Golang InitWithPrefix Examples

Example #1

File: envconfig_test.go Project: mozilla-services/go-syncstorage

func TestParsePrefixedStruct(t *testing.T) {
	var conf struct {
		Name string
	}

	os.Setenv("NAME", "")
	os.Setenv("FOO_NAME", "")

	os.Setenv("NAME", "bad")
	err := envconfig.InitWithPrefix(&conf, "FOO")
	require.NotNil(t, err)

	os.Setenv("FOO_NAME", "good")
	err = envconfig.InitWithPrefix(&conf, "FOO")
	require.Nil(t, err)
	require.Equal(t, "good", conf.Name)
}

Example #2

File: example_test.go Project: anujwalia/chimp

func ExampleInitWithPrefix() {
	var conf struct {
		Name string
	}

	os.Setenv("NAME", "")
	os.Setenv("FOO_NAME", "")

	os.Setenv("NAME", "foobar")

	err := envconfig.InitWithPrefix(&conf, "FOO")
	fmt.Println(err)

	os.Setenv("FOO_NAME", "foobar")
	err = envconfig.InitWithPrefix(&conf, "FOO")
	fmt.Println(err)

	fmt.Println(conf.Name)
	// Output:
	// envconfig: key FOO_NAME not found
	// <nil>
	// foobar
}
