Types

type Config

type Config struct {
	*Flags
	Lookup        func(string) ([]net.IP, error)
	Dial          func(string, string, time.Duration) (net.Conn, error)
	MiningAddrs   []util.Address
	MinRelayTxFee util.Amount
	Whitelists    []*net.IPNet
	SubnetworkID  *externalapi.DomainSubnetworkID // nil in full nodes
}

Config defines the configuration options for BTCD.

See loadConfig for details on the configuration load process.

func DefaultConfig

func DefaultConfig() *Config

DefaultConfig returns the default BTCD configuration

func LoadConfig

func LoadConfig() (*Config, error)

LoadConfig initializes and parses the config using a config file and command line options.

The configuration proceeds as follows:

1. Start with a default config with sane settings
2. Pre-parse the command line to check for an alternative config file
3. Load configuration file overwriting defaults with any specified options
4. Parse CLI options and overwrite/add any specified options

The above results in BTCD functioning properly without any config settings while still allowing the user to override settings with config files and command line options. Command line options always take precedence.
