banana package

banana.register(path)

Register configurations.

This function is provided for its simple heuristics for configuration file detection. The idea behind is that it can be invoked by runner scripts in the following way:

import banana
banana.register(__file__)

Thus, if it’s pointing to a file with a name different from the conventional one (see cfg.name), it is assumed that this file is in the same folder of the configuration file, that is named with the conventional name.

Parameters:

path (str or os.PathLike) – a path pointing to configuration file, its parent directory, or another file in the same directory

Submodules

banana.cfg module

Configurations related objects.

This module contains the functions used to manage configurations. Moreover, the actual loaded configurations are stored in the module variable cfg, that is used as the source of truth for them.

banana.cfg.cfg = None

Global store for configurations

banana.cfg.detect(path=None)

Search configurations file.

It searches the configuration file in the following places, sorted:

• provided path (e.g. CLI argument)

• current directory

• home directory

• user default configurations directory

• system default configurations directory

If the path resolved is a directory (all cases but file path provided), it is assumed that the file name is that stored in the module level variable name.

Parameters:

path (str ot os.PathLike) – path to a configuration file, or to a folder containing it

Returns:

the resolved path

Return type:

os.PathLike

Raises:

FileNotFoundError – if the configuration file is not foundd in any of the places above

banana.cfg.load(path)

Load configurations.

Load everything as a dictionary. Determines root from the loaded dictionary:

• if the key root is found in the configuration file, it is treated as an absolute path, or a relative one (relative to the configuration file parent folder)

• otherwise root is assigned to the configuration file parent folder itself

For the section “path”, all paths are converted to pathlib.Path type, and (if not absolute) they are considered to be relative to root.

No other conversion is performed.

Parameters:

path (str or os.PathLike) – configurations file path

Returns:

loaded configurations

Return type:

dict

banana.cfg.name = 'banana.yaml'

Configurations file conventional name
