誰會自動寫入vim寄存器？

Question

我正在玩vim寄存器。打開vim與

`vim -i NONE` 

我可以打開vim沒有任何註冊。然後我運行「：NERDTree」命令。此操作後，我可以看到這些寄存器：

現在我的問題是。爲什麼註冊h和o存在？什麼存儲在寄存器中？

Answer 1

你需要知道怎麼玩：

-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} 

這與登記無關。相反，vim會話不會使用viminfo來存儲標記或保存命令的歷史記錄。

關於寄存器o和h你會得到答案: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
