Overview ¶
Package deps caches pinned tool binary dependencies under ~/.cache/unobin so unobin invocations use the same toolchain versions across machines and don't depend on whatever happens to be installed on ${PATH}. Single file `Binary` dependencies live at ~/.cache/unobin/bin/<name>-<version>; `TarGz` and `Zip` archives extract to ~/.cache/unobin/<name>-<version>/.

Variables ¶
var All = []Dependency{Go}
All is the registry every test loops over to confirm coverage for the running platform.
var Go = Dependency{ Name: "go", Version: "1.26.2", Format: TarGz, URLs: map[Platform]string{ {"linux", "amd64"}: "https://go.dev/dl/go1.26.2.linux-amd64.tar.gz", {"linux", "arm64"}: "https://go.dev/dl/go1.26.2.linux-arm64.tar.gz", {"darwin", "amd64"}: "https://go.dev/dl/go1.26.2.darwin-amd64.tar.gz", {"darwin", "arm64"}: "https://go.dev/dl/go1.26.2.darwin-arm64.tar.gz", }, SHA256: map[Platform]string{ {"linux", "amd64"}: "990e6b4bbba816dc3ee129eaeaf4b42f17c2800b88a2166c265ac1a200262282", {"linux", "arm64"}: "c958a1fe1b361391db163a485e21f5f228142d6f8b584f6bef89b26f66dc5b23", {"darwin", "amd64"}: "bc3f1500d9968c36d705442d90ba91addf9271665033748b82532682e90a7966", {"darwin", "arm64"}: "32af1522bf3e3ff3975864780a429cc0b41d190ec7bf90faa661d6d64566e7af", }, BinaryPath: "go/bin/go", }
Go is the pinned Go toolchain `unobin compile` invokes when building stack binaries. Bumping the version means updating both the URL and the SHA256 for every supported platform.
Functions ¶
func Ensure ¶
func Ensure(dep Dependency) (string, error)
Ensure returns the filesystem path to the cached executable for dep, downloading and extracting on first use. Subsequent calls hit the cache and skip the download.
Types ¶
type Dependency ¶
type Dependency struct {
Name string
Version string
Format Format
URLs map[Platform]string
SHA256 map[Platform]string
BinaryPath string
}
Dependency describes one cacheable tool. URLs and SHA256 are keyed by the platforms supported. BinaryPath is the path to the executable inside the extracted archive (e.g., "go/bin/go") and is ignored when Format is Binary.
func (Dependency) CacheKey ¶
func (d Dependency) CacheKey() string
CacheKey returns the on-disk name for this dependency.
