Functions

func ApplyInputSourceValues 

func ApplyInputSourceValues(context *cli.Context, inputSourceContext InputSourceContext, flags []cli.Flag) error

ApplyInputSourceValues iterates over all provided flags and executes ApplyInputSourceValue on flags implementing the FlagInputSourceExtension interface to initialize these flags to an alternate input source.

func InitInputSource 

func InitInputSource(flags []cli.Flag, createInputSource func() (InputSourceContext, error)) cli.BeforeFunc

InitInputSource is used to to setup an InputSourceContext on a cli.Command Before method. It will create a new input source based on the func provided. If there is no error it will then apply the new input source to any flags that are supported by the input source

func InitInputSourceWithContext 

func InitInputSourceWithContext(flags []cli.Flag, createInputSource func(context *cli.Context) (InputSourceContext, error)) cli.BeforeFunc

InitInputSourceWithContext is used to to setup an InputSourceContext on a cli.Command Before method. It will create a new input source based on the func provided with potentially using existing cli.Context values to initialize itself. If there is no error it will then apply the new input source to any flags that are supported by the input source

func NewYamlSourceFromFlagFunc added in v1.14.0 

func NewYamlSourceFromFlagFunc(flagFileName string) func(context *cli.Context) (InputSourceContext, error)

NewYamlSourceFromFlagFunc creates a new Yaml InputSourceContext from a provided flag name and source context.
