endlineno instance-attribute
¤
The ending line number of the object.
exports instance-attribute
¤
The names of the objects exported by this (module) object through the __all__
variable.
Exports can contain string (object names) or resolvable names, like other lists of exports coming from submodules:
from .submodule import __all__ as submodule_all
__all__ = ["hello", *submodule_all]
Exports get expanded by the loader before it expands wildcards and resolves aliases.
extra instance-attribute
¤
Namespaced dictionaries storing extra metadata for this object, used by extensions.
filepath property
¤
The file path (or directory list for namespace packages) where this object was defined.
Examples:
>>> import griffe

>>> markdown.filepath
PosixPath('~/project/.venv/lib/python3.11/site-packages/markdown/__init__.py')
functions property
¤
The function members.
This method is part of the consumer API: do not use when producing Griffe trees!
has_docstrings property
¤
has_docstrings: bool
Whether this object or any of its members has a docstring (empty or not).
Inherited members are not considered. Imported members are not considered, unless they are also public.
imports instance-attribute
¤
The other objects imported by this object.
Keys are the names within the object (from ... import ... as AS_NAME
), while the values are the actual names of the objects (from ... import REAL_NAME as ...
).
inherited class-attribute
instance-attribute
¤
inherited: bool = False
Always false for objects.
Only aliases can be marked as inherited.
inherited_members cached
property
¤
Members that are inherited from base classes.
This method is part of the consumer API: do not use when producing Griffe trees!
is_class_private property
¤
is_class_private: bool
Whether this object/alias is class-private (starts with __
and is a class member).
is_collection class-attribute
instance-attribute
¤
is_collection: bool = False
Always false for objects.
is_imported property
¤
is_imported: bool

¤
is_namespace_package: bool
Whether this object is a namespace package (top folder, no __init__.py
).
is_namespace_subpackage property
¤
is_namespace_subpackage: bool
Whether this object is a namespace subpackage.
is_private property
¤
is_private: bool
Whether this object/alias is private (starts with _
) but not special.
is_public property
¤
is_public: bool
Whether this object is considered public.
In modules, developers can mark objects as public thanks to the __all__
variable. In classes however, there is no convention or standard to do so.
Therefore, to decide whether an object is public, we follow this algorithm:
- If the object's
public
attribute is set (boolean), return its value. - If the object is listed in its parent's (a module)
__all__
attribute, it is public. - If the parent (module) defines
__all__
and the object is not listed in, it is private. - If the object has a private name, it is private.
- If the object was imported from another module, it is private.
- Otherwise, the object is public.
is_special property
¤
is_special: bool
Whether this object/alias is special ("dunder" attribute/method, starts and end with __
).
is_wildcard_exposed property
¤
is_wildcard_exposed: bool
Whether this object/alias is exposed to wildcard imports.
To be exposed to wildcard imports, an object/alias must:
- be available at runtime
- have a module as parent
- be listed in
__all__
if__all__
is defined - or not be private (having a name starting with an underscore)
Special case for Griffe trees: a submodule is only exposed if its parent imports it.
Returns:
-
bool
–True or False.

The lines collection attached to this object or its parents.
Raises:
-
ValueError
–When no modules collection can be found in the object or its parents.

>>> # The `module` of a module is itself.
>>> markdown["core"].module
Module(PosixPath('~/project/.venv/lib/python3.11/site-packages/markdown/core.py'))
Raises:
-
ValueError

'markdown.core.Markdown.references'
relative_filepath property
¤
relative_filepath: Path
