""" This module converts code written for numarray to run with numpy Makes the following changes: * Changes import statements import numarray.package --> import numpy.numarray.package as numarray_package with all numarray.package in code changed to numarray_package import numarray --> import numpy.numarray as numarray import numarray.package as <yyy> --> import numpy.numarray.package as <yyy> from numarray import <xxx> --> from numpy.numarray import <xxx> from numarray.package import <xxx> --> from numpy.numarray.package import <xxx> package can be convolve, image, nd_image, mlab, linear_algebra, ma, matrix, fft, random_array * Makes search and replace changes to: - .imaginary --> .imag - .flat --> .ravel() (most of the time) - .byteswapped() --> .byteswap(False) - .byteswap() --> .byteswap(True) - .info() --> numarray.info(self) - .isaligned() --> .flags.aligned - .isbyteswapped() --> (not .dtype.isnative) - .typecode() --> .dtype.char - .iscontiguous() --> .flags.contiguous - .is_c_array() --> .flags.carray and .dtype.isnative - .is_fortran_contiguous() --> .flags.fortran - .is_f_array() --> .dtype.isnative and .flags.farray - .itemsize() --> .itemsize - .nelements() --> .size - self.new(type) --> numarray.newobj(self, type) - .repeat(r) --> .repeat(r, axis=0) - .size() --> .size - self.type() -- numarray.typefrom(self) - .typecode() --> .dtype.char - .stddev() --> .std() - .togglebyteorder() --> numarray.togglebyteorder(self) - .getshape() --> .shape - .setshape(obj) --> .shape=obj - .getflat() --> .ravel() - .getreal() --> .real - .setreal() --> .real = - .getimag() --> .imag - .setimag() --> .imag = - .getimaginary() --> .imag - .setimaginary() --> .imag """ __all__ = ['convertfile', 'convertall', 'converttree', 'convertsrc'] import sys import os import re import glob def changeimports(fstr, name, newname): importstr = 'import %s' % name importasstr = 'import %s as ' % name fromstr = 'from %s import ' % name fromall=0 name_ = name if ('.' in name): name_ = name.replace('.','_') fstr = re.sub(r'(import\s+[^,\n\r]+,\s*)(%s)' % name, "\\1%s as %s" % (newname, name), fstr) fstr = fstr.replace(importasstr, 'import %s as ' % newname) fstr = fstr.replace(importstr, 'import %s as %s' % (newname,name_)) if (name_ != name): fstr = fstr.replace(name, name_) ind = 0 Nlen = len(fromstr) Nlen2 = len("from %s import " % newname) while 1: found = fstr.find(fromstr,ind) if (found < 0): break ind = found + Nlen if fstr[ind] == '*': continue fstr = "%sfrom %s import %s" % (fstr[:found], newname, fstr[ind:]) ind += Nlen2 -
