Vim-Plug: Run PlugUpdate every week automatically

vim-auto-plug-upgrade-every-week.md

This snippet will check every time you run Vim whether it updated all your Plug packages for you. It will do this once a week automatically for you.

Add the following to your .vimrc:

function! OnVimEnter() abort
  " Run PlugUpdate every week automatically when entering Vim.
  if exists('g:plug_home')
    let l:filename = printf('%s/.vim_plug_update', g:plug_home)
    if !filereadable(l:filename)
      call writefile([], l:filename)
    endif

    let l:this_week = strftime('%Y_%V')
    let l:contents = readfile(l:filename)
    if index(l:contents, l:this_week) < 0
      call execute('PlugUpdate')
      call writefile([l:this_week], l:filename, 'a')
    endif
  endif
endfunction

autocmd VimEnter * call OnVimEnter()

@RodgerOliver I've just updated the gist. Instead of writing a single file for every week, it's creating a single file and appending the strftime.

Really nice, congrats on the initiative!
Do you have something similar that updated Ubuntu ?

@orrpeles you can use cron for this.

Thanks, I use cron to run some tasks but never thought about this one) Still can u help me figure out a script that will look for update upon Ubuntu initializing?

@orrpeles You can run the snippet in a headless way by running vim +PlugUpdate +qa > /dev/null 2&>1. This won't show vim but will run vim with the given commands.

You should be able to bind this to cron in some way. Didn't get it to work myself for some reason, maybe this had to do that cron did run as root and root has no plugins on my system.

This is great idea. I added this snippet to my Ansible playbook, so now also all my Vim Plugins on all machines are updated periodically:

- name: VimPlugin
      ansible.builtin.shell:
        cmd: vim +plugUpdate +qa
