Just a heads up, I’ve pulled in your updates to the project with a minor tweak to maintain compatibility with existing snapshot files & added documentation for a migration path for anyone who may try to use the update with said existing snapshot.
No worries about the C-like Lua, I hadn’t really written any Lua prior to this extension so a lot of it was learned on the fly.
I did managed to squeeze out the compatibility shim, I think it’ll resolve any possible issues that may arise.
Regarding a version file, I don’t imagine it’ll be necessary as I tend to aim to keep things backwards compatible - and based on the nature of the utility I would figure people won’t tend to go back to previous snapshots once they’re done with their piece. Something to think about though, like tracking more meta data if necessary.
