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(
// optionally enable reading of unset flags and their default
// values into config, defaults to false
IncludeUnset(true)
)
Load Source
Load the source into config
// Create new config
conf := config.NewConfig()
// Load flag source
conf.Load(flagSource)
