➜ ~ : ✗ protoc -h

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).

--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.
