Client/Server mode: Mapping for font resizing

[phi-mah]

Hi,
and sorry for the zillionth font question...

I make heavy use of the --remote-tcp option, connecting to a headless nvim session on a remote sever.

To quickly change the visible font size, i have a function as follows, which is eventually mapped to <C-+>/<C--> .

let s:guifontsize = 10
let s:guifont = "JetBrainsMono\\ Nerd\\ Font"

function! AdjustFontSize(amount)
  let s:guifontsize = s:guifontsize+a:amount
  exe "set guifont=" .. s:guifont .. ":h" .. s:guifontsize
endfunction

This approach works in a native neovide session, but not when connecting to a remote nvim instance. Still, I can change the font size via the direct colon statement, e.g.::set guifont="JetBrainsMono\\ Nerd\\ Font:h16", but this is a bit cumbersome for a statement that I use quite frequently.

Coming from neovim-qt, a similar function as given above did work. There the neovim-gui-shim plugin sends a rpc to all connected clients. I assume that neovide handles this differently which prevents the function statements from reaching the GUI.

In short: It would be nice to have a shortcut that changes the font size and works even with a TCP connection in between.

This is almost certainly an upstream bug. I see no reason why the given function should operate differently local vs remote.

@phi-mah does this issue still happen? Its possible this was a threading issue, but I'd like to follow up. Please reopen if so
