Golang implementation to manage environment variables in system.

Golang + Environment = gonv

gonv (Golang eNVironment) is a Golang implementation to manage environment variables in operating system.
You can see an extended doc in godocs.

Install it writing in terminal:

go get github.com/fmorenovr/gonv

Example:

  import(
    "fmt"
    "github.com/jenazads/gonv"
  )

  func main(){
    // using system environmental variables
    gonv.SetEnv("BOOL", true)
    isBool, _ := gonv.GetBoolEnv("BOOL")
    username, _:= gonv.GetEnv("USER") // return $USER system variable

    fmt.Println(username, ", ", isBool)
    
    gonv.SetEnv("NAME", "Jenazads")
    nameSystem ,_ := gonv.GetEnv("NAME")
    fmt.Println("name:", nameSystem)
    gonv.UpdateEnv("NAME", 4)
    nameUpdatedsystem, _ := gonv.GetIntEnv("NAME")
    fmt.Println("name updated:", nameUpdatedsystem)
    
    // using object environmental variables
    gonvObject := gonv.NewGonv()
    gonvObject.SetEnv("BOOL", true)
    isBool, _ = gonvObject.GetBoolEnv("BOOL")
    usernameObj,_ := gonvObject.GetEnv("USER") // return nil
    
    fmt.Println(usernameObj, ", ", isBool)
    
    gonvObject.SetEnv("NAME", "Jenazads")
    nameLocal, _ := gonvObject.GetEnv("NAME")
    fmt.Println("name:", nameLocal)
    fmt.Println(gonvObject)

    gonvObject.UpdateEnv("NAME", 4)
    nameLocal, _ = gonv.GetIntEnv("NAME") // we can set another type because is interface type !
    fmt.Println("name updated:", nameLocal)
    
    fmt.Println(gonvObject)
  }
