  import(
    "github.com/thanhpk/randstr"
    "fmt"
  )

  func main() {
    for i := 0; i < 5; i++ {
      token := randstr.Hex(16) // generate 128-bit hex string
      fmt.Println(token)
    }
  }
  // Output:
  // 67aab2d956bd7cc621af22cfb169cba8
  // 226eeb52947edbf3e97d1e6669e212c2

Generate a random ASCII string

token := randstr.String(16) // generate a random 16 character length string

Running example

  package main
  import(
    "github.com/thanhpk/randstr"
    "fmt"
  )

  func main() {
    for i := 0; i < 5; i++ {
      token := randstr.String(16)
      fmt.Println(token)

Generate a random decimal number string

token := randstr.Dec(16) // generate a random 16 length string of decimal number

Running example

  package main
  import(
    "github.com/thanhpk/randstr"
    "fmt"
  )

  func main() {
    for i := 0; i < 5; i++ {
      token := randstr.Dec(16)
      fmt.Println(token)
    }
  }

randstr's Issues

Wrong Example

Examples in README doesn't work:
token := randstr.Hex(16) // generate 128-bit hex string
instead of
token := ranstr.Hex(16) // generate 128-bit hex string

Version 1.0.3 not Tags correctly for go modules

GO111MODULE=on go build
produces

main.go:10:2: import "github.com/thanhpk/randstr" is a program, not an importable package

This happens because your 1.0.3 Tag is mission the prepending 'v'

That's the reason why go in module mode is using v1.0.2 which has a.go inside which is package main.

Could you please fix the Tag ?
