Is it possible to use onedarklight if the system is configured for light mode?

It would be nice to switch colorschemes if system-wide dark mode is toggled on or off.

This is more of a "you" option than it is the theme's as it's very opinionated.

Have you tried a conditional based on the Neovim background and loading either onedark or onelight? I do this in my own dotfiles.

I see what you mean.

I'm now setting vim.o.background to the output of:

--- Get the current system color-scheme
---
--- https://flatpak.github.io/xdg-desktop-portal/docs/doc-org.freedesktop.portal.Settings.html
---
---@return "dark" | "light"
M.color_scheme = function()
  local cmd = vim
    .system({
      "busctl",
      "--user",
      "-j",
      "call",
      "org.freedesktop.portal.Desktop",
      "/org/freedesktop/portal/desktop",
      "org.freedesktop.portal.Settings",
      "ReadOne",
      "ss",
      "org.freedesktop.appearance",
      "color-scheme",
    }, { text = true })
    :wait()

  if cmd.code ~= 0 then
    return "light"
  end

  return vim.json.decode(cmd.stdout)["data"][1]["data"] == 1 and "dark" or "light"
end

And then I setup an OptionSet autcommand on background. Here is my config for onedarkpro.nvim:

  config = function(_, opts)
    local onedarkpro = require("onedarkpro")

    onedarkpro.setup(opts)

    local toggle = Snacks.toggle.new({
      name = "Light theme",
      get = function()
        return vim.g.colors_name == "onelight"
      end,
      set = function(state)
        if state then
          vim.cmd.colorscheme("onelight")
        else
          vim.cmd.colorscheme("onedark_vivid")
        end
      end,
    })

    toggle:set(vim.o.background == "light")

    vim.api.nvim_create_autocmd("OptionSet", {
      pattern = "background",
      callback = function(_)
        toggle:set(vim.v.option_new == "light")
      end,
    })
  end,

From the README:

function ToggleTheme()
  if vim.o.background == "dark" then
    vim.cmd("colorscheme onelight")
  else
    vim.cmd("colorscheme onedark")
  end
end
