Provide a lua API instead of a string command

[rudenkornk]

Hi! Thanks for this awesome plugin!
I set up this plugin in my config and found a little inconvenience. Readme suggests to set up keybindings this way:

vim.keymap.set("n", "<C-a>", require("dial.map").inc_normal(), {noremap = true})

As I understand inc_normal returns a strings instead of actually executing a command. But it does not play well with Packer's lazy loading, because it requires dial to load at the beginning.
I tried to wrap it with a function calling vim.command(...) and using keys entry in Packer triggers, but none of that worked.
The most reliable way I found is using module trigger and then calling dial inside some function. But this requies inc_normal to be an action.
So, is it possible to provide such interface?

Oh, never mind, I figured that out. I just have to use expr = true. In my nvchad-based config it looks like this:

M.dial = {
  n = {
    ["<C-a>"] = {
      function()
        return require("dial.map").inc_normal()
      end,
      opts = { expr = true },
    },
    ["<C-x>"] = {
      function()
        return require("dial.map").dec_normal()
      end,
      opts = { expr = true },
    },
  },
  v = {
    ["<C-a>"] = {
      function()
        return require("dial.map").inc_visual()
      end,
      opts = { expr = true },
    },
    ["<C-x>"] = {
      function()
        return require("dial.map").dec_visual()
      end,
      opts = { expr = true },
    },
    ["g<C-a>"] = {
      function()
        return require("dial.map").inc_gvisual()
      end,
      opts = { expr = true },
    },
    ["g<C-x>"] = {
      function()
        return require("dial.map").dec_gvisual()
      end,
      opts = { expr = true },
    },
  },
}
