- correctly handles add_copy mode and configuration,
- add option top force 'copy' mode (since the default had been changed
in between from 'copy' to 'move' this is now needed),
- fixes assumption in one test that the default is 'copy' (in other
words the test was broken and ensuring that the functionality was broken
too.),
- do not try to delete the source when it is an URL.
* This fixes the logic in the `pubs add` command so that an arxiv ID doesn't
overwrite a DOI. This also changes the logic so that if an invalid DOI, ISBN,
or arXiv ID is provided the program will raise an error.
* The code now uses the bibtexparser package to generate the bibtex file for
arxiv papers.
* A dedicated exception is added for references that can't be found.
This allows the user to add a reference via an arXiv ID similarly to how a reference can be added
from a DOI or ISBN. If the arXiv ID has a DOI associated with it (according to the arXiv server),
the DOI will be used. If it does not (perhaps the paper is unpublished), then a bibtex entry will
automatically be generated from the reference's metadata.
Note that a potential issue with this addition is that if a paper is added before it is published
(i.e., there is no DOI associated with it), and the paper is later published, the updated
information will have to be manually added.
This involved many changes, some side effects of the change include:
- remove of all `u"abc"` forms, in favor of
`from __future__ import unicode_literals`. Their usage was
inconsistent anyway, leading to problems when mixing with
unicode content.
- improve the tests, to allow printing for usecase even when
crashing. Should make future test easier. This is done with a
rather hacky `StdIO` class in `p3`, but it works.
- for some reason, the skipped test for Python 2 seems to work
now. While the previous point might seem related, it is not clear
that this is actually the case.
