Recent release `1.0.17` breaks ipython

See original GitHub issue

I am running ipython==5.8.0 on Ubuntu and with the recent release 1.0.17 breaks it:

$ ipython

It should be fixed now.

The issue appeared on IPython 5 only, which uses prompt_toolkit 1.0. Python 3 users were not affected because they get a more recent IPython version, which uses prompt_toolkit 2.0. (This was probably also the reason why I didn’t notice it myself.)

The issue was caused by a file prompt_toolkit/completion.py in ptk2 that became a directory in ptk3. Somehow, I had some leftovers of the 2.0 branch while doing the 1.0 release.

Thanks everyone for reaching out so quickly, and sorry for the past few hours!

Thanks for pointing out!! I’ll push a new release in a few minutes. (First trying to see where it went wrong.)
