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(chain *core.Core, 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(chain *core.Core, fn string) error

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

func ExportPreimages 

func ExportPreimages(db ethdb.Database, 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 GetPassPhrase 

func GetPassPhrase(text string, confirmation bool) string

GetPassPhrase displays the given text(prompt) to the user and requests some textual data to be entered, but one which must not be echoed out into the terminal. The method returns the input provided by the user.

func GetPassPhraseWithList 

func GetPassPhraseWithList(text string, confirmation bool, index int, passwords []string) string

GetPassPhraseWithList retrieves the password associated with an account, either fetched from a list of preloaded passphrases, or requested interactively from the user.

func GlobalBig 

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

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