## What is it?
Nmstate is a library with an accompanying command line tool that manages
host networking settings in a declarative manner.
The networking state is described by a pre-defined schema.
Reporting of current state and changes to it (desired state) both conform to
the schema.

Nmstate is aimed to satisfy enterprise needs to manage host networking through
a northbound declarative API and multi provider support on the southbound.
NetworkManager acts as the main (and currently the only) provider supported.

## State example:

Desired/Current state example (YAML):
```yaml
interfaces:
- name: eth1
  type: ethernet
  state: up
  ipv4:
    enabled: true
    address:
    - ip: 192.0.2.10
      prefix-length: 24
    dhcp: false
  ipv6:
    enabled: true
    address:
    - ip: 2001:db8:1::a
      prefix-length: 64
    autoconf: false
    dhcp: false
dns-resolver:
  config:
    search:
    - example.com
    - example.org
    server:
    - 2001:4860:4860::8888
    - 8.8.8.8
routes:
  config:
  - destination: 0.0.0.0/0
    next-hop-address: 192.0.2.1
    next-hop-interface: eth1
  - destination: ::/0
    next-hop-address: 2001:db8:1::1
    next-hop-interface: eth1
```

## Basic Operations

Show eth0 current state (python/shell):

```python
import libnmstate

state = libnmstate.show()
eth0_state = next(ifstate for ifstate in state['interfaces'] if ifstate['name'] == 'eth0')

# Here is the MAC address
eth0_mac = eth0_state['mac-address']
```

```shell
nmstatectl show eth0
```

Change to desired state (python/shell):

```python
import libnmstate

# Specify a Linux bridge (created if it does not exist).
state = {'interfaces': [{'name': 'br0', 'type': 'linux-bridge', 'state': 'up'}]}
libnmstate.apply(state)
```

```shell
# use yaml or json formats
nmstatectl set desired-state.yml
nmstatectl set desired-state.json
```

Edit the current state(python/shell):
```python
import libnmstate

state = libnmstate.show()
eth0_state = next(ifstate for ifstate in state['interfaces'] if ifstate['name'] == 'eth0')

# take eth0 down
eth0_state['state'] = 'down'
libnmstate.apply(state)
```

```shell
# open current state in a text editor, change and save to apply
nmstatectl edit eth3
```
