Go Package

Example usage to generate an c4 ID for a file.

package main

import (
  "fmt"
  "io"
  "os"

  // import 'asset' asset identification
  "github.com/etcenter/c4/asset"
)

func main() {
  file := "main.go"
  f, err := os.Open(file)
  if err != nil {
    panic(err)
  }
  defer f.Close()

  // create a ID encoder.
  e := asset.NewIDEncoder()
  // the encoder is an io.Writer
  _, err = io.Copy(e, f)
  if err != nil {
    panic(err)
  }
  // ID will return an *asset.ID.
  // Be sure to be done writing bytes before calling ID()
  id := e.ID()
  // use the *asset.ID String method to get the c4id string
  fmt.Printf("C4id of \"%s\": %s\n", file, id.String())
  return
}

Output:

>go run main.go 
C4id of "main.go": c44jVTEz8y7wCiJcXvsX66BHhZEUdmtf7TNcZPy1jdM6S14qqrzsiLyoZRSvRGcAMLnKn4zVBvAFimNg14NFKp46cC
