# Basic use
From python3's toplevel:
## Remote (failure)
``` Python
# remote repository
origin_url = 'https://www.mercurial-scm.org/repo/hello'
# local clone
directory = '/home/storage/hg/repo/hello'
import logging
logging.basicConfig(level=logging.DEBUG)
from swh.loader.mercurial.tasks import LoadMercurialTsk
t = LoadMercurialTsk()
t.run(origin_url=origin_url, directory=directory, visit_date='2016-05-03T15:16:32+00:00')
```
## local directory (failure)
Only origin, contents, and directories are filled so far.
Remaining objects are empty (revision, release, occurrence).
``` Python
project = '756015-ipv6'
directory = '/home/storage/hg/repo/%s' % project
origin_url = 'https://%s.googlecode.com' % project
import logging
logging.basicConfig(level=logging.DEBUG)
from swh.loader.mercurial.tasks import SlowLoadMercurialTsk
t = SlowLoadMercurialTsk()
t.run(origin_url=origin_url, directory=directory, visit_date='2016-05-03T15:16:32+00:00')
```
## local archive (failure)
``` Python
project = '756015-ipv6-source-archive.zip'
archive_path = '/home/storage/hg/repo/%s' % project
origin_url = 'https://%s-archive.googlecode.com' % project
import logging
logging.basicConfig(level=logging.DEBUG)
from swh.loader.mercurial.tasks import SlowLoadMercurialArchiveTsk
t = SlowLoadMercurialArchiveTsk()
t.run(origin_url=origin_url, archive_path=archive_path, visit_date='2016-05-03T15:16:32+00:00')
