NameError Traceback about pathfinder.vim HOT 5 CLOSED

Can you try again? I just tried reproducing your bug. Started off with a clean .vim and .vimrc and installed minplug as given in https://github.com/Jorengarenar/minPlug. It installed flawlessly for me and also working. So the problem does not seem to me with pathfinder.vim or minplug which might make it harder to solve.
In case it matters I am using Arch with everything updated to latest as of today.

Edit - Can you try again with a different plugin manager. Which might make it easier to diagnose where the problem lies

from pathfinder.vim.

I've done the following now:

NOTE: Before this, I've run rm -rf ~/.vim

1. Install vim-plug:

$ curl -fLo ~/.vim/autoload/plug.vim --create-dirs \
    https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

2. Setup ~/.vim/vimrc like so:

call plug#begin('~/.vim/plugged')

Plug 'AlphaMycelium/pathfinder.vim'

call plug#end()

3. Install plugins:

:PlugInstall

4. Startup Vim, and get the following:

Thanks for following through
I think the problem is the same as this one psf/black#1347. It seems to me we might have the same bug.
The related issue vim/vim#4705
And the change https://github.com/vim/vim/releases/tag/v8.2.0578
Also it might be I am not being able to reproduce your problem on vanilla arch because there is a patch in vanilla arch vim which doesn't let this happen. Since I cannot reproduce it can you make two edits and let me know if that solves it for you?

1. In ~/.vim/plugged/pathfinder.vim/plugin/main.vim line 12 change endpython to Endpython
2. Same file line 20 change endpython to Endpython

from pathfinder.vim.

I apologize for the delayed response, and again because I know this doesn't help determine the root cause, but I've updated to the latest patch (8.0905) and the plugin is working as intended.

I noticed that you mentioned the fix being in patch 0578, but note that the version I mentioned using was 0579:

$ vim --version
VIM - Vi IMproved 8.2 (2019 Dec 12, compiled Apr 14 2020 22:30:44)
Included patches: 1-579
...

Because my upgrades have been a detriment towards potentially solving the problem, albeit with possibly 2 characters as well, I'd be happy to help by reverting my update and trying what you'd mentioned above. However, I don't want to go to the effort if you don't need me to. Let me know @aryabhatta-dey.

from pathfinder.vim.

R e thanks for replying back.. the delay is nothing. I am glad that it's working for you. Then I will go ahead and close the issue. Hope you find the plugin helpful and do drop by to report on anything new or for PRs. Hope to see you again:)

PS - I meant in 578 they introduced the breaking change. It seems somewhere along the line in a later patch they have reverted to allow both endpython and Endpython. That is why I couldn't reproduce it on my system and why it got fixed for you automatically. Still this was helpful issue as in case someone else runs in a similar issue in the future they can easily solve the bug
