vim创建程序文件自动添加头部注释

修改 ~/.vimrc，在文件最后添加以下内容：

" add header comments for .h .c .hpp .cpp .mk .sh new file
" auto call SetTitle func
autocmd BufNewFile *.[ch],*.hpp,*.cpp,Makefile,*.mk,*.sh,*.py exec ":call SetTitle()"

" add comment for cpp
func SetComment_ch()
	call setline(1,"/*================================================================")
	call append(line("."),   "*   Copyright (C) ".strftime("%Y")." * Ltd. All rights reserved.")
	call append(line(".")+1, "*   ")
	call append(line(".")+2, "*   File name   : ".expand("%:t"))
	call append(line(".")+3, "*   Author      : longbin")
	call append(line(".")+4, "*   Created date: ".strftime("%F %T"))
	call append(line(".")+5, "*   Description : ")
	call append(line(".")+6, "*")
	call append(line(".")+7, "*===============================================================*/")
	call append(line(".")+8, "")
	call append(line(".")+9, "")
endfunc

" add comment for shell,Makefile
func SetComment_sh()
	call setline(3, "#================================================================")
	call setline(4, "#   Copyright (C) ".strftime("%Y")." * Ltd. All rights reserved.")
	call setline(5, "#   ")
	call setline(6, "#   File name   : ".expand("%:t"))
	call setline(7, "#   Author      : longbin")
	call setline(8, "#   Created date: ".strftime("%F %T"))
	call setline(9, "#   Description : ")
	call setline(10, "#")
	call setline(11, "#================================================================")
	call setline(12, "")
	call setline(13, "")
endfunc
