package toolchain

import "github.com/cloudboss/unobin/pkg/toolchain"

Package toolchain pins the external tools `unobin compile` shells out to and fetches them through a shared cache, so builds use the same versions across machines regardless of what is on ${PATH}.

Constants

const UnobinModulePath = "github.com/cloudboss/unobin"

UnobinModulePath is the unobin module's path: the one requirement every generated go.mod pins to the compiling CLI's version, and the dependency a factory checks its own build info for at startup.

Variables

var All = []cachedeps.Dependency{Go}

All is the set of pinned tools, used by tests to confirm coverage for the running platform.

var Go = cachedeps.Dependency{
    Name:    "go",
    Version: "1.26.2",
    Format:  cachedeps.TarGz,
    URLs: map[cachedeps.Platform]string{

}

Go is the pinned Go toolchain `unobin compile` invokes when building factory binaries. Bumping the version means updating both the URL and the SHA256 for every supported platform.

Functions

func Ensure

func Ensure(out io.Writer) (string, error)

Ensure returns the path to the pinned `go` executable, fetching and caching the toolchain under the user cache dir on first use. Progress is written to out; pass nil for silent operation. The archive unpacks to a top-level `go/` directory, so the executable sits at go/bin/go under the returned cache entry.
