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

{
    "database": {
        "address": "127.0.0.1",
        "port": 3306
    }
}

New Source

flagSource := flag.NewSource()

Load Source

Load the source into config

// Create new config
conf := config.NewConfig()

// Load file source
conf.Load(flagSource)

Functions

func NewSource

func NewSource(opts ...source.Option) source.Source

NewSource returns a config source for integrating parsed flags. Hyphens are delimiters for nesting, and all keys are lowercased.

Example:

dbhost := flag.String("database-host", "localhost", "the db host name")

{
    "database": {
        "host": "localhost"
    }
}
