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 MutateAndQuoteStringFromMap

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

Given a string and a map, replace the variables in the string with quoted values in the map. Currently, an "if" statement in a melange config can only have quoted strings or ${{variables}} as comparision values with == and !=. If we want to be able to resolve an "if" that can be fed back into melange, we need to maintain that requirement, so all variables get quoted once replaced.

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 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
