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

is equivalent after calling this method with:

geth --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() *cli.App

NewApp creates an app with sane defaults.
