cronably 1.3.1

Cronably allows you run python scripts with configured repetitions easily

CRONABLY

Introduction

Cronably allowsrun python scripts with configured repetitions easily. Every executed task under a job will let a register into an internal memory sqllite db . With simple changes in the configuration ( into the code or using an external file) you can change the way the cron interact with your code, including let the db as concrete db.

Let me show you some features

About How it Running

Cronably can run just configuring using annotations like this:

from cronably import Cronably

@Cronably(name="HOLA_MUNDO")
def my_process():
    print "Hola Mundo"

Or using an external file, it should be named "cronably.txt" , it should be allocated in the same path as the process:

from cronably.implementation import Cronably


@Cronably(ext_config=True)
def my_process_from_file():
    print "Hola Mundo"


if __name__ == '__main__':
    my_process_from_file()

And file should contains this:

name=HOLA_MUNDO

If you want to run from file, is mandatory to add always the param ext_config. If you add it all parameters will be taken from file. If you add here and also into the file, it will be overwritten by file's config values.

With this simple step you are telling to cronably that the method should run once. It's because the default parameter loop, by default is 1. The field "name" is mandatory.

About Loops

You can tell to cronably the times you want to repeat, (like a loop), with nothing, it will run only once If you configure:

@Cronably(name="HOLA_MUNDO", loops = 10)
def my_process():
    print "Hola Mundo"

It will run 10 times

But if you change it:

@Cronably(name="HOLA_MUNDO", loops = -1)
def my_process():
    print "Hola Mundo"

It will not stop running, until you kill the process

Loops and repetitions

Loops live together with repetitions, it means you can repeat the process every lapse of time, but if you configure an amount of times to do it, it will stop once you accomplish the quantity you configure there.

About Repetitions

Concrete elapse of times

Within the code:

@Cronably(name="HOLA_MUNDO", loops=10, repetition_frame= VALUE, repetition_period=15)
def my_process():
    print "Hola Mundo"

repetition_frame can be:

• HOURS
• MINUTES
• SECONDS
• DAYS

it will run 10 times every 15 MINUTES, from the moment you start the script

Within the file:

name=HOLA_MUNDO
loops=10
repetition.frame=HOURS
repetition.period=2

it will run 10 times the process every 2 HOURS

The repetitions will start from the moment you run the script.

Every Day, several times in specific hours

You should put as frame the value: DAILY

Within the code:

@Cronably( 
    name="HOLA_MUNDO", 
    loops=10, 
    repetition_frame= DAILY, 
    repetition_period='10:00,14:00,20:00' )
def my_process():
    print "Hola Mundo"

it will run 10 times every Day at 10:00, 14:00 and 20:00. Attention:

• It must be ordered from minus to Minor
• I'm using 0:00 to 23:59 style time.

Within the file:

name=HOLA_MUNDO
loops=10
repetition.frame=DAILY
repetition.period=10:00,14:00,20:00

Specific Days

You should put as frame the value: WEEKLY

Within the code:

@Cronably(name="HOLA_MUNDO", loops=10, repetition_frame= WEEKLY, repetition_period_day='Monday',repetition_period_time='10:00' )
def my_process():
    print "Hola Mundo"

It will run 10 times the process every Monday at 10:00 (AM) Attention: I'm using 0:00 to 23:59 style time.

Within the file:

name=HOLA_MUNDO
loops=10
repetition.frame=WEEKLY
repetition.period.day=Monday
repetition.period.time=10:00

It will run 10 times the process every Monday at 10:00 (AM)

The repetitions will start from the moment you run the script.

Specific Dates

TODO

About Reporting

when you setup reporting with Y ( default is N)

report='Y'

It will create, at the end of all loops some important information about your process, If you add some "print" commands to your process, it will also print those outputs, for your analysis if it where necessary.

Example of generated report

About Internal configure internal db for register

Cronably use for configuration and let some register SQLlite DB . By default it's a memory db, but you can configure to let it as concrete SQLlite DB so you can ask later about the process runned and their status.

Within the code:

@Cronably(name="HOLA_MUNDO", loops=10, db_kind='cronably', other configs... )
def my_process():
    print "Hola Mundo"

it will create a concrete sqllite into your folder script named cronably

Within the file:

name=HOLA_MUNDO
loops=10
db_kind=cronably
...

If you want to know how to access or read sqllite please read sqlLite Documentation

Clone and install locally

Build from sources

Steps once you clone it from https://gitlab.com/Kotlirevsky/cronably:

1.- build : run python setup.py sdist bdist_wheel.

It will create the lib cronably.X.X.X.tar.gz in dist folder.

2.- In your proyect , if you have pipenv run:

pipenv install cronably-1.0.0.tar.gz

3.- You can check this example running
