Easy Lua scripting for Redis

============================

Led makes managing Redis Lua scripts simple and easy. Features:

## Installing

```

gem install led

```

## How to use it

### Install scripts as Ruby methods:

```ruby

Led.add_script(:add, 'return tonumber(ARGV[1])+tonumber(ARGV[2])')

Led.add(12, 34) # => 46

```

### String interpolation for lua:

```ruby

Led.add_script(:interpolate, 'return "abc_#{ARGV[1]}"')

Led.interpolate('def') # => "abc_def"

```

### Shorthand for redis calls:

```ruby

Led.add_script(:set, 'SET(ARGV[1], ARGV[2])') # silly example, I know

# same as redis.call('set', ARGV[1], ARGV[2])

```

                          

### Reuse code by using includes:

```lua

-- helpers.lua

local function add(x, y)

  return x + y

end

```

```lua    

-- test.lua

__include 'helpers'

return add(ARGV[1], ARGV[2])

```

```ruby

Led.script_dir = '.' 

# once the script dir is set, scripts files are loaded automatically.

Led.test(1, 2) # => 3

```
