What's the use of this vertical column in Thoughtbot's vim configuration


Thoughtbot’s vim configuration has this vertical column in the editor. In the .vimrc file this is configured with:

set textwidth=80
set colorcolumn=+1

I was wondering what’s the use of this.

It’s to warn you if a line exceeds 80 characters, so as to meet thoughtbot’s coding style rules.

oh I see, thanks andyw8 for the information
