expression drill-down gone?

[davidszotten]

Hi,

Thanks for a great plugin!

While the diffs are super helpful, it looks like we lose the very handy drill-down output:

$ cat test.py
a = [1, 2, 3]
b = [1, 2]

def test_a():
    assert len(a) == len(b)

without plugin

    def test_a():
>       assert len(a) == len(b)
E       assert 3 == 2
E        +  where 3 = len([1, 2, 3])        <-- i miss these
E        +  and   2 = len([1, 2])

with plugin

    def test_a():
>       assert len(a) == len(b)
E       assert left == right failed.
E         Showing split diff:
E
E         left:  3
E         right: 2      <--  really nice!

perhaps @nicoddemus has any advice/ideas on how to make this possible?

Good catch, totally forgot about this! It should be possible, but I'll take a closer look next week.

@darrenburns any news on this front? Would you like some help on this enhancement?

[darrenburns]

Hi @nickpresta, I took a brief look into this a while back and found it to be trickier than I'd hoped, so I haven't made any progress on it. Any help would be greatly appreciated :)
