How to check whether vim has enabled line autobreak at 80 characters or not?

Hi my vim automatically insert a newline character after 80 character, which is not my intended behavior. However, I cannot find any line width config in my vimrc file.

How to check whether some config is enabled for this? I want to disable this auto-line-break feature.

Thanks to @romainl reminder, here is the output of the command ":verbose set fo tw":

  formatoptions=tcq                                                                                                                                                      
        Last set from ~/.vim/view/~=+Downloads=+c.txt= line 68                                                                                                           
  textwidth=79                                                                                                                                                           
        Last set from ~/.vim/plugin/python.vim line 20

So…

  • To reiterate what I wrote in the comments section, automatic line breaks happen when you have t in :help 'formatoptions' and :help 'textwidth' is set to a non-zero value. Individually, those conditions don't lead to automatic line breaks, it is only when they are both true that you get automatic line breaks.
  • The t in formatoptions is not a problem in and of itself. It is part of of the default value anyway so you can pretty much forget about it.
  • You get those automatic line breaks because textwidth is set to 79 in ~/.vim/plugin/python.vim. Change its value to 0 to disable the feature.

But the interaction of those two files is worrying so I think you should take a look at this document.

You might need to configure the following options in your .vimrc

  • wrap
  • textwidth Maximum width of text that is being inserted. A longer line will be broken after white space to get this width. A zero value disables this.
  • wrapmargin Number of characters from the right window border where wrapping starts. When typing text beyond this limit, an EOL will be inserted and inserting continues on the next line.
