Functions ¶
func ExportAppendChain ¶
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 ImportChain ¶
func ImportChain(chain *core.BlockChain, fn string) error
func MakeAddress ¶
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 MakeChainDatabase ¶
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 MakePasswordList ¶
func MakePasswordList(ctx *cli.Context) []string
MakePasswordList reads password lines from the file specified by the global --password flag.
func MigrateFlags ¶
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. smc account new --keystore /tmp/mykeystore --lightkdf
is equivalent after calling this method with:
smc --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 RegisterDashboardService ¶
RegisterDashboardService adds a dashboard to the stack.
func RegisterEthService ¶
RegisterEthService adds an Ethereum client to the stack.
func RegisterEthStatsService ¶
RegisterEthStatsService configures the Ethereum Stats daemon and adds it to th egiven node.
func RegisterShhService ¶
RegisterShhService configures Whisper and adds it to the given node.
func SetDashboardConfig ¶
SetDashboardConfig applies dashboard related command line flags to the config.
func SetEthConfig ¶
SetEthConfig applies eth-related command line flags to the config.
func SetNodeConfig ¶
SetNodeConfig applies node-related command line flags to the config.
func SetP2PConfig ¶
func SetShhConfig ¶
SetShhConfig applies shh-related command line flags to the config.
func SetupNetwork ¶
func SetupNetwork(ctx *cli.Context)
SetupNetwork configures the system for either the main net or some test network.
Types ¶
type BigFlag ¶
BigFlag is a command line flag that accepts 256 bit big integers in decimal or hexadecimal syntax.
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.
func (DirectoryFlag) GetName ¶
func (self DirectoryFlag) GetName() string
func (*DirectoryFlag) Set ¶
func (self *DirectoryFlag) Set(value string)
func (DirectoryFlag) String ¶
func (self DirectoryFlag) String() string
type DirectoryString ¶
type DirectoryString struct {
Value string
}
Custom type which is registered in the flags library which cli uses for argument parsing. This allows us to expand Value to an absolute path when the argument is parsed
func (*DirectoryString) Set ¶
func (self *DirectoryString) Set(value string) error
func (*DirectoryString) String ¶
func (self *DirectoryString) String() string
