Function HumanReadableBytes

pkg/util/util.go:239–250

HumanReadableBytes converts a byte count into a human-readable string, e.g. 2.5 MiB there are about a zillion golang packages for formatting bytes as human-readable values, the top search result of which is https://pkg.go.dev/github.com/dustin/go-humanize. However, this package is large and does too

(b int64)

// https://pkg.go.dev/github.com/dustin/go-humanize. However, this package is large and does too much, there's no need to use it
// when we can use this trivial tutorial one instead: https://programming.guide/go/formatting-byte-size-to-human-readable-format.html
func HumanReadableBytes(b int64) string {
	const unit = 1024
	if b < unit {
		return fmt.Sprintf("%d B", b)
	}
	div, exp := int64(unit), 0
	for n := b / unit; n >= unit; n /= unit {
		div *= unit
		exp++
	}
	return fmt.Sprintf("%.1f %ciB", float64(b)/float64(div), "KMGTPE"[exp])
}

// SplitString splits the input string into components based on delimiter characters.
// we want to pick up empty entries here; so "::5" and ":pterm:5" should both return THREE components, rather than one or two
