Is there a way to apply gruvbox color scheme for standard text files?

Like, all program files are syntax highled by this plugin for vim. But my I/O files are standard text files.

So, how to apply colour scheme for text files?

There is no such thing as a "standard text file". foo.c and bar.json are both "text files" but:

• their file extension and possibly various other properties and heuristics allow text editors to decide if they are C files, or JSON files, or whatever,
• their content follows a specific syntax that text editors know and use for syntax highlighting.

If your text editor can't figure out the filetype of a given file baz, then it will have a hard time highlighting its syntax.

So you have four scenarios…

1. It is possible to detect the type of the file and its content follows a specific syntax.

   You need to tell Vim how to detect the filetype, see :help new-filetype, and either assign it an existing syntax, see :help 'syntax', or create your own, see :help syntax.txt.

2. It is not possible to detect the type of the file but its content follows a specific syntax.

   You need to assign a filetype manually, see :help 'filetype', and either assign it an existing syntax, see :help 'syntax', or create your own, see :help syntax.txt.

3. It is possible to detect the type of the file but its content doesn't follow a specific syntax.

   Well, there is no syntax to highlight so it's GAME OVER.

4. It is not possible to detect the type of the file and its content doesn't follow a specific syntax.

   GAME OVER again.
