### MicroWorkers is a class that easily manages a pool of threads to optimise simultaneous jobs and jobs endings, for MicroPython (used on ESP32 and [Pycom](http://www.pycom.io) modules)

![HC²](hc2.png "HC²")

Very easy to integrate and very light with one file only :

- `"microWorkers.py"`

Simple but effective :

- Use it to create a multitasking jobs container

- Add jobs without blocking your main code

- Be alerted by an event when a job has finished

### Using *microWorkers* class :

| Description  | Function |

| - | - |

| Constructor | `workers = MicroWorkers(workersCount, workersStackSize=None)` |

| Adds a job | `workers.AddJob(name, function, arg=None, onFinished=None)` |

| Description  | Property |

| - | - |

| Returns workers count | `workers.Count` |

| Returns emaining jobs count | `workers.JobsInQueue` |

| Returns jobs in process count  | `workers.JobsInProcess` |

| Returns `True` if is in working | `workers.IsWorking` |

### Simple example :

```python

from microWorkers import MicroWorkers

from time         import sleep

def sleepJob(jobName, jobArg) :

	sleep(10)

	return True

workers = MicroWorkers(workersCount=5)

for i in range(5) :

	workers.AddJob('Job %s' % i, sleepJob)

```

### Example of using multiple jobs (with finished event) :

```python

from microWorkers import MicroWorkers

from time         import sleep

print()

def jobA(jobName, jobArg) :

    sleep(1)

    return '%s:OK:1s' % jobName

def jobB(jobName, jobArg) :

    sleep(2)

    return '%s:OK:2s' % jobName

def jobC(jobName, jobArg) :

    sleep(3)

    return '%s:OK:3s' % jobName

def jobFinished(jobName, jobArg, jobResult) :

    print('Job %s finished (%s)' % (jobName, jobResult))

# workersStackSize must be greater than zero

# it can be None to use the default stack size

workers = MicroWorkers(workersCount=5, workersStackSize=10*1024)

for x in range(5) :

    workers.AddJob('JobA.%s' % x, jobA, arg=None, onFinished=jobFinished)

    workers.AddJob('JobB.%s' % x, jobB, arg=None, onFinished=jobFinished)

    workers.AddJob('JobC.%s' % x, jobC, arg=None, onFinished=jobFinished)

# Waiting end of all jobs,

while workers.IsWorking :

    sleep(0.100)

```
