Je recherche un utilitaire de ligne de commande qui, au minimum, rendra les données binaires du protobuf sous une forme lisible par l'homme. Les options de filtrage et de sélection (sur le modèle de cut
pour le texte) seraient bien, mais l'objectif principal est de rendre les données visibles à des fins de débogage.
S'il n'y a pas d'outil définitif pour le travail, les liens vers les packages pertinents sont corrects.
Le compilateur de protocole - protoc
- a cette fonctionnalité intégrée via le --decode
et --decode_raw
drapeaux. Il s'agit du même outil que vous utilisez pour générer du code à partir d'un .proto
le fichier est donc probablement déjà installé.
Par exemple:
protoc --decode_raw < message.bin
Ou en utilisant le .proto
fichier:
protoc --decode mypkg.MyType myschema.proto < message.bin
Voici la --help
texte:
Usage: protoc [OPTION] PROTO_FILES
Parse PROTO_FILES and generate output based on the options given:
-IPATH, --proto_path=PATH Specify the directory in which to search for
imports. May be specified multiple times;
directories will be searched in order. If not
given, the current working directory is used.
--version Show version info and exit.
-h, --help Show this text and exit.
--encode=MESSAGE_TYPE Read a text-format message of the given type
from standard input and write it in binary
to standard output. The message type must
be defined in PROTO_FILES or their imports.
--decode=MESSAGE_TYPE Read a binary message of the given type from
standard input and write it in text format
to standard output. The message type must
be defined in PROTO_FILES or their imports.
--decode_raw Read an arbitrary protocol message from
standard input and write the raw tag/value
pairs in text format to standard output. No
PROTO_FILES should be given when using this
flag.
-oFILE, Writes a FileDescriptorSet (a protocol buffer,
--descriptor_set_out=FILE defined in descriptor.proto) containing all of
the input files to FILE.
--include_imports When using --descriptor_set_out, also include
all dependencies of the input files in the
set, so that the set is self-contained.
--include_source_info When using --descriptor_set_out, do not strip
SourceCodeInfo from the FileDescriptorProto.
This results in vastly larger descriptors that
include information about the original
location of each decl in the source file as
well as surrounding comments.
--error_format=FORMAT Set the format in which to print errors.
FORMAT may be 'gcc' (the default) or 'msvs'
(Microsoft Visual Studio format).
--print_free_field_numbers Print the free field numbers of the messages
defined in the given proto files. Groups share
the same field number space with the parent
message. Extension ranges are counted as
occupied fields numbers.
--plugin=EXECUTABLE Specifies a plugin executable to use.
Normally, protoc searches the PATH for
plugins, but you may specify additional
executables not in the path using this flag.
Additionally, EXECUTABLE may be of the form
NAME=PATH, in which case the given plugin name
is mapped to the given executable even if
the executable's own name differs.
--cpp_out=OUT_DIR Generate C++ header and source.
--Java_out=OUT_DIR Generate Java source file.
--python_out=OUT_DIR Generate Python source file.
