# Etcd

A ruby client for [etcd](https://github.com/coreos/etcd)
## Installation

Add this line to your application's Gemfile:

    gem 'etcd'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install etcd

## Usage
### Create a client object
```ruby
client = Etcd.client # this will create a client against etcd server running on localhost on port 4001
client = Etcd.client(:port=>4002)
client = Etcd.client(:host=>'127.0.0.1', :port=>4003)
client = Etcd.client(:host=>'127.0.0.1', :port=>4003, :allow_redirect => false) # wont let you run sensitive commands on non-leader machines, default is true
```
### Set a key
```ruby
client.set('/nodes/n1', 1)
# with ttl
client.set('/nodes/n2', 2, 4)  # sets the ttl to 4 seconds
```
### Get a key
```ruby
client.get('/nodes/n2').value

```
### Delete a key
```ruby
client.delete('/nodes/n1')
```

### Test and set
```ruby
client.test_and_set('/nodes/n2', 2, 4) # will set /nodes/n2 's value to 2 only if its previous value was 4

```

### Watch a key
```ruby
client.watch('/nodes/n1') # will wait till the key is changed, and return once its changed
```

### List sub keys
