The ECiDA-python to make things easier

ECIDA

The EcidaModule package is a Python module designed to facilitate deployment and communication between components in a distributed system. This package provides various functionalities including Kafka message handling, environment variable checking, and directory management.

How to Use

1. Importing the package

   To use the EcidaModule in your Python program, first, you will need to import the EcidaModule class from the package:

   from Ecida import EcidaModule
   

2. Create an ECiDA Module

   Define a module with this signature

   def create_module() -> EcidaModule:
       M = EcidaModule("MODULE_NAME", "MODULE_VERSION")
       # ADD MODULE INPUTS/OUTPUTS HERE
       ...
   return M
   

3. Add inputs and outputs

   Use the following syntax for adding input and output to module. You can add as many I/O as required.

   # ADD STREAMING INPUT WITH 
   M.add_input("INPUT_NAME", "string")
   # ADD STREAMING OUTPUT 
   M.add_output("OUTPUT_NAME", "string")
   # ADD INPUT DIRECTORY FOR FILE USE 
   M.add_input_directory("INPUT_DIRECTORY_NAME")
   # ADD OUTPUT DIRECTORY FOR FILE USE 
   M.add_output_directory("OUTPUT_DIRECTORY_NAME")
   # ADD INPUT DIRECTORY PRELOADING FROM GIT FOR FILE USE
   M.add_input_from_git("INPUT_DIRECTORY_NAME", "GIT_REPOSITORY", "DIRECTORY/PATH/IN/GIT")
   

4. Entry Point

   Use the following boiler-plate as the entry-point to your code.

   if __name__ == "__main__":
       M = create_module()
       M.initialize()
       main(M)
   

   and for the main function use the following signature:

   def main(M: EcidaModule):    
       #YOUR LOGIC COMES HERE
   

Example python file

An example template for the modules.

from Ecida import EcidaModule

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)


def create_module() -> EcidaModule:
    M = EcidaModule("MODULE_NAME", "MODULE_VERSION")
    # ADD MODULE INPUTS/OUTPUTS HERE

    return M

def main(M: EcidaModule):    
    print(f"START MODULE {M.name}:{M.version}")
    # LOGIC COMES HERE
      


if __name__ == "__main__":
    M = create_module()
    M.initialize()
    main(M)

NOTES

A python file can contain no more than one one module, since the module creation happens through using create_module() function with exact same signature.
