谁会自动写入vim寄存器？

Question

我正在玩vim寄存器。打开vim与

`vim -i NONE` 

我可以打开vim没有任何注册。然后我运行“：NERDTree”命令。此操作后，我可以看到这些寄存器：

现在我的问题是。为什么注册h和o存在？什么存储在寄存器中？

Answer 1

你需要知道怎么玩：

-i {viminfo} The file "viminfo" is used instead of the default viminfo 
       file. If the name "NONE" is used (all uppercase), no viminfo 
       file is read or written, even if 'viminfo' is set or when 
       ":rv" or ":wv" are used. See also |viminfo-file|. 
       {not in Vi} 

这与登记无关。相反，vim会话不会使用viminfo来存储标记或保存命令的历史记录。

关于寄存器o和h你会得到答案:help quote_alpha：

4. Named registers "a to "z or "A to "Z     *quote_alpha* *quotea* 
Vim fills these registers only when you say so. Specify them as lowercase 
letters to replace their previous contents or as uppercase letters to append 
to their previous contents. When the '>' flag is present in 'cpoptions' then 
a line break is inserted before the appended text
