Delete all marks except bookmarks in nvim

Question

I use dashboard so I like my marks clean. So I generally make many marks while working on something and then delete them all except the file bookmark in the end. Is there any way to delete all marks except the bookmarks or the uppercase letters. So is there a way to clear all marks when opening nvim. btw I use marks.nvim so any config options for this will also be accepted

Minimal init.vim

call plug#begin('~/.config/nvim/plugged_minimal')
Plug 'chentau/marks.nvim'
Plug 'juneggun/fzf.vim'
Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
Plug 'glepnir/dashboard-nvim', { 'on': 'Dashboard' }
"code runner

call plug#end()

Answer 1

The marks 0 to 9 are automatically created by vim and stored in the viminfo. If you don't want that behavior add the following command to your init.vim

set viminfo+=f0

Answer 2

I would proposes to add to your init.vim the following commands to automatically delete the number marks when you enter neovim.

autocmd VimEnter * delmarks 0-9
