It does the same thing, but with __main__ instead of __zipmain__, and without needing the -z. So instead of "python -z foo.zip" you can just do "python foo.zip". This means you can use a reasonably cross-platform #! header that invokes Python via "env". If you tried to use -z with env, Andy's approach would either only work on BSDish platforms that support multiple options to a #! command, or else you'd have to ditch the "env" and hardcode the patht to Python. So not needing a command-line option improves the effective portability/usability of the executable zip file. Also, being able to run "python directory_to_be_zipped_later" also lets you test/develop your program without it needing to be zipped first. >On 9/11/07, Nick Coghlan <[EMAIL PROTECTED]> wrote: > > The local patch I have for PEP 366 is somewhat stale, and before I bring > > it up to date with SVN head, I'd like to close out the issue raised a > > while back regarding making zip files executable [1]. > > > > The original proposal was for a new command line switch, but PJE came up > > with a patch (attached to the roundup tracker item) that uses the > > existing import machinery to avoid the need for the extra command line > > switch (by checking if the argument is a valid sys.path entry before > > checking to see if it is an executable script). > > > > I personally like the idea (and PJE's approach), and the performance > > impact on script startup time appears to be negligible (although I > > haven't performed any high precision measurements - I'm just using the > > Linux time utility on a short test script with and without the patch). > > > > Are there any objections to my committing this? > > > > Cheers, > > Nick. > > > > [1] http://bugs.python.org/issue1739468 _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
