Overview ¶

Package printer is the port through which a rendered document becomes a PDF. The engine and the API ask for a Printer and never for a browser; the chromium adapter beside this package is the one implementation today, and None is what runs where no browser is installed.

var ErrUnavailable = errors.New("no PDF printer is available")

ErrUnavailable is returned by a Printer that cannot print on this machine. Callers treat it as "no PDF", never as a failure of the document itself.

Types ¶

type Func ¶

type Func func(ctx context.Context, html []byte) ([]byte, error)

Func adapts a function to the Printer interface.

func (Func) Print ¶

func (f Func) Print(ctx context.Context, html []byte) ([]byte, error)

Print calls f.

type None ¶

type None struct{}

None is the Printer for a deployment without a browser: every call answers ErrUnavailable.

func (None) Print ¶

func (None) Print(context.Context, []byte) ([]byte, error)

Print always returns ErrUnavailable.

type Printer ¶

type Printer interface {
	// Print returns the PDF bytes for html, or ErrUnavailable (possibly
	// wrapped) when nothing on this machine can print.
	Print(ctx context.Context, html []byte) ([]byte, error)
}

Printer prints HTML to PDF.
