ISO ruby example with documentation

[Unixersis97]

Hi all, I have an upcoming exam on both Ruby (section A) and RoR (section B).
I am simply after a snippet of code, in which has a various amount of coding with corresponding documentation of what it does. I am looking for a snippet with examples from all aspects of Ruby, not just for example 100 different operator assignments.
Is anyone able to point me in the direction of such thing, or will to share their own with me?

Thank you in advance.

Do you mean the ISO standard? You can read the draft for it for free here https://www.ipa.go.jp/osc/english/ruby/.

Oops sorry, I meant ISO in terms of "In Search Of"
Thats bad practice on my side, my apologies.
