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
