Ruby InstructionSequence.base_label用法及代碼示例

base_label()

返回此指令序列的基本標簽。

例如，使用 irb：

iseq = RubyVM::InstructionSequence.compile('num = 1 + 2')
#=> <RubyVM::InstructionSequence:<compiled>@<compiled>>
iseq.base_label
#=> "<compiled>"

使用 ::compile_file ：

# /tmp/method.rb
def hello
  puts "hello, world"
end

# in irb
> iseq = RubyVM::InstructionSequence.compile_file('/tmp/method.rb')
> iseq.base_label #=> <main>
