爲什麼VIM看到一些文件作爲參數傳遞給CCTreeLoadXRefDBFromDisk

Question

autocmd VimEnter * if filereadable('cctree.out') | CCTreeLoadXRefDBFromDisk cctree.out | endif 

我收到錯誤消息：

E172: Only one file name allowed: CCTreeLoadXRefDBFromDisk cctree.out | endif 

Answer 1

它看起來像這樣命令把|作爲參數的一部分（這是除非一個指定-bar的時候默認定義命令，又一個奇怪的默認值）。嘗試

function s:TreeLoad(file) 
    if filereadable(a:file) 
     execute 'CCTreeLoadXRefDBFromDisk' fnameescape(a:file) 
    endif 
endfunction 
augroup VimrcTreeLoad 
    autocmd! 
    autocmd VimEnter * :call s:TreeLoad('cctree.out') 
augroup END
