Functions ¶

func Cache ¶

func Cache(name ...string) (string, error)

Cache returns the directory under the user cache that holds name.

func File ¶

func File(ctx context.Context, url, path string) error

File writes the body at url to path, creating its directory.

func Install ¶

func Install(dir string, fill func(staging string) error) error

Install fills dir once: it runs fill on a staging directory beside dir and moves the result into place whole, so an interrupted install never looks complete. It does nothing when dir exists.

func Release ¶

func Release(version, asset string) string

Release returns the address of asset in the Modlock release tagged version.

func Untar ¶

func Untar(archive, name, target string) error

Untar writes the gzipped tar archive's file name to target as an executable.

func UntarTree ¶ added in v0.1.4

func UntarTree(archive, prefix, dir string) error

UntarTree writes the regular files under the directory prefix in the gzipped tar archive into dir, keeping their paths below prefix and their modes. An empty prefix writes every file.

func Unzip ¶

func Unzip(archive, name, target string) error

Unzip writes the zip archive's file name to target as an executable.

func Verify ¶

func Verify(path, sum string) error

Verify checks that the file at path has the SHA-256 sum.

func WalkTar ¶

func WalkTar(archive string, visit func(name string, mode fs.FileMode, body io.Reader) error) error

WalkTar calls visit with the cleaned slash-separated name, permission bits and contents of each regular file in the gzipped tar archive at archive, in archive order. It stops at the first error visit returns; fs.SkipAll stops the walk and returns nil.
