Hard to say what happens with master failing ... i'll wait for it to be fixed and rebase :)

[joernhees]

👍 sorry for that... #550

[joernhees]

py3.4:

TypeError: unorderable types: URIRef() < AlternativePath()

i guess this is a symmetry problem... if the first operand is not a Path it breaks... should we maybe move the whole comparison code to Node or Identifier and make Path a subclass?

also, shouldn't https://github.com/RDFLib/rdflib/blob/master/rdflib/term.py#L171 actually raise NotImplemented() instead of returning it?

[gromgull]

Don't ask me why, but returning is correct: https://docs.python.org/2/library/constants.html#NotImplemented

I'll look into py3, but not today :)

[joernhees]

ah i didn't know it's actually a keyword and confused it with https://docs.python.org/2/library/exceptions.html#exceptions.NotImplementedError which would need to be raised...

[gromgull]

The missing part was adding @functools.total_ordering - that fixes py3.4, but breaks 2.6 where it doesn't exist :(

When can we kill 2.6 support? :)

[joernhees]

i guess with rdflib 5.0.0 but for now i just fixed it by also defining the other comps...

one other thing i noticed looking at this again though: if possible repr is meant to return something that you can paste into a python interpreter re-creating the object... do you see an easy way to change the __repr__ methods of the current Path objects in that way? (i didn't)
