## Features
- **Fluent Syntax**: Define validation rules in a clean and fluent manner.
- **No Extra Dependencies**: `fluent_validator` is lightweight and doesn't require any additional packages.
- **Python 3.7+ Support**: It works seamlessly with Python versions 3.7, 3.8, 3.9, 3.10, and 3.11.
- **Extensive Validation Library**: Check out our extensive list of available validations to cover all your validation needs.
## Installation
You can install `fluent_validator` using pip:
```bash
pip install fluent-validator
````
## Usage
Here's a quick example of how to use `fluent_validator`:
```python
from fluent_validator import validate, validate_all
# Validate a single value
validate(10).not_is_none().greater_than(5).not_equal(40)
# Or validate multiple values
validate_all(10, 100).not_is_none().greater_than(5).not_equal(40)
```
## Available Validations
`fluent_validator` offers a wide range of validations to suit your needs.
Notably, all validations have a corresponding negative form. Simply prefix the method with `not_`.
For example, the negative of `is_none()` is `not_is_none()`.
### Check out the full list of available above.
| Validation | Description |
| --- | --- |
| `between(min_vl, max_vl)` | Check if the object is within the specified range. |
| `contains_at_least(value)` | Check if the object (assumed to be iterable) contains at least the specified number of elements. |
| `contains_at_most(value)` | Check if the object (assumed to be iterable) contains at most the specified number of elements. |
| `contains_exactly(value)` | Check if the object (assumed to be iterable) contains exactly the specified number of elements. |
| `equal(value)` | Check if the object is equal to the specified value. |
| `greater_or_equal_than(value)` | Check if the object is greater than or equal to the specified value. |
| `greater_than(value)` | Check if the object is greater than the specified value. |
| `has_unique_values()` | Check if the object (assumed to be iterable) contains unique values. Note: This function assumes that the object's elements are hashable. |
| `is_bool()` | Check if the object is a boolean. |
| `is_callable()` | Check if the object is callable (e.g., a function or method). |
| `is_false()` | Check if the object is a boolean and has a value of False. |
| `is_in()` | Check if the object is in a collection of values. |
| `is_instance()` | Check if the object is an instance of one or more specified types. |
| `is_iterable()` | Check if the object is iterable. |
| `is_none()` | Check if the object is None. |
| `is_number()` | Check if the object is a number (int or float). |
| `is_string()` | Check if the object is a string. |
| `is_true()` | Check if the object is a boolean and has a value of True. |
| `less_or_equal_than(value)` | Check if the object is less than or equal to the specified value. |
| `less_than(value)` | Check if the object is less than the specified value. |
| `max(value)` | Check if the object is less than or equal to the specified maximum value. |
| `min(value)` | Check if the object is greater than or equal to the specified minimum value. |
