# generate json
proto2json -p ./json -e json ../tests/UserInfo.proto

# custom gcc --> CMakeLists.txt
SET(CMAKE_C_COMPILER "/usr/local/bin/gcc")

Example

1. tests/User.proto

syntax = "proto3";

package app.center;

message User {
    int32  id        = 1; // ID
    string nick      = 2; // nick name
    stirng name      = 3; // name
    string avatarUrl = 4; // url of avatar 
}

2. in the path build execute

./proto2json -p out ../tests/User.proto

3. build/out/app.center.User.json is the resault

{
    "fields" : 
    [
        {
            "comment" : "// ID",
            "isRepeated" : false,
            "name" : "id",
            "number" : "1",
            "type" : "int32"
        },
        {
            "comment" : "// nick name",
            "isRepeated" : false,
            "name" : "nick",
            "number" : "2",
            "type" : "string"
        },
        {
            "comment" : "// name",
            "isRepeated" : false,
            "name" : "name",
            "number" : "3",
            "type" : "stirng"
        },
        {
            "comment" : "// url of avatar ",
            "isRepeated" : false,
            "name" : "avatarUrl",
            "number" : "4",
            "type" : "string"
        }
