lua虚拟机字节码修改,Lua-制作字节码

So, I've been asked to make a bytecode for the simpliest code:

print("Hello, world!")

But I have no idea how and I can't seem to find any information on how to make one... Can someone please help? I use Lua for Windows as a compiler. Thanks a lot

You can do it from Lua without luac using string.dump. Try for instance

f=assert(io.open("luac.out","wb"))

assert(f:write(string.dump(assert(loadfile("foo.lua")))))

assert(f:close())

If the code to be compiled is in a string, use load(s).

You can also save the file below as luac.luaand run it from the command line:

-- bare-bones luac in Lua

-- usage: lua luac.lua file.lua

assert(arg[1]~=nil and arg[2]==nil,"usage: lua luac.lua file.lua")

f=assert(io.open("luac.out","wb"))

assert(f:write(string.dump(assert(loadfile(arg[1])))))

assert(f:close())
