## Usage

### lluv client

```Lua

local cli = redis.Connection.new()

cli:open(function(cli)

  cli:ping(print)

  cli:quit(print)

end)

```

### basic transaction

```Lua

cli:open(function()

  cli:multi(function(cli, err, data) -- begin transaction

    -- We can cat IO/redis error

    -- if we get redis error that means application error

    -- try nested transaction or transaction in SUBSCRIBE mode

    -- so application shoul fix it.

    assert(not err or err:cat() ~= 'REDIS')

  end)

  -- we can proceed each command in separate callback

  cli:set("a", "10", function(cli, err, data)

    print("SET:", data)

  end)

  cli:ping() --or we can ignore callback

  cli:exec(function(cli, err, res)   -- end transaction

    -- and proceed all results in transaction

    for k, v in ipairs(res) do print("CMD #" .. k, v) end

  end)

  cli:quit()

end)

```

### pipeline

```lua

-- new pipeline

p = cli:pipeline()

  :set(a, 10)

  :set(b, 20)

-- execute and preserve pipeline

p:execute(true)

-- append command

p:set(c, 30)

-- and execute it again

p:execute() -- execute and clear

p -- set new commands and execute

  :set(a, 20)

  :set(b, 30)

  :execute()

```
