I would like to have hex codes been displayed inline, no matter what filetype is activated in the current session.
So far I've found something existent and suitable for my needs: https://github.com/skammer/vim-css-color/blob/master/after/syntax/css.vim
I tried to recode the syntax file to effect all types of code, but didn't get it in the end. To be honest, I've just no clue about coding for vim. Could anyone help? I would be really glad if someone could... =/
