Codec modules must have names corresponding to normalized encoding names as defined in the normalize_encoding() function below, e.g. 'utf-8' must be implemented by the module 'utf_8.py'. Each codec module must export the following interface: * getregentry() -> codecs.CodecInfo object The getregentry() API must return a CodecInfo object with encoder, decoder, incrementalencoder, incrementaldecoder, streamwriter and streamreader atttributes which adhere to the Python Codec Interface Standard. In addition, a module may optionally also define the following APIs which are then used by the package's codec search function: * getaliases() -> sequence of encoding name strings to use as aliases Alias names returned by getaliases() must be normalized encoding names as defined by normalize_encoding().

Normalization works as follows: all non-alphanumeric characters except the dot used for Python package names are collapsed and replaced with a single underscore, e.g. ' -;#' becomes '_'. Leading and trailing underscores are removed. Note that encoding names should be ASCII only; if they do use non-ASCII characters, these must be Latin-1 compatible. �asciiF�.�_T� )� isinstance�bytes�str�isalnum�append�join)�encoding�chars�punct�cr r r �normalize_encoding* s r c C s/ t j | t � } | t k r" | St | � } t j | � pU t j | j d d � � } | d k rs | | g } n | g } xc | D]U } | s� d | k r� q� n y t d | d t d d �} Wn t k r� Yq� XPq� Wd } y | j } Wn t k r d } Yn X| d k r$d t | <d S| � } t | t j � s�d t | � k o\d k n s�t d | j | j f � � n t | d � sJt | d � sJ| d d k r�t | d � sJ| d d k r�t | d � sJt | � d k r| d d k rt | d � sJt | � d k ri| d d k rit | d � rit d | j | j f � � n t | � d k s�| d d k r�| d d t | � | j j d d � d f 7} n t j | � } n | t | <y | j � } Wn t k r Yn+ Xx' | D] } | t k r| t | <qqW| S)Nr r z encodings.�fromlist�levelr � � z#module "%s" (%s) failed to registerr � � � z'incompatible codecs in module "%s" (%s)� )N)�_cache�get�_unknownr �_aliases�replace� __import__� _import_tail� ImportError� getregentry�AttributeErrorr �codecs� CodecInfo�lenr r �__file__�callable�split� getaliases) r �entry� norm_encoding�aliased_encoding�modnames�modname�modr* � codecaliases�aliasr r r �search_functionE sf ""!!33"5 r; )�__doc__r, r r r" r$ r( r% � LookupError� SystemErrorr r r; �registerr r r r �<module> s S
