logos-cdi 1.1.0

The hackable dependency injection framework

logos_cdi

LogosCDI is a dependency injection tool that allows you to create extensible and maintainable applications

How to install

pip install logos_cdi

Basic usage

First you need to create an object of the Application class

from logos_cdi.application import Application

app = Application(
    modules=[

    ]
)

You may want to use some modules to improve productivity

from logos_cdi.application import Application
from logos_cdi.command import Commands

app = Application(
    modules=[
        Commands()
    ]
)

The Commands Module gives you a basis for creating commands to be executed in the terminal.

You can call it with:

$ logos
usage: logos [--app-url APP_URL] {} ...
logos: error: the following arguments are required: command

Create your own modules with commands

from logos_cdi.command import Commands, AbstractCommand, CommandModule

class TestCommand(AbstractCommand):

    def define_arguments(self, argument_parser):
        argument_parser.add_argument('--name', default='Anonymous')
        return super().define_arguments(argument_parser)

    def execute(self):
        return print('Hello', self.arguments.name)

class Tests(CommandModule, BaseModule):

    def define_commands(self):
        return {
            'test': Service(
                class_path='test_module.TestCommand',
                parameters={}
            )
        }

Add to your application

from logos_cdi.application import Application
from logos_cdi.command import Commands
from test_module import Tests

app = Application(
    modules=[
        Commands(),
        Tests()
    ]
)

$ logos
usage: logos [--app-url APP_URL] {test} ...
logos: error: the following arguments are required: command

$ logos test --help
usage: logos test [-h] [--name NAME]

options:
  -h, --help   show this help message and exit
  --name NAME

$ logos test
Hello Anonymous

$ logo test --name=foo
Hello foo
