## Lua Bindings for [qless](https://github.com/seomoz/qless-core)
### Usage
#### Test job
```Lua
-- this is separate Lua module which export `perform` function
-- This function accept 2 args
-- 1 - QLessJob object
-- 2 - `done` callback. Function have to call this function
-- when job complete or fail.
local uv = require "lluv"
local function perform(job, done)
-- get work data
local i = job.data.counter
local t = job.data.interval
-- start async job
local timer = uv.timer():start(0, t, function(self)
print(job, '#', i) i = i - 1
if i == 0 then
self:close()
-- can just pass `done` as callback
return job:complete(done)
end
end)
-- to handle messages form server we can use EventEmitter API
job:on('lock_lost', function(self, event, data)
timer:close()
-- we do not need call `job:complete`/`job:fail` so just call `done`
-- we have not pass any error because worker class already know
-- that this job lost its lock so it just ignore any error.
done()
end)
end
return {
perform = perform
}
```
#### Worker
```Lua
local uv = require 'lluv'
local QLessWorkerSerial = require 'lluv.qless.worker.serial'
local worker = QLessWorkerSerial.new{
queues = {'test-queue'};
reserver = 'ordered';
concurent = 2;
}
worker:run()
uv.run()
```
#### Client
```Lua
local uv = require 'lluv'
local QLess = require 'lluv.qless'
local qless = QLess.new()
local queue = qless:queue('test-queue')
queue:put("myjobs.test", { counter = 10; interval = 1000 }, function(self, err, jid)
qless:close()
end)
uv.run()
```
