Python click getting default values from config file
Found a post1 about it.
But I like much more Click’s way to do this (Options — Click Documentation (8.0.x)):
@click.option(
"--username", prompt=True,
default=lambda: os.environ.get("USER", "")
)
Of course, os.get.environ can be replaced by python-decouple’s config().
Lastly, ini files support interpolation2 (%(whatever)s)! Final solution:
[settings]
EXPORT=../../exports
CATS_INPUT=%(EXPORT)s/cats.json
@click.option(
"--input-file",
"-i",
type=click.Path(exists=True, path_type=Path),
default=lambda: config("CATS_INPUT"),
)
Also TIL if I use quotes in the ini file, they’ll become part of the final filename.
Nel mezzo del deserto posso dire tutto quello che voglio.
