func FilepathAsJsonpb ¶

func FilepathAsJsonpb(path string) string

FilepathAsJsonpb returns a copy of path, with the extension changed to ".jsonpb". If path is the empty string, an empty string is returned. Note that this function makes no attempt to check if the input path already has a jsonproto extension; i.e. if path is "a/b/test.jsonpb", the exact same path will be returned. Thus, it is up to the caller to check the returned path is different if this is required.

func ReadBinaryOrJSONPb ¶

func ReadBinaryOrJSONPb(path string, m protov1.Message) error

ReadBinaryOrJSONPb reads path into m, attempting to parse as both a binary and json encoded proto.

This function is meant as a convenience so the CLI can take either json or binary protos as input. This function guesses at whether to attempt to parse as binary or json first based on path's suffix.

func ReadJsonl ¶

func ReadJsonl[M proto.Message](inPath string, ctor func() M) ([]M, error)

ReadJsonl parses the newline-delimited jsonprotos in inPath. ctor must return a new empty proto to parse each line into.

func WriteJsonl ¶

func WriteJsonl[M proto.Message](messages []M, outPath string) error

WriteJsonl writes a newline-delimited json file containing messages to outPath.
