 # json2pb
-Json2pb is a command line tool for converting json files to protobuf encoding file.
+
+Json2pb是一个可以把json对象转换为Protobuf编码的命令行工具。
+
+
+	如果每一个json对象都含有_message字段来说明这个对象的类型
+	那么把Json对象用Protobuf打包只需要输入：json2pb -pmotion.proto motion.json
+
+*想要把csv文件打包的朋友们， 可以先用[evalcsv](https://github.com/randyliu/evalcsv.git)把csv文件转换为json对象。*
+
+
+Install
+-------
+
+1. Install [node.js](https://nodejs.org)
+
+2. Install with [npm](https://npmjs.org/package/json2pb)
+```
+    npm install -g json2pb
+```
+
+
+Usage
+-----
+		Usage: json2pb [options] files
+			Options:
+			-h, --help                   Display this information.
+			-v, --version                Print the compiler version.
+			-t, --tag                    The tag of storing message name, default is _message
+			-n, --namespace              Set the namespace to be built.
+			-p, --proto                  Specify the .proto file for searching class name.
+
+Example
+-------
+
+- 每一个json对象必须含有一个_message字段来说明这个对象的类型。
+
+    motion.json:
+    
+		{
+		      "_message": "motion",
+		      "rows": [

+		              "_message": "motion_row"
+		          }
+		      ]
+		    }
+
+	motion.proto:
+	
+		syntax = "proto3";
+    		message motion_row {
+	        	int32 motion_id = 1;

+    
+    		message motion {

+
+  command line:
