介绍如何在macOS系统上安装和配置Vim,一个功能强大的文本编辑器,广泛用于编程和文本编辑。

" Configuration file for vim
set modelines=0     " CVE-2007-2438

" Normally we use vim-extensions. If you want true vi-compatibility
" remove change the following statements
set nocompatible    " Use Vim defaults instead of 100% vi compatibility
set backspace=2     " more powerful backspacing

" Don't write backup file if vim is being called by "crontab -e"
au BufWrite /private/tmp/crontab.* set nowritebackup nobackup
" Don't write backup file if vim is being called by "chpass"
au BufWrite /private/etc/pw.* set nowritebackup nobackup

colorscheme default     " 设置颜色主题

set number              " 显示行号
