## ⚙️ Configuration

PraisonAI PPT supports persistent configuration stored in `~/.praisonaippt/config.yaml`. This eliminates the need to specify credentials and settings every time you run commands.

### Quick Setup

Initialize your configuration interactively:

```bash
praisonaippt --config-init
```

Or use the config command:

```bash
praisonaippt config init
```

### Configuration File Location

- **Path**: `~/.praisonaippt/config.yaml`
- **Format**: YAML (user-friendly, easy to edit)
- **Auto-created**: On first `--config-init` run

### Configuration Structure

```yaml
gdrive:
  credentials_path: ~/gdrive-credentials.json
  folder_id: null
  folder_name: Bible Presentations
  use_date_folders: false
  date_format: YYYY/MM

pdf:
  backend: auto
  quality: high
  compression: true

defaults:
  output_format: pptx
  auto_convert_pdf: false
  auto_upload_gdrive: false
```

### Configuration Options

#### Google Drive Settings (`gdrive`)

| Option | Description | Example |
|--------|-------------|---------|
| `credentials_path` | Path to service account JSON | `"~/gdrive-credentials.json"` |
| `folder_id` | Google Drive folder ID | `"1a2b3c4d5e6f7g8h9i0j"` |
| `folder_name` | Folder name (auto-creates if missing) | `"Bible Presentations"` |
| `use_date_folders` | Create date-based subfolders | `true` or `false` |
| `date_format` | Date folder format pattern | `"YYYY/MM"`, `"YYYY-MM"`, `"YYYY/MM/DD"` |

#### PDF Settings (`pdf`)

| Option | Description | Values |
|--------|-------------|--------|
| `backend` | PDF conversion backend | `"aspose"`, `"libreoffice"`, `"auto"` |
| `quality` | PDF quality | `"low"`, `"medium"`, `"high"` |
| `compression` | Enable image compression | `true`, `false` |

#### Default Behaviors (`defaults`)

| Option | Description | Values |
|--------|-------------|--------|
| `auto_convert_pdf` | Auto-convert to PDF | `true`, `false` |
| `auto_upload_gdrive` | Auto-upload to Google Drive | `true`, `false` |

### Using Configuration

Once configured, commands become simpler:

#### Without Configuration
```bash
praisonaippt -i verses.yaml \
  --upload-gdrive \
  --gdrive-credentials ~/gdrive-credentials.json \
  --gdrive-folder-name "Bible Presentations"
```

#### With Configuration
```bash
# Just this! Config handles the rest
praisonaippt -i verses.yaml --upload-gdrive
```

### Configuration Priority

Settings are applied in this order (later overrides earlier):

1. **Default values** (built-in)
2. **Configuration file** (`~/.praisonaippt/config.yaml`)
3. **Command-line arguments** (highest priority)

**Example:**
```bash
# Config has: "folder_name": "Bible Presentations"
# This command overrides it:
praisonaippt -i verses.yaml --upload-gdrive --gdrive-folder-name "Sunday Service"
```

### Configuration Commands

```bash
# Initialize configuration (interactive)
praisonaippt --config-init
praisonaippt config init

# Show current configuration
praisonaippt --config-show
praisonaippt config show

# Edit configuration manually (YAML is easy to edit!)
nano ~/.praisonaippt/config.yaml
vim ~/.praisonaippt/config.yaml
code ~/.praisonaippt/config.yaml
```

### Manual Configuration

Create `~/.praisonaippt/config.yaml` manually:

```bash
mkdir -p ~/.praisonaippt
cat > ~/.praisonaippt/config.yaml << 'EOF'
gdrive:
  credentials_path: ~/gdrive-credentials.json
  folder_name: Bible Presentations

pdf:
  backend: auto
  quality: high

defaults:
  auto_convert_pdf: false
  auto_upload_gdrive: false
EOF
```

**YAML Benefits:**
- ✅ No quotes needed for most values
- ✅ No commas or brackets
- ✅ Clean, readable format
- ✅ Easy to comment with `#`
- ✅ Indentation-based (like Python)

### Python API with Configuration

```python
from praisonaippt import create_presentation, load_config
from praisonaippt.gdrive_uploader import upload_to_gdrive

# Load configuration
config = load_config()

# Create presentation
data = load_verses_from_file("verses.yaml")
output = create_presentation(data)

# Upload using config credentials
if config.get_gdrive_credentials():
    result = upload_to_gdrive(
        output,
        credentials_path=config.get_gdrive_credentials(),
        folder_name=config.get_gdrive_folder_name()
    )
    print(f"Uploaded: {result['webViewLink']}")
```

### Configuration Examples

#### Example 1: Google Drive Only
```yaml
gdrive:
  credentials_path: ~/secrets/gdrive-creds.json
  folder_name: Church Presentations
```

#### Example 2: Auto-Convert to PDF
```yaml
pdf:
  backend: libreoffice
  quality: high
  compression: false

defaults:
  auto_convert_pdf: true
```

#### Example 3: Complete Automation
```yaml
gdrive:
  credentials_path: ~/gdrive-credentials.json
  folder_name: Bible Study

pdf:
  backend: auto
  quality: high

defaults:
  auto_convert_pdf: true
  auto_upload_gdrive: true
```

