fix Ruby’s last two examples, which were incorrect |
Ruby: delete the more verbose file-reading example, as the next example is equivalent and simpler |

An implementation that reads and prints the file the code is stored in (which violates some definitions of “quine”): |
|||
One (maybe a bit verbose) version, to be appended to the end of any file. This doesn't work in IRB, because it isn't a file. |
|||
<lang ruby> |
<lang ruby>puts open(__FILE__).read</lang> |
||
f = File.open __FILE__ |
|||
f.each_line do |line| |
|||
puts line |
|||
end |
|||
f.close |
|||
</lang> |
|||
As the above implementation depends on the code being saved in a file, it doesn’t work in IRB. |

or |
|||
<lang ruby> |

puts open(__FILE__).read |
|||
</lang> |
