zproto

A simple protocol buffer for lua

Description

• Struct consist of members, the type of which can be basic type or other struct type

• Basic type can be 'boolean' or 'integer' or 'long' or 'string'

• All comment line begin with '#'

• All struct or field name begin with 'a-zA-Z'

• All field name must be defined after the character '.'

• Struct or field name and field tag must be unique in it's scope

• Field tag must large then 0 and defined by ASC

• When the suffix of type(include struct and basic type) is [], it means this field is array

• Struct can be defined as follows:

    #only the struct which has no parent can specify the protocol
    #protocol is aka struct name when it's explicitly specified
    #protocol is option and default value is '0'
    #protocol value can be queryed by zproto:tag@zproto.lua
    name [protocol] {
    	.name:type 1
    	...
    }
  

• A sample protocol define may like this:

    #comments line
    info {
    	.name:string 1
    	.age:integer 2
    	.girl:boolean 3
    }
    packet 0xfe {
    	phone {
    		.home:integer 1
    		.work:long 2
    	}
    	.phone:phone 1
    	.info:info[] 2
    	.address:string 3
    	.luck:integer[] 4
    }
  

##luabind

This code is a simply lua binding of zproto in luabind folder

It provide a simple test code and you can run it as follow:

• Download lua-5.3 or later and extract into luabind/lua53
• Execute 'make linux' or 'make macosx' to build zproto.so
• Execute './test' to run the test code

##cppbind and csbind

This code is a simply [C++|C#] binding of zproto in [cppbind|csbind] folder

It also provide a simple test code and you can run it as follow:

• Execute 'make' to build a executable file named 'zproto', 'zproto' used to generate [C++|C#] bind code from a file defined as zproto syntax
• Execute './zproto test.zproto' to generate [C++|C#] bind code for test.zproto
• Execute 'make test' to build a test program
• Execute './test' to run the test code.
