Per <pybugs.pho...@safersignup.com> added the comment: On POSIX the interpreter will be read from the first line of a file. On Windows the interpreter will be read from the Registry HKEY_CLASSES_ROOT\.<file-extension> .
So the correct way to associate a interpreter to a file is to invent a file-extension for every interpreter. Like /usr/bin/python /usr/bin/python3 and /usr/bin/python3.1 on POSIX, there should be .py .py3 and .py31 on Windows! I attached a example-registry-patch to register extensions for 2.5, 2.6 and 3.1 . If you want to use it, you need to adjust the paths! I propose to change all Python-Windows-installer to install versioned extensions. If you want a switcher application, it should read the first line of the script and match it against ".*/python(.*)$". So the default POSIX "#!/usr/bin/python3.1" can be kept unchanged. With that rexex the app-path can be read from "HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\<regex-match>\InstallPath\". BTW. It would be nice if Python would call itself "Python 3.1" instead of "python" in the "Open with..."-list! The current naming is problematic if you install more than one Python version. ---------- nosy: +phobie Added file: http://bugs.python.org/file17481/hklm_python_extensions.reg _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue4015> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
