Silence stderr

[tweekmonster]

@petobens Could you see if this resolves your issues. I wasn't able to see any exceptions, but I did have a problem with empty error messages being emitted.

If you're still getting exceptions, could you give me a little more info such as what Python version you're using for nvim.

[petobens]

Thank you so much! (And sorry for being such a pain!). It seems to work :)

[tweekmonster]

It's no problem at all!

[petobens]

Terribly sorry to disturb you again. Mmm I just got a new exception:

[tweekmonster]

@petobens I'm unable to reproduce. Could you try updating the submodules?

git submodule update --init --recursive

[petobens]

I think i found a way to reproduce it (with the latest submodules). Create the following two files in your ~/Desktop/foo dir:

i) config.py

from collections import namedtuple

env = 'dev'
_constants = {'TMP_DIR': f'/tmp/{env}/'}
constants = (namedtuple('Constants', _constants)(**_constants))

ii) main.py

from config import constants

Now save main.py with :w (or simply open that file). In my case (hopefully in yours too) errors will appear. Thanks for the patience!

[tweekmonster]

I'm unable to reproduce this. Based on the info above, you could try this:

cat ~/Desktop/foo/main.py | /usr/local/bin/python3 /Users/pedro/git-repos/private/dotfiles/vim/bundle/repos/github.com/tweekmonster/impsort.vim/bin/impsort.py ~/Desktop/foo/main.py

This is the output I get:

constants,instance
__doc__,instance
__file__,instance
__name__,instance
__package__,instance

[petobens]

I'm getting the same output as you are.

Can you reproduce my error with the following init.vim file:

let $DOTVIM = expand('$HOME/.config/nvim')
if has('vim_starting')
    execute 'set runtimepath+=' . expand(
                \ '$DOTVIM/bundle/repos/github.com/Shougo/dein.vim')
endif

if dein#load_state(expand('$DOTVIM/bundle/'))
    call dein#begin(expand('$DOTVIM/bundle/'))
    call dein#add('tweekmonster/impsort.vim', {'on_ft' : 'python'})
    " call dein#add('tweekmonster/impsort.vim')
    call dein#end()
    call dein#save_state()
endif

filetype plugin indent on

It might have something to do with dein's on_ft? Thanks :)

[tweekmonster]

Sorry I didn't see this sooner. I don't use dein, so I wouldn't even know where to begin debugging if that's a problem. Does it work fine without on_ft? It may be easier for you to see if the problem persists without any other plugin enabled, dein included.

[petobens]

I''ll try to reproduce it without dein and report back. Thank you!
