5000,                 # Larger chunks
    max_file_size=50 * 1024 * 1024, # 50MB limit
    enable_hashing=True,
    ignore_patterns=['*.log', 'temp_*']
)

stats = indexer.index()

Scheduled background indexing:

from base_index import ScheduledBaseIndexer

# Create scheduled indexer
indexer = ScheduledBaseIndexer(
    root_dir="/path/to/code",
    interval=300,    # Re-index every 5 minutes
    workers=4
)

# Start background indexing
indexer.start()

# ... your application continues running ...

# Access current index at any time
stats = indexer.get_stats()
files = indexer.search('controller')

# Stop when done
indexer.stop()

Command Line Usage

# Basic indexing
python base_index.py /path/to/codebase

# With options
python base_index.py /path/to/codebase -w 8 -o index.json -v

# Generate industry-grade reports (SARIF, ISO compliance, etc.)
python base_index.py /path/to/codebase -r ./reports

# Options:
#   -w, --workers N      Number of parallel workers (default: 4)
#   -o, --output FILE    Export to JSON file
#   -r, --reports DIR    Generate industry-grade reports to directory
#   -v, --verbose        Verbose logging

Industry-Grade Reporting

Base Index includes enterprise-level reporting capabilities that comply with international standards:

Generate all reports:

python base_index.py /path/to/codebase --reports ./reports

Or use the reporting module directly:

from base_index import BaseIndexer
from base_index_reporting import BaseIndexReporter

# Index codebase
indexer = BaseIndexer("/path/to/code")
stats = indexer.index()

# Convert to report format
file_entries = [
    {
        'path': entry.path,
        'size': entry.size,
        'type': entry.type,
        'loc': entry.loc,
        'hash': entry.hash
    }
    for entry in indexer._index.values()
]

# Generate all reports
reporter = BaseIndexReporter()
reports = reporter.generate_all_reports(stats, file_entries, "./reports")

# Reports generated:
#   - SARIF (Static Analysis Results Interchange Format v2.1.0)
#   - ISO/IEC 25010 Quality Compliance Report
#   - ISO/IEC 5055 Maintainability Metrics
#   - Statistical Analysis Summary
#   - CSV Data Export
