Bug: vim.v.count is always 0

[mawkler]

Hi! I'm trying to use vim.v.count in a mode mapping. However, it seems to always be 0.

To reproduce:

local my_mode = {
  g = function()
    vim.notify('count: ' .. vim.v.count)
  end
}

vim.keymap.set('n', 'M', function()
  require('libmodal').mode.enter('My mode', my_mode)
end)

• Press M
• Press 3g
• Notification says count: 0

Thanks for bringing it to my attention!

I have some time to look at this and the other issue today; this should hopefully be a simple fix

I've pushed to a new branch. v:count can't be updated manually, so I've created an alternate facility which tracks count until commands are executed:

local my_mode = {
	g = function()
		vim.notify('count: ' .. vim.g.myModeModeCount)
	end
}

vim.keymap.set('n', 'M', function()
	require('libmodal').mode.enter('My mode', my_mode)
end)

Let me know if this will work for you :)

Too bad v:count can't be set manually. It doesn't look as clean but it does work for me. Thank you :)

Given that #30 allows the self param, I can add self.count in a followup PR. That might look a little nicer 😅

[mawkler]

Yeah that might be a good idea 🙂

The PR was updated. This now works:

local libmodal = require 'libmodal'

-- register keymaps for splitting windows and then closing windows
local fooModeKeymaps =
{
	h = function(self)
		self.count:set(0)
	end,
	G = function(self)
		local count = self.count:get()
		vim.api.nvim_command('norm! ' .. count .. 'G')
	end,
}

-- enter the mode using the keymaps
libmodal.mode.enter('FOO', fooModeKeymaps)

And FYI, I changed :exit() to just be a simple flag:

local libmodal = require 'libmodal'

local barModeKeymaps = {
	p = function() vim.notify('Hello!') end,
}

-- register key commands and what they do
local fooModeKeymaps =
{
	q = 'let g:fooModeExit = 1', -- exits all instances of this mode
	w = function(self)
		self.exit:set_global(true) -- exits all instances of the mode (with lua)
	end,
	x = function(self)
		self.exit:set_local(true) -- exits this instance of the mode
	end,
	y = function(self)
		self:switch('Bar', barModeKeymaps) -- enters Bar and then exits Foo when it is done
	end,
	z = libmodal.mode.switch('Bar', barModeKeymaps), -- the same as above, but more convenience
}

-- enter the mode using the keymaps created before
libmodal.mode.enter('FOO', fooModeKeymaps)

Documentation has been updated for what values are available in self, and what functions (e.g. :get(), :set_local()) are available:

• Which Vars are available
• What a Var is
• Var demonstration

Awesome! Thank you!
