What went wrong

ALE does not load my pylintrc when opening a second file with vim split. It works as expected when working on a single file (i.e. it uses the pylintrc) but when opening a second file via split, it doesn't and it reports pylint warnings that I had disabled in the config.

I have pasted above the ALEInfo from both buffers where you can see that for the first file it correctly uses the config while in the second it doesn't. Now that I think about it, it may in fact not be using the vimrc (and not the pylintrc as I thought) because for the first file it correctly reports only one linter (which I have set in my vimrc) while for the second it reports various linters (which is the default)

Reproducing the bug

1. Setup ALE to use a single linter (e.g. pylint)
2. Open a python file
3. Open a second python file via vim split
4. Observe that ALE in the second file has many linters enabled instead of one

It looks like there's something in your configuration which is changing your settings when you open files. Look through the plugins you have installed and your other script files for answers.

[sdb1228]

This happens for me as well and I use javascript instead of python.

[RyanSquared]

@sdb1228 what is your plugin list? can you reproduce this with a minimal amount of plugins installed?

[angrypie]

I have the same problem. For test purpose I have removed all configurations and plugins, except ALE and plugin manager, but problem still occur.

[RyanSquared]

@angrypie thanks; can you confirm that there's an inconsistency between :ALEInfo output for you as well?

[angrypie]

@RyanSquared oh, my bad. Have had b:ale_linters instead of g:ale_linters 🤦🏻‍♂️ I think @alpapado may have the same misconfiguration because of his statement:
"4. Observe that ALE in the second file has many linters enabled instead of one"

[alpapado]

@angrypie Yes that was indeed the issue. Nice catch :+1:
