ó Ąź™\c@ sTdZddlmZmZddlZddlZddlmZe d„Z dS(sc pkgdata is a simple, extensible way for a package to acquire data file resources. The getResource function is equivalent to the standard idioms, such as the following minimal implementation:: import sys, os def getResource(identifier, pkgname=__name__): pkgpath = os.path.dirname(sys.modules[pkgname].__file__) path = os.path.join(pkgpath, identifier) return open(os.path.normpath(path), mode='rb') When a __loader__ is present on the module given by __name__, it will defer getResource to its get_data implementation and return it as a file-like object (such as StringIO). i˙˙˙˙(tprint_functiontdivisionN(t cStringIOcC sŐtj|}t|ddƒ}|dkr:tdƒ‚ntjjtjj|ƒ|ƒ}t|ddƒ}|dk rźy|j |ƒ}Wntt fk rĽqźXt |j dƒƒSnt tjj|ƒdƒS(s? Acquire a readable object for a given package name and identifier. An IOError will be raised if the resource can not be found. For example:: mydata = get_resource('mypkgdata.jpg').read() Note that the package name must be fully qualified, if given, such that it would be found in sys.modules. In some cases, getResource will return a real file object. In that case, it may be useful to use its name attribute to get the path rather than use it as a file-like object. For example, you may be handing data off to a C API. t__file__s%r has no __file__!t __loader__sutf-8trbN(tsystmodulestgetattrtNonetIOErrortostpathtjointdirnametget_datatAttributeErrortStringIOtdecodetopentnormpath(t identifiertpkgnametmodtfnR tloadertdata((s6lib/python2.7/site-packages/sympy/utilities/pkgdata.pyt get_resources  !
