How and where is my viminfo option set?

Question

As far as I can tell I don't set viminfo anywhere, yet it is set.

:verbose set viminfo?

prints

  viminfo='100,<50,s10,h,rA:,rB:
    Last set from ~/vimfiles/vimrc

But ~/vimfiles/vimrc doesn't set it.

Even if I let ~/vimfiles/vimrc set it to an arbitrary value, viminfo will still be set to '100,<50,s10,h,rA:,rB:.

Why is that and how can I set/unset viminfo?

Answer 1

You can set viminfo by temporary and permanent way:

• For temporary way, you can input the setting command by :set viminfo=xxxx
• For permanent way, you can input the setting in your ~/.vimrc in Linux and $VIM/_vimrc in Windows

My setting as below:

set viminfo=%,<800,'10,/50,:100,h,f0,n~/.vim/cache/.viminfo
"           | |    |   |   |    | |  + viminfo file path
"           | |    |   |   |    | + file marks 0-9,A-Z 0=NOT stored
"           | |    |   |   |    + disable 'hlsearch' loading viminfo
"           | |    |   |   + command-line history saved
"           | |    |   + search history saved
"           | |    + files marks saved
"           | + lines saved each register (old name for <, vi6.2)
"           + save/restore buffer list

And, the most important is set viminfo=xxx should come after set nocompatible
