Functions

func FlagString

func FlagString(f cli.Flag) string

FlagString prints a single flag in help.

func Merge

func Merge(groups ...[]cli.Flag) []cli.Flag

Merge merges the given flag slices.

func MigrateGlobalFlags

func MigrateGlobalFlags(ctx *cli.Context)

MigrateGlobalFlags makes all global flag values available in the context. This should be called as early as possible in app.Before.

Example:

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

is equivalent after calling this method with:

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

i.e. in the subcommand Action function of 'account new', ctx.Bool("lightkdf) will return true even if --lightkdf is set as a global option.

This function may become unnecessary when https://github.com/urfave/cli/pull/1245 is merged.

func NewApp

func NewApp(gitCommit, gitDate, usage string) *cli.App

NewApp creates an app with sane defaults.
