fejao-config-parser 0.0.9

A Python package for parsing configuration from various sources such as files, environment variables, and command-line arguments.

fejao-config-parser

This is a package for setting up the variables that you need to you on your project from a list of dictionaries.

I was tired of everytime that I needed to set a project that should have input/variables to be set from a configuration file, environment variables or from terminal to write this code again and again. Then the unit-test , lint, pep. And so on and on...

I hope that you also find this tiredsome work not needed anymore for using this package.

• To Do

  This package at the moment it's not finished yet, just trying to publish on pypi.org at the moment

  • Finish README_PACKAGE.md file (The one to be publish on pypi.org)
  • Add lint tests
  • Add pep tests
  • Add the uni-test
  • Document the code (for generating the mkdocs)
  • Add the package code to git
  • [] Add CI-CD for testing + building + publishing
  • [] Something else that for sure I forgot to put on this list

• Links

  • git repository
  • source code documentation

• Installing

  For using this package you need to install it with:

  pip install fejao-config-parser
  

  You can import it to your code with:

  from fejao_config_parser import my_config
  

• Configuration

  • Structure

    You need to set a list of dictionaries such as:

    example_vaviables = [
      {
        <VARIABLE_1_CONFIGURATION>
      },
      {
        <VARIABLE_2_CONFIGURATION>
      },
      ...
      ...
      ...
      {
        <VARIABLE_N_CONFIGURATION>
      }
    ]
    

  • Dictionary entry for a variable

    Dictionary keys for setting a variable are:

    • name
      • The name of the variable that will be accessed at your project
      • This key is required to be set.
    • type
      • The type of this variable to be set, it will type-cast it as the type set here.
      • This key is required to be set.
      • Possible type of variables:
        • string
        • bool
        • int
        • float
        • list
        • dict
    • default
      • The default value of the variable to be set if any other methods were parsed.
      • This key is required to be set.
    • env_name
      • The name of the environment variable that should be read.
      • This key is NOT required to be set.
    • terminal_help
      • The name of the environment variable that should be read.
      • This key is NOT required to be set.
    • terminal_name
      • The variable name to be read from terminal. Example: example_string, it can be parsed at the terminal like --example_string <VAR_VALUE>
      • This key is NOT required to be set.
    • terminal_name_short
      • The variable short name to be read from terminal. Example: es, it can be parsed at the terminal like -es <VAR_VALUE>
      • This key is NOT required to be set.

  • Example

    example_variables = [
        {
          "name": "example_string",
          "type": "string",
          "default": "default_string_value",
          "env_name": "EXAMPLE_STRING",
          "terminal_help": "Example of a string terminal variable.",
          "terminal_name": "example_string",
          "terminal_name_short": "es",
        },
        {
          "name": "example_bool",
          "type": "bool",
          "default": False,
          "terminal_help": "Example of a boolean terminal variable.",
          "terminal_name": "example_bool",
          "terminal_name_short": "eb",
        },
        {
          "name": "example_int",
          "type": "int",
          "default": 42,
          "env_name": "EXAMPLE_INT",
        },
        {
          "name": "example_float",
          "type": "float",
          "default": 4.2,
        },
        {
          "name": "example_list",
          "type": "list",
          "default": ["1", "2", "3"],
          "env_name": "EXAMPLE_LIST",
          "terminal_help": "Example of a list terminal variable.",
          "terminal_name": "example_list",
          "terminal_name_short": "el",
        },
        {
          "name": "example_dictionary",
          "type": "dict",
          "default": {"key1": "value1", "key2": "value2"},
          "env_name": "EXAMPLE_DICTIONARY",
          "terminal_help": "Example of a dictionary terminal variable.",
          "terminal_name": "example_dictionary",
          "terminal_name_short": "ed",
        },
    ]
    

• How to use it

  For calling the my_config function the possible keys are:

  • config

    • The list of dictionaries to be set as variables.
    • This key is required to be set.

  • config_file

    • The path of the configuration file to be used for reading the variables values.
    • This key is NOT required to be set.
    • Type of files that can be parsed:
      • yaml
      • json
      • toml
      • ini
        • Values should be set at the [default] section
        • Still don't know how till this date people keep using ini files.

  • description

    • Description of you project when running on terminal with the '--help' output.
    • This key is NOT required to be set.

  • debug

    • Boolean of setting up the output in terminal from the variables that were set using the package.
    • This key is NOT required to be set.

  • Example

    config = my_config(
      config=example_variables,
      config_file="/tmp/foo.yaml",
      description="My project is AMAZING and not done with vibe-coding",
      debug=True
    )
    

  • Accessing the variables

    For accessing the variables is easy as:

    from fejao_config_parser import my_config
    
    example_variables = [
        {
          "name": "example_string",
          "type": "string",
          "default": "default_string_value",
          "env_name": "EXAMPLE_STRING",
        }
    ]
    config = my_config(config=example_variables)
    
    print(f"example_string: {config.example_string}")
    ---> default_string_value
