var ErrUnknownCommand = errors.New("unknown command")

ErrUnknownCommand is returned for an unknown command.

Functions

func MarshalJSON

func MarshalJSON(obj any) (data []byte, err error)

MarshalJSON marshals "obj" to a JSON string. It uses the "jsonpb" marshaler or Go's standard one.

We use jsonpb for protobuf messages because it is the only supported way to marshal protobuf messages to JSON. In addition to that, it's the only way to emit zero values in the JSON output. Unfortunately, jsonpb works only for protobuf messages. Therefore, we use the default marshaler for the remaining structs (which are possibly mixed protobuf and non-protobuf).

TODO(mberlin): Switch "EnumAsInts" to "false" once the frontend is

updated and mixed types will use jsonpb as well.

func PrintAllCommands

func PrintAllCommands(logger logutil.Logger)

PrintAllCommands will print the list of commands to the logger

func PrintDoubleDashDeprecationNotice added in v0.15.0

func PrintDoubleDashDeprecationNotice(wr *wrangler.Wrangler)

func RunCommand

func RunCommand(ctx context.Context, wr *wrangler.Wrangler, args []string) error

RunCommand will execute the command using the provided wrangler. It will return the actionPath to wait on for long remote actions if applicable.
