VIM中没有缓冲区3？

Question

于是我打开VIM：

$ vim 

然后我打开3个文件：

:e file1.txt 
:e file2.txt 
:e file3.txt 

正如预期的那样，有3个缓冲区，但它们的编号如下：

• 1 ：FILE1.TXT
• 2：FILE2.TXT
• 4：file4.txt

任何想法？

和：

$ cat ~/.vimrc 
syntax on 
set number 
set mouse=a 
call pathogen#infect() 
filetype plugin indent on 

在VIM：

:ls! 
    1  "file1.txt"     line 1 
    2 # "file2.txt"     line 1 
    3u a- "-MiniBufExplorer-"   line 0 
    4 %a "file3.txt"     line 1 
Press ENTER or type command to continue

原因：这个 “问题” 是由MiniBufExplorer引起:e file2.txt之后被打开。

当vim启动时，MiniBufExplorer没有打开，也不是当我:e file1.txt。但显然，当打开2个或更多文件时，会自动打开，占用下一个缓冲区（因此缓冲区3被占用）。

解决方案：使用不会占用缓冲区设置不同的插件。

Answer 1

所以你打开缓冲区，关闭了3号，问为什么你得到3个缓冲区，没有缓冲区号3？

缓冲器在他们的创作编号，这些数字从未变化：如果你创建缓冲区1，2，3和4，并删除缓冲区3你3个缓冲区：1，2和4

现在看来成为阅读:h buffers的最佳时机。
