After installing version 2.0.1 in a clean environment, I get the following error when opening a file and pressing Shift-V:

Thanks for reporting @davidbrochart, I'm working on a fix!

jonathanslenders commented 6 years ago

Hi @davidbrochart, this should be fixed in the following prompt_toolkit commit: https://github.com/jonathanslenders/python-prompt-toolkit/commit/5e04f58e70447ecfa83d6f93ec3590d3bafcaec0

If you have time, could you try to upgrade both prompt_toolkit and pyvim to the latest master commit and try again? Thanks a lot!

davidbrochart commented 6 years ago

I tried with latest prompt_toolkit and pyvim and the error is gone, thanks. However I noticed that line selection (Shift-v) doesn't highlight the text.

jonathanslenders commented 6 years ago

Right, that is another bug. Thanks for noticing!

jonathanslenders commented 6 years ago

The line selection issue should be fixed now: https://github.com/jonathanslenders/python-prompt-toolkit/commit/677190f37e064bba83474cae3e277681b3970cfe

davidbrochart commented 6 years ago

Yes it is. Thanks!
