formate.classes

Core classes.

Classes:

FormateConfigDict	typing.TypedDict representing the configuration mapping parsed from formate.toml or similar.
ExpandedHookDict	typing.TypedDict representing the expanded form of a hook in the mapping parsed from the config file.
EntryPoint(name, obj)	Represents an entry point for a hook.
Hook(name[, priority, args, kwargs, …])	Represents a formate reformatting hook.

Data:

HooksMapping

Type hint for the hooks key of the formate configuration mapping.

typeddict FormateConfigDict

Bases: TypedDict

typing.TypedDict representing the configuration mapping parsed from formate.toml or similar.

Optional Keys

• hooks (Mapping[str, Union[int, ExpandedHookDict]]) – Mapping defining the hooks to run. Each value can either be an integer (the priority) or a ExpandedHookDict.

• config (Mapping[str, Any]) – Mapping defining the global configuration for formate.

typeddict ExpandedHookDict

Bases: TypedDict

typing.TypedDict representing the expanded form of a hook in the mapping parsed from the config file.

Required Keys

• priority (int) – The priority of the hook.

Optional Keys

• args (List[Any]) – The positional arguments passed to the hook function.

• kwargs (Dict[str, Any]) – The keyword arguments passed to the hook function.

HooksMapping

Type hint for the hooks key of the formate configuration mapping.

Alias of Mapping[str, Union[int, ExpandedHookDict]]

class EntryPoint(name, obj)

Bases: object

Methods:

__getstate__()	Used for pickling.
__repr__()	Return a string representation of the EntryPoint.
__setattr__(name, val)	Implement setattr(self, name).
__setstate__(state)	Used for pickling.
from_dict(d)	Construct an instance of EntryPoint from a dictionary.
to_dict([convert_values])	Returns a dictionary containing the contents of the EntryPoint object.

name	The name of the hook.
priority	The priority of the hook.
args	The positional arguments passed to the hook function.
kwargs	The keyword arguments passed to the hook function.
entry_point
global_config	A read-only view on the global configuration mapping, for hooks to do with as they wish.
