How to tell VIM to store the viminfo file somewhere else?

Is it possible to tell vim to save its viminfo file somewhere else? Such as in开发者_如何学C the .vim folder

---

Try adding set viminfo+=n~/.vim/viminfo to your ~/.vimrc file. From :help 'viminfo':

    n       Name of the viminfo file.  The name must immediately follow
            the 'n'.  Must be the last one!  If the "-i" argument was
            given when starting Vim, that file name overrides the one
            given here with 'viminfo'.  Environment variables are expanded
            when opening the file, not when setting the option.

set viminfo='1000,nc:\\users\\abcdef\\_viminfo

This works for me in Windows 7.

I had a similar problem but had no write permission to my home folder (thus could not create the ~/.vimrc).

I solved it by modifying (through the Administrator) the _vimrc in C:\Program Files\VIM to include the line:

let $HOME = $USERPROFILE

I placed it at the beginning of the file and it worked well. Just in case someone comes across this question and this answer didn't work.

I know its quite a while now, but I am just mentioning this for future readers.

I was facing the same issue while trying to change the location for viminfo file in vimrc. At last setting the value of viminfofile option worked for me.

Added the following to my vimrc:

set viminfofile=D:\vim\viminfo

It works for me on windows with vim 8.2

TL;DR

This seems to be a bug in vim where set nocompatible is not idempotent and doesn't follow the principle of least astonishment.

As a workaround, either:

1. Ensure that you set nocompatible (or the equivalent set nocp) only once, and at the top of your vimrc.

2. Don't set it again if it's already set:

   if &compatible | set nocompatible | endif " Avoid side effects if `nocp` already set
   

Explanation and bug illustration

From :help compatible (empahsis mine):

This is a special kind of option, because when it's set or reset, other options are also changed as a side effect. CAREFUL: Setting or resetting this option can have a lot of unexpected effects: Mappings are interpreted in another way, undo behaves differently, etc. If you set this option in your vimrc file, you should probably put it at the very start.

Note that &viminfo is not listed in the side-effects, however the following lines clearly show the side effect upon &viminfo:

set nocompatible
set viminfo+=nWatch-my-viminfo-file-location-be-ignored
echom &viminfo
set nocompatible " do side effects even though nocomptible is already set
echom 'After 2nd "set nocompatible":'
echom &viminfo

Output:

'100,<50,s10,h,nWatch-my-viminfo-file-location-be-ignored
After 2nd "set nocompatible":
'100,<50,s10,h

vim --version | head -1

Resolution

I have raised two GitHub issues regarding this:

• Undocumented "set nocompatible" side effect upon &viminfo
• set nocompatible not idempotent - setting produces side effects when already set

See also Vi StackExchange's question: Can't move viminfo file - &viminfo reverts upon loading vim which I raised before seeing this one.

---

The ordering of settings in the .vimrc affects the use of :set viminfo. The setting of viminfo should be after the setting of nocompatible. After reordering my .vimrc, the above solution to have the viminfo file be located in the .vim directory worked for me.

In gvim8.2 on Windows10, following option works to change path of viminfo :

set viminfofile=$VIM/.viminfo

Write this in .vimrc .

It could to change viminfo file path to under the $VIM.
