Flag Source

The flag s 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(
// optionally enable reading of unset flags and their default
// values into config, defaults to false
IncludeUnset(true)
)

Load Source

Load the s into config

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

// Load flag s
conf.Load(flagSource)
