U me@s0dZddlZddlZddlmZefddZdS)ac 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).

An IOError will be raised if the resource cannot 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. __file__Nz%r has no __file__! __loader__zutf-8rb)sysmodulesgetattrOSErrorospathjoindirnameget_dataAttributeErrorrdecodeopennormpath) identifierpkgnamemodfnr loaderdatar;/tmp/pip-unpacked-wheel-rdz2gdd2/sympy/utilities/pkgdata.py get_resources   r)__doc__rr ior__name__rrrrrs
