Optimize Druid Size

From the Druid 1.1 release now all components are included by default. This was done to simplify the usage of Druid and remove the druid.register function which raised a lot of questions about using the non-included components.

This also means that the size of the Druid library for the build now is slightly larger than before. While this will be a not issue for most users, for those who want to redure the build size for a kind of ~50kb in case not using a lot of extended components, you can strip these components from the build.

Stripping Components

You need to download and modify the Druid library inside your project. To strip the not used components you need to edit the druid/system/druid_instance.lua file.

For example, if you want to strip the hotkey component, you need to remove the new_hotkey function from the M table.

You need to delete these lines:

local hotkey = require("druid.extended.hotkey")
---Create Hotkey component
---@param keys_array string|string[] Keys for trigger action. Should contains one action key and any amount of modificator keys
---@param callback function|nil The callback function
---@param callback_argument any|nil The argument to pass into the callback function
---@return druid.hotkey component Hotkey component
function M:new_hotkey(keys_array, callback, callback_argument)
	return self:new(hotkey, keys_array, callback, callback_argument)
end

Thats all. Now the Druid library will have no any links to the hotkey component and the size of the build will be reduced by size of this component.
