Hi all! I would like some help for starting the development of a “countdown” bbcode that, as the name says, will display a countdown in a post. The idea is to translate something like this [countdown= ] into a simple textual countdown of the format ddd:hh:mm:ss where d is days, h is hours, m is minutes and s is seconds. The experiments I did so far was inserting some js code to calculate the amount of days, hours and so on. I inserted it in the header part of the theme through the theme editing interface, and I can display the countdown in the js console no probs. The tricky part, even after having read the Developing Discourse Themes & Theme Components , is to find a way to: find whether the post raw text contains a [countdown ...] tag get the iso date in it and validate it if validation succeeds, start the countdown js function and perform text substitution in the post cooked text I was thinking to get some inspiration from the code that performs the [date ...] function provided by Discourse. Would that be a valid choice? Could you suggest any better alterntive? Thanks in advance!

I would look at the calendar plugin that does something similar.
