have text longer than a vim windows displayed on several lines

Question

I'm trying to have text longer than a vim windows displayed on several lines. For this, I tried to follow the advice of this blog by entering set wrap in the .vimrc file but nothing changes and the text is still longer than the window width. Is there another function in my .vimrc file that desables it. Here is the .vimrc file:

The help :h 'wrap' tells us that the option is local to a window. So setting it up in your vimrc will not affect the windows you will open while using vim.

You have several solutions then:

• Manually using :set wrap on windows where you need the option enabled.

• Using an autocommand to set the option everywhere:

  augroup wrap
    autocmd!
    autocmd BufWinEnter * setlocal wrap
  augroup END
  

• Using a ftplugin to set the option for the filetypes you need. For example for markdown files create ~/.vim/after/ftplugin/markdown.vim and put setlocal wrap in it.

See :h autocmd, :h autocmd-events and :h ftplugin
