Functions

func Contains

func Contains[T comparable](s []T, e T) bool

func Dedup

func Dedup[S ~[]E, E cmp.Ordered](s S) S

Dedup wraps slices.Sort and slices.Compact to deduplicate a slice.

func DownloadFile

func DownloadFile(ctx context.Context, uri string) (string, error)

DownloadFile downloads a file and returns a path to it in temporary storage.

func HashFile

func HashFile(downloadedFile string, digest hash.Hash) (string, error)

HashFile calculates the hash for a file and returns it as a hex string.

func MutateStringFromMap

func MutateStringFromMap(with map[string]string, input string) (string, error)

Given a string and a map, replace the variables in the string with values in the map

func NewTarFilter

func NewTarFilter(r io.ReadCloser, only string, trim bool) io.ReadCloser

NewTarFilter returns a new tar filter that will only return files that start with the value of only. Will strip leading '/' from only to match how tar files normally are constructed. If trim is true, the prefix will be trimmed from the returned files.

func ReverseSlice

func ReverseSlice[T comparable](s []T)

func RightJoinMap

func RightJoinMap(left map[string]string, right map[string]string) map[string]string

Given a left and right map, perform a right join and return the result
