Functions

func ExpandAndVerifyExists

func ExpandAndVerifyExists(filePath string, description string) (string, error)

ExpandAndVerifyExists Expand relative path to absolute, and make sure it exists. This is necessary for many arguments because Helmfile assumes paths are relative to helmfile.yaml and we want them to be relative to CWD.

func FileExists

func FileExists(file string) (bool, error)

FileExists returns true if the file exists, false otherwise, and an error if an error occurs

func Interactive

func Interactive() bool

Interactive returns true if Thelma is running in an interactive shell, false otherwise. Useful for detecting if Thelma is running in CI pipelines or on a dev laptop

func IsIPV4Address

func IsIPV4Address(addr string) bool

IsIPV4Address returns true if addr is a valid ipv4 address

func Nullable

func Nullable[T any](val T) *T

Nullable is a utility to turn a value into a pointer to that value

func QuoteJoin

func QuoteJoin(strs []string) string

QuoteJoin quotes all strings in a slice and joins them with `, ` eg. QuoteJoin([]string{`a`, `b`, `c`}, `, `) -> `"a", "b", "c"`
