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. �-alphari �-betarw r� r� rx r3 �-finalr8 �-pre�-release�.release�-stabler� ra rk � �.finalrl zpre$�pre0zdev$�dev0z([abc]|rc)[\-\.](\d+)$z\1\2z[\-\.](dev)[\-\.]?r?(\d+)$z.\1\2z[.~]?([abc])\.?z\1r2 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� ri �r� rw �zalphari �zbetarw �zrcr3 �r� r8 �r� r3 �r� r8 �r� r8 �r� r8 �r� ra �rk ra �r� r8 �r� r8 �zfinalr8 )r� r� r� r� r� r� r� r� r� r� r� r� r� r� r� )ru r rF �replacer] r� r~ )r �rs�origr� r r r �_suggest_normalized_version� sH r� z([a-z]+|\d+|[\.-])r3 rp �previewzfinal-r� rx �@rr c C s� d d � } g } x� | | � D]� } | j d � r� | d k rj x' | rf | d d k rf | j � qC Wn x' | r� | d d k r� | j � qm Wn | j | � q Wt | � S) Nc S s� g } x� t j | j � � D]p } t j | | � } | r d | d d � k o[ d k n rr | j d � } n d | } | j | � q q W| j d � | S)N�0r �9re �*z*final)� _VERSION_PARTrH rF �_VERSION_REPLACErT �zfillrL )r r[ r4 r r r � get_parts4 s & z _legacy_key.<locals>.get_partsr� z*finalr z*final-�00000000rm rm )r~ �poprL r )r r� r[ r4 r r r � _legacy_key3 s r� c @ s. e Z d Z d d � Z e d d � � Z d S)r c C s t | � S)N)r� )r r r r r r N s zLegacyVersion.parsec C sR d } xE | j D]: } t | t � r | j d � r | d k r d } Pq q W| S)NFr� z*finalT)r r r r~ )r r[ r r r r r/ Q s zLegacyVersion.is_prereleaseN)r r r r r0 r/ r r r r r M s c @ sJ e Z d Z e Z e e j � Z d e d <e j d � Z d d � Z d S)r r� z~=z^(\d+(\.\d+)*)c C s� | | k r d S| j j t | � � } | sE t j d | | � d S| j � d } d | k rz | j d d � d } n t | | � S)NFzACannot compute compatible match for version %s and constraint %sTr ra r )� numeric_rerC r} �logger�warningrD �rsplitr� )r rV rX rR rM r r r r r� d s z LegacyMatcher._match_compatibleN) r r r r r@ �dictr1 rS r] r^ r� r� r r r r r \ s zN^(\d+)\.(\d+)\.(\d+)(-[a-z0-9]+(\.[a-z0-9-]+)*)?(\+[a-z0-9]+(\.[a-z0-9-]+)*)?$c C s t j | � S)N)� _SEMVER_RErC )r r r r r� z s r� c C s� d d � } t | � } | s- t | � � n | j � } d d � | d d � D� \ } } } | | d d � | | d d � } } | | | f | | f S) Nc S sN | d k r | f } n2 | d d � j d � } t d d � | D� � } | S)Nr ra c S s1 g | ]' } | j � r' | j d � n | � q S)re )�isdigitr� )r: r4 r r r r; � s z5_semantic_key.<locals>.make_tuple.<locals>.<listcomp>)rH r )r �absentr[ r r r r � make_tuple s z!_semantic_key.<locals>.make_tuplec S s g | ] } t | � � q Sr )r_ )r: r� r r r r; � s z!_semantic_key.<locals>.<listcomp>rb �|rc r� )r� r rD ) r r� rM rD �major�minor�patchrp �buildr r r � _semantic_key~ s &'r� c @ s. e Z d Z d d � Z e d d � � Z d S)r c C s t | � S)N)r� )r r r r r r � s zSemanticVersion.parsec C s | j d d d k S)Nr r r� )r )r r r r r/ � s z SemanticVersion.is_prereleaseN)r r r r r0 r/ r r r r r � s c @ s e Z d Z e Z d S)r N)r r r r r@ r r r r r � s c @ sO e Z d Z d d d � Z d d � Z d d � Z d d � Z d d � Z d S) � VersionSchemeNc C s | | _ | | _ | | _ d S)N)rG �matcher� suggester)r rG r� r� r r r r � s zVersionScheme.__init__c C s9 y | j j | � d } Wn t k r4 d } Yn X| S)NTF)r� r@ r )r r r[ r r r �is_valid_version� s z VersionScheme.is_valid_versionc C s6 y | j | � d } Wn t k r1 d } Yn X| S)NTF)r� r )r r r[ r r r �is_valid_matcher� s z VersionScheme.is_valid_matcherc C s | j d | � S)z: Used for processing some metadata fields zdummy_name (%s))r� )r r r r r �is_valid_constraint_list� s z&VersionScheme.is_valid_constraint_listc C s+ | j d k r d } n | j | � } | S)N)r� )r r r[ r r r �suggest� s zVersionScheme.suggest)r r r r r� r� r� r� r r r r r� � s r� � normalizedc C s | S)Nr )r r r r r r5 � s r5 �legacy�semantic�defaultc C s' | t k r t d | � � n t | S)Nzunknown scheme name: %r)�_SCHEMESrA )rE r r r r � s )(r �loggingr] �compatr �__all__� getLoggerr r� rA r �objectr r1 r^ rn rt ru r r� r r� r� r� r� r� �Ir� r� r� r r r� r� r� r r r� r� r r r r r �<module> s~ 1j /$ Q . r #
