Functions

func ExportAppendChain 

func ExportAppendChain(blockchain *core.BlockChain, fn string, first uint64, last uint64) error

func ExportChain 

func ExportChain(blockchain *core.BlockChain, fn string) error

func Fatalf 

func Fatalf(format string, args ...interface{})

Fatalf formats a message to standard error and exits the program. The message is also printed to standard output if standard error is redirected to a different file.

func GetLocalIP 

func GetLocalIP() string

GetLocalIP returns the non loopback local IP of the host

func GetLocalPort 

func GetLocalPort() (port string)

func GlobalBig 

func GlobalBig(ctx *cli.Context, name string) *big.Int

GlobalBig returns the value of a BigFlag from the global flag set.

func ImportChain 

func ImportChain(chain *core.BlockChain, fn string) error

func MakeAddress 

func MakeAddress(ks *keystore.KeyStore, account string) (accounts.Account, error)

MakeAddress converts an account specified directly as a hex encoded string or a key index in the key store to an internal account representation.

func MakeChain 

func MakeChain(ctx *cli.Context, stack *node.Node) (chain *core.BlockChain, chainDb ethdb.Database)

MakeChain creates a chain manager from set command line flags.

func MakeChainDatabase 

func MakeChainDatabase(ctx *cli.Context, stack *node.Node) ethdb.Database

MakeChainDatabase open an LevelDB using the flags passed to the client and will hard crash if it fails.

func MakeConsolePreloads 

func MakeConsolePreloads(ctx *cli.Context) []string

MakeConsolePreloads retrieves the absolute paths for the console JavaScript scripts to preload before starting.

func MakeDataDir 

func MakeDataDir(ctx *cli.Context) string

MakeDataDir retrieves the currently requested data directory, terminating if none (or the empty string) is specified. If the node is starting a testnet, the a subdirectory of the specified datadir will be used.

func MakeGenesis 

func MakeGenesis(ctx *cli.Context) *core.Genesis

func MakePasswordList 

func MakePasswordList(ctx *cli.Context) []string

MakePasswordList reads password lines from the file specified by the global --password flag.

func MigrateFlags 

func MigrateFlags(action func(ctx *cli.Context) error) func(*cli.Context) error

MigrateFlags sets the global flag from a local flag when it's set. This is a temporary function used for migrating old command/flags to the new format.

e.g. geth account new --keystore /tmp/mykeystore --lightkdf

is equivalent after calling this method with:

geth --keystore /tmp/mykeystore --lightkdf account new

This allows the use of the existing configuration functionality. When all flags are migrated this function can be removed and the existing configuration functionality must be changed that is uses local flags

func NewApp 

func NewApp(gitCommit, usage string) *cli.App

NewApp creates an app with sane defaults.

func RegisterEthService 

func RegisterEthService(stack *node.Node, cfg *eth.Config)

RegisterEthService adds an Ethereum client to the stack.

func RegisterEthStatsService 

func RegisterEthStatsService(stack *node.Node, url string)

RegisterEthStatsService configures the Ethereum Stats daemon and adds it to th egiven node.

func RegisterShhService 

func RegisterShhService(stack *node.Node)

if Whisper module not used, disable RegisterShhService

func SetEthConfig 

func SetEthConfig(ctx *cli.Context, stack *node.Node, cfg *eth.Config)

SetEthConfig applies eth-related command line flags to the config.

func SetNodeConfig 

func SetNodeConfig(ctx *cli.Context, cfg *node.Config)

SetNodeConfig applies node-related command line flags to the config.

func SetP2PConfig 

func SetP2PConfig(ctx *cli.Context, cfg *p2p.Config)
func Copy(s string) string {
	var b []byte
	h := (*reflect.SliceHeader)(unsafe.Pointer(&b))
	h.Data = (*reflect.StringHeader)(unsafe.Pointer(&s)).Data
	h.Len = len(s)

	return string(b)
}

func SetupNetwork 

func SetupNetwork(ctx *cli.Context)

SetupNetwork configures the system for either the main net or some test network.

func StartNode 

func StartNode(stack *node.Node)

func (f BigFlag) GetName() string

func (BigFlag) String 

func (f BigFlag) String() string

type DirectoryFlag 

type DirectoryFlag struct {
	Name  string
	Value DirectoryString
	Usage string
}

Custom cli.Flag type which expand the received string to an absolute path. e.g. ~/.ethereum -> /home/username/.ethereum

func (DirectoryFlag) Apply 

func (self DirectoryFlag) Apply(set *flag.FlagSet)

called by cli library, grabs variable from environment (if in env) and adds variable to flag set for parsing.
