# ternary

[![Build Status](https://travis-ci.org/otiai10/ternary.svg?branch=master)](https://travis-ci.org/otiai10/ternary)

Ternary expression for golang, to enjoy code-golf :golf:

```go

port := ternary.String(os.Getenv("PORT"))("8080")

// Returns "8080" if "PORT" == ""

```

# why

If you want

```go

status := 500

if flag {

    status = 200

}

```

Write

```go

status := ternary.If(flag).Int(200, 500)

```

If you want

```go

res := map[string]interface{}{

    "user":       user,

    "expired_at": nil,

}

if user.Expire() {

    res["expire_at"] = time.Now()

}

json.NewEncoder(wr).Encode(res)

```

Write

```go

json.NewEncoder(wr).Encode(map[string]interface{}{

    "user":       user,

    "expired_at": ternary.If(user.Expire()).Interface(time.Now(), nil),

})

```

Enjoy :golf: !
