Simple todo list syntax highlight for VIM

matrixvimrc

" --- matrixvimrc ---
" A minimal, distraction-free Vim configuration for 'zen' editing.

" --- CRITICAL COMPATIBILITY SETTING ---
set nocompatible

" --- Core Setup ---
set termguicolors


set backspace=indent,eol,start

" --- The 'Zen' Interface ---
set laststatus=0
" set noshowmode
set nonumber
set norelativenumber
set scrolloff=5
set tabstop=4
set shiftwidth=4
set autoindent

" --- Text Width and Visual Margin ---
" Enable auto-wrapping at 100 characters.
set textwidth=120

" --- THE FIX for the visual margin ---
" Instead of using the '+1' syntax, we programmatically generate a list
" of all columns from 101 to 1000 and tell Vim to highlight all of them.
" This is the most reliable way to create a shaded right-hand margin.
let &colorcolumn=join(range(&textwidth + 1, 1000), ',')

" --- The Color Scheme ---
highlight clear
if exists("syntax_on")
  syntax reset
endif
