Functions

func CheckExclusive 

func CheckExclusive(ctx *cli.Context, args ...interface{})

CheckExclusive verifies that only a single instance of the provided flags was set by the user. Each flag might optionally be followed by a string type to specialize it further.

func ExportAppendChain 

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

ExportAppendChain exports a blockchain into the specified file, appending to the file if data already exists in it.

func ExportChain 

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

ExportChain exports a blockchain into the specified file, truncating any data already present in the file.

func ExportPreimages 

func ExportPreimages(db *serodb.LDBDatabase, fn string) error

ExportPreimages exports all known hash preimages into the specified file, truncating any data already present in the file.

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 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 ImportPreimages 

func ImportPreimages(db *serodb.LDBDatabase, fn string) error

ImportPreimages imports a batch of exported hash preimages into the database.

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 serodb.Database)

MakeChain creates a chain manager from set command line flags.

func MakeChainDatabase 

func MakeChainDatabase(ctx *cli.Context, stack *node.Node) serodb.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. gero account new --keystore /tmp/mykeystore --lightkdf

is equivalent after calling this method with:

gero --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 

func RegisterDashboardService(stack *node.Node, cfg *dashboard.Config, commit string)

RegisterDashboardService adds a dashboard to the stack.

func RegisterEthService 

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

RegisterEthService adds an Sero client to the stack.

func SetDashboardConfig 

func SetDashboardConfig(ctx *cli.Context, cfg *dashboard.Config)

SetDashboardConfig applies dashboard 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 SetSeroConfig 

func SetSeroConfig(ctx *cli.Context, stack *node.Node, cfg *sero.Config)

SetSeroConfig applies sero-related command line flags to the config.

func SetupMetrics 

func SetupMetrics(ctx *cli.Context)

func SetupNetwork

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

func StartNode 

func StartNode(stack *node.Node)
