Functions

func AssertStrings

func AssertStrings(as []any) ([]string, error)

AssertStrings converts a slice of any into a slice of strings.

func BytesAreEmptyIsh

func BytesAreEmptyIsh(b []byte) bool

BytesAreEmptyIsh checks if the provided byte slice is practically empty. Can handle cases where a nil pointer or empty struct were marshalled to YAML.

func CountDir

func CountDir(dir string) (int, int64, error)

CountDir returns the number of files in a directory and the total size.

func FilterNil

func FilterNil[T any](list []*T) []*T

FilterNil filters nil entries from a list.

func FmtSemver

func FmtSemver(s string) string

FmtSemver forces a string formatted as a semver version with "v" prefix.

func IndexIfOK

func IndexIfOK[T any](list []T, i int) (T, bool)

IndexIfOK returns the value at the index if it is a valid index for the slice.

func PrettyBytes

func PrettyBytes(size int64) string

PrettyBytes returns the number of bytes formatted for human readability.

func TerminalWidth

func TerminalWidth(fallback int) int

TerminalWidth returns the width of the terminal, using fallback if it can't determine width.

func ToAny

func ToAny[T any](list []T) []any

ToAny casts a slice to []any.
