可以定义gf命令的自定义变体，如果光标下的文件不存在，则打开新的缓冲区：

:noremap <leader>gf :e <cfile><cr>

其中:e命令可以用:tabe（以在单独的选项卡中打开新文件的缓冲区）或另一个文件打开命令替换。
也可以只在光标下创建一个名称为的文件，而不打开它;请看我对类似问题“Create a file under the cursor in Vim”的回答。

gf->在新选项卡中打开文件
cf->创建文件（如果不存在）并在新选项卡中打开

nnoremap gf <C-W>gf 
noremap <leader>cf :call CreateFile(expand("<cfile>"))<CR>
function! CreateFile(tfilename)

    " complete filepath from the file where this is called
    let newfilepath=expand('%:p:h') .'/'. expand(a:tfilename)

    if filereadable(newfilepath)
       echo "File already exists"
       :norm gf
    else
        :execute "!touch ". expand(newfilepath)
        echom "File created: ". expand(newfilepath)
        :norm gf
    endif

endfunction

nnoremap <silent> gf :call JumpOrCreateFile()<CR>

function! JumpOrCreateFile()
 " Get the filename under the cursor
 let filename = expand("<cfile>")

 " Expand the tilde in the file path
 let expanded_filename = expand(filename)

 " Check if the file path starts with "./"
 if expanded_filename =~# '^\.\/'
   " Get the current directory of the editing file
   let current_directory = expand('%:p:h')

   " Create the full path by appending the relative file path
   let expanded_filename = current_directory . '/' . expanded_filename
 endif

 " Check if the file exists
 if !filereadable(expanded_filename)
   " Prompt the user for file creation with the full path
   let choice = confirm('File does not exist. Create "' . expanded_filename . '"?', "&Yes\n&No", 1)

   " Handle the user's choice
   if choice == 1
     " Create the file and open it
     execute 'edit ' . expanded_filename
   endif
 else
   " File exists, perform normal gf behavior
   execute 'normal! gf'
 endif
endfunction
