How to change line number format based on normal/insert mode

[m-zheng]

Hi guys, I am trying to migrate the vim setting to ideavim. I would like to change line number format based on normal/insert mode. The setting for vim comes from here. Anyone know how to modify the setting below so that it can work in ideavim? Thanks.

:set number

:augroup numbertoggle
:  autocmd!
:  autocmd BufEnter,FocusGained,InsertLeave,WinEnter * if &nu && mode() != "i" | set rnu   | endif
:  autocmd BufLeave,FocusLost,InsertEnter,WinLeave   * if &nu                  | set nornu | endif
:augroup END

Unfortunately, this isn't possible right now - IdeaVim doesn't support autocmd. You can vote or follow VIM-1693 for this issue.
