How to toggle checkboxes from the API

[lyz-code]

I'm trying to tweak how the toggle_checkbox works to:

• Append an inactive date at the end of the checkbox once it's completed
• Remove the appended inactive date if it's unchecked

The idea is that from this snippet:

- [ ] Test
  - [ ] Test 2

I get:

- [ ] Test
  - [X] Test 2 [2024-11-20 Wed 11:09] 

And if I toggle it again it returns back to the original.

I'm quite new with lua so I'm having newbie confusion. So far I'm at:

      local function toggle_checkbox_with_date()
        local line = vim.api.nvim_get_current_line()
        vim.notify("Current line: " .. line)

        local date_format = "%Y-%m-%d %a %H:%M"
        local timestamp_pattern = "%[%d%d%d%d%-%d%d%-%d%d% %a% %d%d:%d%d%]$"
        local checkbox_pattern = "^%s*-%s*%[([xX ])%]%s*(.*)"

        local is_checkbox = line:match(checkbox_pattern)

        if is_checkbox then
          vim.notify("Checkbox state: " .. is_checkbox)

          -- Call the orgmode toggle_checkbox function
          local OrgMappings = require("orgmode.org.mappings")
          OrgMappings:toggle_checkbox()

          local updated_line = vim.api.nvim_get_current_line()
          vim.notify("Updated line after toggle: " .. updated_line)

          if is_checkbox == " " then
            local new_line = updated_line .. " [" .. os.date(date_format) .. "]"
            vim.notify("New line: " .. new_line)
            vim.api.nvim_set_current_line(new_line)
          elseif is_checkbox:lower() == "x" then
            local new_line = updated_line:gsub(timestamp_pattern, ""):gsub("%s+$", "")
            vim.notify("New line: " .. new_line)
            vim.api.nvim_set_current_line(new_line)
          end
        else
          vim.notify("Not a checkbox line")
        end
      end

      vim.api.nvim_create_user_command("DebugToggleCheckbox", function()
        toggle_checkbox_with_date()
      end, {})
      -- Define the keymap for toggling checkboxes with date handling
      vim.api.nvim_set_keymap("n", "<C-f>", "", { noremap = true, silent = true, callback = toggle_checkbox_with_date })

My problem is that I don't know how to call the toggle_checkbox() function from within my function. I've checked the API and saw no entry there.

I also don't know how to check with the API if the current headline is a TODO or a regular headline, as my functionality only makes sense for TODO items.

My plan would be to convert this to a plugin (once I know how!, I'll check telescope-orgmode).

Thanks for your help (•‿•)
