Is it possible to see the ruby code in a proc?

Question

p = Proc.new{ puts \'ok\' }

Is is possible to see the ruby code in the proc?

inspect returns the memory location:

Answer 1

Do you mean the original source code or its bytecode representation ?

For the former you may use standard Proc's method source_location

p.source_location
=> ["test.rb", 21]

and read the appropriate lines of code.

For the latter it may come handy the RubyVM::InstructionSequence and its class method disassemble:

irb> RubyVM::InstructionSequence.disasm p
=> "== disasm: 
=====\n== catch table\n| catch type: redo   st: 0000 ed: 0011 sp: 0000
cont: 0000\n| catch type: next   st: 0000 ed: 0011 sp: 0000 cont:
0011\n|------------------------------------------------------------------------\n
0000 trace            1                                               
(   1)\n0002 putself          \n0003 putstring        \"ok\"\n0005 
send             :puts, 1, nil, 8, \n0011 leave            \n"
