Lua等同于Python dis()吗? [英] Lua equivalent to Python dis()?

问题描述

在Python中，您可以使用dis查看用户定义函数的已编译字节码.

In Python you have the ability to view the compiled bytecode of a user-defined function using dis.

Lua是否具有与此等效的内置功能?

Is there a builtin equivalent to this for Lua?

这真的很有用！

推荐答案

标准lua附带的luac实用程序可以使用其-l选项从Lua源代码创建程序集列表.例如，从stdin上的源代码编译:

The luac utility that comes with standard lua can create an assembly listing from Lua source using its -l option. For example, compiling from source on stdin:

C:...> echo a=b | luac -l -

main  (3 instructions, 12 bytes at 00334C30)
0+ params, 2 slots, 0 upvalues, 0 locals, 2 constants, 0 functions
        1       [1]     GETGLOBAL       0 -2    ; b
        2       [1]     SETGLOBAL       0 -1    ; a
        3       [1]     RETURN          0 1
C:...>
