I think ALE is not running flake8 w/ appropriate arguments when a file is saved

[AmagicalFishy]

I added a file, .config/flake8 with appropriate max-line-length arguments to change that to 100 lines. Since, as of October, flake8 no longer supports user-level configuration files, I have g:ale_python_flake8_options = "--config=$HOME/.config/flake8" to my .vimrc.

ALE continues to flag lines that are over 79 characters in addition to lines that are over 100 characters.

• When I open the file, the appropriate lines (over 100 characters) are flagged
• When I save the file, then the lines that are over 79 characters are also flagged
• I have specifically only enabled flake8 in my .vimrc—ensuring that it isn't some other linter that's flagging the lines
• The commands run in ALEInfo appropriately use the --config flag
• Running flake8 --config=$HOME/.config/flake8 manually gives the correct/expected results, so this is isolated to ALE I think
• I've tried g:ale_linters_explicit = 1 just in case it was still another linter somewhere
• As far as I can tell, there are no other flake8 configuration files, but this shouldn't matter since the --config flag should override all other configurations

I think the problem is somewhere in ALE when a file is saved (i.e., everything works correctly when ALE runs after the file is opened, but the configuration isn't considered when the file is saved), but I have no idea where to look.

Anyone else experience something like this, or have any suggestions for direction?

I am unable to reproduce this issue on my setup. Following exact steps provided I get only lines over 100 properly flagged when opening and when saving a python file.

Can you provide the output of ALEInfo? that may provide more information like specific configurations. Also version of flake8, vim/neovim. Finally make sure you are using latest ALE from master that has many fixes.

... please pretend this post never happened. I looked at the output again in ALEInfo and saw that the error was correct (flagging lines over 100 characters). What confused me so much was that everything looked normal and well. After some searching, I found that I also had Syntastic installed. After deleting Syntastic, everything's working as intended (so the E501 of the 79 lines was Syntastic -__-)

Sorry to waste your time
