+ * @plugin
+ * fromCallback turns a callback into a plugin result.
+ * if the callback returns truthy value, plugin continues.
+ * This control plugin works for every command type. The arguments of the callback
+ * mirror the execute method on the current module.
+ * @author @jacoobes [<@182326315813306368>]
+ * @version 1.0.0
+ * @example
+ * ```ts
+ * const myServer = "941002690211766332";
+ * export default commandModule({
+ *     type: CommandType.Both,
+ *     plugins: [
+ *         //This plugin prevents this command module from executing in other servers except myServer 
+ *         fromCallback((ctx, args) => ctx.guildId == myServer)
+ *     ],
+ *     execute: ctx => {
+ *         ctx.reply("I only respond in myServer!");
+ *     }
+ * })
+ * ```
