lua-pb

A Protocol Buffer implementation that runs on World of Warcraft Addons. The lua-pb is based on the work of https://github.com/Neopallium/lua-pb by Neopallium

Generate lua stub for your addon

• install lpge

luarocks install lpeg

• generate with saveast.lua

lua saveast.lua VARNAME < FILE.proto > STUB.lua

exmaple for using person.proto in wowtest folder

lua saveast.lua pbperson < person.proto > wowtest/person.lua

Import in your addon

You have two choices to use lua-pb as a library

As files inside your addon

1. Download relase zip from https://www.wowace.com/projects/protobuf/files
2. Copy lua-pb folder to your addon
3. Add path\to\lua-pb\lua-pb.xml in your .toc file
4. Add path\to\pbstub.lua in your .toc file

After loaded, lua-pb would be availiable in your addon ctx

Example (you can find exmaple in <wowtest/pb-wow-test.lua>)

local _, ADDONSELF = ...

local luapb = ADDONSELF.luapb
local person = luapb.load_proto_ast(ADDONSELF.pbperson).Person

local msg0 = person()

msg0.name = "aa"
msg0.id = 1

print("serialize: name " .. msg0.name .. " id " .. msg0.id)

local t = msg0:Serialize()

assert(#t > 0, "size of t > 0")

local msg1 = person()
msg1:Parse(t)

assert(msg1.name == msg0.name, "name not equal")
assert(msg1.id == msg0.id, "id not equal")

print("deserialize: name " .. msg1.name .. " id " .. msg1.id)

Use as an dependency (Optional for LibStub)

local luapb = LibStub:GetLibrary('luapb')
