randomutil

Library containing various random helpers

Get a random integer

number := randomutil.Rand(0, 20)

Get a random float

number := randomutil.Rand(-10.0, 10.0)

Get a random string

str = randomutil.String(20, randomutil.AsciiLetters)

Get a random choice

sequence := []string{"abc", "def", "ghi", "jkl"}
item := randomutil.Choice(sequence)

Get multi random choices

sequence := []string{"abc", "def", "ghi", "jkl"}
subsequence := randomutil.Choices(sequence, 2)

Shuffle

sequence := []string{"abc", "def", "ghi", "jkl"}
sequence = randomutil.Shuffle(sequence)
