pytomlenv

Environment in TOML for Python.

Install

pip install pytomlenv

Usage

.env.toml

[production]
DEBUG = false
DB_ENGINE = "django.db.backends.postgresql"
DB_NAME = "ragx"
DB_USER = "postgres"
DB_PASSWORD = "123456"
DB_HOST = "10.10.0.100"
DB_PORT = 5432

[development]
DEBUG = true
DB_ENGINE = "django.db.backends.sqlite3"
DB_NAME = "ragx.db"
DB_USER = ""
DB_PASSWORD = ""
DB_HOST = ""
DB_PORT = 0

[test]
DEBUG = true
DB_ENGINE = "django.db.backends.mysql"
DB_NAME = "ragx"
DB_USER = "root"
DB_PASSWORD = "123456"
DB_HOST = "127.0.0.1"
DB_PORT = 3306

your python code:

from toml_env import load_env

env = load_env(".env.toml")

# `os.environ.get()` also works, but it always return string

# you have better choice with the following methods：

project: str = env.get("PROJECT")
db_name: str = env.get_str("DB_NAME")
db_user: str = env.get_str("DB_USER", "root")
db_pass: str = env.get_str("DB_PASS", "password")
db_host: str = env.get_str("DB_HOST", "localhost")
db_port: int = env.get_int("DB_PORT", 3306)

debug: bool = env.get_bool("DEBUG", False)
sentry_dsn: str = env.get_str("SENTRY_DSN", None, nullable=True)

print(debug, db_name, db_user, db_pass, db_host, db_port, sentry_dsn)

run your python code:

$ export ENV=development
$ python your_code.py

Methods

load_env function

def load_env(path: str = ".env.toml", override: bool = False)

• path: the path to the .env.toml file;
• override:
  • if os.environ does not have the environment variables, it will load the environment variables from the .env.toml file;
  • if os.environ already has the environment variables, and override=True, it will override the environment variables with the values in the .env.toml file;
  • if os.environ already has the environment variables, and override=False, it will not override the environment variables with the values in the .env.toml file;

get method

• get(key: str, default=None, nullable=False) -> Any
• key: the key in the .env.toml file;
• default: the default value if the key is not found in the .env.toml file;
• nullable: if the key is not found in the .env.toml file, and the default value is None, you should set nullable=True, otherwise it will raise TomlEnvError exception;

get_str method

• get_str(key: str, default=None, nullable=False) -> str
• key: the key in the .env.toml file;
• default: the default value if the key is not found in the .env.toml file;
• nullable: if the key is not found in the .env.toml file, and the default value is None, you should set nullable=True, otherwise it will raise TomlEnvError exception;

get_int method

• get_int(key: str, default=None, nullable=False) -> int
• key: the key in the .env.toml file;
• default: the default value if the key is not found in the .env.toml file;
• nullable: if the key is not found in the .env.toml file, and the default value is None, you should set nullable=True, otherwise it will raise TomlEnvError exception;

get_float method

• get_float(key: str, default=None, nullable=False) -> float
• key: the key in the .env.toml file;
• default: the default value if the key is not found in the .env.toml file;
• nullable: if the key is not found in the .env.toml file, and the default value is None, you should set nullable=True, otherwise it will raise TomlEnvError exception;

get_bool method

• get_bool(key: str, default=None, nullable=False) -> bool
• key: the key in the .env.toml file;
• default: the default value if the key is not found in the .env.toml file;
• nullable: if the key is not found in the .env.toml file, and the default value is None, you should set nullable=True, otherwise it will raise TomlEnvError exception;
