# SocialMagic 🪄

A powerful Python library for social media content enhancement with three magical features:

- **Text Sentiment → Emoji** - Automatically add emojis based on text sentiment
- **Fake Image Detection** - Detect similar/manipulated images using perceptual hashing  
- **Micro Story Generator** - Generate engaging short stories for any theme

## 🚀 Installation

```bash
pip install socialmagic
```

Or install from source:

```bash
git clone https://github.com/socialmagic/socialmagic.git
cd socialmagic
pip install -r requirements.txt
pip install .
```

## 📖 Usage

### 1. Text Sentiment to Emoji (emojify)

Analyze text sentiment and automatically append appropriate emojis:

```python
from socialmagic import emojify

# Basic usage
result = emojify("I love this product!")
print(result)  # "I love this product! 😍"

result = emojify("This is terrible")
print(result)  # "This is terrible 😢"

result = emojify("It's okay, nothing special")
print(result)  # "It's okay, nothing special 😐"

# Custom emoji mapping
custom_emojis = {
    'positive': ['🎉', '🌟', '✨'],
    'negative': ['💔', '😞', '🌧️'],
    'neutral': ['🤔', '😶', '📝']
}

result = emojify("Amazing work!", emoji_map=custom_emojis)
print(result)  # "Amazing work! 🎉"
```

### 2. Fake/Manipulated Image Detection (fakebuster)

Detect similar images using perceptual hashing to identify potential fakes:

```python
from socialmagic import is_similar

# Compare two images with default 90% threshold
is_fake = is_similar("original.jpg", "suspicious.jpg")
print(f"Images are similar: {is_fake}")

# Custom threshold (0-100)
is_fake = is_similar("image1.jpg", "image2.jpg", threshold=85)
print(f"Images are 85%+ similar: {is_fake}")

# Get exact similarity percentage
from socialmagic.fakebuster import get_similarity_percentage
similarity = get_similarity_percentage("img1.jpg", "img2.jpg")
print(f"Similarity: {similarity}%")
```

### 3. Micro Story Generator (storygen)

Generate engaging short stories for any theme and protagonist:

```python
from socialmagic import generate_story

# Generate stories for different themes
thriller = generate_story("thriller", "Alice")
print(f"Thriller: {thriller}")

comedy = generate_story("comedy", "Bob")
print(f"Comedy: {comedy}")

inspiration = generate_story("inspirational", "Maria")
print(f"Inspirational: {inspiration}")

scifi = generate_story("sci-fi", "Captain Nova")
print(f"Sci-Fi: {scifi}")

# Unknown themes use generic templates
mystery = generate_story("mystery", "Detective Holmes")
print(f"Mystery: {mystery}")

# Get available themes
from socialmagic.storygen import get_available_themes
themes = get_available_themes()
print(f"Available themes: {themes}")

# Add custom templates
from socialmagic.storygen import add_custom_template
add_custom_template("horror", "As {protagonist} entered the abandoned house, the door slammed shut behind them...")

horror_story = generate_story("horror", "Sarah")
print(f"Horror: {horror_story}")
```

## 🎯 Features

### Emojify Module
- **Sentiment Analysis**: Uses VADER sentiment analysis for accurate emotion detection
- **Smart Emoji Selection**: Randomly selects from appropriate emoji sets
- **Custom Emoji Maps**: Define your own emoji collections for different sentiments
- **Multiple Languages**: Works with any text that VADER can analyze

### FakeBuster Module  
- **Perceptual Hashing**: Uses advanced image hashing for robust comparison
- **Adjustable Threshold**: Configure sensitivity from 0-100%
- **Error Handling**: Graceful handling of missing files and corrupted images
- **Batch Processing**: Compare multiple images efficiently

### StoryGen Module
- **Multiple Themes**: Built-in support for thriller, comedy, inspirational, and sci-fi
- **Flexible Templates**: Easy to add custom story templates
- **Random Selection**: Ensures variety in generated content
- **Generic Fallback**: Handles unknown themes gracefully

## 🌟 Examples

### Complete Social Media Enhancement

```python
from socialmagic import emojify, is_similar, generate_story

# Enhance a social media post
post_text = "Just finished my morning workout"
enhanced_post = emojify(post_text)
print(f"Enhanced post: {enhanced_post}")

# Check if an image is potentially fake
if is_similar("user_upload.jpg", "known_fake.jpg", threshold=90):
    print("⚠️ Potential fake image detected!")

# Generate engaging content
story = generate_story("inspirational", "fitness enthusiast")
print(f"Motivational story: {story}")
```

### Batch Image Analysis

```python
from socialmagic.fakebuster import is_similar, get_similarity_percentage
import os

def analyze_image_folder(folder_path, reference_image):
    results = []
    for filename in os.listdir(folder_path):
        if filename.lower().endswith(('.jpg', '.jpeg', '.png')):
            image_path = os.path.join(folder_path, filename)
            similarity = get_similarity_percentage(reference_image, image_path)
            results.append((filename, similarity))
    
    return sorted(results, key=lambda x: x[1], reverse=True)

# Find similar images
similar_images = analyze_image_folder("./images", "reference.jpg")
for filename, similarity in similar_images[:5]:
    print(f"{filename}: {similarity}% similar")
```
