This is a collection of utilities to use configuration files to set parameters for a typer CLI. It is useful for typer commands with many options/arguments so you don't have to constantly rewrite long commands. This package was inspired by phha/click_config_file and prototyped in this issue. It allows you to set values for CLI parameters using a configuration file.

$ pip install typer-config[all]

Note: that will include libraries for reading from YAML, TOML, and Dotenv files as well. Feel free to leave off the optional dependencies if you don't need those capabilities.

# Long commands like this:
$ my-typer-app --opt1 foo --opt2 bar arg1 arg2

# Can become this:
$ my-typer-app --config config.yml

You can use a decorator to quickly add a configuration parameter to your typer application:

import typer
from typer_config import use_yaml_config

app = typer.Typer()


@app.command()
@use_yaml_config()  # MUST BE AFTER @app.command()
def main(foo: FooType): ...


if __name__ == "__main__":
    app()

Your typer command will now include a --config CONFIG_FILE option at the command line.

Note: this package also provides @use_json_config, @use_toml_config, and @use_dotenv_config for those file formats. You can also use your own loader function and the @use_config(loader_func) decorator.

See the documentation for more examples using typer-config.
