Types

type BundleReaderWriter

type BundleReaderWriter interface {
	ReadBundleData(context.Context, *GlobalOptions) (*wrapper.BundleWrapper, error)
	WriteBundleData(context.Context, *wrapper.BundleWrapper, *GlobalOptions) error
	WriteStructuredContents(context.Context, interface{}, *GlobalOptions) error
}

BundleReaderWriter provides a mockable reading / writing interface for reading / writing bundle data.

func NewBundleReaderWriter

func NewBundleReaderWriter(rw files.FileReaderWriter, stdio StdioReaderWriter) BundleReaderWriter

NewBundleReaderWriter creates a new BundleReaderWriter.

type CobraActionFunc

type CobraActionFunc func(cmd *cobra.Command, args []string)

CobraActionFunc provides a common type for all Cobra commands.

func ContextAction

func ContextAction(ctx context.Context, f ContextActionFunc) CobraActionFunc

ContextAction returns a CobraActionFunc for a provided ContextActionFunc.

type ContextActionFunc

type ContextActionFunc func(ctx context.Context, cmd *cobra.Command, args []string)

ContextActionFunc is a common type for providing a context to a Cobra function.

type GlobalOptions

type GlobalOptions struct {
	// InputFile is a path to an input file. If a file is not specified, it's
	// assumed the input is provided via STDIN.
	InputFile string

	// InputFormat is the text format for the input. By default, assumes YAML
	// but also can be JSON.
	InputFormat string

	// OutputFormat is the the format for any output. By default, assumes YAML.
	OutputFormat string

	// Inline indicates whether to inline the components in the bundle builders
	// or component builders before doing any processing.
	Inline bool
}

GlobalOptions are options that apply to all commands

func (*GlobalOptions) Copy

func (g *GlobalOptions) Copy() *GlobalOptions

Copy creates an options copy.

type RealStdioReaderWriter

type RealStdioReaderWriter struct{}

RealStdioReaderWriter provides a real STDIN / STDOUT implementation.

func (*RealStdioReaderWriter) ReadAll

func (r *RealStdioReaderWriter) ReadAll() ([]byte, error)

ReadAll reads all the input from STDIN.

func (*RealStdioReaderWriter) Write

func (r *RealStdioReaderWriter) Write(b []byte) (int, error)

Write writes content to STDOUT.

type StdioReaderWriter

type StdioReaderWriter interface {
	ReadAll() ([]byte, error)
	io.Writer
}

StdioReaderWriter can read from STDIN and write to STDOUT.
