func NewError

func NewError(code, message string, details map[string]any) *CLIError

func WrapError

func WrapError(code, message string, cause error, details map[string]any) *CLIError

func (*CLIError) Error

func (e *CLIError) Error() string

func (*CLIError) ExitCode

func (e *CLIError) ExitCode() int

func (*CLIError) Unwrap

func (e *CLIError) Unwrap() error

type Options

type Options struct {
	Format    string
	Compact   bool
	Fields    []string
	StartedAt time.Time
}

Options controls one command invocation's output.

	// contains filtered or unexported fields
}

Printer writes exactly one command result to stdout.

func NewPrinter

func NewPrinter(out io.Writer, options Options) *Printer

func (*Printer) Failure

func (p *Printer) Failure(cliErr *CLIError) error

func (*Printer) Raw

func (p *Printer) Raw(data []byte) error

func (*Printer) Success

func (p *Printer) Success(data any) error
