**The Python documentation tool that developers actually want to use.**

PyCodeCommenter automatically generates, validates, and maintains Google-style docstrings for your Python code. Unlike AI-based tools, it provides **deterministic, rule-based validation** that catches documentation issues AI might miss.

## Why PyCodeCommenter?

### The Problem
-  AI tools generate inconsistent documentation
-  No way to validate existing docstrings against code
-  Documentation drift as code evolves
-  No coverage metrics for documentation quality

### The Solution
-  **Generate** professional docstrings automatically
-  **Validate** existing docs against actual code signatures
-  **Track** documentation coverage across projects
-  **Integrate** with CI/CD pipelines

### Terminal Usage
```bash
# Generate docstrings for a file
pycodecommenter generate main.py -i

# Validate documentation
pycodecommenter validate main.py

# Check project coverage
pycodecommenter coverage .
```

##  Features

### Comprehensive Validation
Six types of validation checks:
- **Signature Matching**: Params in code match docstring
- **Type Consistency**: Type hints match documented types
- **Exception Documentation**: Raised exceptions are documented
- **Return Documentation**: Return values properly documented
- **Format Compliance**: Follows Google-style guidelines
- **Content Quality**: No placeholders or TODOs

###  Coverage Reporting
- Per-file coverage metrics
- Project-wide statistics
- Export to JSON, Markdown, or console
- CI/CD integration ready

###  Modern Python Support
- Python 3.8+ support
- Async functions (`async def`)
- Complex type hints (`Union`, `Optional`, `Generic`)
- PEP 604 unions (`int | str`)
- PEP 585 generics (`list[int]`)

###  Developer-Friendly
- Beautiful console output
- Actionable error messages
- Multiple export formats
- Fast AST-based analysis (no API calls)

##  Usage Examples

### Example 1: Basic Generation
```python
from PyCodeCommenter import PyCodeCommenter

code = """
def calculate_discount(price: float, rate: float = 0.1) -> float:
    return price * (1 - rate)
"""

commenter = PyCodeCommenter().from_string(code)
docstrings = commenter.generate_docstrings()
print(commenter.get_patched_code())
```

**Output:**
```python
def calculate_discount(price: float, rate: float = 0.1) -> float:
    """Calculate discount.
    
    Calculates the discount.
    
    Args:
        price (float): Price of the object.
        rate (float): Rate of the object. (default: 0.1)
    
    Returns:
        float: Description of the return value.
    """
    return price * (1 - rate)
```

### Example 2: Validation in CI/CD
```python
# validate_docs.py
import sys
from PyCodeCommenter import PyCodeCommenter

commenter = PyCodeCommenter().from_file("src/main.py")
report = commenter.validate()

if report.stats.errors > 0:
    report.print_summary()
    sys.exit(1)  # Fail CI build

print(f"✓ Documentation validated: {report.stats.coverage_percentage:.1f}% coverage")
```

### Example 3: Coverage Enforcement
```python
from PyCodeCommenter import CoverageAnalyzer

analyzer = CoverageAnalyzer()
project = analyzer.analyze_directory("./src", exclude_patterns=['tests'])

if project.total_coverage < 80.0:
    print(f"❌ Coverage {project.total_coverage:.1f}% below threshold 80%")
    project.print_report()
    sys.exit(1)

print(f"✓ Coverage {project.total_coverage:.1f}% meets threshold")
```

### Example 4: Export Reports
```python
import json
from PyCodeCommenter import PyCodeCommenter

commenter = PyCodeCommenter().from_file("mycode.py")
report = commenter.validate()

# JSON export
with open("validation_report.json", "w") as f:
    json.dump(report.to_dict(), f, indent=2)

# Markdown export
with open("validation_report.md", "w") as f:
    f.write(report.to_markdown())
```

##  Configuration
Create `.pycodecommenter.yaml` in your project root:
```yaml
style: google  # or 'numpy', 'sphinx'
validation:
  level: strict  # or 'moderate', 'lenient'
  check_types: true
  check_exceptions: true
coverage:
  threshold: 80
  fail_below: true
exclude:
  - "*/tests/*"
  - "*/migrations/*"
  - "*/__pycache__/*"
```

##  Use Cases
### For Individual Developers
- Generate documentation for new functions quickly
- Validate docs before committing
- Track documentation coverage

### For Teams
- Enforce documentation standards in CI/CD
- Prevent PRs with undocumented code
- Maintain consistent documentation style

### For Open Source Projects
- Welcome contributors with clear doc requirements
- Automated documentation checks in PRs
- Public coverage badges

##  Integration

### Pre-commit Hook
```yaml
# .pre-commit-config.yaml
repos:
  - repo: local
    hooks:
      - id: validate-docstrings
        name: Validate Docstrings
        entry: pycodecommenter validate .
        language: system
        types: [python]
```

### GitHub Actions
```yaml
# .github/workflows/docs.yml
name: Documentation Check

on: [push, pull_request]

jobs:
  validate:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Set up Python
        uses: actions/setup-python@v2
        with:
          python-version: '3.9'
      - name: Install dependencies
        run: pip install pycodecommenter
      - name: Validate documentation
        run: pycodecommenter validate .
```
