VIM獲取E488尾隨字符

Question

我嘗試使用F4添加作者和其他信息。

但是當我打開* .c或其他文件（非* .sh），並且推F4時，它將顯示E488尾隨字符。

此外，當試圖更新信息時，它符合E20標記未設置。

而更多的問題，當我嘗試使用 let suff = expand("%:e")獲取Java文件擴展名，然後if suff == "java"，發現SUFF不等於「Java」的，爲什麼呢？

這是我的VIM配置：

" Add Author Information 
map <F4> :call TitleDet()<CR>'s 

function AddTitle() 
    call append(0,"/*========================================") 
    call append(1,"#") 
    call append(2,"# Author: xxx ") 
    call append(3,"#") 
    call append(4,"# Email: xxx@gmail.com") 
    call append(5,"#") 
    call append(6,"# Last modified: ".strftime("%Y-%m-%d %H:%M")) 
    call append(7,"#") 
    call append(8,"# Filename: ".expand("%:t")) 
    call append(9,"#") 
    call append(10,"# Description: ") 
    call append(11,"#") 
    call append(12,"======================================*/") 
    call append(13,""); 
    echohl WarningMsg | echo "Successful in adding the copyright." | echohl None 
endfunction 


function AddShellTitle()

    call append(1,"#")

    call append(11,"#") 
    call append(12,"#========================") 
    echohl WarningMsg | echo "Successful in adding the copyright." | echohl None 
endfunction

function TitleDet() 
    let n=1 
    let suff = expand("%:e") 
    while n < 10 
     let line = getline(n) 
     if suff != "sh" 
      if line =~ '^\#\s*\S*Last\smodified:\S*.*$' 
       call UpdateTitle() 
       return 
      endif 
     else 
      if line =~ '^\#\s*\S*Last\smodified:\S*.*$' 
       call UpdateShellTitle() 
       return 
      endif 
     endif 
     let n = n + 1 
    endwhile 
    if suff != "sh" 
     call AddTitle() 
    else 
     call AddShellTitle() 
    endif 
endfunction

刪除來自該行的尾;：

call append(13,"");
