## ✨ Overview

**MindDict** is a lightweight Python package that extends the built-in `dict` with practical utilities for data manipulation.  
It makes your dictionaries more expressive, readable, and fun to use — all without dependencies.

💡 Ideal for:
- data manipulation and transformation
- JSON serialization/deserialization
- configuration management
- clean, functional-style programming

---

## 🚀 Installation

```bash
pip install minddict
````

or from TestPyPI (for development builds):

```bash
pip install -i https://test.pypi.org/simple/ minddict
```

---

## 🧩 Quick Start

```python
from minddict import MindDict

data = MindDict(a=1, b=2, c=3)

# 🔍 Filter values
filtered = data.filter(lambda k, v: v > 1)
print(filtered)
# → MindDict(b=2, c=3)

# 🔄 Transform keys and values
mapped = data.map(lambda k, v: (k.upper(), v * 10))
print(mapped)
# → MindDict(A=10, B=20, C=30)

# 💾 Serialize to JSON
print(data.to_json(indent=2))
# {
#   "a": 1,
#   "b": 2,
#   "c": 3
# }

# 🧠 Invert keys and values
print(data.invert())
# → MindDict({1: 'a', 2: 'b', 3: 'c'})
```

## ⚙️ Features

| Method                       | Description                                                                |
| ---------------------------- | -------------------------------------------------------------------------- |
| `.filter(fn)`                | Keep items where `fn(key, value)` is `True`.                               |
| `.map(fn)`                   | Transform each key/value pair via `fn(key, value) → (new_key, new_value)`. |
| `.invert()`                  | Swap keys and values (last wins on conflicts).                             |
| `.diff(other, strict=False)` | Compare two dicts and get differences.                                     |
| `.merge(other)`              | Combine two dicts without mutating the originals.                          |
| `.flatten(separator=".")`    | Convert nested dicts into flat key paths.                                  |
| `.unflatten(separator=".")`  | Rebuild nested structure from flattened keys.                              |
| `.to_json(indent=0)`         | Serialize into JSON string.                                                |
| `.from_json(string)`         | Load from a JSON string.                                                   |

## 🧪 Examples

### 🔹 Filtering

```python
data = MindDict(name="Alice", age=25, city="Paris")
adults = data.filter(lambda k, v: k == "age" and v >= 18)
print(adults)
# MindDict(age=25)
```

### 🔹 Mapping

```python
data = MindDict(x=1, y=2)
result = data.map(lambda k, v: (k.upper(), v ** 2))
# MindDict(X=1, Y=4)
```

### 🔹 Flatten & Unflatten

```python
nested = MindDict({
    "user": {"name": "Bob", "info": {"city": "Paris", "age": 30}},
    "active": True
})

flat = nested.flatten()
# MindDict({'user.name': 'Bob', 'user.info.city': 'Paris', 'user.info.age': 30, 'active': True})

rebuilt = flat.unflatten()
# MindDict({'user': {'name': 'Bob', 'info': {'city': 'Paris', 'age': 30}}, 'active': True})
```

### 🔹 Diff & Merge

```python
a = MindDict(a=1, b=2)
b = MindDict(b=3, c=4)

print(a.diff(b))
# MindDict({'b': (2, 3), 'c': (None, 4)})

print(a.merge(b))
# MindDict({'a': 1, 'b': 3, 'c': 4})
```

## 🧩 Design Principles

* Pure functional methods — never mutate the original instance
* Always return a new `MindDict`
* Clean, explicit, Pythonic code
* Zero dependencies (only standard library)
