Nested Prefixing

[syntaqx]

Allows for optional nested prefixes

type DatabaseConfig struct {
    Host     string `env:"HOST,default=localhost"`
    Port     int    `env:"PORT|DB_PORT,fallback=3306"`
    Username string `env:"USERNAME,default=root"`
    Password string `env:"PASSWORD,required"`
    Database string `env:"NAME"`
}

type Config struct {
    Database  DatabaseConfig `env:"DATABASE"`
}

Or

type DatabaseConfig struct {
    Host     string `env:"DATABASE_HOST,default=localhost"`
    Port     int    `env:"DATABASE_PORT|DB_PORT,fallback=3306"`
    Username string `env:"DATABASE_USERNAME,default=root"`
    Password string `env:"DATABASE_PASSWORD,required"`
    Database string `env:"DATABASE_NAME"`
}

type Config struct {
    Database  DatabaseConfig
}

To both work as expected.
