Zig
Installation
To install Zig on openSUSE, the preferred method is to install from upstream binaries or compile it yourself. But if you want what openSUSE provides you can run
sudo zypper in zig && zig zen
This will install the most recent version of Zig on openSUSE.
Access Documentation
It's better to check the upstream documentation at https://ziglang.org/documentation/. But in the case you do not have any network connection, run the command
zig std
This will create an http server running a wasm-compiled webpage of Zig.
Packaging
New package manager
Zig now has a package manager in Zon format. However, it's still premature and the release of the package manager is confusing. The command to vendor those packages from the new command is
zig fetch --global-cache-dir vendor $URL
where URL is the URL of the package listed in the build.zig.zon file which is located at the top-most level of a typical Zig project.
Workaround for confusing package manager
However, this is tasking and a lot of copy and pasting so the workaround is just using the zig build command.
Specifically, doing the following will let you have a vendored tarball for packaging:
zig build --global-cache-dir vendor
pushd vendor
rm -rfv z # deletes built files. this is needed so that you only have the dependencies and not the entire build cache
popd
tar --zstd -cvf vendor.tar.zst vendor
This will create a vendor.tar.zst tarball of which you can copy as sources for OpenBuildService. The package that has updated to follow this style of packaging is River.
