I'm not sure why this started to happen but recently vim seems to have begun autowrapping lines when in insert mode. It's pretty annoying.

I use the following modules

'vim-ruby/vim-ruby'
'rodjek/vim-puppet'
'romainl/Apprentice'
'plasticboy/vim-markdown'

I also have the following set

set wildmode=longest,full
set textwidth=80
set autoindent

It pretty much happens in all files so filetype seems to not matter. The full vimrc can be seen here https://pastebin.com/1kpUmXFd

    Does this answer your question? Adding new characters cause splitting line into many lines – Jake Grossman Sep 25 at 22:25

    Welcome to Vi and Vim, Biff! You can usually work around that by setting :set tw=0. But usually Vim will wrap lines depending on the file type you're editing. Can you take a look and share what file type you're editing when this happens? Also post the result of :set ft? and :set fo?, since the former can confirm the file type and the latter is involved in the decisions on when to wrap long lines after the 'textwidth' is reached... – filbranden Sep 25 at 22:44
  • Well the tw being set to 80 like I have has been set for decades now without issue. It's only recently upon entering insert mode or writing text that the wrapping happens. It's every ft. The fo is formatoptions=croql – Biff Sep 26 at 1:12
  • If you have fo=croql, then it means only comments will be broken at 'textwidth'. Is it possible that what you're seeing is only happening on lines that have comments? If you remove the c from that option (:set fo-=c), then Vim should stop breaking lines at tw when those lines are comments... – filbranden Sep 26 at 6:14

Remove the tw=79 and textwidth=80 from you .vimrc and Vim will not wrap lines.

    This would be a stronger answer if it included an explanation: why do these steps solve the problem? In the comments, OP mentions they've had these settings for a while, and only recently has the problem emerged – D. Ben Knoble Sep 27 at 14:43
