Shared

The libretime_shared package contains reusable functions and classes for the LibreTime project.

Usage

This library assumes that:

  • You will use Click to build a CLI for your app.
  • You will use Loguru to log messages from your app.
  • You will use Pydantic to validate objects in your app.

Configuration

First define a schema for your configuration in order to validate it. A schema is a class that inherit from pydantic.BaseModel. Some existing schemas can be reused such as libretime_shared.config.RabbitMQ or libretime_shared.config.Database.

Load your configuration using a subclass of libretime_shared.config.BaseConfig.

from pydantic import BaseModel

from libretime_shared.config import RabbitMQConfig, BaseConfig

class AnalyzerConfig(BaseModel):
    bpm_enabled: bool = False
    bpm_track_max_length: int

class Config(BaseConfig):
    rabbitmq: RabbitMQConfig
    analyzer: AnalyzerConfig

config = Config("/etc/libretime/config.yml")

Don't instantiate a sub model if it has a required field, otherwise the Config class import will raise a ValidationError.

CLI

Decorate your CLI commands with the shared decorators to add extra flags.

import click
from libretime_shared.cli import cli_logging_options, cli_config_options

from .app import App

@click.group()
def cli():
    pass

@cli.command()
@cli_config_options()
@cli_logging_options()
def run(**kwargs):
    app = App(**kwargs)
    return app.run()
