Typer Tools

Simple tools for Typer CLI

pip install typer-tools

Options Anywhere

Typer does not support making cli -v export and cli export -v work the same way. But we can handle:

from typer_tools import option

Verbose = option(False, '-v', '--verbose') # drop-in replacement for typer.Option

@app.callback()
def main(verbose: bool = Verbose):
  ...

@app.command()
def export(verbose: bool = Verbose):
  ...

Dependency Injection

Typer does not support dependency injection. But we can handle:

from typer_tools import Dependency

def parse_client(
  host: str = typer.Option(..., '--host', help='HTTP host'), # or our own `option`, plain better
  port: int = typer.Option(80, '--port', help='HTTP port'),
  token: str = typer.Option(..., '--token', help='Access token')
) -> Client:
  ...

dep = Dependency(parse_client)

@typer.command()
@dep.inject
def main(some_option: str, client: Client = dep.Depends()):
  ...
