For the purposes of this module, the following nomenclature is used: - "src-layout": a directory representing a Python project that contains a "src" folder. Everything under the "src" folder is meant to be included in the distribution when packaging the project. Example:: . ├── tox.ini ├── pyproject.toml └── src/ └── mypkg/ ├── __init__.py ├── mymodule.py └── my_data_file.txt - "flat-layout": a Python project that does not use "src-layout" but instead have a directory under the project root for each package:: . ├── tox.ini ├── pyproject.toml └── mypkg/ ├── __init__.py ├── mymodule.py └── my_data_file.txt - "single-module": a project that contains a single Python script direct under the project root (no directory used):: . ├── tox.ini ├── pyproject.toml └── mymodule.py � N)� fnmatchcase)�glob)�Path) � TYPE_CHECKING�Dict�Iterable�Iterator�List�Mapping�Optional�Tuple�Union)�log)� convert_path)� Distribution)�path�returnc C s t j�| ��� S )N)�osr �basename� isidentifier)r � r �</tmp/pip-install-251nq386/setuptools/setuptools/discovery.py� _valid_nameG s r c @ s> e Zd ZdZed�dd�Zeed�dd�Zeed�dd �Zd S ) �_Filterz� Given a list of patterns, create a callable that will be true only if the input matches at least one of the patterns. )�patternsc G s t �|�| _d S )N)�dict�fromkeys� _patterns)�selfr r r r �__init__R s z_Filter.__init__)�itemr c s t � fdd�| jD ��S )Nc 3 s | ]}t � |�V qd S )N)r )�.0�pat)r r r � <genexpr>V s z#_Filter.__call__.<locals>.<genexpr>)�anyr )r r r )r r �__call__U s z_Filter.__call__c C s || j kS )N)r )r r r r r � __contains__X s z_Filter.__contains__N) �__name__� __module__� __qualname__�__doc__�strr �boolr% r& r r r r r L s r c @ sx e Zd ZU dZdZeedf ed< dZeedf ed< e de e e e e e e d�d d ��Z e e eeed�d d ��Zd S )�_Finderz@Base class that exposes functionality for module/package findersr .�ALWAYS_EXCLUDE�DEFAULT_EXCLUDE�.��*)�where�exclude�includer c C s2 |p| j }t| �tt|��t| j|�� t|� ��S )aF Return a list of all Python items (packages or modules, depending on the finder implementation) found within directory 'where'. 'where' is the root directory which will be searched. It should be supplied as a "cross-platform" (i.e. URL-style) path; it will be converted to the appropriate local path syntax. 'exclude' is a sequence of names to exclude; '*' can be used as a wildcard in the names. When finding packages, 'foo.*' will exclude all subpackages of 'foo' (but not 'foo' itself). 'include' is a sequence of names to include. If it's specified, only the named items will be included. If it's not specified, all found items will be included. 'include' can contain shell style wildcard patterns just like 'exclude'. )r/ �list� _find_iterr r+ r r. )�clsr3 r4 r5 r r r �findb s z _Finder.findc C s t �d S )N)�NotImplementedError)r8 r3 r4 r5 r r r r7 � s z_Finder._find_iterN)r0 r r1 )r' r( r) r* r. r r+ �__annotations__r/ � classmethod�_Pathr r r9 r �StrIterr7 r r r r r- \ s r- c @ sB e Zd ZdZdZeeeeed�dd��Z e ee e d�dd��Z d S ) � PackageFinderzI Generate a list of all Python packages found within a directory )Zez_setupz *__pycache__)r3 r4 r5 r c c s� x�t jt|�dd�D ]�\}}}|dd� }g |dd�< x�|D ]�}t j�||�} t j�| |�} | �t jjd�} d|ks<| �| | �s�q<|| �r�|| �s�| V | � d�|ks<| � d�|kr�q<|� |� q<W qW dS )zy All the packages found in 'where' that pass the 'include' filter, but not the 'exclude' filter.

Normally auto-discovery would not be triggered if ``ext_modules`` are set (this is done for backward compatibility with existing packages relying on ``setup.py`` or ``setup.cfg``). However, ``setuptools`` can call this function to ignore given ``ext_modules`` and proceed with the auto-discovery if ``packages`` and ``py_modules`` are not given (e.g. when using pyproject.toml metadata).

The "src-layout" is relatively safe for automatic discovery. We assume that everything within is meant to be included in the distribution.

Since the ``flat-layout`` is more dangerous in terms of accidentally including extra files/directories, this function is more conservative and will raise an error if multiple packages or modules are found.

To avoid accidental inclusion of unwanted files or directories, setuptools will not proceed with this build. If you are trying to create a single distribution with multiple a� on purpose, you should not rely on automatic discovery. Instead, consider the following options: 1. set up custom discovery (`find` directive with `include` or `exclude`) 2. use a `src-layout` 3. explicitly set `py_modules` or `packages` with a list of names To find more information, look for "package discovery" on setuptools docs. )�len�inspectr� Zsetuptools.errorsr� )r r� r� r� r� �msgr r r r� � s z/ConfigDiscovery._ensure_no_accidental_inclusionc C sB | j jjs| j jrdS t�d� | �� p.| �� }|r>|| j j_dS )z�The packages/modules are the essential contribution of the author.
