Arg Cat Package

This is a package for read params from args and env.

How to Use

argcat.add_key("env")

This will find args -e or --env, or find environment ENV.

• Only read arg: argcat.from_arg()
• Only read environment: argcat.from_environ()
• Read both arg and environment: argcat.from_arg_and_environ()
• Remove arg: argcat.remove("env")

Example

from arg_cat import ArgCat

argcat = ArgCat()
argcat.add_key("env")
argcat.add_key("release", is_a_bool=True)
argcat.add_key("some_path", is_a_path=True)
argcat.from_arg_and_environ(environ_override_all=False)
print(f'env: {argcat.get_string("env")}')
print(f'release: {argcat.get_bool("release")}')
print(f'some_path: {argcat.get_string("some_path")}')

• This example will get 3 params, env, release and some_path.
• ArgCat will find -e or --env in args for env.
• ArgCat will find -r or --release in args for release.
• ArgCat will find -s or --some_path in args for some_path.
• ArgCat will find ENV in environment for env.
• ArgCat will find RELEASE in environment for release.
• ArgCat will find SOME_PATH in environment for some_path.
• from_arg_and_environ will using environment first, then using the args value to override those values. Sometimes, you may want to use environment value to override the args value, you should let environ_override_all to be Ture. environ_override_all default value is False.
• Running this will be like: python3 demo.py --env dev -r -s ./this/is/path

Situation 1

environ_override_all=False

Environment:

ENV=this is from env
RELEASE=False

Args:

--env "from arg" -s ./hello

Result:

env: from arg
release: False
some_path: YOUR_WORK_PATH/./hello

Situation 2

environ_override_all=True

Environment:

ENV=this is from env
RELEASE=False

Args:

--env "from arg" -s ./hello

Result:

env: this is from env
release: False
some_path: YOUR_WORK_PATH/./hello

Sync File

Default, we using ./params.json file to be the params file. sync_from_file will remove all of exist values, and load those params json file's values.

argcat = ArgCat(params_file='YOUR_CUSTOM_PARAMS_FILE.json')
argcat.sync_to_file()
argcat.sync_from_file()
