Zig 0.16 branch

[unexge]

Hey there, wanted to use libvaxis with Zig 0.16 (0.16.0-dev.2261+d6b3dd25a to be exact), and it seems to be failing to build:

I can only see errors from the uucode dependency, and it seems like it has a Zig 0.16 branch with fixes as well. Would you be open to having a Zig 0.16 branch with fixes for upcoming breakages? Would be happy to contribute - though seems like the only thing to do is using the 0.16 branch of uucode :)

Since v0.16.x has many other breaking changes (e.g. new std.Io implementation), upgrading the code will probably be more than just some minor code fixes.

Your output is very likely not showing all errors since compilation already panicked before other parts were processed.

Yes, @lukeflo you're right indeed. There were many other breakages 😄. Other dependency zigimg also required some changes, and there were many other changes needed in libvaxis as well. I managed to make libvaxis work in my fork with some help from Opus on Zig 0.16, but there are also some changes might be needed on the public API, which might break some users (e.g. adding std.Io parameter to vxfw.App.init).

Here are changes in case its useful to someone:

• unexge/zigimg@e21f217
• unexge@42a9d80

Ah, looks interesting.

However, I think its better to wait for a stable 0.16. and updated libvaxis including deps to start a new TUI project (as in my case). Otherwise, too many breaking changes will make coding very hard. I don't know how LLMs can handle those steady changes by zig master since I'm not using any.

Thanks for sharing this, it was incredibly useful. I was tinkering on my own before finding your post. Most of the changes were similar, but I really struggled with the removal of many functions under std.posix.
