@bytegolang For nvim, you have two options, either you add it to your init.vim configuration or you add it to the ftdetect folder.

I like using ftdetect because it keeps the configuration separated per file type, so in this case I'd copy this file to ~/.config/nvim/ftdetect/go.vim this way this configuration is loaded when Go files are detected.

@MarioCarrion thank you！！！
