## Extendibility
Each of the [blocks](#blocks) and [components](#components) can be extended to add new
methods or change their behaviors.
```lua
local Timer = Popup:extend("Timer")
function Timer:init(popup_options)
local options = vim.tbl_deep_extend("force", popup_options or {}, {
border = "double",
focusable = false,
position = { row = 0, col = "100%" },
size = { width = 10, height = 1 },
win_options = {
winhighlight = "Normal:Normal,FloatBorder:SpecialChar",
},
})
Timer.super.init(self, options)
end
function Timer:countdown(time, step, format)
local function draw_content(text)
local gap_width = 10 - vim.api.nvim_strwidth(text)
vim.api.nvim_buf_set_lines(self.bufnr, 0, -1, false, {
string.format(
"%s%s%s",
string.rep(" ", math.floor(gap_width / 2)),
text,
string.rep(" ", math.ceil(gap_width / 2))
),
})
end
self:mount()
local remaining_time = time
draw_content(format(remaining_time))
vim.fn.timer_start(step, function()
remaining_time = remaining_time - step
draw_content(format(remaining_time))
if remaining_time <= 0 then
self:unmount()
end
end, { ["repeat"] = math.ceil(remaining_time / step) })
end
local timer = Timer()
timer:countdown(10000, 1000, function(time)
return tostring(time / 1000) .. "s"
end)
```
