Flake8 Config in Pyls for Code Linting.

Update 2021-07-15: Note that pyls has been deprecated. There is new fork of it called pylsp, which is maintained by the community.

In my previous post, I have go over the basic setup to make vim-lsp work. However, I haven’t touch on an important part of writing code: linting. It turns out that configure it correctly is harder than I thought.
