aiSSEMBLE Universal Config Loader

aiSSEMBLE Universal Config Loader uses Krausening to provide features to read the configuration from property file and load the configuration to environment variables or to global variables. For the notebook user, it also providers a helper class to extract their notebooks global variables into the property file to set up the configuration for the first time.

Getting Started

Notebook User

For the notebook user, to have an easy start, config helper provides a feature to extract the string type or int type global variables into the configuration property file. The configuration file will be created if it doesn't exist.

Example of Extract variables to the property file

The Following example shows how a notebook user can extract the variables from a cell to the property file

# a notebook cell
import os

# variables
test_var1="value_1"
test_var2="value_2"
test_var3="value_3"
test_var4=[1, 2, 3]  # the list variable will not be extracted to property file
test_var5={"a":"b", "c":"d"} # the dict variable will not be extract to property file
os.environ['PROJECT_ID'] = "test-final"
os.environ['ISSUE_ID']="1"

# install the aissemble-universal-config-loader module 
!pip install aissemble-universal-config-loader

# register the `aissemble_universal_config_loader.ipython.config_helper` ipython extension
%load_ext aissemble_universal_config_loader.ipython.config_helper

#extract the `int` type or `string` type global variables to the configuration file
%extract_vars_to_property_file

Output

After run above cell, expect the next steps printed in the cell output:

The next step contains:

1. The function to load property values as global variables
2. The configuration file location and what variables have been saved

****************************************************************************************
 Next Steps:
****************************************************************************************
 1: Required
----------------------------------------------------------------------------------------
 To load property values as global variables, add the below code snippets to a new cell and run the cell:

"""
# import the ConfigLoader module
from aissemble_universal_config_loader.config_loader import ConfigLoader

# set configuration file directory, this is for bootstrapping the library
os.environ['KRAUSENING_BASE'] = '/path-to-project-directory/configurations/base'

# load property values as global variables
ConfigLoader().load_as_global()
"""

 Note: Use `ConfigLoader().load_as_env()` to load property values as environment variable.


----------------------------------------------------------------------------------------
 2: Optional
----------------------------------------------------------------------------------------
 The variables have been extracted to /Users/csun/bah/tests/aissemble-lite-test/test-4306-3/backend/configurations/base/configuration.properties.
 You can remove the following variables from your notebook and load them via the ConfigLoader:
 ['test_var1=value_1', 'test_var2=value_2', 'test_var3=value_3']

Property file

If there is no existing property file, by default, the configuration.properties will be generated at the *.ipynb file's sibling directory configurations/base with the below content

test_var1=value_1
test_var2=value_2
test_var3=value_3

Python Project User

Installation

Add the aissemble-universal-config-loader package to your project

Load Property

To load the property, ensure the configuration.properties file is already generated. The loader uses Krausening to read properties from a properties file into either global variables or environment variables. The default Krausening base location is configurations/base and the default properties file is configuration.properties

Add import Statement

from aissemble_universal_config_loader.config_loader import ConfigLoader

Set Krausening_Base environment variable

Krausening is useful for defining different configurations per execution environment. For simple local usage, you can simply set KRAUSENING_BASE to the directory that contains your configuration file(s). For more detail: https://github.com/TechnologyBrewery/krausening/tree/dev/krausening#krausening-in-one-pint-learn-krausening-in-2-minutes

os.environ['KRAUSENING_BASE']="path-to-property-directory"

Load Property to Global Variables

 ConfigLoader().load_as_global()

Load Property to Environment Variables

 ConfigLoader().load_as_env()
