interactive_open should now be invoked with at least the list of
targets and optionally the command to open the targets with.
This allows beets-play to pass multiple file paths directly to
the configured command.
The changes to the existing invocations are pretty trivial in
order to comply to this refactor.
interactive_open() takes a target and an optional command, if it does not
receive a command then it uses open_anything().
It parses command and lexes it with shlex.split(), revieling the client
from that task.
"config -e" command uses it, and gives a better error message in case of
problem. "play" plugin uses it as well, as side-effect being that the
command is now interactive, as requested in issue #1321.
Fix issue #1321.
This puts the OrderedEnum generic class next to where it is actually used. It
also refers to the recipe it is taken from on docs.python.org. I also took the
opportunity to give this a capitalized name (since it's a proper type).
This is not really critical since list(Type)[i] works just as well. This fixes
a couple other problems from the enum transition:
- The name of TYPES was not really consistent with its new role as an enum
type. Renamed this ImageType.
- Fix a rather egregious bug in embedart (undefined reference to Image).
