[![CI](https://github.com/user/pmat/workflows/CI/badge.svg)](https://github.com/user/pmat/actions)

A high-performance code analysis tool designed for large-scale projects.

## Features

- **Fast Analysis**: Process millions of lines of code in seconds
- **Intelligent Caching**: Smart caching system reduces repeated work
- **Plugin Architecture**: Extend functionality with custom plugins
- **Cross-Platform**: Works on Linux, macOS, and Windows
- **Real-time Monitoring**: Watch for changes and update analysis

## Architecture

PMAT is built on a modular architecture consisting of:

### Core Components

1. **Analysis Engine**: The heart of the system that processes code
2. **Cache Manager**: Handles intelligent caching of results
3. **Plugin System**: Allows third-party extensions

### Data Flow

```
Source Code → Parser → AST → Analyzer → Results → Output
                 ↓                           ↑
              Cache ←------------------------┘
```

## Installation

```bash
cargo install pmat
```

## Quick Start

```bash
# Analyze current directory
pmat analyze .

# Watch for changes
pmat watch --path ./src
```

## Configuration

Create a `.pmat.toml` file in your project root:

```toml
[analysis]
exclude = ["target", "node_modules"]
max_file_size = "10MB"

[cache]
enabled = true
ttl = 3600
```
