   conda.core.index.LAST_CHANNEL_URLS


.. py:function:: check_allowlist(channel_urls)


.. py:data:: LAST_CHANNEL_URLS
   :value: []

   

.. py:function:: get_index(channel_urls=(), prepend=True, platform=None, use_local=False, use_cache=False, unknown=None, prefix=None, repodata_fn=context.repodata_fns[-1])

   Return the index of packages available on the channels

   If prepend=False, only the channels passed in as arguments are used.
   If platform=None, then the current platform is used.
   If prefix is supplied, then the packages installed in that prefix are added.


.. py:function:: fetch_index(channel_urls, use_cache=False, index=None, repodata_fn=context.repodata_fns[-1])


.. py:function:: dist_str_in_index(index, dist_str)


.. py:function:: _supplement_index_with_prefix(index, prefix)


.. py:function:: _supplement_index_with_cache(index)


.. py:function:: _make_virtual_package(name, version=None, build_string=None)


.. py:function:: _supplement_index_with_features(index, features=())


.. py:function:: _supplement_index_with_system(index)

   Loads and populates virtual package records from conda plugins
   and adds them to the provided index, unless there is a naming
   conflict.
