get_var_list(name, default=Ellipsis, cast=<class 'str'>, sep=';')

Retrieve a list of values from an environment variable, and raise if it’s undefined and no default was passed.

Parameters:

  • name (str) – The name of the environment variable.

  • default (list[TypeVar(T)] | Any) – The default value to return if the environment variable is not defined. If nothing is passed, undefined variables raise an exception.

  • cast (Callable[[str], TypeVar(T)]) – A function to cast values to a specific type. Default is str.

  • sep (str | None) – The seperator to use between values. Default is ;. Pass None to avoid splitting.

Raises:

RuntimeError – If the environment variable is not defined and no default was provided.

Return type:

list[TypeVar(T)]

Returns:

The value of the environment variable cast to type by the specified function.
