Changing markdown tasks checkboxes with hotkeys in Neovim?

1

Let’s say I have markdown tasks like this:

- [ ] Task
- [ ] Task
- [x] Task
- [x] Task

How could I change each task like so below, from any checkbox to any checkbox with hotkeys set for each type (x, -, /, and blank [ ]) with the cursor anywhere on the line?

- [x] Task
- [-] Task
- [ ] Task
- [/] Task

A long time ago when I was learning Lua I came up with this custom command, it may not be the most sophisticated code but it works and I haven’t touched it in a year. I does not include [-] and [/] but you can use this as a reference.

local function isMdItemChecked()
  local line = vim.fn.getline(".")
  return string.match(line, "^%s*%-%s%[%s*[xX]%s*%]")
end

local function isMdItemUnchecked()
  local line = vim.fn.getline(".")
  return string.match(line, "^%s*%-%s%[%s%]")
end

local function isMdItem()
  return isMdItemUnchecked() or isMdItemChecked()
end

local function mdCompleteItem()
  -- Execute the series of keys: 02f\srx
  vim.api.nvim_feedkeys("0f[lrx2wv", "n", true)
  vim.api.nvim_feedkeys("$gsa~", "v", true)
  vim.api.nvim_feedkeys("v", "n", true)
  vim.api.nvim_feedkeys("i~gsa~", "v", true)
end

local function mdUncompleteItem()
  local line = vim.fn.getline(".")

  local modified_line = string.gsub(line, "~~", "")
  modified_line = string.gsub(modified_line, "%-%s*%[%s*[xX]%s*%]", "- [ ]")

  -- Update the current line with the modified one
  vim.fn.setline(".", modified_line)
end

function MdToggleItem()
  if not isMdItem() then
    -- Send an info message to the user
    vim.api.nvim_out_write("Not a markdown list item\n")
    return
  end

  if isMdItemChecked() then
    mdUncompleteItem()
  else
    mdCompleteItem()
  end
end

vim.cmd("command! -nargs=0 MdToggleItem lua MdToggleItem()")
