| ---------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `int_input`      | **Error**: You must enter a valid integer.                                                                                                                                                                            |

| `decimal_input`  | **Error**: You must enter a valid Decimal.                                                                                                                                                                            |
| `datetime_input` | **Error**: You must enter a valid datetime in valid ISO 8601 format e.g. YYYY-MM-DD.<br>See [documentation](https://docs.python.org/3/library/datetime.html#datetime.datetime.fromisoformat) for all allowed options. |

Here's an updated README section to showcase how `typed_input` supports the same API as `input()`:

---

### Seamless Input API Compatibility

The `typed_input` library is designed to feel natural for Python developers by
supporting the same API as the standard [`input()`](https://docs.python.org/3/library/functions.html#input) function.

#### Example Usage (like [`input()`](https://docs.python.org/3/library/functions.html#input))
```python
>>> from typed_input import int_input
>>> x = int_input()
a
Error: You must enter a valid integer.
42
>>> type(x)
<class 'int'>
>>> x
42

>>> from typed_input import float_input
>>> x = float_input()
3.14
>>> type(x)
<class 'float'>

>>> from typed_input import decimal_input
>>> x = decimal_input()
1.45
>>> type(x)
<class 'decimal.Decimal'>

>>> from typed_input import datetime_input
>>> dt = datetime_input()
2024-01-01
>>> type(dt)
<class 'datetime.datetime'>
```

#### Example with a `prompt`
Just like [`input()`](https://docs.python.org/3/library/functions.html#input), you can also pass a `prompt` to guide the user:
```python
>>> from typed_input import int_input
>>> int_input('Enter a number: ')
Enter a number: 7
7
```

This compatibility makes `typed_input` a drop-in replacement for `input()` in 
many scenarios, with the added benefit of type safety and validation!

### More Examples Showing Range Validation

#### `int_input` for validated integer input
```python
>>> from typed_input import int_input
>>> int_input(prompt="Enter a number (1-10): ", min_value=1, max_value=10)
Enter a number (1-10): abc
Error: You must enter a valid integer.
Enter a number (1-10): 20
Error: Value must be between 1 and 10.
Enter a number (1-10): 5
5
```

#### `float_input` for validated floating-point input
```python
>>> from typed_input import float_input
>>> float_input(prompt="Enter a temperature (-50 to 50): ", min_value=-50.0, max_value=50.0)
Enter a temperature (-50 to 50): 
Error: You must enter a valid float.
Enter a temperature (-50 to 50): 100
Error: Value must be between -50.0 and 50.0.
Enter a temperature (-50 to 50): 22.5
22.5
```

#### `decimal_input` for validated decimal input
```python
>>> from typed_input import decimal_input
>>> from decimal import Decimal
>>> decimal_input(prompt="Enter a price (min 0.01): ", min_value=Decimal("0.01"))
Enter a price (min 0.01): -10
Error: Value must be at least 0.01.
Enter a price (min 0.01): 19.99
Decimal('19.99')
```

#### `datetime_input` for validated datetime input
```python
>>> from typed_input import datetime_input
>>> from datetime import datetime
>>> datetime_input(prompt="Enter a date (YYYY-MM-DD): ", min_value=datetime(2023, 1, 1))
Enter a date (YYYY-MM-DD): invalid
Error: You must enter a valid datetime in ISO 8601 format (e.g., YYYY-MM-DD).
Enter a date (YYYY-MM-DD): 2022-12-31
Error: Date must be on or after 2023-01-01.
Enter a date (YYYY-MM-DD): 2023-01-15
datetime.datetime(2023, 1, 15, 0, 0)
```
---

### ❌ Error Handling

All functions raise a `ValueError` for:
- **Invalid Range**: `min_value > max_value`.
- **Default Out of Bounds**: `default_value` outside `min_value`/`max_value`.

Example:
```python
>>> int_input(min_value=10, max_value=5)
Traceback (most recent call last):
  ...
ValueError: min_value (10) cannot be greater than max_value (5).
```

### 🛠️ Development

- Run formater: 
  - `uv run ruff check --select I --fix && uv run ruff format`
- Run type checking: 
  - `uv run mypy . `
- Run all unit tests:
  - `uv run typed_input_test.py`
- Run specific unit test:
  - `uv run python -m unittest int_input_test.py`
