## 🚀 Quick Start

### Installation

```bash
# Install with all dependencies (including service mode)
pip install nlp2cmd[all]

# Or install specific components
pip install nlp2cmd[browser,nlp]  # Web automation + Polish NLP
pip install nlp2cmd[sql,shell]   # Database + system commands
pip install nlp2cmd[service]      # Service mode (FastAPI + Pydantic)
```

### Shell Emulation Mode

NLP2cmd provides full shell emulation capabilities for system commands:

```bash
# Interactive shell mode
nlp2cmd --interactive --dsl shell
nlp2cmd> list files in current directory
nlp2cmd> find files larger than 100MB
nlp2cmd> show running processes
nlp2cmd> exit

# Single query mode
nlp2cmd --dsl shell --query "list files in current directory"
# Output: ls -la .

# Execute immediately (run mode)
nlp2cmd --run "list files in current directory" --auto-confirm
# Executes: ls -la . with real output

# Polish language support
nlp2cmd --dsl shell --query "znajdź pliki .log większe niż 10MB"
# Output: find . -type f -name "*.log" -size +10MB -exec ls -lh {} \;

# Process management
nlp2cmd --dsl shell --query "uruchom usługę nginx"
# Output: systemctl start nginx

nlp2cmd --dsl shell --query "pokaż procesy zużywające najwięcej pamięci"
# Output: ps aux --sort=-%mem | head -10
```

### Setup External Dependencies

```bash
# Auto-setup Playwright browsers and cache
nlp2cmd cache auto-setup

# Manual setup
nlp2cmd cache install --package playwright
```

# Specific DSL
nlp2cmd --dsl sql --query "SELECT * FROM users WHERE city = 'Warsaw'"
nlp2cmd --dsl shell --query "Znajdź pliki .log większe niż 10MB"
nlp2cmd --dsl docker --query "Pokaż wszystkie kontenery"
nlp2cmd --dsl kubernetes --query "Skaluj deployment nginx do 3 replik"

# Web automation
nlp2cmd --dsl browser --query "otwórz https://example.com i wypełnij formularz"
nlp2cmd web-schema extract https://example.com
nlp2cmd web-schema history --stats

# With options
nlp2cmd --explain --query "Sprawdź status systemu"
nlp2cmd --auto-repair --query "Napraw konfigurację nginx"

# Interactive mode
nlp2cmd --interactive

### Python API Usage

#### Basic Usage (New Architecture)

```python
from nlp2cmd import (
    DecisionRouter,
    RoutingDecision,
    PlanExecutor,
    ExecutionPlan,
    PlanStep,
    ResultAggregator,
    OutputFormat,
    get_registry,
)

# Initialize components
router = DecisionRouter()
executor = PlanExecutor()
aggregator = ResultAggregator()

# Route a query
routing = router.route(
    intent="select",
    entities={"table": "users"},
    text="show all users",
    confidence=0.9,
)

if routing.decision == RoutingDecision.DIRECT:
    # Simple query - direct execution
    plan = ExecutionPlan(steps=[
        PlanStep(action="sql_select", params={"table": "users"})
    ])
else:
    # Complex query - use LLM Planner
    from nlp2cmd import LLMPlanner
    planner = LLMPlanner(llm_client=your_llm_client)
    result = planner.plan(intent="select", entities={}, text="...")
    plan = result.plan

# Execute and format results
exec_result = executor.execute(plan)
output = aggregator.aggregate(exec_result, format=OutputFormat.TABLE)
print(output.data)
```

#### HybridThermodynamicGenerator (Recommended)

```python
from nlp2cmd.generation import HybridThermodynamicGenerator

generator = HybridThermodynamicGenerator()

# Simple query → DSL generation
result = await generator.generate("Pokaż użytkowników")
# → {'source': 'dsl', 'result': HybridResult(...)}

# Optimization → Thermodynamic sampling
result = await generator.generate("Zoptymalizuj przydzielanie zasobów")
# → {'source': 'thermodynamic', 'result': ThermodynamicResult(...)}
```

### Multi-Step Plans with Foreach

```python
# Define a multi-step plan
plan = ExecutionPlan(steps=[
    PlanStep(
        action="shell_find",
        params={"glob": "*.log"},
        store_as="log_files",
    ),
    PlanStep(
        action="shell_count_pattern",
        foreach="log_files",  # Iterate over results
        params={"file": "$item", "pattern": "ERROR"},
        store_as="error_counts",
    ),
    PlanStep(
        action="summarize_results",
        params={"data": "$error_counts"},
    ),
])

# Execute with tracing
result = executor.execute(plan)
print(f"Trace ID: {result.trace_id}")
print(f"Duration: {result.total_duration_ms}ms")
```

