env

A small library for populating structs with environment values.

No external dependencies, this is only dealing with environment and no files.

An example how to use it would be

type MyStruct struct {
	Field1 string `env:"FIELD_1"`
	Field2 int    `env:"FIELD_2"`
}

myStruct := MyStruct{}
env.PopulateWithEnv(&myStruct)

//you should see the data in your struct
fmt.Println(myStruct)

It supports also structs inside structs by taging it with obj:""

type MyStruct struct {
	Field1 string `env:"FIELD_1"`
	Field2 int    `env:"FIELD_2"`
}

type MainStruct struct {
	MyStruct `obj:"ref"`
}

struct := MainStruct{}
env.PopulateWithEnv(&struct)

//you should see the data in your struct
fmt.Println(struct)
