RubyVM::InstructionSequence#absolute_path -> String | nil (3019.0)

self が表す命令シーケンスの絶対パスを返します。

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

RubyVM::InstructionSequence#label -> String (3019.0)

self が表す命令シーケンスのラベルを返します。通常、メソッド名、クラス名、 モジュール名などで構成されます。

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

例2: RubyVM::InstructionSequence.compile_file を使用した場合

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

# irb
> iseq = Ruby...
...VM::InstructionSequence.compile_file('/tmp/method.rb')
> iseq.label # => "<main>"

例3:

# /tmp/method2.rb
def hello

end

Ruby
VM::InstructionSequence.of(method(:hello)).label
# => "hello"
