env

Each reader takes the default inline, so configuration reads as one expression rather than a lookup followed by a zero-value check.

package main

import (
	"fmt"
	"os"
	"time"

	"github.com/dobrevit/svckit/env"
)

func main() {
	os.Setenv("PORT", "9000")
	os.Setenv("FEATURE_ENABLED", "true")
	defer func() {
		os.Unsetenv("PORT")
		os.Unsetenv("FEATURE_ENABLED")
	}()

	fmt.Println(env.String("PORT", "8080"))
	fmt.Println(env.Bool("FEATURE_ENABLED", false))
	fmt.Println(env.Duration("SHUTDOWN_GRACE", 30*time.Second))
}

Output:
9000
true
30s
