def __init__(name: str,
             supports_secrets: bool,

Creates config provider from a toml file

The provider loads the toml file with specified name and from specified folder. If global_dir is specified, it will additionally look for file_name in dlt global dir (home dir by default) and merge the content. The "settings" (settings_dir) values overwrite the "global" values.

If none of the files exist, an empty provider is created.

Arguments:

• name(str) - name of the provider when registering in context
• supports_secrets(bool) - allows to store secret values in this provider
• file_name str - The name of toml file to load
• settings_dir str, optional - The location of file_name. If not specified, defaults to $cwd/.dlt
• global_dir bool, optional - Looks for file_name in global_dir (defaults to dlt home directory which in most cases is $HOME/.dlt)

Raises:

• TomlProviderReadException - File could not be read, most probably toml parsing error
