## README

# ntc_rosetta

ntc_rosetta leverages [yangify](https://github.com/networktocode/yangify) to implement a set of "drivers" that can:

1. Transform network devices' native configuration/state into structured data that conform to YANG models
2. Transform data structures that conform to YANG models into network device's native configuration/data structures
3. Merge configurations

## Installing NTC Rosetta

### Pip Install

`pip install ntc-rosetta`

### Install From Source

- Clone ntc-rosetta (`git clone https://github.com/networktocode/ntc-rosetta.git`)
- cd into project root (`cd ntc-rosetta`)
- `pip install poetry`
- `poetry install`

## Ways to get started with NTC Rosetta

- Start Executing Jupyter Notebooks
- [Read the Docs](https://ntc-rosetta.readthedocs.io/en/latest/index.html)

### Start Executing Jupyter Notebooks

#### Step 1

Clone the repository:
`$ git clone https://github.com/networktocode/ntc-rosetta.git`

#### Step 2

Change directory into `ntc-rosetta`:
`$ cd ntc-rosetta`

#### Step 3

Build the containers:
`$ make build_test_containers`

#### Step 4

Start a container so you can run the Jupyter notebooks:
`$ make jupyter`

#### Step 5

Launch a browser and navigate to the following URL:
`http://127.0.0.1:8888/tree/docs/tutorials`

The same notebooks can be viewed without being interactive in the NTC Rosetta Read the Docs.

## Parsing

    >>> from ntc_rosetta import get_driver
    >>>
    >>> ios = get_driver("ios", "openconfig")
    >>> ios_driver = ios()
    >>> with open("data/ios/config.txt", "r") as f:
    >>>     config = f.read()
    >>> print(config)
    interface FastEthernet1
       description This is Fa1
       shutdown
       exit
    !
    vlan 10
       name prod
       no shutdown
       exit
    !
    vlan 20
       name dev
       shutdown
       exit
    !
    >>> parsed = ios_driver.parse(native={"dev_conf": config})
    >>> import json
    >>> print(json.dumps(parsed.raw_value(), indent=4))
