Lua-制作字节码 [英] Lua - make bytecode

问题描述

所以，我被要求为最简单的代码制作一个字节码:

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

print("Hello, world!")

但是我不知道该怎么做，我似乎也找不到关于如何制作一个人的任何信息...有人可以帮忙吗?我将Lua for Windows用作编译器.非常感谢

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

推荐答案

您可以使用string.dump在不使用luac的情况下从Lua进行操作.尝试一下

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())

如果要编译的代码在字符串中，请使用load(s).

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

您还可以将以下文件另存为luac.lua并从命令行运行它:

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())
