vim 配色

添加 c 函数名高亮配置

sudo vim /usr/share/vim/vim81/syntax/c.vim

在最后添加：

"highlight Functions
syn match cFunctions "\<[a-zA-Z_][a-zA-Z_0-9]*\>[^()]*)("me=e-2
syn match cFunctions "\<[a-zA-Z_][a-zA-Z_0-9]*\>\s*("me=e-1
hi def link cFunctions Function

vim 默认配色方案

vim /usr/share/vim/vim81/syntax/syncolor.vim

" Many terminals can only use six different colors (plus black and white).
" Therefore the number of colors used is kept low. It doesn't look nice with
" too many colors anyway.
" Careful with "cterm=bold", it changes the color to bright for some terminals.
" There are two sets of defaults: for a dark and a light background.
