vim/vim自动添加头文件的配置

以下代码添加到options.lua中，应该用lua的语法来写，但是我不擅长，只能在lua中调用vimscript的代码了

vim.cmd([[
autocmd BufNewFile *.cpp,*.[ch],*.sh,*.java,*.go exec ":call SetTitle()"
"""定义函数SetTitle，自动插入文件头
func SetTitle()
    "如果文件类型为.sh文件
    if &filetype == 'sh'
        call setline(1,"\#########################################################################")
        call append(line("."),   "\# File Name:    ".expand("%"))
        call append(line(".")+1, "\# Author:       jili")
        call append(line(".")+2, "\# mail:         [email protected]")
        call append(line(".")+3, "\# Created Time: ".strftime("%c"))
        call append(line(".")+4, "\#########################################################################")
        call append(line(".")+5, "\#!/bin/bash")
        call append(line(".")+6, "")
    else
        call setline(1, "/* ************************************************************************")
        call append(line("."),   "> File Name:     ".expand("%"))
        call append(line(".")+1, "> Author:        JiLi")
        call append(line(".")+2, "> mail:          [email protected]")
        call append(line(".")+3, "> Created Time:  ".strftime("%c"))
        call append(line(".")+4, "> Description:   ")
        call append(line(".")+5, " ************************************************************************/")
        call append(line(".")+6, "")
    endif
    "新建文件后，自动定位到文件末尾
    autocmd BufNewFile * normal G
endfunc
]])

vim.cmd([[
autocmd BufNewFile *.h,*.hpp exec ":call AddHHeader()"
func AddHHeader()
    let macro = "_".toupper(substitute(expand("%"), "[/.]", "_", "g"))."_"
    "normal o
    call setline(9, "#ifndef ".macro)
    call setline(10, "#define ".macro)
    call setline(11, "")
    call setline(12, "#endif  // ".macro)
endfunc
]])

-- 保存指针位置
vim.cmd([[
  if has("autocmd")
  autocmd BufReadPost *
  \ if line("'\"") > 0 && line("'\"") <= line("$") |
  \ exe "normal g'\"" |
  \ endif
  endif
]])
