AttributeError with missing email in authors entry

[blueyed]

When using no email with entries in authors (authors = ["Alice"]),
poetry -vvv build fails:

  [AttributeError]                            
  'NoneType' object has no attribute 'group'

I think the email should be allowed to be empty, which means that this should not crash.

If you look at the documentation (https://poetry.eustace.io/docs/pyproject/#authors), it is specified that each author must be in the form name <email>

[blueyed]

What about name <email|URL> then maybe alternatively?
I do not want to put my email everywhere when it's not really necessary.

@blueyed Commit 5b14bd1 in the develop makes the email address optional. It will be available in the next 0.9.0 release.

[sdispater]

Release 0.9.0 is out!