#### Example 4: With Date-Based Folders
```yaml
gdrive:
  credentials_path: ~/.praisonaippt/gdrive-credentials.json
  folder_name: Bible Presentations
  use_date_folders: true    # Creates subfolders like 2024/12
  date_format: YYYY/MM      # Format: YYYY/MM, YYYY-MM, YYYY/MM/DD, etc.

defaults:
  auto_upload_gdrive: true
```

**Result**: Files uploaded to `Bible Presentations/2024/12/presentation.pptx`

#### Example 5: With Comments (YAML supports comments!)
```yaml
# Google Drive Settings
gdrive:
  credentials_path: ~/gdrive-credentials.json  # Path to service account JSON
  folder_name: Bible Presentations             # Auto-creates if doesn't exist
  use_date_folders: false                      # Set to true for date organization
  date_format: YYYY/MM                         # Date folder pattern (YYYY/MM, YYYY/MM/DD, etc.)

# PDF Settings
pdf:
  backend: auto      # Options: aspose, libreoffice, auto
  quality: high      # Options: low, medium, high
  compression: true  # Reduce file size

# Automation
defaults:
  auto_convert_pdf: false     # Set to true for automatic PDF conversion
  auto_upload_gdrive: false   # Set to true for automatic upload
```

With this config, just run:
```bash
praisonaippt -i verses.yaml
# Automatically creates PPTX, converts to PDF, and uploads to Google Drive!
```

### Benefits of Configuration

✅ **No Repetition** - Set credentials once, use everywhere  
✅ **Faster Commands** - Less typing, fewer arguments  
✅ **Consistent Settings** - Same quality/backend every time  
✅ **Secure** - Credentials stored in home directory (not in commands)  
✅ **Flexible** - Override config with CLI args when needed

**Full Documentation**: [`docs/HIGHLIGHTS_FEATURE.md`](docs/HIGHLIGHTS_FEATURE.md)

### PPTX to JSON Extraction

Convert any `.pptx` file back into the praisonaippt JSON schema — the inverse of `create_presentation()`.

#### CLI

```bash
# Auto-named output
praisonaippt convert-json presentation.pptx

# Named output
praisonaippt convert-json presentation.pptx --json-output output.json

# Compact JSON
praisonaippt convert-json presentation.pptx --json-output out.json --no-pretty
```

#### Python API

```python
from praisonaippt import pptx_to_json

# In-memory dict
data = pptx_to_json("presentation.pptx")

# Save to file
pptx_to_json("presentation.pptx", output_path="output.json")

# Round-trip test
from praisonaippt import create_presentation
create_presentation(pptx_to_json("slides.pptx"), output_file="roundtrip.pptx")
```

> **Note**: `background_image` paths and highlight annotation numbers (❶❷) cannot be recovered from the PPTX binary. All other features are extracted losslessly.

**Full Documentation**: [`docs/pptx-to-json.md`](docs/pptx-to-json.md)

### Lazy Loading

Optional dependencies are loaded only when needed, providing:

- **Smaller Installation**: Core package has minimal dependencies
- **Faster Startup**: Only load what you use
- **No Import Errors**: Package works without optional features
- **Clear Feedback**: Helpful messages when features unavailable

#### Example

```python
from praisonaippt.lazy_loader import check_optional_dependency

if check_optional_dependency('google.oauth2.service_account'):
    # Google Drive upload available
    from praisonaippt.gdrive_uploader import upload_to_gdrive
    upload_to_gdrive('file.pptx', credentials_path='creds.json')
else:
    print("Install with: pip install praisonaippt[gdrive]")
```

## 🐛 Troubleshooting

### Common Issues

#### 1. "Command not found: praisonaippt"

**Solution:**
- Make sure you installed the package: `pip install praisonaippt`
- Check that your Python scripts directory is in PATH

#### 2. "File not found" error

**Solution:**
- Verify the JSON file exists
- Use absolute path if needed: `praisonaippt -i /full/path/to/verses.yaml`

#### 3. "Invalid JSON" error

**Solution:**
- Validate your JSON syntax using a JSON validator
- Ensure all quotes are properly closed
- Check that commas are in the right places

#### 4. Empty presentation

**Solution:**
- Verify your JSON has a "sections" array
- Check that verses array is not empty

#### 5. Import errors

**Solution:**
- Reinstall the package: `pip install --force-reinstall praisonaippt`
- Check that python-pptx is installed: `pip install python-pptx`

#### 6. PDF conversion fails

**Solution:**
- For Aspose: `pip install praisonaippt[pdf-aspose]`
- For LibreOffice: Install LibreOffice from [libreoffice.org](https://www.libreoffice.org/)
- Check backend with: `praisonaippt convert-pdf --help`

#### 7. Google Drive upload not available

**Solution:**
- Install dependencies: `pip install praisonaippt[gdrive]`
- Set up service account credentials (see [`docs/google-drive-upload.md`](docs/google-drive-upload.md))

## 💡 Tips

- Keep verse text concise for better readability
- Use consistent reference formatting (e.g., "Book Chapter:Verse (Version)")
- Organize verses into logical sections
- Test with a small JSON file first
- Use the template file as a starting point
- Check available examples with `--list-examples`
- Long verses are automatically split across multiple slides
- For PDF conversion, ensure Aspose.Slides or LibreOffice is installed
- Use `--pdf-backend auto` for automatic backend detection
- High quality PDFs create larger files but better visual quality
- For Google Drive upload, set up service account credentials first
- Use lazy loading to keep your installation lightweight
