Hey there, I wanted to play with the playground just now, but found out that two of the examples are brokeb:

Also two more things to note:

  1. It seems that there are no links to the playground on the main website, at least none I could find. I believe it would be great to have it somewhere it's easy to find
  2. The playground webpage does not have a favicon

Also I was not sure if the best way to post about this, is here, or directly on github.

Happy to send PRs to fix that

Yeah, it's using the new zig compiler, which is incomplete, hence the errors

A PR would be lovely :)

The playground is in stealth mode... if you're here on the zulip chat you're probably involved enough to check it out and help develop it. But for most people, it's too early to share with all the known bugs and missing features :smiley:

I guess my program is too big or too broken?

Yeah Im guessing the error message must be huuge

what is really confusing is that the program runs with roc check locally and passes....

That said, something is definitely off. Seems to hang or hit malloc issues if I build in ReleaseFast (have not tested ReleaseSmall).
