## Overview

The PowerPoint Template System provides a high-level abstraction for creating business presentations with consistent styling, reusable components, and flexible templating. The system consists of three main components:

- **Template System**: High-level business presentation templates
- **DSL (Domain Specific Language)**: Declarative presentation definition
- **Component System**: Modular, reusable slide components

### Key Benefits

- **Consistency**: Standardized layouts and styling across presentations
- **Efficiency**: Rapid presentation creation using templates
- **Flexibility**: Customizable components and themes
- **Maintainability**: Centralized styling and configuration
- **Business Focus**: Pre-built templates for common business scenarios

## Quick Start Guide

### 1. Basic Presentation Creation

```python
from enhanced_business_dsl import BusinessDSLBuilder, BusinessTheme

# Create a simple presentation
presentation = (BusinessDSLBuilder()
    .set_metadata(
        title="My Business Presentation",
        author="John Smith",
        company="Acme Corp"
    )
    .set_theme(BusinessTheme.CORPORATE_BLUE)
    .add_title_slide()
    .add_content_slide(
        "overview",
        "Company Overview",
        "bullet_list",
        {"items": ["Founded in 2020", "50+ employees", "Global presence"]}
    )
    .add_thank_you_slide()
    .build())

# Export to XML
xml_output = presentation.to_xml()
```

### 2. Using Pre-built Templates

```python
from business_template_examples import BusinessTemplateExamples

# Create a quarterly business review
qbr = BusinessTemplateExamples.create_quarterly_business_review()

# Create a sales pitch
sales_pitch = BusinessTemplateExamples.create_sales_pitch_presentation()

# Create an investor pitch deck
investor_pitch = BusinessTemplateExamples.create_investor_pitch_deck()
```

### 3. Custom Component Layout

```python
from modular_components import ComponentLayout, HeaderComponent, ContentComponent

# Create custom layout
layout = ComponentLayout()
layout.add_component(HeaderComponent())
layout.add_component(ContentComponent())

# Export layout configuration
layout.export_layout("my_custom_layout.json")
```

## Template System

### Creating Custom Templates

```python
from template_system_design import BusinessPresentationTemplate, BusinessTheme

# Create custom template
template = BusinessPresentationTemplate(BusinessTheme.CORPORATE_BLUE, "my_template")

# Customize slide templates
custom_slide = SlideTemplate(
    header=HeaderTemplate(HeaderConfig(show_logo=True)),
    content=ContentTemplate(ContentConfig(layout_type=SlideLayout.TWO_COLUMN)),
    footer=FooterTemplate(FooterConfig(show_confidentiality=True))
)

template.add_custom_template("custom_slide", custom_slide)
```

### Component Configuration

```python
from modular_components import ComponentBounds, ComponentStyle

# Define component bounds (in inches)
bounds = ComponentBounds(
    left=0.5,    # Distance from left edge
    top=1.5,     # Distance from top edge
    width=9.0,   # Component width
    height=4.5   # Component height
)

# Define component styling
style = ComponentStyle(
    font_name="Calibri",
    font_size=14,
    font_color="#000000",
    font_bold=False,
    alignment="left",
    padding=0.1
)

# Create component
component = ContentComponent(
    component_id="main_content",
    bounds=bounds,
    style=style
)
```

### Layout Management

```python
from modular_components import ComponentLayout

# Create layout
layout = ComponentLayout(slide_width=10, slide_height=7.5)

# Add components
layout.add_component(header_component)
layout.add_component(content_component)
layout.add_component(footer_component)

# Auto-arrange in columns
layout.auto_layout_two_column()  # or auto_layout_three_column()

# Render layout
layout.render_layout(slide, slide_data)
```

## Best Practices

### 1. Template Design

#### Consistency
- Use consistent fonts, colors, and spacing across templates
- Maintain brand guidelines in all templates
- Standardize component positioning and sizing

#### Flexibility
- Design templates to accommodate various content lengths
- Provide multiple layout options for different content types
- Allow for customization without breaking the design

#### Accessibility
- Use sufficient color contrast for readability
- Choose legible font sizes (minimum 12pt for body text)
- Provide alternative text for images and charts

### 2. Content Organization

#### Structure
- Start with title slide and agenda
- Use section dividers for major topics
- End with thank you/contact slide

#### Content Flow
- Follow logical progression of ideas
- Use bullet points for key information
- Limit text per slide (6x6 rule: max 6 bullets, 6 words each)

#### Visual Hierarchy
- Use font sizes to establish importance
- Employ consistent spacing and alignment
- Leverage white space effectively

### 3. Code Organization

#### Modularity
```python
# Good: Modular approach
class CustomBusinessTemplate:
    def __init__(self):
        self.header_config = self._create_header_config()
        self.footer_config = self._create_footer_config()
        self.style_config = self._create_style_config()
    
    def _create_header_config(self):
        return HeaderConfig(show_logo=True, show_date=True)
```

