annoying red blocks in neovim

Question

im using Neovim from my WSL terminal. I've been exploring the multiple plugins of this amazing open source project and this made me change my init.vim, a lot. Now i've messed it up and i don know how to make him 'normal'.

Those are my init.vim plugins

:

And those are the changes i've aded to it

The problem

now, everytime o try to open a python file, it higlights some redblocks. I want to take them out but i dont know how to do this, here's an example of how my code is right now:

How can i remove those redblocks? Any help is more than welcome

Note

I know that my init.vim is a mess, i also need to discover how can i copy stuff from neovim to clipboard.

Answer 1

Those are trailing whitespaces highlighted as error.

Most probably they are from vim-polyglot plugin:

https://github.com/sheerun/vim-polyglot/blob/4af1321588c7dcb718022226cb27ec325973c2f0/syntax/python.vim#L160

To "fix" it:

1. Either remove those spaces from the file
2. Or add let g:python_highlight_space_errors = 0 to your config.

Answer 2

Regarding copy-paste, in Linux adding,
set clipboard=unnamedplus

in init.vim makes neovim use the system's clipboard.

You could also try,
set clipboard=unnamed
