Each field in core metadata maps to a key of this dictionary (when data is provided). The key is lower-case and underscores are used instead of dashes compared to the equivalent core metadata field. Any core metadata field that can be specified multiple times or can hold multiple values in a single field have a key with a plural name. See :class:`Metadata` whose attributes match the keys of this dictionary. Core metadata fields that can be specified multiple times are stored as a list or dict depending on which is appropriate for the field. Any fields which hold multiple values in a single field are stored as a list. r �metadata_version�namer � list[str]� platforms�summary� description�keywords� home_page�author� author_email�license�supported_platforms� download_url� classifiers�requires�provides� obsoletes� maintainer�maintainer_email� requires_dist� provides_dist�obsoletes_dist�requires_python�requires_external�dict[str, str]� project_urls�description_content_type�provides_extra�dynamic�license_expression� license_filesN)r! r# r$ r% r& r r r r r, @ s> r, F)�total> r. rG r9 r7 r2 r> r? rJ r1 r- rC r r6 r4 r5 > r: r8 rH r0 rI rB rA r= r; rD r@ r< rK rF r r/ )�datar c C s dd� | � d�D �S )zCSplit a string of comma-separated keywords into a list of keywords.c S s g | ] }|� � �qS r ��strip)�.0�kr r r � <listcomp>� � z#_parse_keywords.<locals>.<listcomp>�,)�split)rM r r r �_parse_keywords� s rV rE c C sf i }| D ]X}dd� |� dd�D �}|�dgtddt|� � � |\}}||v rXtd��|||< q|S ) z?Parse a list of label/URL string pairings separated by a comma.c S s g | ] }|� � �qS r rN )rP �pr r r rR � rS z'_parse_project_urls.<locals>.<listcomp>rT r � r � z duplicate labels in project urls)rU �extend�max�len�KeyError)rM �urls�pair�parts�label�urlr r r �_parse_project_urls� s rc zemail.message.Message� bytes | str)�msg�sourcer c C s� t |t�r$| �� }t |t�s J �|S | jdd�}t |t�s>J �z|�dd�W S tyz } ztd�|�W Y d}~n d}~0 0 dS )z Get the body of the message.T��decode�utf8�strictz payload in an invalid encodingN)� isinstancer � get_payload�bytesrh �UnicodeDecodeError� ValueError)re rf �payload�bpayload�excr r r � _get_payload� s rs r5 r6 r: r2 rG r9 rI r4 r3 r7 rJ rK r> r? r- r. r= rB r0 r< rA rH r; r@ rD rC r1 r8 r ) r5 z author-email� classifierr2 zdescription-content-typez download-urlrI z home-pager3 r7 zlicense-expressionz license-filer> zmaintainer-email�metadata-versionr. r= zobsoletes-dist�platformz project-urlr< z provides-distzprovides-extrar; z requires-distzrequires-externalzrequires-pythonr1 zsupported-platformr c C s i | ]\}}||�qS r r )rP �email�rawr r r � <dictcomp> rS ry z(tuple[RawMetadata, dict[str, list[str]]]c C s� i }i }t | t�r,tjjtjjd��| �}ntjjtjjd�� | �}t |� � �D �]�}|� � }|� |�pjg }g }d}|D ]�}t |tjjtf�s�J �t |tjj��rg } tj�|�D ]F\} } z| �dd� W n ty� d} d}Y n0 d} | �| | f� q�|�ttj�| ��� qx|�|� qx|�s.|||< qPt�|�} | du �rL|||< qP| tv �rrt|�dk�rr|d || < qP| tv �r�||| < qP| d k�r�t|�dk�r�t|d �|| < qP| d k�r�zt|�|| < W n t �y� |||< Y n0 qP|||< qPzt || �} W n4 t �y6 |� d g ��|j t | t!�d �� Y n\0 | �r�d |v �rpt"t|�#d ��}|� d g ��$|| g� n"d |v �r�|d �| � n| |d < t"t%|�|fS )a Parse a distribution's metadata stored as email headers (e.g. from ``METADATA``). This function returns a two-item tuple of dicts. The first dict is of recognized fields from the core metadata specification. Fields that can be parsed and translated into Python's built-in types are converted appropriately. All other fields are left as-is. Fields that are allowed to appear multiple times are stored as lists. The second dict contains all other fields from the metadata. This includes any unrecognized fields. It also includes any fields which are expected to be parsed into a built-in type but were not formatted appropriately. Finally, any fields that are expected to appear only once but are repeated are included in this dict. )�policyTri rj �latin1FNr r r3 rF r2 rg )&rk r rw �parser�Parserrz �compat32�parsestr� BytesParser� parsebytes� frozenset�keys�lower�get_all�header�Header� decode_headerrh rn �append� make_header�_EMAIL_TO_RAW_MAPPING�get�_STRING_FIELDSr\ � _LIST_FIELDSrV rc r] rs ro � setdefaultrl rm r �poprZ r, )rM rx �unparsed�parsedr. �headers�valueZvalid_encoding�h�chunks�bin�encoding�raw_namerp Zdescription_headerr r r � parse_email sv � � r� )�1.0�1.1�1.2�2.1�2.2z2.3�2.4)r- r. r c @ s( e Zd ZU dZded< ded< ded< dd�dd d �d d �Zd dd d�dd�Zd ddd�dd�Zd9dddd�dd�Zddd �d d �Z ddd �d d �Z dd!d �d"d#�Z ddd �d$d%�Z ddd �d&d'�Z d(d(d �d)d*�Zd(d+d �d,d-�Zdd.d �d/d0�Zd(d1d �d2d3�Zdd4d �d5d6�Zd(d(d �d7d8�ZdS ):� _Validatorav Validate a metadata field.
