func MakeAddress added in v1.4.0 

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 added in v0.9.26 

func MakeChain(ctx *cli.Context, stack *node.Node) (chain *core.BlockChain, chainDb ethdb.Database)

MakeChain creates a chain manager from set command line flags.

func MakeChainDatabase added in v1.4.0 

func MakeChainDatabase(ctx *cli.Context, stack *node.Node) ethdb.Database

MakeChainDatabase open an LevelDB using the flags passed to the client and will hard crash if it fails.

func MakeConsolePreloads added in v1.4.6 

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

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

func MakeDataDir added in v1.5.0 

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 MigrateFlags added in v1.6.1 

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
