How to ensure that formatoptions *never* contains `r` or `o`?

问题

In vim, the filetype occasionally is set to a value that auto-populates formatoptions with r and o, two features that I do not like. What setting can I add to guarantee that under no circumstances will those characters appear in formatoptions?

回答1:

Modifying @sergio's answer slightly, you could use

autocmd Filetype * set fo-=r fo-=o

in your vimrc.

This removes 'r' and 'o' from 'formatoptions' whenever the filetype is set.

(Note that filetype detection has to be on, which can be set by :filetype on.)

回答2:

You could define an auto-command in ~/.vimrc to remove r and o format options from every file type:

autocmd CmdLineLeave,BufEnter * set fo-=r fo-=o
