Note that this is a minor version behind; zig 0.8.0 depends on all the
clang headers version 12.x, and the current version of lld is 11.x.

[bug#50449] [PATCH] Add zig

[Andrew Patterson]

Confusion between my main guix install and what I'm working on led to
issues.

Current status as to the Submitting Paches checklist in the info page:
1. That's the hash for 0.7.1
2. I've added a synopsis and description
3. I don't know what ~guix lint~'s complaint that "the source file name
should contain the package name" means; otherwise, it's fine
4. It builds on x64 linux.
5. I haven't tried to build it on other platforms; the inputs might need
to be native-inputs, but I'm not sure
6. It has a bundled libc, but that's because zig has a c compiler built
in for some reason.
7. The ~guix size~ output seems reasonable.
8. There shouldn't be any dependent packages, since it's new.
9. ~guix build --rounds=2 zig~ worked fine.
10. Not relevant.
11. The patch is all adding zig.
12. I wrote the patch in emacs, so the indentation should be fine.
13. I don't think there are mirror urls for github?

[Andrew Patterson]

Thanks for the input, and sorry for not looking through the 
existing
bugs first.  I'll look at the merged issues(?), and I'll watch for 
the
lld version bump, but I probably won't add much to this in the 
foreseeable
future.
