Utilities

func Pluralize(n int64) string

Usage

// Parse comma-separated list
items := strutils.CommaSeperatedList("a, b, c") // ["a", "b", "c"]

// Case-insensitive search
strutils.ContainsFold("Hello World", "world") // true

// Levenshtein distance
dist := strutils.LevenshteinDistance("kitten", "sitting") // 3

// Format duration
strutils.FormatDuration(3661000000000) // "1 hour, 1 minute and 1 second"

// Format time ago
strutils.FormatTime(time.Now().Add(-5 * time.Minute)) // "5 minutes ago"

// Format byte size
strutils.FormatByteSize(1024 * 1024) // "1 MiB"
