gengo is a Go Module containing utility functions to generate random data.
This module is also developed having performance and resource usage considerations in mind, so it can be used in production environments.
Download and install the Go module
go get -u github.com/FlavioCFOliveira/gengoTo start generating random data you just need to import the package and start using the package API as follows on this quick example:
package main
import (
"fmt"
"github.com/FlavioCFOliveira/gengo"
)
func main() {
// Generate a random alfanumeric string with 33 chars
randString := gengo.StringAlphanumeric(33)
fmt.Println(randString)
}The gengo.String(length, sourceChars) func generates a random string with a given length using only characters of a given source..
// Specify a variable containing the characters you want to be used on the new string
sourceChars := "YourCustomSouce0fCh4r4ct3rs"
customRandString := gengo.String(33, sourceChars)
fmt.Println(customRandString)The gengo.StringAllChars(length int) func generates a random string with a given length containing all the predefined alphabetic, alphanumeric and symbols characters.
This uses the predefined constant string AllChars as characters source reference.
// generates using letters, numbers and symbols
randomString := gengo.StringAllChars(33)
fmt.Println(randomString)The gengo.StringAlphanumeric(length int) func generates a random string with a given length containing all the predefined alphabetic and alphanumeric characters.
This uses the predefined constant string Alphanumeric as characters source reference.
// generates using letters and numbers
randomString := gengo.StringAlphanumeric(33)
fmt.Println(randomString)The gengo.Alphabetic(length int) func generates a random string with a given length containing all the predefined alphabetic characters.
This func uses the predefined constant string Alphabetic as characters source reference.
There are also two variants to generate upper case and lowe case only strings, that uses the predefined constant string AlphabeticUppercase and AlphabeticLowercase as characters source reference.
// upper and lower case characters
randomString := gengo.Alphabetic(33)
fmt.Println(randomString)
// upper case only characters
upperString := gengo.StringAlphabeticUppercase(33)
fmt.Println(randomString)
// lower case only characters
lowerString := gengo.StringAlphabeticLowercase(33)
fmt.Println(randomString)The gengo.StringNumeric(length int) func generates a random string with a given length containing all the predefined numeric characters.
This func uses the predefined constant string Numeric as characters source reference.
randomString := gengo.StringNumeric(33)
fmt.Println(randomString)The gengo.StringHexadecimal(length int) func generates a random string with a given length containing all the predefined Hexadecimal characters.
This func uses the predefined constant string Hexadecimal as characters source reference.
randomString := gengo.StringHexadecimal(33)
fmt.Println(randomString)The gengo.StringSymbols(length int) func generates a random string with a given length containing all the predefined Hexadecimal characters.
This func uses the predefined constant string Symbols as characters source reference.
randomString := gengo.StringSymbols(33)
fmt.Println(randomString)
