# Migration Complete: vibe_check → pretty_little_summary

## ✅ All Changes Complete!

The library has been successfully renamed from `vibe_check` to `pretty_little_summary` with significantly improved output for built-in types.

---

## Quick Start

### Installation
```bash
cd /path/to/wut_check  # Note: directory name still shows old name
pip install -e .
```

### Basic Usage
```python
import pretty_little_summary as pls

# Configure (optional, for LLM mode)
pls.configure(openrouter_api_key="sk-or-...")

# Use it!
result = pls.describe(my_object, explain=False)  # Deterministic mode
result = pls.describe(my_object, explain=True)   # LLM mode
```

---

## What Changed

### 1. Package Rename
- **Package**: `vibe-check` → `pretty-little-summary`
- **Module**: `vibe_check` → `pretty_little_summary`
- **Import**: `import pretty_little_summary as pls`
- **Function**: `pls.describe()` (was `vibe.check()`)
- **Result Class**: `Description` (was `VibeCheck`)

### 2. Dramatically Improved Deterministic Output

#### Before (❌ Not Useful)
```python
vibe.check(data, explain=False)
# Output: builtins.dict | [via GenericAdapter]
# Output: builtins.list | [via GenericAdapter]
```

#### After (✅ Useful!)
```python
pls.describe(data, explain=False)
# Output: builtins.dict | Length: 3 | Keys: name, age, city | Sample: {name: str, age: int, city: str} | [via GenericAdapter]
# Output: builtins.list | Length: 10 | Element types: int | [via GenericAdapter]
```

### 3. Enhanced GenericAdapter

Now extracts rich metadata for:

**Dictionaries**:
```python
data = {'name': 'Alice', 'age': 30, 'active': True}
pls.describe(data, explain=False)
# builtins.dict | Length: 3 | Keys: name, age, active | Sample: {name: str, age: int, active: bool} | [via GenericAdapter]
```

**Lists**:
```python
numbers = [1, 2, 3, 4, 5]
pls.describe(numbers, explain=False)
# builtins.list | Length: 5 | Element types: int | [via GenericAdapter]
```

**Strings**:
```python
text = "This is a sample string..."
pls.describe(text, explain=False)
# builtins.str | Length: 55 | "This is a sample string..." | [via GenericAdapter]
```

**Custom Classes**:
```python
class User:
    def __init__(self):
        self.name = "Alice"
        self.email = "alice@example.com"

user = User()
pls.describe(user, explain=False)
# __main__.User | Attributes: email, name | [via GenericAdapter]
```

## Testing the Changes

### 1. Verify Installation
```bash
python examples/verify_installation.py
```

Expected output:
```
✅ pretty_little_summary is installed
✅ Basic check() works
✅ pretty_little_summary is properly installed and functional!
```

### 2. Run the Showcase
```bash
python examples/showcase.py
```

Shows improved output for all types!

### 3. Quick Test
```python
import pretty_little_summary as pls

# Test dict
data = {'name': 'Alice', 'age': 30, 'city': 'SF'}
print(pls.describe(data, explain=False).content)
# Output: builtins.dict | Length: 3 | Keys: name, age, city | Sample: {name: str, age: int, city: str} | [via GenericAdapter]

# Test list
numbers = [1, 2, 3, 4, 5]
print(pls.describe(numbers, explain=False).content)
# Output: builtins.list | Length: 5 | Element types: int | [via GenericAdapter]
```

## Example Outputs Comparison

### Built-in Types

| Type | Before | After |
|------|--------|-------|
| **Dict** | `builtins.dict \| [via GenericAdapter]` | `builtins.dict \| Length: 3 \| Keys: name, age, city \| Sample: {name: str, age: int, city: str} \| [via GenericAdapter]` |
| **List** | `builtins.list \| [via GenericAdapter]` | `builtins.list \| Length: 10 \| Element types: int \| [via GenericAdapter]` |
| **String** | `builtins.str \| [via GenericAdapter]` | `builtins.str \| Length: 55 \| "This is a sample..." \| [via GenericAdapter]` |
| **Custom** | `__main__.User \| [via GenericAdapter]` | `__main__.User \| Attributes: name, email, active \| [via GenericAdapter]` |

### Specialized Types (Unchanged - Already Good)

| Type | Output |
|------|--------|
| **Pandas** | `pandas.DataFrame \| Shape: (100, 5) \| Columns: a, b, c, d, e \| Types: a:int64... \| [via PandasAdapter]` |
| **NumPy** | (Uses GenericAdapter - shows attributes) |
| **Matplotlib** | `matplotlib.figure.Figure \| [via MatplotlibAdapter]` |

## Migration Checklist

If you have existing code using `vibe_check`:

- [ ] Uninstall old package: `pip uninstall vibe-check`
- [ ] Install new package: `pip install -e .`
- [ ] Update imports: `import vibe_check as vibe` → `import pretty_little_summary as pls`
- [ ] Update function calls: `vibe.check()` → `pls.describe()`
- [ ] Update class references: `VibeCheck` → `Description`
- [ ] Update environment variables: `VIBECHECK_*` → `WUTIS_*`
- [ ] Restart Jupyter kernels (if using notebooks)
- [ ] Test your code

---

## What Stayed the Same

✅ Two modes: `explain=True` (LLM) and `explain=False` (deterministic)
✅ OpenRouter integration
✅ 10+ specialized adapters (Pandas, Matplotlib, etc.)
✅ History tracking in Jupyter
✅ Configuration via `.env` or `configure()`
✅ All core functionality

---

## Next Steps

1. **Try the new output**: `python examples/showcase.py`
2. **Run notebooks**: `jupyter notebook examples/quick_start.ipynb`
3. **Test with your data**: Import and try with your own objects
4. **Enable LLM mode**: Add `OPENROUTER_API_KEY` to `.env`

## Support

For issues or questions:
- Check `examples/README.md` for troubleshooting
- Run `python examples/verify_installation.py` to diagnose issues
- Review `CHANGELOG.md` for all changes
