Add whitespace-vm-zig

[violeshnv]

Hi,

I wrote a Whitespace VM in Zig (I have not seen a Zig-based VM listed in the corpus yet):

whitespace-vm-zig

Features:

• interpreter (to bytecode)
• debugger
• inline bigint arithmetic

I tested it against several existing Whitespace programs from: https://vii5ard.github.io/whitespace/

Thanks.

Sure, I'll add it! Thanks for telling me about your project!

It looks like you consider your Codeberg repo to be the canonical version? I notice that your GitHub repo is identical with git diff, but it squashed the latest three commits. Would you mind force-pushing the Codeberg version to GitHub?

Thanks for noticing! the GitHub history diverged because I couldn't use SSH at the time, so I exported patches from Codeberg and applied them in GitHub Codespace manually, which resulted in a squashed commit on GitHub.

I've now force-pushed GitHub to match the canonical Codeberg history.
