A safe time-independent random number/string generator.

🦎RanGo

A time-independent random number/string generator.

📦Installation

First:

go get github.com/yektadev/rango

Then, add the dependency to your code:

import "github.com/yektadev/rango"

📝Simple Usage

Here's all you need to do in order to:

🔺Generate a random int:

Use:

RanGo.RnInt(startIncluded int, endNotIncluded int)

Example:

r := RanGo.RnInt(0,8)  //r ϵ {0,1,2,...,6,7}

🔺Generate a random string from a set of characters:

Use:

RanGo.RnStringFrom(length int, chars string)

Example:

r := RanGo.RnStringFrom(8,"abcd")  //r (example): "dadaadbb"

🔺Generate a random string:

Use:

RanGo.RnString(length int, containsLowercase bool, containsUppercase bool, containsNumber bool, containsSpecial bool)

Examples:

r := RanGo.RnString(18,true,true,true,true)  //r (example): "}WCg*(?w4P$<HS\jOb"

r := RanGo.RnString(18,true,false,false,false)  //r (example): "jzoqagpchhsyhotvrj"

r := RanGo.RnString(18,false,false,true,false)  //r (example): "325803510203358683"

🔧More Options

If the above functions face an error while generating a time-independent seed, the seed will be automatically generated using time.Now().UnixNano(). If you need to know whether the seed is generated time-dependent or time-independent, then use the following functions:

• RandomInt() instead of RnInt().
• RandomStringFrom() instead of RnStringFrom().
• RandomString() instead of RnString().

In case of using these functions, you'll have isSeedTimeDependent boolean as the second returned output.
