GENERICORE

This is the python port of genericore, the generic information gathering framework.

Disclamer

The python-genericore and it's submodules are currently under HEAVY development and may suck balls in the current state. I appologize for that.

Submodules

Currently the python implementation has the following submodules

  • utils.py - a number of functions which define "common patterns" in all genericore plugins (e.g. commandline parser or unique-id generator)

Configurator

python-genericore provides a extensive configuration submodule whichs allows the modules to evaluate/mix and merge configuration files.

The class Configurable provides a basic functionality to load configuration into the variable config via load_conf. this can be used to merge two configurations.

In addition to that there is a Configurator class which provides basic functionality for parsing defaults. please see main.py of mail_proc how to use these two.

configure your own class

python-genericore provides the Configurator class which can be instanciated in order to do all your nasty configuration and argument parsing stuff.

In order to configure YOUR Object object you may want to do the following things:

  • derive your class from Configurable ( to have the load_conf magic ) a "config" member variable is now available with the config dictionary
  • implement populate_parser(parser) in this function you can add custom arguments to the command line parser (argparse is the weaopn of choice in Configurator)
  • implement eval_parser(args) do something with the then parsed arguments

These functions will be called by the Configurator when doing a configure for a list of modules (including your's)

Dependencies

  • simplejson
  • pika

Install

clone this repository

$ sudo ./setup install

Usage

Configurator

This is what you normally want to do when writing a new genericore module:

conf = gen.Configurator(PROTO_VERSION,DESCRIPTION)  
amqp = gen.auto_amqp()   
s = YourMagic()  

conf.configure([amqp,s])    #set up parser and eval parsed stuff

# start network connections, probably also for your Parser (e.g. backend)
amqp.create_connection()

def cb (ch,method,header,body):
  entry = s.process(json.loads(body))
  amqp.publish(json.dumps(entry))

amqp.consume(cb)
amqp.start_loop()

MongoConnect

You can derive YourMagic from the MongoConnect class for having a fresh database connection AND all the parser magic included. It looks like this:

MODULE_NAME = 'mail_proc'

MODULE_NAME='YourMagic'
DEFAULT_CONFIG = {
  MODULE_NAME : {
    "database" : {
      "collection" : "magic"
    }
  }
}

class YourMagic(MongoConnect): #MongoConnect derives from Configurable!

  def __init__(self,conf=None):
    MongoConnect.__init__(self,MODULE_NAME,DEFAULT_CONFIG)
    self.load_conf(conf)

  def process(self,mail):
    #insert your magic here
    return reply

  def populate_parser(self,parser): 
    MongoConnect.populate_parser(self,parser)
    # your configuration

  def eval_parser(self,parsed): 
    MongoConnect.eval_parser(self,parsed)
    # your config evaulation
