Functions

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 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 MakeConsolePreloads

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

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

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. gptn account new --keystore /tmp/mykeystore --lightkdf

is equivalent after calling this method with:

gptn --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 RegisterPrometheusService added in v1.0.5

func RegisterPrometheusService(stack *node.Node, config prometheus.Config)

func RegisterPtnService

func RegisterPtnService(stack *node.Node, cfg *ptn.Config)

RegisterPtnService adds an PalletOne client to the stack.

func SetDagConfig

func SetDagConfig(ctx *cli.Context, cfg *dagconfig.Config, dataDir string)

SetDagConfig applies dag related command line flags to the config.

func SetLogConfig

func SetLogConfig(ctx *cli.Context, cfg *log.Config, configDir string, isInConsole bool)

func SetNodeConfig

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

SetNodeConfig applies node-related command line flags to the config. 检查命令行中有没有 node 相关的配置,如果有的话覆盖掉cfg中的配置。

func SetP2PConfig

func SetP2PConfig(ctx *cli.Context, cfg *p2p.Config)

func SetPrometheusConfig added in v1.0.5

func SetPrometheusConfig(ctx *cli.Context, cfg *prometheus.Config)

SetDashboardConfig applies dashboard related command line flags to the config.

func SetPtnConfig

func SetPtnConfig(ctx *cli.Context, stack *node.Node, cfg *ptn.Config)

SetPtnConfig applies ptn-related command line flags to the config.

func SetTxPoolConfig

func SetTxPoolConfig(ctx *cli.Context, cfg *txspool.TxPoolConfig)
func setGPO(ctx *cli.Context, cfg *gasprice.Config) {
	if ctx.GlobalIsSet(GpoBlocksFlag.Name) {
		cfg.Blocks = ctx.GlobalInt(GpoBlocksFlag.Name)
	}
	if ctx.GlobalIsSet(GpoPercentileFlag.Name) {
		cfg.Percentile = ctx.GlobalInt(GpoPercentileFlag.Name)
	}
}

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)

Types

type BigFlag

type BigFlag struct {

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 (ds 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 (ds DirectoryFlag) GetName() string

func (*DirectoryFlag) Set

func (ds *DirectoryFlag) Set(value string)

func (DirectoryFlag) String

func (ds 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
