# mruby-vedis [](https://travis-ci.org/matsumoto-r/mruby-vedis)
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 dude@example.com"
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", "dude@example.com"]
```
## 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
```
