env

environment config loader

Initialize a struct from the process environment.

type Example struct {
    NumItems    int             `env:"PROC_NUM_ITEMS,33"`                   // With a default value of 33
    KeyName     string          `env:"PROC_KEY_NAME"`                       // With no default
    EnableThing bool            `env:"PROC_ENABLE_THING,f"`                 // Accepts true,t,1 for true and false,f,0 for false
    Duration    time.Duration   `env:"PROC_DUR_SOMETHING,10s,duration"`     // Treats inputs as durations
    Names       []string        `env:"PROC_NAMES,systemd;sshd;hello world"  // Slice (strings only)
    NamesSet    map[string]any  `env:"PROC_NAMES_SET,systemd;sshd"          // Map of strings as keys
}
