Windows binary installers often have dependencies on other binary libraries which one would like to include in the filename for the installer such as PyOpenGL-2.0.1-Numpy23.exe
Subclass bdist_wininst to introduce a customisation point for acquiring the filename.
import sys, os, string, struct from distutils.command.bdist_wininst import bdist_wininst class BdistWinInstaller(bdist_wininst): """Version of bdist_wininst with customization point for filename This class should operate identically to the built-in class, it exists solely to provide the customization point. """ def get_installer_filename(self, directory, fullname, target_version= None): """Calculate the final installer filename""" if target_version: return os.path.join( directory, "%s.win32-py%s.exe" % ( fullname, target_version ) ) else: return os.path.join( directory, "%s.win32.exe" % fullname ) def create_exe (self, arcname, fullname, bitmap=None): """Do the actual creation of the executable file The base command, unfortunately, does not break down this command into sub-commands, so this method is almost entirely a duplication of the base-class method, with the only noticeable difference being the call to get_installer_filename(...) instead of calculating the filename inline. """ import struct self.mkpath(self.dist_dir) cfgdata = self.get_inidata() installer_name = self.get_installer_filename( self.dist_dir, fullname, self.target_version, ) self.announce("creating %s" % installer_name) if bitmap: bitmapdata = open(bitmap, "rb").read() bitmaplen = len(bitmapdata) else: bitmaplen = 0 file = open(installer_name, "wb") file.write(self.get_exe_bytes()) if bitmap: file.write(bitmapdata) file.write(cfgdata) header = struct.pack("<iii", 0x1234567A, # tag len(cfgdata), # length bitmaplen, # number of bytes in bitmap ) file.write(header) file.write(open(arcname, "rb").read())
This might be better introduced as part of the core rather than as a seperate recipe, as the customisation point doesn't alter the base operation, just provides a hook for the customisation.
