erlang的abstract_code代码

在看了霸爷的 erlang的abstract code之后，自己动手实验了一下，效果如下：

[liufan@liufan abstract_code]$ erl -s hello -s erlang halt
Erlang R16B01 (erts-5.10.2) [source] [64-bit] [smp:4:4] [async-threads:10] [hipe] [kernel-poll:false]

"hello world"
[liufan@liufan abstract_code]$ cat hello.erl 
-module(hello).

-export([start/0]).

start() ->
	io:format("~p~n", ["hello world"]).
[liufan@liufan abstract_code]$ erlc +debug_info hello.erl 
[liufan@liufan abstract_code]$ erl
Erlang R16B01 (erts-5.10.2) [source] [64-bit] [smp:4:4] [async-threads:10] [hipe] [kernel-poll:false]

Eshell V5.10.2  (abort with ^G)
1> rp(beam_lib:chunks(hello, [abstract_code])).
{ok,{hello,
        [{abstract_code,
             {raw_abstract_v1,
                 [{attribute,1,file,{"hello.erl",1}},
                  {attribute,1,module,hello},
                  {attribute,3,export,[{start,0}]},
                  {function,5,start,0,
                      [{clause,5,[],[],
                           [{call,6,
                                {remote,6,{atom,6,io},{atom,6,format}},
                                [{string,6,"~p~n"},
                                 {cons,6,
                                     {string,6,"hello world"},
                                     {nil,6}}]}]}]},
                  {eof,7}]}}]}}
ok
