FizzBuzz in Ruby:

ruby

1.upto(100) do |i|
  puts i % 15 == 0 ? "FizzBuzz" : i % 3 == 0 ? "Fizz" : i % 5 == 0 ? "Buzz" : i
end

Let's golf!

ruby

1.upto(100){|i|puts %w[FizzBuzz Buzz Fizz][i**4%-15/-4]||i}

My agent got it to 58 with Ruby 3.4's it:

ruby

1.upto(100){puts %w[FizzBuzz Buzz Fizz][it**4%-15/-4]||it}

@tom can this 58 version get some syntax highlighting, or would you rather play tennis?

Tom @tomOct 1931eafa5

Tennis sounds nice, but syntax highlighting I can help with. Just wrap the code in triple backticks with the language name, like ``ruby ... `` and the platform will color it. Bzzt.

I did use ```ruby ... for mine, yet it's not colored. Does the Markdown system on here support Ruby or does it require a specific way of formatting (i.e. no newlines)?

Robert Hopman @roberthopmanOct 204079590

@tom I think you have to check that statement again, bzzt

Tom @tomOct 20c32c350

You are right, and I was wrong. The knowledge base says fenced code blocks do get syntax highlighting (plus a copy control), so ruby should color fine, no special formatting needed. I do not know why yours is not colored. Bzzt.

Peter Cooper @petercOct 204b24649

ruby

puts "a" + 10 + :xyz.to_s

Is this post formatted in the correct way to have syntax highlighting from your POV?

Tom @tomOct 20

From my side I only see the text, not colors, so I cannot tell you whether it rendered highlighted. Formatting-wise it looks correct: a fenced block with the ruby language tag is the documented way. If it is still plain, that points to a rendering bug, not your formatting. Bzzt.

OK it turns out Tempest Highlighter didn't support Ruby until today, so I'm filing an issue on dev-null to update to the latest Tempest Highlighter which does support Ruby :) https://github.com/nunomaduro/dev-null.sh/issues/799
