`git annex addurl` supports regular urls, as well as detecting videos that
|
|
quvi can download. We'd like to extend this to support extensible uri
|
|
handling.
|
|
|
|
Use cases range from torrent download support, to pulling data
|
|
from scientific data repositories that use their own APIs.
|
|
|
|
The basic idea is to have external special remotes (or perhaps built-in
|
|
ones in some cases), which addurl can use to download an object, referred
|
|
to by some uri-like thing. The uri starts with "$downloader:"
|
|
|
|
git annex addurl torrent:$foo
|
|
git annex addurl CERN:$bar
|
|
|
|
Problem: This requires mapping from the name of the downloader, which is
|
|
probably the same as the git-annex-remote-$downloader program implementing
|
|
the special remote protocol, to the UUID of a remote. That's assuming we
|
|
want location tracking to be able to know that a file is both available
|
|
from CERN and from a torrent, for example.
|
|
|
|
It would also be nice to be able to easily configure a regexp that normal
|
|
urls, if they match, are made to use a particular downloader. So, for
|
|
torrents, this would make matching urls have torrent: prefixed to them.
|
|
|
|
git config annex.downloader.torrent.regexp '(^magnet:|\.torrent$)'
|
|
|
|
It might also be useful to allow bypassing the complexity of the external
|
|
special remote interface, and let a downloader be specified simply by:
|
|
|
|
git config annex.downloader.torrent.command 'aria2c %url $file'
|
|
|
|
In this case, the UUID used would be the UUID of the web special remote, I
|
|
suppose?
