If you have a version string that isn't rational (i.e. NormalizedVersion doesn't like it) then you might be able to get an equivalent (or close) rational version from this function. This does a number of simple normalizations to the given string, based on observation of versions currently in use on PyPI. Given a dump of those version during PyCon 2009, 4287 of them: - 2312 (53.93%) match NormalizedVersion without change with the automatic suggestion - 3474 (81.04%) match when using this suggestion method @param s {str} An irrational version string. @returns A rational version string, or None, if couldn't determine one. �-alphar` �-betart r� r� ru r4 �-finalr� �-pre�-release�.release�-stabler� rX rb � �.finalrc zpre$Zpre0zdev$Zdev0z([abc]|rc)[\-\.](\d+)$z\1\2z[\-\.](dev)[\-\.]?r?(\d+)$z.\1\2z[.~]?([abc])\.?z\1r3 r Nz\b0+(\d+)(?!\d)z (\d+[abc])$z\g<1>0z\.?(dev-r|dev\.r)\.?(\d+)$z.dev\2z-(a|b|c)(\d+)$z[\.\-](dev|devel)$z.dev0z(?![\.\-])dev$z(final|stable)$z\.?(r|-|-r)\.?(\d+)$z.post\2z\.?(dev|git|bzr)\.?(\d+)$z\.?(pre|preview|-c)(\d+)$zc\g<2>zp(\d+)$z.post\1�r� r` �r� rt �r� r` �r� rt �ru r4 �r� r� �r� r4 �r� r� �r� r� �r� r� �r� rX �rb rX �r� r� �r� r� �rc r� )r� r� r� r� r� r� r� r� r� r� r� r� r� r� r� )rr r r@ �replace�rer� r{ )r �rs�origr� r r r �_suggest_normalized_version� sH r� z([a-z]+|\d+|[\.-])r4 zfinal-�@)rl �previewr� ru rn r� rX c C s~ dd� }g }xh|| �D ]\}|j d�rh|dk rJx |rH|d dkrH|j� q.W x |rf|d dkrf|j� qLW |j|� qW t|�S ) Nc S sx g }xdt j| j� �D ]R}tj||�}|rd|d d� koBdkn rT|jd�}nd| }|j|� qW |jd� |S )N�0r �9� �*z*final)� _VERSION_PARTrg r@ �_VERSION_REPLACErI �zfillrD )r rS r5 r r r � get_partsC s z _legacy_key.<locals>.get_partsr� z*finalr z*final-�00000000rd rd )r{ �poprD r )r r� rS r5 r r r � _legacy_keyB s r� c @ s e Zd Zdd� Zedd� �ZdS )r c C s t |�S )N)r� )r r r r r r ] s zLegacyVersion.parsec C s: d}x0| j D ]&}t|t�r |jd�r |dk r d}P q W |S )NFr� z*finalT)r r r r{ )r rS r| r r r r0 ` s zLegacyVersion.is_prereleaseN)r r r r r1 r0 r r r r r \ s c @ s4 e Zd ZeZeej�Zded< ej d�Z dd� Z dS )r r� z~=z^(\d+(\.\d+)*)c C s` ||k r dS | j jt|��}|s2tjd||� dS |j� d }d|krV|jdd�d }t||�S )NFzACannot compute compatible match for version %s and constraint %sTr rX r )� numeric_rerP rz �logger�warningrf �rsplitr )r rK rM rG ri r r r r r� s s z LegacyMatcher._match_compatibleN) r r r r r= �dictr2 rH r� �compiler� r� r r r r r k s zN^(\d+)\.(\d+)\.(\d+)(-[a-z0-9]+(\.[a-z0-9-]+)*)?(\+[a-z0-9]+(\.[a-z0-9-]+)*)?$c C s t j| �S )N)� _SEMVER_RErP )r r r r r� � s r� c C sn dd� }t | �}|s t| ��|j� }dd� |d d� D �\}}}||d d�||d d� }}|||f||fS ) Nc S s8 | d kr|f}n$| dd � j d�}tdd� |D ��}|S )Nr rX c S s" g | ]}|j � r|jd �n|�qS )r� )rh r� )rV r5 r r r r� � s z5_semantic_key.<locals>.make_tuple.<locals>.<listcomp>)rg r )r ZabsentrS r r r r � make_tuple� s z!_semantic_key.<locals>.make_tuplec S s g | ] }t |��qS r )rU )rV r� r r r r� � s z!_semantic_key.<locals>.<listcomp>r� �|� r� )r� r rf ) r r� ri rf �major�minor�patchrl �buildr r r � _semantic_key� s r� c @ s e Zd Zdd� Zedd� �ZdS )r c C s t |�S )N)r� )r r r r r r � s zSemanticVersion.parsec C s | j d d dkS )Nr r r� )r )r r r r r0 � s z SemanticVersion.is_prereleaseN)r r r r r1 r0 r r r r r � s c @ s e Zd ZeZdS )r N)r r r r r= r r r r r � s c @ s6 e Zd Zd dd�Zdd� Zdd� Zdd � Zd d � ZdS ) � VersionSchemeNc C s || _ || _|| _d S )N)rA �matcher� suggester)r rA r� r� r r r r � s zVersionScheme.__init__c C s2 y| j j|� d}W n tk r, d}Y nX |S )NTF)r� r= r )r r rS r r r �is_valid_version� s z VersionScheme.is_valid_versionc C s0 y| j |� d}W n tk r* d}Y nX |S )NTF)r� r )r r rS r r r �is_valid_matcher� s z VersionScheme.is_valid_matcherc C s | j d| �S )z: Used for processing some metadata fields zdummy_name (%s))r� )r r r r r �is_valid_constraint_list� s z&VersionScheme.is_valid_constraint_listc C s | j d krd }n | j |�}|S )N)r� )r r rS r r r �suggest� s zVersionScheme.suggest)N)r r r r r� r� r� r� r r r r r� � s r� c C s |S )Nr )r r r r r r6 � s r6 )� normalized�legacyZsemanticr� �defaultc C s | t krtd| ��t | S )Nzunknown scheme name: %r)�_SCHEMESr> )r? r r r r � s )*r �loggingr� �compatr �utilr �__all__� getLoggerr r� r> r �objectr r2 r� re rq rr r r r r� r� r� r� r� �Ir� r� r� r r r� r� r� r r r� r� r r r r r �<module> s| 1d =$ W .r $
