cocopp.archiving.ListOfArchives

List of URLs or path names to COCO data archives available to this user.

Elements can be added with append and deleted with the respective list operations. After any of these operations, the current state can be made "permanent" with save.

Archives created with create are automatically added to ArchivesLocal to find splattered archives more easily, archives retrieved from a remote location with get are added to ArchivesKnown.

Elements of the list are meant to be used directly as argument to get.

>>> import cocopp.archiving as ar
>>> ar.ListOfArchives.lists()  # doctest:+ELLIPSIS
{...

returns all available archive lists.

To reassign a given list:

>>> l = ar.ListOfArchives('test')
>>> l[:] = ['p2', 'p1']  # re-assign a new value to the list
>>> l.sort()  # `list` builtin in-place sort method
>>> l.save()  # doctest:+SKIP

To save the list, a listing name needs to be given on instantiation. Two inherited classes are

>>> ar.ArchivesKnown() and ar.ArchivesLocal()  # doctest:+ELLIPSIS
[...

where the former contains downloaded "inofficial" archives. To add all locally created archives within the user home directory tree (CAVEAT: the search may take a while):

>>> al = ar.ArchivesLocal()  # based on user home
>>> al._walk()  # doctest:+SKIP
>>> # al._save_walk()  # add found paths (permanently) to the ArchivesLocal class

Details: duplicates are removed during save. Path names are stored as absolute path names (OS-dependent).

TODO: should we be able to generate a list on the fly? Figure out usecase with _walk?

TODO-decide: usecase, when to decide setting search_folder?
