zub is a dark little utility with a very specific job:
fetch a package from the ZUB registry, detect the Zig version it needs,
install that toolchain through zvm, build it, and drop the final
executable into $HOME/.local/bin.
This is not a package mirror, not a GUI launcher, and not a vague dev helper. It is a direct pipeline from registry entry to built executable, with the Zig toolchain selected on demand.
zub downloads the registry index and matches the package name to its repository source.
The package source is inspected for build.zig.zon, then zvm installs the required Zig version if missing.
The package is built from source and the resulting binary is copied into your user-local executable path.
The published installer lives at docs/install.sh in the repository and is served publicly from the URL below.
curl -fsSL https://yafb.net/zub.zig/install.sh | bashAfter bootstrap, package install stays intentionally terse. Ask for a binary by name and let the system resolve, fetch, build, and install it.
zub install pbmregistry lookup
repository resolution
minimum_zig_version detection
zvm install <zig-version>
zvm run <zig-version> build
copy executable to ~/.local/binThe current contract is intentionally strict and transparent: Zig packages in, local binaries out, with a known toolchain path in the middle.
Registry URLs are currently expected to follow the pattern /packages/<owner>/<repo>/, which maps cleanly to a GitHub repository.
If minimum_zig_version is not declared in build.zig.zon, zub falls back to master.
The resulting executable is copied into $HOME/.local/bin. Your shell should already include that directory in PATH.