### Legacy Usage (SQL Adapter)

```python
from nlp2cmd import NLP2CMD, SQLAdapter

# Initialize with SQL adapter
nlp = NLP2CMD(adapter=SQLAdapter(dialect="postgresql"))

# Transform natural language to SQL
result = nlp.transform("Pokaż wszystkich użytkowników z Warszawy")
print(result.command)  # SELECT * FROM users WHERE city = 'Warszawa';
```

## 🔍 Keyword Intent Detection

NLP2CMD uses a **robust multi-layered detection pipeline** that ensures reliable intent recognition even with typos, variations, or missing dependencies:

### Detection Pipeline (11 Layers)

1. **Text Normalization** - Polish diacritics, typo corrections, optional lemmatization
2. **Fast Path Detection** - Quick browser/search queries
3. **SQL Context Detection** - Identify SQL keywords
4. **SQL DROP Detection** - High-priority dangerous operations
5. **Docker Detection** - Explicit Docker commands
6. **Kubernetes Detection** - K8s-specific commands
7. **Service Restart Detection** - Service management priority
8. **Priority Intents** - Configured high-priority patterns
9. **General Pattern Matching** - Full keyword matching with confidence scoring
10. **Fuzzy Matching** - Optional rapidfuzz for typos (85% threshold)
11. **Final Fallback** - Always returns `unknown/unknown`

### Key Guarantees

✅ **Always works** - Final fallback ensures no method returns `None`  
✅ **Graceful degradation** - Missing dependencies don't break the pipeline  
✅ **Typo tolerance** - Built-in corrections + optional fuzzy matching  
✅ **Performance optimized** - Fast path and priority checks first  
✅ **Safety first** - Dangerous operations get highest priority  

### Example Flow

```text
Input: "dokcer ps" (typo)
1. Normalization: "dokcer" → "docker"
2. Pattern matching: "docker ps" → docker/list
Result: ✅ Works without fuzzy matching
```

## 📋 Action Registry

```python
from nlp2cmd import get_registry

registry = get_registry()

# List all domains
print(registry.list_domains())
# ['sql', 'shell', 'docker', 'kubernetes', 'utility']

# List actions by domain
print(registry.list_actions(domain="sql"))
# ['sql_select', 'sql_insert', 'sql_update', 'sql_delete', 'sql_aggregate']

# Get destructive actions (require confirmation)
print(registry.get_destructive_actions())
# ['sql_insert', 'sql_update', 'sql_delete', 'docker_run', ...]

# Generate LLM prompt with available actions
prompt = registry.to_llm_prompt(domain="sql")
```

## 🛡️ Safety

The framework enforces safety at multiple levels:

1. **Action Allowlist**: Only registered actions can be executed
2. **Parameter Validation**: Full type checking and constraints
3. **Plan Validation**: All plans validated before execution
4. **No Code Generation**: LLM only produces JSON plans, not executable code
5. **Destructive Action Marking**: Actions that modify state are flagged

## 🧪 Testing

```bash
# Run all tests
pytest tests/ -v

# Run E2E tests for service mode
python3 run_e2e_tests.py

# Run specific component tests
pytest tests/unit/test_router.py -v
pytest tests/unit/test_registry.py -v
pytest tests/unit/test_executor.py -v

# Service mode E2E tests
pytest tests/e2e/ -m service

# With coverage
pytest --cov=nlp2cmd --cov-report=html
```

## 🔬 Thermodynamic Optimization (v0.3.0+)

Based on [Whitelam (2025) "Generative thermodynamic computing"](https://arxiv.org/abs/2506.15121), the framework now includes thermodynamic optimization for complex constraint satisfaction problems.

### Key Features

- **Langevin Dynamics Sampling**: Natural evolution from noise to structured solutions
- **Energy-Based Models**: Domain-specific constraint functions
- **Hybrid Routing**: Automatic selection between DSL generation and thermodynamic optimization
- **Energy Efficiency**: 50-70% reduction vs pure LLM inference

### Quick Example

```bash
nlp2cmd "Zaplanuj 5 zadań w 10 slotach z ograniczeniami" --explain
```

This command triggers thermodynamic optimization for constraint satisfaction problems and outputs results in YAML format, including energy estimates and scheduling solutions.

### Supported Problem Types

- **Scheduling**: Task scheduling with deadlines and constraints
- **Resource Allocation**: Optimal distribution under capacity limits  
- **Planning**: Multi-step planning with constraint satisfaction
- **Optimization**: General constrained optimization problems

See [Thermodynamic Integration](THERMODYNAMIC_INTEGRATION.md) for detailed documentation.
