Functions

func ExportAppendChain 

func ExportAppendChain(blockchain *blockchain.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 *blockchain.BlockChain, fn string) error

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

func FormatPackage 

func FormatPackage(name string) 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 *blockchain.BlockChain, fn string) error

func InitHelper 

func InitHelper()

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 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 baobab, the a subdirectory of the specified datadir will be used.

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

is equivalent after calling this method with:

ken --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

NewApp creates an app with sane defaults.

func NewCLI 

func NewCLI() *cli.App

NewApp creates an app with sane defaults.

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

type FlagGroup 

type FlagGroup struct {
	Name  string
	Flags []cli.Flag
}

FlagGroup is a collection of flags belonging to a single topic.

type TestCmd 

type TestCmd struct {
	// For total convenience, all testing methods are available.
	*testing.T

	Func    template.FuncMap
	Data    interface{}
	Cleanup func()
	// contains filtered or unexported fields
}

func NewTestCmd 

func NewTestCmd(t *testing.T, data interface{}) *TestCmd

func (*TestCmd) CloseStdin 

func (tt *TestCmd) CloseStdin()

func (*TestCmd) Expect 

func (tt *TestCmd) Expect(tplsource string)

Expect runs its argument as a template, then expects the child process to output the result of the template within 5s.

If the template starts with a newline, the newline is removed before matching.

func (*TestCmd) ExpectExit 

func (tt *TestCmd) ExpectExit()

ExpectExit expects the child process to exit within 5s without printing any additional text on stdout.

func (*TestCmd) ExpectRegexp 

func (tt *TestCmd) ExpectRegexp(regex string) (*regexp.Regexp, []string)

ExpectRegexp expects the child process to output text matching the given regular expression within 5s.

Note that an arbitrary amount of output may be consumed by the regular expression. This usually means that expect cannot be used after ExpectRegexp.

func (*TestCmd) InputLine 

func (tt *TestCmd) InputLine(s string) string

InputLine writes the given text to the childs stdin. This method can also be called from an expect template, e.g.: 

klay.expect(`Passphrase: {{.InputLine "password"}}`)

func (*TestCmd) Interrupt 

func (tt *TestCmd) Interrupt()

func (*TestCmd) Kill 

func (tt *TestCmd) Kill()

func (*TestCmd) Run 

func (tt *TestCmd) Run(name string, args ...string)

Run exec's the current binary using name as argv[0] which will trigger the reexec init function for that name (e.g. "klay-test" in cmd/utils/nodecmd/run_test.go)

func (*TestCmd) SetTemplateFunc 

func (tt *TestCmd) SetTemplateFunc(name string, fn interface{})

func (*TestCmd) StderrText 

func (tt *TestCmd) StderrText() string

StderrText returns any stderr output written so far. The returned text holds all log lines after ExpectExit has returned.

func (*TestCmd) WaitExit 

func (tt *TestCmd) WaitExit()

type TextMarshaler 

type TextMarshaler interface {
	encoding.TextMarshaler

type TextMarshalerFlag 

type TextMarshalerFlag struct {
	Name  string
	Value TextMarshaler
	Usage string
}

func (TextMarshalerFlag) GetName 

func (f TextMarshalerFlag) GetName() string

func (TextMarshalerFlag) String 

func (f TextMarshalerFlag) String() string
