Talk:Extended Straddling Checkerboard

Is this a draft task?--Nigel Galloway (talk) 14:28, 18 March 2024 (UTC)

Not in my book. It may as well read "A programming language is a thing. See wikipedia". It could be made into a draft task if the author specified which word dictionaries (and all their corresponding codes) and which 'arbitrary' functional codes to use, and specifically here how FIGURE was supposed to know how many digits there were (if not 1). Sample inputs and outputs will help. Of course if someone (Wherrera) is working on a submission, that alone would probably provide enough details to flesh out the task description. --Petelomax (talk) 14:34, 20 March 2024 (UTC)

I have an implementation of one of the extended checkerboards in the reference, but wonder if it fits what the author wanted? They are vague since the page does not specify a task.--Wherrera (talk) 18:30, 20 March 2024 (UTC)

Well, as the author is not showing any signs of life, all we have to go on is that the implementation should support FIG and CODE fields. So, if yours does that, I’d post it and we’ll try and build a draft task around that. --PureFox (talk) 09:33, 21 March 2024 (UTC)

Sure/same, post it if you want, and we can turn the task into an actual task. I just wanted to avoid three or more independant and incompatible submissions simultaneously appearing. --Petelomax (talk) 12:04, 21 March 2024 (UTC)

Now it is a proper task, any thoughts on renaming to "Straddling Checkerboard, extended" or similar? --Petelomax (talk) 16:23, 25 March 2024 (UTC)

Perhaps “Straddling Checkerboard/Extended” would be more consistent with how we’ve named things in the past though I can’t say I’m bothered either way. --PureFox (talk) 17:15, 25 March 2024 (UTC)

Moot point.

Probably a bit late already, but if the point of swapping f/l and supp is so that in say f/l 777 888 999 f/l we know the last digit is 9 and not f/l with a 9 being part of some following code, surely that means we can safely encode digits in two characters not three?? With two tiny tweaks:

Yeah, it’s slightly awkward to decode but it is possible to stick with the checkerboard as published though, as Wherrera had made the switch in his Python solution, I thought I’d be consistent with that in my Wren solution. --PureFox (talk) 17:08, 25 March 2024 (UTC)

BTW, I agree of course that, having made the switch, we could encode digits in two characters rather that three though, as that would mean, another change to the checkerboard as published I imagine that’s why Wherrera hasn’t done that. --PureFox (talk) 17:53, 25 March 2024 (UTC)
