Go env
GoLang package to load environment variables from
.env.
Installation
Native
$ go get github.com/zhooravell/go-env
dep
$ dep ensure -add github.com/zhooravell/go-env
Usage
package main
import (
"github.com/zhooravell/go-env"
"log"
)
func init() {
if err := env.Load(); err != nil {
log.Fatal(err)
}
}
func main() {
s := env.GetVar("ENV_STRING", "")
b, _ := env.GetBoolVar("ENV_BOOL", false)
i, _ := env.GetIntVar("ENV_INT", 0)
i8, _ := env.GetInt8Var("ENV_INT8", 0)
i16, _ := env.GetInt16Var("ENV_INT16", 0)
i32, _ := env.GetInt32Var("ENV_INT32", 0)
i64, _ := env.GetInt32Var("ENV_INT64", 0)
f32, _ := env.GetFloat32Var("ENV_FLOAT32", 0)
f64, _ := env.GetFloat64Var("ENV_FLOAT64", 0)
log.Println("string: ", s)
log.Println("bool: ", b)
log.Println("int: ", i)
log.Println("int8: ", i8)
log.Println("int16: ", i16)
log.Println("int32: ", i32)
log.Println("int64: ", i64)
log.Println("float32: ", f32)
log.Println("float64: ", f64)
}
