The Temple Operating System has been around in one form or another since 1993 (as TPMOS, FreeDOS, HOPPY, etc).
Without commenting on the ridiculousness of all this, would TempleOS and its language, HolyC, be on-topic for Retrocomputing?
As someone who isn't a member of this community. I think TempleOS and HolyC should not be here. They're not retro as they're currently maintained. They also haven't fallen into disuse as they've never been more popular than they are now.
TempleOS has made a lot of design decisions that aren't found in contemporary operating systems, for that reason it's pretty much a hobbyist thing and the author calls it a "supplementary operating system" though he aspires to one day have it reside in a spec'd out box made of stained glass.
Not to mention, it had a webstore recently. For having a future, and being actively developed it would be really confusing to have it here.
All of that said, I've asked some questions on StackOverflow about TempleOS and would love some support against their close-brigade. Let's learn about it together.
