conftags

Similar to github.com/caarlos0/env but with default decoupled from environment. It also doesn't support slices.

This library intends to work as the last step in the filling of a configuration struct. Assuming that environment variables are the highest priority configuration values, you could first parse a configuration file, and then parse this struct with this library. The last resort is the default which will fill the struct field only if it has the zero value for its own type.

Usage

type MyConf struct {
    Int      int           `env:"INT" default:"10"`
    String   string        `env:"STRING"`
    Duration time.Duration `env:"DURATION" default:"1h"`
}

func (ms *MyConf) Parse() error {
    return conftags.Parse(ms)
}
