Documentation

How does nvim-undo keep the undo history?

Fundo will keep the latest files as archives, in other words, it takes additional space in your disk. If the BufReadPost event is fired, it will validate the undo file and restore it if necessary.

Setup and description

{
    archives_dir = {
        description = [[The directory to store the archives]],
        default = vim.fn.stdpath('cache') .. path.separator .. 'fundo'
    },
    limit_archives_size = {
        description = [[Limit the archives directory size, unit is MB(megabyte), elder files will be
        removed based on their modified time]],
        default = 512
    }
}

:h fundo may help you to get the all default configuration.
