Python protocol buffers compiler

A python protocol buffers compiler

Converts from .proto to:

• python protorpc

• Closure library externs

• Closure library goog.proto2

Usage

pyprotoc protofile

Usage:

pyprotoc

usage: pyprotoc [-h] [--format {closure,externs,python}] paths [paths ...]

positional arguments:
  paths

optional arguments:
  -h, --help            show this help message and exit
  --format {closure,externs,python}

Example

Input file (test.proto):

option javascript_package = "com.example";

message Item {
  optional string aString = 1;
  optional int32 aNumber = 2;
  required string aRequiredString = 3;
  repeated string aRepeatedString = 4;
}

Generated python rpc (protopy –format python test.proto):

from protorpc import messages

class Item(messages.Message):
    aString = messages.StringField(1)
    aNumber = messages.IntegerField(2)
    aRequiredString = messages.StringField(3, required=True)
    aRepeatedString = messages.StringField(4, repeated=True)

Generated javascript externs(protopy –format externs test.proto):

/** @constructor */
com.example.Item = function(){};

/** @type {string} */
com.example.Item.prototype.aString;

/** @type {number} */
com.example.Item.prototype.aNumber;

/** @type {string} */
com.example.Item.prototype.aRequiredString;

/** @type {[string]} */
com.example.Item.prototype.aRepeatedString;
