# Flag Source The flag source reads config from flags ## Format We expect the use of the `flag` package. Upper case flags will be lower cased. Dashes will be used as delimiters. ### Example ``` dbAddress := flag.String("database_address", "127.0.0.1", "the db address") dbPort := flag.Int("database_port", 3306, "the db port) ``` Becomes ```json { "database": { "address": "127.0.0.1", "port": 3306 } } ``` ## New Source ```go flagSource := flag.NewSource( // optionally enable reading of unset flags and their default // values into config, defaults to false IncludeUnset(true) ) ``` ## Load Source Load the source into config ```go // Create new config conf := config.NewConfig() // Load flag source conf.Load(flagSource) ```
