opts, args This function works like getopt(), except that GNU style scanning mode is used by default. This means that option and non-option arguments may be intermixed. The getopt() function stops processing options as soon as a non-option argument is encountered. If the first character of the option string is `+', or if the environment variable POSIXLY_CORRECT is set, then option processing stops as soon as a non-option argument is encountered. t +i t POSIXLY_CORRECTi s --i R ( t isinstancet strR R t Truet ost environt gett FalseR R t append( R R R R t prog_argst all_options_first( ( s /usr/lib64/python2.7/getopt.pyR ^ s2 *$* c C s y | j d } Wn t k r, d } n X| | | | d } } t | | \ } } | r | d k r | s t d | | n | d | d } } q n" | d k r t d | | n | j d | | p d f | | f S( Nt =i s option --%s requires argumenti s% option --%s must not have an arguments --R ( t indext ValueErrort Nonet long_has_argsR R ( R R R R t it optargt has_arg( ( s /usr/lib64/python2.7/getopt.pyR s c C s g | D] } | j | r | ^ q } | sD t d | | n | | k rZ t | f S| d | k rt t | f St | d k r t d | | n | d } | j d } | r | d } n | | f S( Ns option --%s not recognizedR# i s option --%s not a unique prefixi i( R R R R t lent endswith( R R t ot possibilitiest unique_matchR* ( ( s /usr/lib64/python2.7/getopt.pyR' s ( c C s x | d k r | d | d } } t | | r | d k rs | s[ t d | | n | d | d } } n | d } } n d } | j d | | f q W| | f S( NR i i s option -%s requires argumentR ( t short_has_argR R ( R t optstringR R R R) ( ( s /usr/lib64/python2.7/getopt.pyR s c C sh xN t t | D]: } | | | k o4 d k n r | j d | d Sq Wt d | | d S( Nt :i s option -%s not recognized( t rangeR+ R R ( R R R( ( ( s /usr/lib64/python2.7/getopt.pyR0 s t __main__i s a:bs alpha=t beta( t __doc__t __all__R R R R R R R R' R R0 R t syst argv( ( ( s /usr/lib64/python2.7/getopt.pyt s + 2
