func FromContext(ctx context.Context) *pflag.FlagSet

FromContext returns the FlagSet ctx carries. It panics in case ctx carries no FlagSet.

func GetApp 

func GetApp(ctx context.Context) string

GetApp is shorthand for GetString(ctx, App).

func GetAppConfigFilePath 

func GetAppConfigFilePath(ctx context.Context) string

GetAppConfigFilePath is shorthand for GetString(ctx, AppConfigFilePath).

func GetBindAddr added in v0.1.59 

func GetBindAddr(ctx context.Context) string

GetBindAddr is shorthand for GetString(ctx, BindAddr).

func GetBool 

func GetBool(ctx context.Context, name string) bool

GetBool returns the value of the named boolean flag ctx carries.

func GetBuildOnly 

func GetBuildOnly(ctx context.Context) bool

func GetDetach 

func GetDetach(ctx context.Context) bool

GetDuration returns the value of the named duration flag ctx carries.

func GetFlagsName added in v0.1.1 

func GetFlagsName(ctx context.Context, ignoreFlags []string) []string

GetFlagsName returns the name of flags that have been set except unwanted flags.

func GetFloat64 added in v0.1.75 

func GetFloat64(ctx context.Context, name string) float64

GetFloat64 returns the value of the named int flag ctx carries. It panics in case ctx carries no flags or in case the named flag isn't an int one.

func GetInt 

func GetInt(ctx context.Context, name string) int

GetInt returns the value of the named int flag ctx carries. It panics in case ctx carries no flags or in case the named flag isn't an int one.

func GetLocalOnly 

func GetLocalOnly(ctx context.Context) bool

func GetMachineGuest added in v0.1.86 

func GetMachineGuest(ctx context.Context, guest *api.MachineGuest) (*api.MachineGuest, error)

Returns a MachineGuest based on the flags provided overwriting a default VM

func GetString(ctx context.Context, name string) string

GetString returns the value of the named string flag ctx carries.

func GetStringArray added in v0.1.1 

func GetStringArray(ctx context.Context, name string) []string

GetStringArray returns the values of the named string flag ctx carries. Preserves commas (unlike the following `GetStringSlice`): in `--flag x,y` the value is string[]{`x,y`}. This is useful to pass key-value pairs like environment variables or build arguments.

func GetStringSlice 

func GetStringSlice(ctx context.Context, name string) []string

GetStringSlice returns the values of the named string flag ctx carries. Can be comma separated or passed "by repeated flags": `--flag x,y` is equivalent to `--flag x --flag y`.

func GetYes 

func GetYes(ctx context.Context) bool

GetYes is shorthand for GetBool(ctx, Yes).

func IsSpecified added in v0.0.475 

func IsSpecified(ctx context.Context, name string) bool

IsSpecified returns whether a flag has been specified at all or not. This is useful, for example, when differentiating between 0/"" and unspecified.

func NewContext 

func NewContext(ctx context.Context, fs *pflag.FlagSet) context.Context

NewContext derives a context that carries fs from ctx.

func SetString added in v0.0.530 

func SetString(ctx context.Context, name, value string) error

SetString sets the value of the named string flag ctx carries.
