Python library for creating chainable data transformers.
## Installation
`pip install knex`
## Usage
```python
>>> from knex.parsers import *
>>>
>>> input_data = """
... Interface IP-Address OK? Method Status Protocol
... GigabitEthernet0/1 unassigned YES unset up up
... GigabitEthernet0/2 192.168.190.235 YES unset up up
... GigabitEthernet0/3 unassigned YES unset up up
... GigabitEthernet0/4 192.168.191.2 YES unset up up
... TenGigabitEthernet2/1 unassigned YES unset up up
... Virtual36 unassigned YES unset up up
... """
>>>
>>> pattern = r"\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b"
>>>
>>> end = (
Start(input_data)
> RegexExtractAll(pattern)
> GetIndex(0)
> Concat("", "/24")
> IpNetwork()
)
>>>
>>> print(end.result)
192.168.190.0/24
