VI Improved is a common derivate of the default editor on Unix-like systems. Usually, $EDITOR is also set to vi or vim.
vi is available everywhere, but vim is not.
A quick configuration which you can use to get basic stuff like syntax coloring, ready made to past into your .vimrc:
set nocompatible syntax on filetype plugin indent on set hlsearch set history=50 set showmode set showcmd cabbrev Wq wq cabbrev W w colorscheme desert
The desert colorscheme will let you read comments (which are normally dark-blue) also on wrong-configured terminals and looks pretty good elsewhere too.
A more extended Configuration
Basically like the Minimalistic, but adds some minor tweaks like bs=2 to avoid some terminal backspace key issues, a fixed tabwidth of 4 spaces, a shiftwidth of 4, so if you use the '>' keys it will be a tab and not spaces. And of course a function key shortcut for pastetoggle so you can paste in code without getting to strange intends
set nocompatible set bs=2 set ts=4 set shiftwidth=4 set noexpandtab set ruler syn on filetype plugin indent on set autoindent set showmatch set showcmd set showmode set hlsearch set pastetoggle=<F11> set nolbr colorscheme desert " Show Numbers On/Off map <F10> :call Number_on_off()<CR> let number_mode = 0 " 0 = normal, 1 = show number func! Number_on_off() if g:number_mode == 0 set nu let g:number_mode = 1 else set nonu let g:number_mode = 0 endif return endfunc
autointent is something I like, some people hate it if vim automatically intents code.
