The `rad config` command is used to manage the local user configuration.
In its simplest form, `rad config` prints the current configuration.

```
$ rad config
{
  "publicExplorer": "https://app.radicle.xyz/nodes/$host/$rid$path",
  "preferredSeeds": [
    "z6MkrLMMsiPWUcNPHcRajuMi9mDfYckSoJyPwwnknocNYPm7@iris.radicle.xyz:8776"
  ],
  "web": {
    "pinned": {
      "repositories": []
    }
  },
  "cli": {
    "hints": true
  },
  "node": {
    "alias": "alice",
    "listen": [],
    "peers": {
      "type": "dynamic"
    },
    "connect": [],
    "externalAddresses": [],
    "network": "main",
    "log": "INFO",
    "relay": "auto",
    "limits": {
      "routingMaxSize": 1000,
      "routingMaxAge": 604800,
      "gossipMaxAge": 1209600,
      "fetchConcurrency": 1,
      "maxOpenFiles": 4096,
      "rate": {
        "inbound": {
          "fillRate": 5.0,
          "capacity": 1024
        },
        "outbound": {
          "fillRate": 10.0,
          "capacity": 2048
        }
      },
      "connection": {
        "inbound": 128,
        "outbound": 16
      },
      "fetchPackReceive": "500.0 MiB"
    },
    "workers": 8,
    "seedingPolicy": {
      "default": "block"
    }
  }
}
```

You can also get any value in the configuration by path, eg.

```
$ rad config get node.alias
alice
$ rad config get preferredSeeds
z6MkrLMMsiPWUcNPHcRajuMi9mDfYckSoJyPwwnknocNYPm7@iris.radicle.xyz:8776
$ rad config get node.limits.routingMaxSize
1000
```

You can set scalar values by path.

```
$ rad config set node.alias bob
bob
$ rad config get node.alias
bob
```

You can push a value to a collection by path.

```
$ rad config push web.pinned.repositories rad:z3TajuiHXifEDEX4qbJxe8nXr9ufi
rad:z3TajuiHXifEDEX4qbJxe8nXr9ufi
$ rad config push web.pinned.repositories rad:z3trNYnLWS11cJWC6BbxDs5niGo82
rad:z3TajuiHXifEDEX4qbJxe8nXr9ufi
rad:z3trNYnLWS11cJWC6BbxDs5niGo82
```

You can remove a value from a collection by path.

```
$ rad config remove web.pinned.repositories rad:z3TajuiHXifEDEX4qbJxe8nXr9ufi
rad:z3trNYnLWS11cJWC6BbxDs5niGo82
```

Values that are not strictly required for a working configuration, such as
optional values or additional user-defined values, can be deleted.

```
$ rad config set web.name alice
alice
$ rad config unset web.name
```

``` (fail)
$ rad config get web.name
✗ Error: web.name does not exist in configuration found at "[..]/.radicle/config.json"
```

Values along the path will be created if necessary.

```
$ rad config set value.a.future.update.might.add.value 5
5
$ rad config push value.a.future.update.might.add.collection 1
1
```

```
$ rad config push node.array a
a
$ rad config push node.array b
a
b
```

Values that are required for a valid config can't be deleted.

``` (fail)
$ rad config unset node.alias
✗ Error: writing configuration to "[..]/.radicle/config.json" failed: validation failure due to missing field `alias`
```

Values for changes are being validated.

``` (fail)
$ rad config set web.pinned.repositories 5
✗ Error: writing configuration to "[..]/.radicle/config.json" failed: validation failure due to invalid type: integer `5`, expected a sequence
```

The type of the operation is validated.

``` (fail)
$ rad config push node.alias eve
✗ Error: failed to modify configuration found at "[..]/.radicle/config.json" due to the element at the path 'node.alias' is not a JSON array
```
