To protect against running untrusted code accidentally,
you need to confirm to trust the .nvim directory the first time it is detected.
the trusted files or directories are recorded at ~/.local/state/nvim/trust.
Warning
Since there's almost no chance that a normal repo contains a .nvim directory,
I do not varify if the directory has been modified after being trusted.
Just in case that the .nvim is from remote, please be cautious.
You can also put Language config files in .nvim/langs.
I recommend you to use this feature to set language-specific options. Like This
Of course you can just use ftplugin
