The attached patch implements long option support for
Python. It changes the optstring found in
Modules/main.c, specifying brackets for the long name
of a corresponding option name. The patch is backward
compatible in that it doesn't change the behaviour of
_PyOS_GetOpt for any old format string, except on
[:()], which are explicitly excluded for matching an
option. This shouldn't break any code, though.

The patch is against Python 2.4.3.

The attached patch is against the current subversion trunk,
and implements long options with possible arguments after an
=-sign. It has partial matching for options, erroring out on
ambiguous matches of the command line arguments.

Please update the patch to follow Python C style guidelines
(PEP 7), especially use 8-space tabs to indent.

Also, it might be good to send a copyright assignment to the
PSF for a patch of this magnitude.

Otherwise, I think that this is a desirable feature, at
least for --help and --version.

I'll redo the patch with vim now, emacs doesn't like doing 8
spaces indents, at least as far as I can get it configured...

Anyway, I assign the copyright to any code contained in this
patch to the PSF.

Final patch which should conform to PEP-7 completely.

I actually wonder what the rationale for this patch is. The
command line options of Python seem very clear to me; I
don't see the need for long options.

This should be discussed on python-dev.

The rationale behind this patch is to enable python to
answer to --version and --help, which are pretty much
standard command-line options with GNU utilities, and
increasingly common amongst BSD utilities. I developed this
patch, answering to a request on c.l.p where people were
asking for Python to answer to --version, and thought I
could generalize it a bit so that long options can also be
used for other arguments.

I just posted a mail to python-dev explaining my rationale
behind this patch. Maybe you could answer there...

The latest patch takes into account all constructive ideas
that have been proposed on python-dev for this enhancement.

It implements /<opt> support on Windows for long options,
and adds ? as a possible option to get help.

Small extension to completely conform to Microsoft long-opt
semantics:

--<name>=<arg>

is equivalent to:

/<name>:<arg>

under Windows with the latest patch.

Rejecting as per python-dev discussion. There was a
pronouncement from Guido that only --help, --version and /?
for Win should be added.