#### Configuration Management
```python
# Good: External configuration
template_config = {
    "theme": "corporate_blue",
    "header": {"show_logo": True, "show_date": True},
    "footer": {"show_confidentiality": True},
    "style": {"font_name": "Calibri", "primary_color": "#1f4e79"}
}

# Load from JSON file
with open("template_config.json", "r") as f:
    config = json.load(f)
```

#### Error Handling
```python
# Good: Comprehensive error handling
def create_presentation(dsl_data):
    try:
        # Validate input data
        if not validate_dsl_data(dsl_data):
            raise ValueError("Invalid DSL data")
        
        # Create presentation
        presentation = generate_from_dsl(dsl_data)
        return presentation
        
    except ValueError as e:
        logger.error(f"Validation error: {e}")
        raise
    except Exception as e:
        logger.error(f"Unexpected error: {e}")
        raise
```

### 4. Performance Optimization

#### Lazy Loading
```python
# Good: Load templates only when needed
class TemplateLibrary:
    def __init__(self):
        self._templates = {}
    
    def get_template(self, name):
        if name not in self._templates:
            self._templates[name] = self._load_template(name)
        return self._templates[name]
```

#### Caching
```python
# Good: Cache expensive operations
from functools import lru_cache

@lru_cache(maxsize=128)
def load_theme_config(theme_name):
    # Expensive theme loading operation
    return load_theme_from_file(theme_name)
```

### 5. Testing Strategy

#### Unit Tests
```python
def test_business_dsl_builder():
    builder = BusinessDSLBuilder()
    presentation = (builder
        .set_metadata(title="Test", author="Test Author")
        .add_title_slide()
        .build())
    
    assert presentation.title == "Test"
    assert presentation.author == "Test Author"
    assert len(presentation.slides) == 1
```

#### Integration Tests
```python
def test_template_generation():
    template = TemplateLibrary.get_executive_summary_template()
    dsl = create_test_dsl()
    
    # Test that template can generate presentation
    result = generate_presentation(template, dsl)
    assert result is not None
    assert os.path.exists(result)
```

## Integration Guide

### Integrating with Existing Code

#### 1. Wrapper Approach
```python
class LegacyIntegrationWrapper:
    def __init__(self, legacy_generator):
        self.legacy_generator = legacy_generator
        self.template_system = EnhancedTemplateGenerator()
    
    def generate_with_template(self, template_name, data):
        # Convert template to legacy format
        legacy_data = self._convert_to_legacy_format(template_name, data)
        return self.legacy_generator.generate(legacy_data)
```

#### 2. Gradual Migration
```python
# Phase 1: Add template support alongside existing functionality
def generate_presentation(data, use_templates=False):
    if use_templates:
        return new_template_generator.generate(data)
    else:
        return legacy_generator.generate(data)

# Phase 2: Migrate specific presentation types
def generate_executive_summary(data):
    return template_generator.generate_executive_summary(data)

# Phase 3: Full migration
def generate_presentation(data):
    return template_generator.generate(data)
```

### Configuration Management

#### Environment-Specific Configurations
```python
# config/development.json
{
    "theme": "modern_minimal",
    "debug_mode": true,
    "template_cache": false
}

# config/production.json
{
    "theme": "corporate_blue",
    "debug_mode": false,
    "template_cache": true
}
```

#### Dynamic Configuration Loading
```python
import os
import json

def load_config():
    env = os.getenv("ENVIRONMENT", "development")
    config_file = f"config/{env}.json"
    
    with open(config_file, "r") as f:
        return json.load(f)
```

## Troubleshooting

### Common Issues

#### 1. Template Not Found
```
Error: Template 'custom_template' not found
Solution: Ensure template is registered in TemplateLibrary
```

#### 2. Invalid DSL Data
```
Error: Invalid data for component 'header'
Solution: Validate DSL data structure matches component requirements
```

#### 3. Component Rendering Errors
```
Error: Component bounds exceed slide dimensions
Solution: Check ComponentBounds values are within slide limits
```

#### 4. Theme Loading Issues
```
Error: Theme configuration not found
Solution: Verify theme files exist and are properly formatted
```

### Debugging Tips

#### Enable Debug Logging
```python
import logging

logging.basicConfig(level=logging.DEBUG)
logger = logging.getLogger(__name__)

# Add debug statements
logger.debug(f"Loading template: {template_name}")
logger.debug(f"Component bounds: {component.bounds}")
```

#### Validate Data Structures
```python
def validate_presentation_data(data):
    required_fields = ['title', 'slides']
    for field in required_fields:
        if field not in data:
            raise ValueError(f"Missing required field: {field}")
    
    for slide in data['slides']:
        validate_slide_data(slide)
```

#### Test with Minimal Data
```python
# Create minimal test case
minimal_dsl = (BusinessDSLBuilder()
    .set_metadata(title="Test")
    .add_title_slide()
    .build())

# Test template generation
try:
    result = generate_presentation(minimal_dsl)
    print("Success: Template generation working")
except Exception as e:
    print(f"Error: {e}")
```
