Binding vedis for mruby.

Vedis is a embeddable datastore and self-contained C library that supports over 70 commands similar to Redis.

The major difference from Redis is no networking layer since Vedis runs in the same process of the host application.

Please see the official [Vedis homepage](http://vedis.symisc.net/index.html) for more detail.

## Install by mrbgems

Add the following line to `build_config.rb`:

```ruby

MRuby::Build.new do |conf|

    # ... (snip) ...

    conf.gem :github => 'matsumoto-r/mruby-vedis'

end

```

## Usage

```ruby

# In-Memory

v = Vedis.new

# On-Disk

# v = Vedis.new "/path/to/vedis.db"

# sym ok

v["test"] = "bbb"

v[:hoge] = 2

v[:foo] = 3

v.set :fuga, "aaa"

# exec

r1 = v.exec "MSET username james age 27 mail [email protected]"

r2 = v.exec "MGET username age mail"

p v["test"]     #=> "bbb"

p v[:hoge]      #=> "2"

p v["foo"]      #=> "3"

p v.get :fuga   #=> "aaa"

p r1            #=> nil

p r2            #=> ["james", "27", "[email protected]"]

```

## Benchmark comparing Vedis with Redis

### Simple benchmark

```ruby

class SimpleBenchmark

  def initialize(width = 0)

    @width = width

  end

  def measure(label)

    start = Time.now

    yield if block_given?

    passed = Time.now - start

    puts "#{make_fixed_label(label)}passed time #{passed} sec"

  end

  def make_fixed_label(label)

   if @width - label.length > 0

      label + ' ' * (@width - label.length)

    else

      label

    end

  end

end

benchmark = SimpleBenchmark.new

r = Redis.new "127.0.0.1", 6379

v = Vedis.new

n = 100000

[r, v].each do |kvs|

  benchmark.measure("#{kvs.class}: ") do

    n.times do |t|

      kvs.set t.to_s, t.to_s

    end

  end

end

r.close

v.close

```

### Results

```bash

$ mruby test_vedis_redis.rb

Redis: passed time 10.785598 sec

Vedis: passed time 0.06595 sec

```
