[Distutils] Problem adding a new setup command..

[Etienne Robillard]

Hi there,

I'm a new setuptools user. I think setuptools is very
good, and I'm currently using it for a personal
project. [1]

However, I'm experimenting a small issue when trying
to use a new setup command like so:
 
 $ python setup.py install_media 
 Distribution.parse_config_files():
  reading setup.cfg
options (after parsing config files):
option dict for 'egg_info' command:
  {'tag_build': ('setup.cfg', 'p1'),
'tag_svn_revision': ('setup.cfg', '0')}
options (after parsing command line):
option dict for 'aliases' command:
  {}
option dict for 'egg_info' command:
  {'tag_build': ('setup.cfg', 'p1'),
'tag_svn_revision': ('setup.cfg', '0')}
option dict for 'install_media' command:
  {'args': ('command line', [])}
running install_media
Distribution.get_command_obj(): creating
'install_media' command object
  setting options for 'install_media' command:
    args = [] (from command line)
Traceback (most recent call last):
  File "setup.py", line 143, in <module>
    zip_safe=(sys.version >= 2.5)
  File
"/opt/python25/lib/python2.5/distutils/core.py", line
151, in setup
    dist.run_commands()
  File
"/opt/python25/lib/python2.5/distutils/dist.py", line
974, in run_commands
    self.run_command(cmd)
  File
"/opt/python25/lib/python2.5/distutils/dist.py", line
992, in run_command
    cmd_obj = self.get_command_obj(command)
  File
"/opt/python25/lib/python2.5/distutils/dist.py", line
879, in get_command_obj
    self._set_command_options(cmd_obj, options)
  File
"/opt/python25/lib/python2.5/distutils/dist.py", line
919, in _set_command_options
    % (source, command_name, option))
distutils.errors.DistutilsOptionError: error in
command line: command 'install_media' has no such
option 'a     rgs'

Here's the setuptools.Command subclass:

from setuptools import Command
class install_media(Command):
    description = "Install app-specific media files"
    command_consumes_arguments = True
    # List of options for this command
    user_options = [
        # Perhaps the better option is to use the
'--prefix' arg.
        # ('with-docroot=', None, 'Install media files
to this directory'),
        ('with-apps=', None,
         "Search theses subdirs for media files
(comma-separated list)")
    ]
    def initialize_options(self):
        pass
    def finalize_options(self):
        pass
    def run(self):
        return self._find_media_files()
    def _find_media_files(self):
        pass


Any insightful hints how to debug this problem? 
The Big Idea was to add a new setup command (named
install_media) which could presumely allow things 
like:

 $ python setup.py install_media --prefix=/var/www
--with-apps=foo,bar


Thanks in advance,

Etienne
